Rinnai E50CP Condensing Combination Boiler 50K BTU Water Heater Liquid Propane

Rinnai E50CP Condensing Combination Boiler 50K BTU Water Heater Liquid Propane

The Rinnai E50CP Propane, Condensing, Combination Boiler & Water Heater is a wall-mounted, direct vent capable, room sealed, condensing and modulating central heating boiler with an integrated hot water facility. The boiler is provided with a integrated control system. Because an outdoor sensor is connected to the boiler, the boiler works weather dependently. This means that the boiler control measures the outside temperature and flow temperature. With this data the boiler calculates the optimal flow temperature for the installation.

This boiler is designed to heat water for a central heating system and, generate domestic hot water. The boiler is delivered with a burner controller pre-installed. The boiler can be fitted with a modulating outdoor reset control ARV12 (included).
