Hydraulic interface unit between solid fuel boiler and gas boiler DESCRIPTION ECOKAM units are used in combined gas boiler and solid fuel boiler systems (fireplaces, heating stoves, hydro-stoves, wood and/or pellet boilers) with open or closed tanks. Thanks to the hydraulic separation of the circuits, the powers of the two generators can be kept separated, as per ISPESL R collection.

ANTI-CONDENSATION SYSTEM (optional) • add “A” at the bottom of the code - except Ecokam S The ECOKAM interface units can be fitted with an integrated anti-condensation device. It consists of an adjustable thermostat located on the return line of the solid fuel boiler. Depending on the set temperature, the system pump will only start the heat exchange with the system when the set temperature is reached, thus avoiding any cold return that could cause condensation on the boiler exchanger. INSTALLATION WARNINGS It is advisable to use flexible hydraulic connections in order to compensate for any...
