Recommend wood burner with back boiler

Hi,

Can someone please advise on the spec of burner I would need

I am considering purchasing a straford EB16HE 16kw or the EB20HE. 20kw
I have the following rads: Doubles = 2 of 110cm X 60cm , 2 of 110cm X 50cm. Singles = 1 of 160cm X 50cm, 1 of 150cm X 50cm, 1 of 160cm X 60cm, 1 of 130cm X 60cm, 1 of 130cm X 50cm, 1 of 50cm X 60cm, 1 of 80cm X 60cm.

(4 Doubles, 8 singles)

(sorry for all the numbers)

I will also have 2 rads in the room where the burner will be, but i assume i will turn these off when the fire in on. the room is 6mX3,8m

I also would like to heat the domestic water.

Any advise would be great

Hi
It's usually 1kw/single rad. Most companies websites have a calculator that allow you put in room details so you can get the spec size for your stove. Thats what we did and it's fine.
