Calculate expansion of central heating water

Paddy01 · 23 Oct 2010

I have a sealed central heating system.

I have estimated that my system contains about 60 litres of water. (rounded up)

I want to know what size expansion vessel should be fitted?

12 ltr should be fine.

if you allow 4% expansion you'll be alright.
