Thanks all, it seems to be working well now. Will check balancing.
This might be a stupid question, but re the three way valve, which is a honeywell listed as HW and Domestic heating. The HW end goes off into the unvented cylinder (which on research suggests possibly a Y plan setup?). Is the...
I finally got back and turned all the rads off bar the upstairs and shebang, they got hot. Vented a little air that gurgled through. Have started to slowly open a few more and they're staying hot. Will open all again tomorrow and see if th problem is cured or if it's still there
Thanks for...
np!
No, it's vertical, pumping downwards to a 3 way DH/CHW valve, which then runs horizontal about a foot and splits vertical to upstairs rads and vertical to downstairs system I guess (can't trace those pipes through the floors!)
The pump makes very little noise (no bangs or knocks), it...
I have checked for air in the pump (there wasn't any). I've had the pump head off to check it's fine. My boiler does have some kind of pressure or air release thing on the front (i can't remember, will check later).
I dont think it's air - i have water all round all round the system, no...
the pressure gauge is by the expansion tank which is in the same airing cupboard as the pump (and the giant unvented water cyclinder for dhw). I guess you're right, water does come out of the upstairs rads at a decent pressure.
Okay - so this would indicate a problem pumping? I'll shut all...
okay, i turned off all the middle floor rads and it didn't help, but i'll try the all off. Rads bleed fine, i think all the rest are fine (will recheck).
I'm not sure I know how to answer the second question but will see if it makes sense when i'm back in front of it.
As to sediment, not...
Well the pump is in the middle, puming up and down, splits shortly after the 3 way valve. Floors are 2.5 metres high, so it pumps three rads up 2 metres and round, 5 rads on the same floor and 4 downstairs and round 2.5 meters
Hi,
I have a baxi boiler on a sealed system in a three story house. Boiler on ground floor, pump and gubbins on middle floor, rad pipes up and down from middle floor. I recently whipped a radiator off downstairs (remodelled kitchen) by draining the system enough to remove the rad, and...
