Electric Boiler - Small garden house

Irishguy

HI All

Building a little Granny Annex in my back garden.  Nothing very big.  Open plan kitchen/living room, bedroom with ensuite.  The build is a total turn key.  I am concerned with the hot/water heating system.  It is a Potterton Gold 6kW.

Since electric is my only option, is this a good model or is there another model suggestion?

Thanks,
Mickey

Unfortunately, ANY electric boiler will incur the most expensive running costs possible.  You couldn't have chosen a worse solution.

If it isn't too late, perhaps a small Air Source Heat pump setup would be a better solution if you have space for a hot water storage tank.

If it has to be wet electric heating and there's a good reason why you can't fit a heat pump, that is as good a boiler as any.

A heat pump will cost roughly 1/3 as much to run. Reed_Richards fitted one a year ago (a much bigger one than you'll need) and has a thread about it here.

If it's not too late to move away from wet heating, an air-air heat pump might be a better option; danrv has renctly fitted one and has a thread about it here.

Possibly too late, but I would be most concerned with the energy use - how passive is the house designed to be?  The cheapest heating/cooling is the sort not lost to the outdoors.
