Storing heat may be the last thing you think of when turning on an air conditioning unit, but one model takes advantage of the sweltering weather to heat water while cooling the air. The aptly named Air Conditioner Water Heater, or ACWH, from Hotspot Energy has a condenser unit that sits outside of the building, collecting heat that the air conditioner compresses and expels from inside. The heat passes through a copper heat exchanger that connects to a home or building’s hot water tank. According to the company, the unit can cool a 1000-square-foot room and heat about 100 gallons of water per day. At its peak, the ACWH can provide 18,000 BTU, or 1.5 tons of cooling using 1333 watts per hour. Heating water while cooling a building can help save energy, since the heat recovery process eases the load of the air conditioner. The unit has to be installed relatively close (ideally within 150 feet of) the water heater, however, and only heats water when the air conditioner is running and there is enough hot air to warm the water.

Using the unit on a mild summer day won’t make a significant dent in water heating costs, but it could have an impact for homes with multiple residents who use hot water throughout the day to shower or wash dishes. HotSpot Energy, which makes the ACWH, sees buildings as large solar thermal collectors, ripe for gathering heat. how much is a two ton ac unitAlthough the unit can be installed anywhere, it was designed with the southern U.S. in mind, where many residents use air conditioners during spring and fall, in addition to summer. home hvac units costCommercially, the company envisions restaurant kitchens, laundromats and server rooms benefiting from their technology.how much energy does window unit ac use Frigidaire Gallery 8,000 BTU Smart Room Air Conditioner with Wifi Control

The AQUEFIER® Heat Recovery Unit captures waste heat discharged from an Air Conditioning or Heat Pump system, and transfers that heat into a water heater tank, thereby creating low cost hot water for domestic use. Cut Cooling Cost up to 15% Cut Water Heating Cost 50% or more Added together, that’s a savings of up to $700.00 a year for you!View Aquefier brochureHeat Recovery Unit Installation Instructions (Video) I spoke with you yesterday about the noise (WA-WA) that was coming from my ECU.As I mentioned, this has been going on for 10 years and I am constantly inserting small wood shims to stop the vibration.You suggested that I “isolate” the box on the wall by adding a foam pad in between the box and the wall.My wife had a pad of high density ¼” foam that I cut into 4 strips and after I backed out the mounting screws as you suggested, I inserted the foam strips around the sides of the box and then tightened the screws. After all these years of a Chinese water torture all day and all night, the sound is totally gone.

I even put my ear to the interior wall just inside where the A/C unit is and all I hear is the compressor. You really saved me (at least my sanity or what’s left of it). Sure wish I would have called you years ago.Dan Clark, Punta Gorda, FLI can't thank you for all your help in the replacement of my Hot Water Recovery pump. Doing business with you was a pleasure and rest assured that I will pass it along to my anyone in need of your services. The phone calls in "trouble-shooting" my problem, ordering the pump, and then walking me thru the installation procedure.......well you made it surprisingly simple. I'm not sure if I mentioned to you, but this is my third home that I have installed the Aquefier Hot Water Recovery "system" and I would not have a home without one! Having my A/C heat my hot water for FREE, making my A/C run/cool even more efficient, and above all, lowing my electric bill, especially here Florida, it's a "win-win" for me. I've actually been a walking advertisement for this unit ever since my first install.

It is simple GREAT! Cliff & Connie, Ocala, FLDear Jim: I recently purchased a heat recovery unit model # R6K-PE-410 that is distributed by your company. unit form a local air conditioner company. After much debate with the air conditioner company, I called you for information as to why the unit was not functioning correctly. (Your name, phone number and e-mail was on the booklet that came with I want to thank you for your prompt and professional response. When the phone conversations I had with the air conditioner company about the problem of wrong installation didn't solve the problem, you offered to come over to my home and meet with the installers to show them what that did wrong. After they corrected the problem under your supervision, I am proud to say it is functioning as it I want to thank you S-O-O much for your help. It is a wonderful unit and I have hot water all the time and my hot water unit is turned off completely for the summer. I will let you know how much my Duke Energy bill decreases next month.

If you know anyone that is hesitant on purchasing this unit, please tell them not to wait. There is much more hot weather ahead in Florida and other states. Why would anyone want to blow all that hot air in the yard when you could heat your water for free. Thanks again Jim, and keep up the good work. "I've saved money on my electric bill every year with my heat recovery unit. After 21 years of savings, I just had to have one installed when I moved to my new home. Now with our electric prices still climbing, I'm glad to know that every time I hear my air conditioning come on, I'm still saving money. You need to get one for your home too.!!"Don F., Home Owner, Largo, Fl I just wanted to let you know that my builder installed one of your heat recovery systems when we built the home in 2004. It is a great system. My home is 2500SF heated and I live here with my wife and three kids. We are able to completely turn off our electric hot water heater in early May and keep it off until early October.
