Questions about underfloor heating via pompe a chaleur

[mogs]

We have this system and from what I understand the pump sucks in the air to heat the water which then runs into a system of pipes and then heats the water which warms our underfloor heating.

Each room is marked on the network of pipes on the wall with taps which turn the valve pressure from 0 - 5, 5 being to warm the most.   We can also control the temperature by changing the main thermostatic which goes up to a maximum of 30 deg.

As we have a wood burner in our main room we have turned off all the valves to 0 just for the lounge and consequently you can feel the floor isn't warm as it is in other areas.

However in the bedrooms we would like them to be warmer so have tried turning the valves to 5 but for some reason the taps which control the valves seem to be stuck at around 3-4 pressure, almost as if the tread on the tap has busted.

Are there any experts out there who know about this type of heating to let me know if the temperature of the floors should be consistent, as in the main bedroom it feels much cooler.

Not knowing how you are set up its difficult to comment but it sounds as though you are talking about fiddling with the valves on the manifolds?

If this be the case you are  managing flow rather than temperature..any change in temp will be as a consequence of restricting flow.

You want to prioritise the bedrooms so will need to try to figure which pipework gets hot first at the manifolds then wind these back until you have the system favouring the most 'difficult' circuits. the manifolds will have flows and returns and ytou will be able to figure this from the markings or from which gets hot first (worth popping some coloured tape on the pipe necks?)

A clip on temp guage can be handy for measuring heat on the returns. worth looking at your programmer are you sure you aren't 'zoned' there too or have a room or system stat that may be on the blink so not calling for heat etc.
