Central Heating pump speed

[garrymum]

Is there a general rule for what speed setting your pump is set to? Currently, mine is on full (3). It's a conventional system with water cylinder and CH F&E tank in the loft. There are 13 radiators in total, 2 of which are double, others are single.

Thanks

Hi, thanks for the reply. I have 13 rads, what is an "average house"?
I have set the pump to position two. What symptoms should I look out for if the pump is struggling on this speed setting?

Thanks

I have set the pump to position two. What symptoms should I look out for if the pump is struggling on this speed setting?

1. Is the boiler overheating, i.e temperature rises very quickly and then the boiler cuts out?

If "yes". The pump is not moving the water fast enough. Set it to 3

2. Are all radiators heating up OK.

If "no", the pump pressure is too low. Set it to 3.


Has the system been balanced? If not read How to Balance a CH System
