The Murelle Revolution 30 is the first completely integrated boiler and heat pump in a single cased product. Using an ErP A++ 30 kW Murelle boiler and sealed 4kW output heat pump, the Murelle Revolution 30 is a single unit which is installed inside and hung on the wall like a conventional boiler. The Murelle Revolution 30 can be installed by any registered Gas Safe engineer in a single installation, without the need for an additional F-gas-registered installer to be present and provides heat and hot water, achieving an average seasonal heating performance of 134%, granting A++ energy efficiency.
The boiler and heat pump work in tandem with the heat pump operating first. When the external temperature is higher than the minimum set value of -7°C the heat pump and the boiler will be activated in quick succession and when the set point is reached, the boiler will adjust power until the heat requirement is achieved. If the external temperature is higher than 7°C only the heat pump operates - the boiler is only activated when the desired temperature is not achieved by the heat pump on its own, ensuring maximum energy efficiency.
