Hi all, I have an issue with my UFH that I hope you can help with.
We have UFH but have never been 100% sure that it works as it should: the lounge/kitchen (one room) has been fine, but the bedrooms have always been a bit chilly. I've put this down to them being carpeted and it taking longer for the heat to transfer through.
But now we have a baby on the way and really need to get to the bottom of it, so I've been trying to adjust the flow valves to balance the rooms better thinking that this may solve the issue. However, when I loosen/tighten the flow valves only the one for the kitchen rises and falls to show more/less flow to that zone. Can anyone suggest what the issue may be? And is this tied to our flat being cold?
As an example, the heating was on all day yesterday and set at around 18 degrees in the bedroom. When we went to go to bed the thermometer was only reading 14 degrees.
Some additional info:
- The actuators all seem to work - the pins on top rise and fall in line with the thermostats in each room.
- I can tell that water is flowing to zones, even if the flow valve indicator is right at the top (0 l/s) because the pipes underneath feel hot. Likewise, when I close them all the way the pipes feel cold.
- The pump is brand new and was installed by a plumber due to the old one expiring.
Thanks in advance! Would appreciate any advice you can give me.
Here's what the manifold looks like:
