Wall boiler unit

DESCRIPTION

• The unit consists of 4 boilers of different types widely used in the market.

• The boilers are supported in an aluminium extruded frame.

• The boilers function independently. The heat is dispersed by a unit heater or a heat exchanger (depending on user’s choice).

• The cold water line also connects to a sink fixed on the unit.

• This unit can be connected to the TCF 120 heat radiator in order to test different types of radiators with different kinds of boilers.
