What is Air Source Heat Pump?
Air source heat pump also called air to water heat pump. KLR air source heat pump utilize the out air energy to heat up the water for home heating and domestic hot water, even it can do cooling for house. Air source heat pump is advanced energy saving and zero emissions Hydronic Systems for home. It use R290 or R32 green refrigerant, work efficiently even -25℃low ambient temperature as using EVI inverter technology. It’s Intelligent defrosting function, Anti-Freezing protection and smart control system let user comfort in Cold Climates.
KLR air source heat pump energy savings up to 47% compared with natural gas condensing boiler, energy saving 70% compared to using electric baseboard. At the same time, KLR heat pump can work with Solar Photovoltaic together to make further energy saving.
KLR air source heat pump passed CE, CB,UKCA,KEYMARK, SG-READY the international standard. We have been selling to large number units to different countries and markets, like Germany, Poland, Sweden, Norway, France, Belgium, UK, South Africa, etc.

KLR heat pump have smart controller to monitor and operate the heat pump units, it built in Smartphone App WIFI Control, RS485 communication, have different modes like,hot water mode, heat mode, cool mode, holiday mode etc to meet customers usage.
Multiple Applications For KLR Air To Water Heat Pumps
- Home Heating: KLR heat pumps absorb air heat energy to heat up water for house heating, it can work with radiators, baseboard and water fan coil units.
- House Cooling: Summer time, KLR air to water heat pump change to cool mode, cool the water and go through fan coil for house cooling, it very high efficiency and reliability.
- Domestic Hot Water: KLR heat pumps not only can do heating and cooling for house, but also can supply the hot water for family or commercial use.


Solar Photovoltaic And Heat Pumps Integration
KLR air source heat pump is designed for work with PVT modules directly, using solar energy to power the heat pump, no need inverters or batteries. Heat pump get the free energy from outside air, Solar PV is get the the energy from sun, air and sun are sustainable energy of nature, This perfect combination is the best heating and cooling method for home.

Widely Applications For Air Source Heat Pumps
Heating and cooling for Residential apartment buildings, single-family homes, individual house, condos
Office buildings, Supermarket, Hospitals, Hotels, resorts,Breeding industry and industry application.
Yes, KLR air source heat pump Save 60-75%, when compared to traditional heating systems. Worth to try.
KLR air source heat pumps are made via strict quality control production,combined with DC inverter technology, using Inverter compressor and DC fan, KLR air source heat pump always super quiet operation.
Air source heat pump utilize our air heat energy to heat up water, so ambient temperature too low, heat pump efficiency will affect a lot, when ambient temperature low than minus 10 degree, the heat pump performance drop down, at this time, it can not heat up fast, so auxiliary heat as a spare heater is absolutely necessary.
Yes, KLR heat pump have cooling mode, it can cool your house in summer time.
Average air source heat pump price about 3000USD to 7000USD. Many reasons cause the price different. Like brands, functions, including installation or not, warranty term, delivery. So you need to confirm further information with sales person.
