  Product DescriptionA clear path to net zero energy for CO2 efficient heat pump water heaters.Save energy with a CO2 hot water heat pump system1. 5 times more efficient than traditional electric water heaters2. Allow off-peak electricity use3. Higher first hour rating than all heat pump water heaters4. Faster recovery after pumping hot water5. Hot water production down to -20°F and below6. Provides hot water temperatures up to 175°FEfficient operation: how a CO2 heat pump system worksA CO2 heat pump water heater is a two-part system that includes a tank (usually placed indoors) and a heat pump unit (usually placed outdoors, up to 66 feet from the tank). A heat pump works like a reverse air conditioner, drawing thermal energy from the atmosphere and applying it to the water in the tank. This technology is already used in industrial applications as well as residential water heaters around the world.A CO2 heat pump water heater works just like a conventional heat pump, except it uses carbon dioxide as the refrigerant. Due to the unique properties of CO2, CO2 heat pumps operate very efficiently over a wide temperature range. It is capable of extracting heat from the air all the way down to -20°F and above in one heating stage, raising the water temperature to 150°F at a rate of 0.3 gal/min. The result is a system that requires significantly less electricity to heat water than conventional hot water systems, and operates without backup coils in a very wide range of climates.While CO2 heat pump systems are perfect for replacing existing gas or electric hot water tanks in any residential or multi-family application, the ability to operate at low outside temperatures and still provide hot water at 150°F means the same system can be all Solutions for today's new low-energy homes.CO2 heat pumps use carbon dioxide as a refrigerant, which is harmless to ozone and does not contribute to global warmingHeat pumps use a small amount of energy to transfer heat from one location to another. In a CO2 heat pump system, the heat in the air is absorbed by the natural refrigerant CO2, which is ozone friendly and does not cause global warming.Warm gaseous refrigerant circulates through the system through a compressor. As it passes through the compressor, its pressure rises and so does its temperature. This hot refrigerant then passes through a heat exchanger to heat water, which is then sent to a storage tank.Combination system: DHW plus space adjustmentCO2 heat pump water heaters are capable of delivering 15,000 btu/hr and can be designed as a system that provides all domestic hot water (DHW) as well as hot water for space conditioning. This is accomplished with one loop powering the DHW mixing valve to bring the temperature down to 120°F, and the other loop feeding a standard heat exchanger with hot water radiators, radiant panels or forced air fan coils.For homes with a design temperature of 12°F or higher and a heat load of 8kbtu/hr or lower, this can be the entire DHW and space conditioning system. Additional on-demand water heater systems can be added to designs for homes with larger heat loads, or a backup system can be used to provide extra capacity for extreme weather events or large homes where the default CO2 heat pump system is available on all but the coldest days. can provide.Multifamily domestic hot water project and new 119 gallon tankThe efficiency of CO2 heat pump water heaters is attractive for new multifamily projects, but 43 and 83 gallon tanks are difficult to fit into buildings due to space constraints. With new 119- to 505-gallon tanks, that changes. Over the past few years, large building designs have been developed and tested combining these units into heat pump arrays serving larger primary storage.A decade of CO2 heat pump success and counting..The ability of CO2 heat pumps to efficiently provide large amounts of very hot water, Japan accepted and developed the technology as the preferred method of providing large amounts of hot water for "bath culture".Japan's success has brought success to the rest of the world, as most European and Asian vending machines and other refrigeration equipment are rapidly turning to CO2 heat pumps as "a new way to reduce operating costs."Common problem:1. What is the operating temperature range?CO2 HPWH operates at temperatures from -20F to 110F2. What is the hot water recovery rate?CO2 heat pumps are capable of producing 131 to 176 degrees Fahrenheit water at 16 to 23 GPH (depending on heat pump settings).3. Can CO2 be used as a combination of domestic hot water and radiant heating systems (Combi)?Of course. Your heat load must be below 8,000btu/hr, with a design temperature above 12F, and C02 recommends that you use at least 20 gallons of domestic hot water per day to maintain tank stratification and efficiency.4. What is the coefficient of performance (COP) of the three-electric system?It ranges from 2 to 5 depending on the ambient temperature. As the weather gets war
