rheem 120v heat pump water heater

rheem ruud azappliance furnace Is there a reason why manufacturers put such small output compressors on these tanks? We have an older home, and our domestic hot water was originally supplied by a stand alone oil-fired tank. What makes you think otherwise? But what about the other 54% of water heaters across the nation, the 64 million, mostly natural gas powered, machines that are heating the nations water? "you want how many places on my panel?". They're both similar insulated storage tanks, so standby losses would be similar, and it takes a certain amount of BTU to heat water to a given temperature delta. Heat pump water heaters are a rare example of a silver technological bullet. Amrutas organization is part of the Advanced Water Heating Initiative, an initiative studying and promoting efficient water heating. We like the water when we need it so don't use heat pump only mode. Expensive, but very high efficiency. The 43-gallon Sanden still appears to be the only game in town for a lowboy HPWH. Not sure why you think existing homes already have 240V wiring for a water heater. Of course you could just add a mixing valve to any of these. It's just that the 120V HPWH will take twice as long to do it. Its doable but adds additional work and expense. So either they misunderstood your question or you misunderstood their answer, or their data sheet is wrong. These rods are the same technology used in standard electric water heaters and require a lot of electricity. THIS!

Presumably a 2 person household would use notably less. I completely agree. The industry is ripe for a superior product. Until now, heat pump water heaters have only been available with 240 volt electrical connections. Even in the north its a total no brainer. Efficiency in and of itself is cool.

But how we heat water matters greatly in our efforts to decarbonize.

Second.

It's on a dedicated 30A 240VAC circuit. Through a spokeswoman, Zimmer said, GE Appliances will be a full-line manufacturer to meet the needs of the industry. Paloma Co., Ltd. of Nagoya, Japan, acquired the iconic Rheem brand in 1988. If not, does any body have a pointer to Rheem/AO Smith/GE web site with 15A/120V HPWH models? It's like they don't want to sell many of them. Naturally, the subject of heat-pumps leaps to mind and I'm trying to imagine a case where one of these makes sense. I don't want a 45-55 decibel hot water tank within the house envelope. Same boat. The DOE ratings for 50 gallon water heaters assumes an average 3 person household with over 60 gallons of usage per day. When typing in this field, a list of search results will appear and be automatically updated as you type. That can get expensive. "Many cities throughout the state have gas bans and efficiency requirements, which make HPWH the ideal option for new construction and replacement. Manufacturers are trying to compensate in several ways. The only case I can make is not from a dollars standpoint or even climate but to get the NG combustion products out of my house.

In addition, our basement level is fully finished with the electrical panel located at one end and utility room at the other; even if we had sufficient capacity for a 240-volt tank, running a new dedicated circuit is not in the cards. I just put a thermocouple on the inlet and outlet pipes of my existing WH. As recently as March, a spokeswoman for GE Appliances confirmed the company was out of the business and made no mention of the development of what appears to be a retooled GeoSpring HPWH. Water heaters are the, in a typical household in the US, and a clean version of this boring technology might help save the day and our planet. Any new homes will continue to have the same setup. I might just wait until these come on the market now. Opinions and comments published on this site may not be sanctioned by and do not necessarily represent the views of CleanTechnica, its owners, sponsors, affiliates, or subsidiaries. With this new version of the heat pump water heater, half the nations gas water heaters with a 120 volt electricity supply can easily be replaced with heat pump water heaters without running a new electrical line. 120 volt heat pump water heaters come with a mixing valve integrated into the water heater itself. That's a moonshot in a retrofit. It seems like the concern is panel space, not actual load. At the start of each cycle, it draws in the order of 350 to 400-watts, and you'll see that slowly climb to roughly 700-watts by the time it finishes its job. Going to cost me $1500 to put in a sub panel and dedicated circuit. Seems fine. This higher temperature will extend the hot water in the tank and thus the 120 volt water heater will be able to keep up with demand even though it has a slower recovery without the electric resistance backup. The content produced by this site is for entertainment purposes only. I'm already stuck with a Rheem hybrid water heater that stopped working in heat-pump mode after a couple of years. The thermostatic mixing valve is an attractive option since then you could heat the water up hotter when there is plentiful solar/wind power and let it cool some when electricity is expensive while still maintaining constant temperatures. Most of them aren't gonna have 220v circuits run to allow for electric appliances. The complete source for building, designing, and remodeling green homes. The newest development in heat pump water heating is the production of a 120 volt 15 amp version. Cision Distribution 888-776-0942 Even replacing the Hybrid every 10 years would result in thousands of dollars of overall savings, over a 10 year cycle. Try installing an electric tankless. General Motors & Livent Enter Long-Term Lithium Hydroxide Supply Agreement, U.S. My guess also is it's assumed people would not want to convert from gas to electric. Induction would be no more than 85 to 90 per cent efficient due to the related electronics/power supplies (that waste heat ends up in the ambient air and not the water). Become a GBA Prime member and get full access to GBA articles, enyclopedia, videos, CAD library, and more. Only 2 people in the house, so the heating bills are tiny anyway and it's hard to justify an ROI. Rheem provides our California customers with a comprehensive solution to meet both their sustainability goals and hot water performance needs.". When you move from the 240-volt to the 120-volt configuration you are giving up energy use on the input side, so it takes longer for tanks to recover, especially those that are operating on pure heat-pump operation, and there is a tendency to get lower first-hour ratings because of that difference, he told the webinar audience. The 120v model is the highest rated in the NEAA study test. Provided you do have space in the panel, converting a 120V electrical run to a 240V is often very simple. Worries about overcooling? Unless there are strict measures to encourage adoption these will have to be for true believers.

The Shared Circuit model is demand response ready with built-in EcoPort (CTA-2045 port) which easily connects to utility programs for additional energy cost savings. Another issue is space on panels - to the extent there is any extra space on a house originally set up for gas WH, the space for the 240 may be going to an EV charger, impacting the feasibility of converting from Gas WH to Electric. But how much does that impact the actual energy cost? across the nation, the 64 million, mostly natural gas powered, machines that are heating the nations water? Lots of paperwork on that one. This can be expensive and often extensive in older homes. I guess if you wanted to install the water heater in your bathroom or kitchen, this might interest you. GE has not announced when its version might be on the market, and its not clear where the new models will be sold. These water heaters are just coming to market. Since they already have an existing supply of electricity, its easy to switch them out for the new 120 volt heat pump water heaters. As a general rule that's likely the case. My fear is not understanding people who don't buy these things, and then creating a bad, hard to overcome, image of them. Copyright 2021 CleanTechnica. Has anyone proposed a triple system? Thats something we have to factor in as we think about these conversions., The company didnt discuss its reasons for jumping back into HPWHs except to note that the industry is evolving. If I use a HPWH, for example a Rheem that claims 375% efficiency that number is $0.18/day.

Can 120 Volt Heat Pump Water Heaters Still Heat All the Water I Need? But the HP is pulling heat out of room air which has been heated by another heat pump. Ive already written a full CleanTechnica article on the topic in which I called them game changing machines (this happened to be my best read CT article ever and editor, Zach Shahan, laughed that an article on water heaters was the top read for the week).

A roof-mounted HP isn't the greatest.

An induction water heater is no more efficient than a regular electric water heater. Since then I've occasionally called local plumbers and 95% of them have said, "We don't work on hybrid water heaters." Directionally it is the right idea, but I think will fail as a consumer product. Is it just size considerations? You must be a magazine subscriber to access this feature. Plugging one of these 15a 120v heaters into an existing 15 amp or even 20 amp circuit could also be an issue if the circuit is serving other receptacles, appliances or lighting, likely overloading the circuit. Does anybody have any insight into the reliability of the available 240V models? Ive already written a full. Electric resistance would be, for all intents and purposes, 100 per cent efficient. Even though they dont have the electric resistance backup, 120 volt water heaters are still able to deliver all the hot water heater necessary especially for households with 2-4 people in them. My family rewired our water heater to switch out gas for electric heat pump. You're right, upon reflection it's probably uncommon in older homes where natural gas or propane was the fuel of choice for heating. Image Courtesy of New Buildings Institute. JA13 is a California standard for demand response. They can be mfg locally provides work of different skill levels and will still crank out hot water when everything else fails. Well, let's see if it's straightforward. The problem is that ON PAPER isn't the same as IN REALITY. It appeals to me! My 50 gallon, resistance heated tank is in a utility closet within the electric heat-pump conditioned envelope of my home. Zimmer acknowledged some of the difficulties in selling HPWHs, including higher costs when compared to gas models, higher installation costs if panel upgrades are required, and marginal energy savings. I'll have to study that. The issue (as always) will be making sure good system design is taking place. I've been looking forward to them stealing the market for 10 years. How much less depends on how much hot water you use, and what temperature it comes into you house at (depends on climate). I have a 66 gallon AO Smith HPWH with the temp set to 150 and then mix it down to 120 with a tempering valve. For more information, please visit www.rheem.com/ProTerra. This strategy means you have to be more careful with the hotter water and have anti-scald devices on your faucets so the hotter water doesnt hurt you or your kids. Plants love CO2, I'm not going to deprive them. Environmental, Social and Governance (ESG), HVAC (Heating, Ventilation and Air-Conditioning), Machine Tools, Metalworking and Metallurgy, Aboriginal, First Nations & Native American. That's pretty good--better than an investment in the stock market. 2022 The Taunton Press, Inc. All rights reserved. When Can I Get My Heat Pump Water Heater? They are listed on the ProTerra as 15 amp versions. All grants require an EnerGuide audit. The lowest hanging fruit to more efficient water heating is to replace every inefficient, electric resistance water heater with a hybrid electric heat pump water heater. Has anybody been able to buy 15A/120V HPWH from any maker? There are big developments happening in the world of water heating. In my mind its a total no brainer. My understanding is that Rheem is reasonable with warranties. This all occurred circa 2016-2018 though, so maybe things have changed and plumbers are learning how to repair these things. The need for recovery is usually associated with showers taking place concurrently or consecutively. Panel space is also a real problem, but a more general problem for older homes, and not brought on solely by the water heater issue. This is appealing. I'm not sure who they think this is going to appeal to. ProTerra Plug-in comes with a 10-year limited tank and parts warranty. It seems like a no-brainer to me. Ok, I'm so confused - Why are Induction water heaters -not- the next greatest thing invented for reduced energy consumption! That's where my struggle comes in -- where can I find the facts and figures needed to accurately compare a Marathon vs a Hybrid for a 2 person household in reality, since the published numbers show the Hybrid absolutely dominating. Since this thing plugs into a standard outlet, it has to have a max draw of 12A. If consumers want to decarbonize and switch to an electric water heater, the only option they currently have is going for expensive and extensive panel upgrades, she said. From a rough "back-of-the-napkin" analysis, the numbers for both types of units could be scaled per person. The 120V plug-in solves the electrical challenges of replacing a gas water heater. We regret the error. With 4 people, I use 70 kWh per month, except in May spring when my solar water heater helps to cut the consumption to 35 kWh. The realtors will kill this one. It depends on which province you live in. As I remember it, the warranty wouldn't have covered labor at that point (just parts). I can think of several new construction homes in the last 2-3 years with gas WH that do not have 240 run to the WH area - maybe it is or should be required, but it is not enforced or done. From what I gather, the 120V water heaters will have similar COP to the 240V water heaters, so similar performance. And how much money and carbon emissions you'd save depends on regional electricity price and the emissions profile and your regional grid. Also fine without 240V. Wes, if your heating and cooling energy use is similar, then the summer advantage and the winter loss offset each other nicely, so your calculated 3.5 year payback will come true. Second, I can't for the life of me see why we don't push, much harder, SDHW. With minimal clearance requirements and the ability to fit in a standard tank footprint, the units were designed for quick and easy retrofit installation, effortlessly fitting in tight spaces. I'm not about to walk into those weeds, I'll leave it for someone else. Get building science and energy efficiency advice, plus special offers, in your inbox. https://www.openadr.org/assets/OADR_CTA2045_Overview%20Webinar.pdf. Storing the water at higher temps to avoid Legionella is appealing.

With the right water heater we can have our cake and eat it too: we can have all the hot water we need, Heat pump water heaters are a rare example of a silver technological bullet. I think the case for it is pretty straightforward. BTW, carbon is a non-issue with me. I'm interested in the 120V HPWH because I do have 120V outlets in my utility room but not enough space for two breakers for 240V in my main panel. For example, Rheem has 4,200 Btu/h compressors on their 240V versions, for both the 15 and 30 amp versions. 2. Providing advanced solutions for California contractors and homeowners seeking a drop-in gas replacement, the ProTerraPlug-in Heat Pump Dedicated and Shared Circuit models boast high-efficiency performance, up to five times of a standard gas water heater, without the need to upgrade the electrical panel for 240V hardwired service. He also volunteers with Electrify Now because he believes that electrifying everything, from transportation to homes, is the quickest path to an equitable, clean energy future. Rheem, A.O.

Renewable energy got a big boost in the Inflation Reduction Act with new long term stability for clean energy investments. But the models under development, and in some cases now in field tests, are designed to run on either a dedicated 120-volt circuit or a shared circuit that also powers other devices. I've lived in 3 homes and none of them had that. All that said, I'd be willing to try again with another unit to reduce the energy use. But how we heat water matters greatly in our efforts to decarbonize. This means that in the end, it will cost the same amount to heat a tankful of water. Given the current insulating technologies, it seems maintaining temp on stored water can be much more successful than it used to be. This water heater is expected to hit the market in the first half of 2022. The development of ProTerra Plug-in HPWH technology began in 2019 with the roadmap to decarbonize California's buildings, which included plans to replace gas-burning appliances with electric versions (CA Title 20). They don't come with a cord and plug, so I guess that's the innovation. You'd use less electricity. Solar & Storage Industry Praises Joe Bidens Targeted Actions on Community Solar, BioLite AlpenGlow Lanterns & Solar Charger CleanTechnica Review. Unlike the other two companies, Rheem is not including an auxiliary electric element in its models. Thats about as specific as Ill get, he said. This mixing valve allows owners to keep their water at a higher temperature and as the water leaves the tank, the valve will mix in the exact amount of cold water needed to ensure the water comes out of the water heater at the correct temperature. (Source) Homeowners will thus get to store their water at a higher temperature and the water heater will make sure its still safe. IF you want wide adoption propose products that achieve this result for people who don't care. What am I missing? Heat pump water heaters only use electric resistance backup when there is a lot of hot water demand and they cant keep up, but this is rare. The issue came up with the publication of a consumer guide to electrification, which mentioned plug-in models that were not commercially available, including the GeoSpring. Electric water heaters are placed inside tight conditioned spaces often like a bedroom closets, kitchen closets, laundry rooms, under the staircase. I live in a green town and people complain all the time about the on demand water heaters. Previously, HPWHs needed 240V hardwired service. ATLANTA, July 18, 2022 /PRNewswire/ -- Rheem, a leading global manufacturer of water heating and HVACR products, is launching two versions of the 120-Volt ProTerra Plug-in Heat Pump Water Heater. This higher temperature will extend the hot water in the tank and thus the 120 volt water heater will be able to keep up with demand even though it has a slower recovery without the electric resistance backup. My only hot water use is for showering (est 2 gal/min * 20 min) and dish washing (5 gal in machine, 5 gal misc), clothes washing is all cold, except for rare occasions. Tom Zimmer, who leads the water heater division at GE Appliances, said on the webinar that it was developing both a 120-volt and a 240-volt GeoSpring model, although he did not say when they might be back on the market. Suppose it's 50 deg F. The numbers go to $1.23/day for conventional and $0.31/day for the HPWH. Given the lower performance, no one in their right mind is going to install this in a utility room just to save the $100 it might cost to have an electrician run a wire 10-20 feet from the service panel. I'm from Canada where you'll need the patience to get a Rheem. If California does force/ convince customers off gas most every house will pushing the limits of their electric service. The Shared Circuit design offers HydroBoost mixing valve that extends the hot water in the tank for maximum output performance and requires no electrical work. They rely on the same technology that makes air-source heat pumps so attractive, but until now they have been limited to models that run on 240-volt current. This need is evolving, and as it starts to include HPWHs (120V or 240V), GE will bring great products to serve those needs. On PEI it is also dependent on your income varying between $1,200 and $1,800. Where they will suffer is in recovery speed, because they only have half the power input to the heat pump. Arthur Smith, a product manager for specialty residential products, would say only that the companys 120-volt plug-in model would be available sometime this year. Capabilities include adjusting water temperature, scheduling and tracking energy usage from a smart phone. Today the company's portfolio of premium brands include Rheem, Intergas, Friedrich, Raypak, Ruud, Eemax, Richmond, Splendid, Solahart and EverHot as well as commercial refrigeration brands Russell, Witt, ColdZone and Kramer, which are part of the Heat Transfer Products Group (HTPG) division. Governor Newsoms new targets will accelerate the deployment of super-efficient heat pumps, helping to keep people safe from extreme heat while cutting their energy President Biden included energy efficient, electric air sourced heat pumps in a laundry list of action steps to tackle the climate emergency, including a Why heat pumps are a cost-effective and climate-friendly solution for extreme heat waves and frigid winters. I've owned two houses, the one I'm in and the previous one, that both had SDHW systems installed by prior owners. It's too much to detail here but with the maintenance/freeze-up issues (even in sunny AZ) they made no sense to me and I removed them both.

Rheem provides an online selector tool to help homeowners identify their ideal HPWH solution. In previous, pre-climate catastrophe times, news about a new type of water heater might be laughable. Water heaters are the second biggest energy user in a typical household in the US, and a clean version of this boring technology might help save the day and our planet. In a recent webinar, Geoff Wickes from NEEA, described how for every 10 degrees you turn up your water heater, above the standard 120 degrees, its as if you get an extra 10 gallons of hot water storage. This would open up the feasible placement of HPWHs a lot. How Do You Charge An Electric Car At Home? And LG has a split model (which I think is also more suitable for space heating). Heating and cooling energy usage is quite similar between winter and summer. In Canada right now, you can't buy one anywhere. It also reduces growth of Legionella as discussed above.

The table below provides all brands available for both 240 volt and 120 volt (120 volt versions noted as emerging). Never mind the plug when they cost as much as a used car! That pays off the initial cost difference in 2 years and completely pays for the Hybrid in 5.

Understanding the hot water usage of the home, helping homeowners choose good low flow shower heads that meet their needs, then choosing the right heater for the job. Looks like Tucson averages 1500 HDD and 4000 CDD, so the contribution would be large, but probably difficult to quantify since it might not directly offset AC use unlike integrated systems. Sure, the more water you heat the more energy you use, therefore the shorter the ROI if the savings are based on energy usage. Another is to include auxiliary heating coils to boost water temperatures when the heat pumps cant meet demand. In conjunction with public utilities like PG&E, SCE and SMUD, the trial leveraged a Rheem ProTerra Plug-in Heat Pump with HydroBoost and LeakGuard (a Shared Circuit model) as the first of 32 HPWHs that were installed in single family homesto prove they sufficiently met demand. Overall results of the study will be released followingthe completion ofproject's remaining installs, but the 120V ProTerra Plug-in unitsinstalled to-date havedemonstratedthey arean ideal, plug-and-playretrofit solution that deliver on homeowners needs. The company sold its manufacturing line to Bradford White, which had been buying the GeoSpring and selling it under its own label, AeroTherm. Have you pursued this avenue? I'd rather they just make the current models more accessible and affordable. So the Marathon-vs-hybrid decision becomes "Do I remodel my house to carve out space for a hybrid". But what about wintertime? The compressor would need a mounting bracket kit for outdoors and be rated for the outdoors but the HVAC world knows how to do these things. Dealing with the emergency replacement problem and helping home owners get plans in place for appliance replacement will be key to these 120v HPWHs making a difference.

At a cost differential of about $700 including tax credit, the payback is about 3.5 years. Smith, and GE Appliances all are working on the plug-in models, with two of the companies saying they should be available this year. I feel much the same. Noise and reliability aside, you'd also get supplemental cooling. I feel your pain, as I also need a lowboy solution. Will the 120V heaters have lower performance when running in heat pump only mode? I'm in Tucson and room temp right now is ~80F. I find this somewhat puzzling. Hardly seems the stuff of the most technologically advanced country on earth. So even if electricity cost three times as much (and I live in Seattle, so electricity is relatively cheap) we'd be paying only a little over a dollar a day, which is down at noise level in the budget. Homeowners who wanted to switch from a gas water heater to a HPWH will be forced to upgrade the electric panel if the panel doesnt have the capacity for a new, dedicated 240-volt circuit. Kevin Clark, a regional manager for the company, said Rheem models had been in test homes for more than a year. It only has a heat pump to heat your water, so it needs less electricity supply (but it still is able to provide all the hot water youll need see below). To learn more read here. For the new house I am building, I decided to skip a HPWH due to the noise level. It would be a California-centric product, at least to start. Even though my family has a 240 volt heat pump water heater, we leave it exclusively in Heat Pump Mode so that were heating water more efficiently and never relying on the electric resistance backup.
