This boiler works with built-in full pre-mixing gas burner and can be supplied in the versions:
-
Play Entry
: sealed room condensing boiler and forced draft for the production of hot water for heating and instantaneous production of
hot water for domestic use;
The boilers come in the following thermal capacity versions:
- Play Entry Entry 20 : with a thermal capacity of 20 kW (heating) and 24 kW (domestic)
All models are equipped with electronic ignition and ionization-based flame control.
The boilers meet all standards in force in the country of destination, which is indicated on the technical data plate.
The installation in a country other than the specified ones may lead to damage to people, animals and/or objects.
The main technical features of the boiler are the following:
