Rinnai E75CN E Series Condensing Combination Boiler 75K BTU Water Heater Natural Gas

The Rinnai E75C Condensing Combination Natural Gas 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).
