It provide a high level of comfort and at the same time provides energy savings for the house owner. This boiler comes with a 6 kW back up electric immersion heater that operates as backup heat in case of emergency. The ash box should be emptied approx. 2-3 times per year maximum, depending on the heat consumption of the house, and holds approx. 45 Litres of ash. The efficiency is very high since we have matched the boiler to the burner. It has a effectively sized hot water coil that guarantees constant hot water.

The Ulma-boiler has an built in three way mixer control valve on the boiler. It is possible to choose between pellets and electric fuel sources. Small light emitting diodes show real power level being used by the immersion heater. The immersion heater makes it possible to retain a minimum temperature without burning pellets if you are away from the house during a longer period. This boiler is equipped as standard with LAMBDASOND which means it automatically measures the gases to maintain a proper burning which results in a better economy. The boiler comes complete with our self cleaning burner TCA 2.
