Two independent refrigerant system and New Heat Recovery system built inside Kolant Multisource heat recovery heat pump
Two compressors built inside with new heat recovery technology, combined with the essence of KOLANT’s more than 20 years of air-cooled heat pump design and heat recovery technology for cooling, heating and DHW function in one solution. The heat recovery function will start recover heat to domestic hot water in both cooling and heating mode.
AC heating/cooling and DHW function will work together, no need switching AC and DHW, so when require one function, no need to stop other function. The system is much more reliable than other multifunction heat pump switching system.
Kolant professional cooling solution use groundwater or cooling tower water through a combination of “water cooling + air cooling” . The water central cooling system has small air temperature difference with room temp, which makes the room air less dry and more comfortable. The water central heating can use various room terminals such as undefloor heating system or radiators and creat a healthy living environment of “warm feet and cool roof”.
- Solar ready: Compatible with solar thermal panels to be the second heat source of the system.
- 0 cost free hot water: Domestic hot water is available all year round with free cost.
- Healthy heating: Suitable for floor heating, radiator heating or fan coil heating.
- Comfortable Cooling: Cooling function is available when it is necessary and suitable for fan coil cooling or area cooling.

Kolant multi source heat recovery multifunctional heat pump adopts the latest full heat recovery technology from Spain, combining the essence of Kolant’s 20 years of air-cooled heat pump design and heat recovery technology. It meets the needs of both cooling and heating, and provides “free” domestic hot water around the clock during summer (with heat recovery during cooling). Compared to traditional household central air conditioning and hot water equipment, it saves over 40% in operating costs
Precise Heat Demand Match
The heating capacity of KOLANT DC inverter heat pump can be precisely regulated from 20% to 100% according to the actual heat demand. Accordingly, the water temperature in the system will be steadily controlled with a very small deviation of no more than 0.5℃ so as to create a comfortable living environment.
Wider Operating Range
KOLANT DC inverter heat pump can reliably and efficiently run with a bigger operating range. For example, even when the environment temperature as cold as -20℃ , the heat pump still can provide warm water with high water temperature and high heating output. However, normalheat pumps even can not work in this situation.
Energy efficiency class A+++
KOLANT DC inverter heating technology makes a very high energy efficiency within all the permitted operating range. For example, when the ambient air is not so cold and the heat demand is not so big, the heat pump runs with low heat output but a particularly high efficiency. However, when ambient air is extremely cold, the heat pump runs with full load to reduce or eliminate the aid of the booster heater. The intelligent control system is always trying to maximize the efficiency of the whole heating system. As a matter of fact, all KOLANT DC inverter heat pumps have energy efficiency class A+++.
Heat Recovery Function is working at both Heating and Cooling mode to Save cost
With 35 years experience in heat pump field, Kolant use the newest heat recovery tech in this Multisource heat recovery multifunctional heat pump. The heat recovery can heat DHW(SHW) tank water to maximum 60°C in both cooling and heating mode. With free cost SHW water, it can also improve heating and cooling efficiency.
Multi function for heating cooling and DHW together
Professional cooling design to use geo or cooling tower
Creative design to combine water and air source together
water system temp difference small with stable water temp for more comfortable central air conditioning
water heating use underfloor heating to create warm feet and cool head for more healthy life

Smart WIFI control
By downloading our APP in your mobile phone, it is possible for you to conveniently control a DC inverter heat pump from KOLANT at any time, anywhere. Just imagine that you turn on your heat pump and set it to a comfortable temperature before you leave office, then you will enjoy the pleasant environment as soon as you get home, It is fantastic, isn’t it?
System Temp control
Kolant heat pump Temperature control system can adjust the outlet water temperature with room temperature controllers in different zones, which can be turned on and off as required, meet different temperature requirements and usage habits, and output on demand without waste.
Wide Working Range
Kolant Heat pumps stand out for their remarkable ability to operate stably in a wide range of ambient temperatures in both cooling and heating.
In summer, they deftly extract heat from indoor air, releasing it outside to cool the interior. When winter arrives, they reverse the process, drawing heat from the cold outside air and transferring it indoors for warmth. This adaptability is made possible by advanced compressors and intelligent controls. They adjust operation in response to temperature changes, ensuring consistent performance regardless of extreme heat or cold.
Kolant Intelligient Defrost
Kolant Intelligient Defrost function is a big step to improve heat pump performance. Through real-time monitoring of the heat pump working, the system in cold regions can perform intelligent defrosting based on the real-time operation to improve heating efficiency in winter.
High quality components, long lifetime
All the key components are from leading suppliers to make sure the quality and lifetime. For example, the DC inverter compressors are from Panasonic, the high efficiency plate heat exchangers are from Swep etc.
