Been a long while since I balanced my central heating system, but recent changes (rads changed, removed rads for decorating and new extension) I need to check the system again.
So I have a combination boiler (32kw), 20 rads, the house is 22 years old so not ideally designed for a new combination boiler.
If memory serves me right, I should aim for a 20 C delta on the boiler and rads when the boiler is running at full power, and once it modulates I should aim for a 10 C delta on the rads and boiler.
Is that right?
