sizing up c/h system and boiler

[sasik]

I need to get a new system boiler but I need to make sure it is the right size. I have done the heat calculation for my heating system and the total heat output is 31500watts for all the rads (very large system!).
We going to fit a new 260 litre Unvented hot water cylinder. What is the minimum size boiler to support this size system?

Thanks

No but think you should be banned for them comments
You just try to use this forum to ask qualified people how to do jobs you can't do without there information
What you are doing is illegal work
And probably undercutting the people who have to spend money to learn this information

I think you shouldn't be installing if you can't work this out.

For eg. I reccomened you fit a Worcester 15ri

And of you believe that you really need to do some more homework
