Thermia Diplomat TWS is a very highly regarded heat pump. The reason is that it is extremely efficient and reliable.

Our specially developed and patent pending TWS technology gives both more and hotter water considerably faster than old technology. It has an extra large hot water tank. The time it takes to refill the hot water tank after peak consumption has more than halved.

In addition, it can produce – if you require it – higher temperatures for the heating system.

Thermia Diplomat TWS is so effective that the heating cost in a house can be reduced by more than 75 percent.

It also has Thermia’s specially developed scroll compressor. This makes it a really efficient heat pump and contributes to operational reliability and quiet running.

Thermia Diplomat TWS is very user friendly and easy to maintain. It is available in five outputs and has an integrated electrical heating element with three power stages (3, 6 and 9 kW) for additional heating when it is unusually cold outdoors.
