Frequently asked questions about TWL

One or two heat exchangers?

With one heat exchanger the tank is heated by one heat source. Two heat exchangers allow two heat sources, for example a solar system and a boiler or heat pump.

What is a combination tank?

A combination tank contains a buffer section for heating water and a domestic hot water section. The figure 300/100 gives the total volume and the domestic hot water volume in litres.

Who connects the tank?

Hydraulic connection should be carried out by a specialist company. On request, we arrange mounting, installation and maintenance through our installation partners.
