Wirsbo Under floor heating system, downstairs totally cold :(

[Barry Swerdlow]

My system is split into upstairs and downstairs. The upstairs is working fine

but the downstairs is off.

There is no hot water in any of the pipes in the downstairs system, the pump

is on/warm and there are gurgling noises, but all pipes are cold even under the tap (like a radiator tap)

Any suggestions please?

Not enough info? need photo?

Sounds like you have air in the system

 

[Barry Swerdlow]

Yes it is gurgling a lot, how and where can i bleed the air out?

Did it just stop working or did you have some work done on ANY part of the heating and / or controls?

 

[Barry Swerdlow]

Not had any work done at all, just went off downstairs, didnt notice until we had the cold spell.

Any chance of a pic of the ground floor manifold ?

Right that's great do you have a sealed system (eg filling loop) or an open vented system

3:50 onwards

Many thanks.
Im not sure which system it is but I will look into it.
The video is great I will check the set up and see if I can tackle it myself.

It turned out to not have air in the system.
There was an old electrical automatic zone switch by the boiler which had failed.
