Boiler room for connection to heat pump and collectors

Boiler room for connection to heat pump and collectors

Sigma’s new boilers are designed for connection to heat pumps and collectors, in case collectors are also installed, so that the heat pump is not overloaded during the summer months. Our range, also in this product, currently ranges from 200L up to 500L.
