This exciting product brings together the excellent low temperature performance of a Mitsubishi heat pump with a built in swimming pool heat exchanger.

The result is one of the best performing swimming pool heat pumps on the market BWT Power Inverter range heat pumps are fully inverter driven.

They provide high output at low air temperatures and so are ideal for indoor pools as well as outdoor pools

The work well down to -15c

BWT 100M/160M Model


Models 190M to 380T

3. Inverter Driven

BWT heat pumps are fitted with a frequency variator capable of adjusting the compressor and fan speeds.
On the contrary to the compressor and fan(s) in conventional On/Off heat pumps that run at a fixed speed (50 Hz), those in the BWT heat pumps run at variable speeds (11 to 100 Hz), thus allowing the machine to automatically adapt to the heating demand and climatic conditions.
While the outdoor temperature is low, or while the heating demand is high, the Power Inverter® compressor and fan(s) run at high speed, between 50 Hz and 100 Hz).
Inversely, while the heating demand is low, or while the heat pump is running at temperatures around the set point, the Inverter® compressor and fan(s) will run at low speeds (between 11 Hz and 50 Hz).
At low speeds, BWT Power Inverter heat pumps’ COP is improved by 30 to 40 %. Running at low speeds, the Inverter® compressor and fan(s) are almost noiseless and provide optimal yields. In addition, the service life of the Climexel heat pump compressor, and other components, is extended.
