Oil burner but now i want a duel system and going to install a back boiler stove. Wanting to know what solid fuel kw stove id need or how would i calculate it myself

My rads below are
800 single
1000 double
1000 single

1600 single

Quickest way of working out your rad heat load is by a rad catalog quoting its output at whatever delta T

However from what you have said what you are proposing is not a DIY job , you could do with talking to a HETAS registered business

I wouldnt dream of installing it myself. I know its a professional job and actually illegal to install one without being registered, I just need to know the exact kw so i can start pricing them online before get someone out.

someone mentioned that 1500 single rad should be 1kw, would this be correct.

Dropbox - Stelrad-Compact-Horizontal-Product-and-Technical-Information.pdf

This will give you the watt outputs of your rads roughly...K1 being a single rad and K2 being a double.

Thank you, however i have looked over that for 10mins and still dont know how to work it out

You need to know if your radiators are single or double, if they are finned on neither panel, one panel, or both. You then need BOTH the height and width of the radiators to be able to get anywhere meaningful.

"P1 also known as Type 10, is a type of radiator with 1 radiator panel and no convection fins.

K1 also known as Type 11, is a type of radiator with 1 radiator panel and 1 set of convection fins.

P+ also known as Type 21, is a type of radiator with 2 radiator panels and 1 set of convection fins.

K2 also known as Type 22, is a type of radiator with 2 radiator panels and 2 sets of convection fins.

K3 also known as Type 33, is a type of radiator with 3 radiator panels and 3 sets of convection fins."

I don't know the designation for a type of radiator with 2 radiator panels and no convector fins!

To be frank though, I don't see what you are hoping to achieve by calculating this yourself. If you supply the spec to a contractor and it doesn't work, the contractor takes no responsibility. If you were DIYing and putting it through Building Control, then I'd understand, but, as it is, you may as well let the professional do the calculations, if s/he is going to do the rest of the work.

Im sure i posted a reply with workings out for your rads given that they where all 600mm high. Its seems to have been deleted?

 

[sammathias]

Given thst all your rads are 600mm high then it would me
12,358watts or 12.5kw +allowance for hot water.

Ive been getting conflicting opinions on the back boiler stoves. Some saying you also need oil if you want the rads pumping hot for a house that size so im kind of in 2 minds to get one now. I have a few k to spend and was hoping to install one that would deal with most my heating needs during winter but like i said, im in 2 minds to get one now. Even someone we know installed a 25k stove and its not heating all the rads as she hoped for. Think theres one bedroom that doesnt even get heat to it
