heating system boiler suitability

[alandublin]

Hi

I have a white star combi boiler 29kw 100,360btu

I am building an extension to my house and have a combination of single and double rads as follows

500mm single rads x 6

800mm double rad x 1

1000mm single x2

1000mm double x2

1200mm double x4

1200mm single x2

2 showers (pump showers) to bathroom



My question is the boiler big enough to run the system

Thanks

Alan

You can use the Stelrad Elite catalogue to estimate the output (in Watts) of your existing radiators.

Add them all together and if the total is less than your boiler's maximum output, you'll be OK.

Just noticed - you mentioned pumped showers, but say you have a combi?

Am I missing something here (like a hot water cylinder for example) ?
