![]() ![]() Until now, heat pump water heaters have only been available with 240 volt electrical connections. The newest development in heat pump water heating is the production of a 120 volt 15 amp version. Both use 240 volts of electricity so making the transition is relatively easy.īut what about the other 54% of water heaters across the nation, the 64 million, mostly natural gas powered, machines that are heating the nation’s water? 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. Heat pump water heaters are orders of magnitude more efficient than polluting natural gas and old electric resistance water heaters, which means families will save hundreds of dollars a year in energy costs and literal tons of CO2 emissions.ġ20 Volt Versions Make Gas Switch-Outs Easier I’ve 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). ![]() ![]() They clean up the way we heat our water and reduce, and potentially eliminate, CO2 emissions from water heating. Heat pump water heaters are a rare example of a silver technological bullet. Heat Pump Water Heaters Are Game-Changing With the right water heater we can have our cake and eat it too: we can have all the hot water we need and save money and not pollute. 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. Until relatively recently, no one thought much about the big tube-like machines with pipes and wires sticking out of them that sit in our closets, basements or garages, and somehow provide all the steamy showers we could ever want.īut how we heat water matters greatly in our efforts to decarbonize. In previous, pre-climate catastrophe times, news about a new type of water heater might be laughable. This opens up the world of efficient water heating to many more households because they won’t have to rewire their homes to make the switch. 120 volt 15 amp heat pump water heaters are set to hit the market (most early next year) allowing homeowners with gas water heaters to easily switch them out for heat pump water heaters without expensive electrical panel upgrades. There are big developments happening in the world of water heating. This water heater is expected to hit the market in the first half of 2022. AOC varies by gallon capacity.Updated: Editor’s note – a previous version of this article stated that the Rheem 120 V water heater was already for sale. 10Based on AOC comparison of 40, 50, 65 and 80 gallon Ruud Ultra Heat Pump with HydroBoost water heaters and standard gas water heaters of similar capacity. 9Based on comparison of 40, 50, 65, and 80-gallon Plug-in heat pumps and standard gas tanks of similar capacity with minimum efficiency. ![]() 8As compared to standard integrated heat pump water heaters. 7Based on AOC comparison of 40, 50 gallon Ruud Ultra Heat Pump water heaters and standard gas water heaters of like capacity. 6WiFi broadband connection and Ruud Contractor App required connection between water heater and app dependent on external factors beyond Richmond’s control. Energy Savings of a 50-gallon Plug-in compared to a standard gas water heater of like capacity with minimum efficiency over 10 years. 5Based on comparison of a 50-gallon Ruud Hybrid and a standard electric tank with minimum efficiency. 4Based on comparison of the annual operating cost of a 40- and 50-gallon Ruud Hybrid model which assumes the unit is on constantly throughout the year against the energy needed to power a single 100-Watt incandescent light bulb constantly for one year. Ruud leak-sensing data testing under a vacuum lock using 50-gallon tank, no expansion tank, average tank pressure of 40 PSI, assuming no additional faucets are opened. 3Applies to Ruud Ultra Hybrid with LeakGuard models only. 2WiFi broadband Internet connection and EcoNet App required Notifications are dependent on external factors beyond Ruud’s control. Note: Leak detection and leak prevention add-on accessories operate differently than built-in features of Premium models. Leak detection and leak protection available as accessory for Plus models. 1Leak detection and leak protection built in for Premium Plug-in Heat Pump with HydroBoost models only. ![]()
