I've got an extension!

Yes, my house is now bigger - so more rads. I've read that the normal max rads for a pump is 12 but I will have 13, including towel rails. The rooms are quite small so there are some small rads in that - all fed by 22mm branching to 15mm from an open vented system.

So, will my standard circulating pump be enough?

Thanks for any replies

Thanks for that, how many rads are you running? more than 12?

i have 14 rads and runs fine off a combi, not sure which pump but if 22 and 15 should be ok
