Heat pump performance
The performance of a heat pump at a set temperature condition is referred to as the coefficient of performance (COP). It is defined as the ratio of heat delivered by the heat pump and the electricity supplied to the compressor.
Higher COPs equate to lower operating costs. More higher COP, more energy saving.
COP is highly dependent on operating conditions, as to the ambient temperature condition, the COP data varies. This is Linsam heat pump COP chart, it at 7℃/35℃ COP of 4, which is produced according to standard of CE and EN14511.
Main Components
Compressor
Our products adopts America Copeland scroll compressor for bigger heat pump and Panasonic compressor for smaller ones,, special designed for heat pump, working high efficiency.
Electronic expansion valve
With branded Sanhua expansion valve and combine with our company’s control system, we have developed a special electronic expansion controller that uses digital technology to adjust the refrigerant according to temperature factors to achieve the best flow rate effect and achieve higher COP.
Electrical control system
With project control function, it can easily control the circulating pump, water compensation, water supply, auxiliary electric heating, PID automatic defrost. Users can set different parameters according to different project needs, and automate the entire system.
Shell and tube heat exchanger
Linsam heat pump adopts high-efficiency shell and tube heat exchanger, the heat exchange area is 3.7 times that of bare tube, its unique design and compact spiral structure of the heat
exchanger ensures the full heat exchange of the refrigerant.

Frequently Asked Questions
What kind of care is needed for the heat pump?
There is no need, just clean up debris and snow around the heat pump in time.
What compressor your equipment have?
For all our products, best quality parts are adopted to assure heat pump good quality and good performance, like this compressor, always adopt branded America Copeland compressor or Japan Sanyo/Daikin compressor or Danfoss compressor.
What is the service life of the heat pump?
Linsam heat pumps are up to 25 to 30 years service life. During their lifetime, approximately 15 to 20 years is usually necessary to replace the heat pump compressor.
Are heat pumps noisy?
No. Heat pumps are generally not noisy. Noise is marginally higher than ambient background sound, and usually not annoying.
Do the products have CE?
Sure,all products are CE approval products, we produce according to international standard, products export to European market.
What is the cost of heat pump operation?
The only cost is the charge for the electricity required compressor and circulation water pump. It based on how many kilowatts are required for your house, generally heat pump is the most efficient way to heat your house, and you save lots of money. And if a room is well insulated, that will require less kw of heat pump, so you can choose smaller model.
