The Esse 350 Greenswitch is an extremely clever insert boiler stove designed to convert your fireplace from something that takes heat out of your house, even when it isn't on, into a modern, efficient thermostatically controlled multifuel boiler stove. It is designed to fit straight into a standard fireplace, as long as you can make a depth of 372mm to accommodate the larger size firebox (it is usually sufficient to simply remove the back firebrick).
The 350 Greenswitch can burn mineral fuel, and will give 11.8 kw to the central heating and domestic hot water and 3.6 kw to the room, running on thermostatically controlled primary air. Turn the 'green switch' to wood burning and it will efficiently burn logs, giving 11.2 kw to the heating and hot water and 3.5 kw to the room. In this mode it will be running on secondary air, controlled by the thermostat, for high efficiency woodburning. By keeping the output to the room low Esse have enabled the 350 Greenswitch to get all the rooms in the house up to a comfortable temperature without overheating the living room. Having a radiator in the room where the stove is enables you to fine tune that balance even more effectively. Esse have maximised the firebox size and it will take logs up to 350 mm long.
We offer an inset fitting frame which is black steel. This sits neatly behind the stove front, and around the stove body, to finish off an installation where the opening is slightly larger than the stove. Total dimensions are 634mm wide by 655mm tall, internal dimensions are 400mm wide x 550mm tall.
