For context, this is an Omakotitalo, with underfloor heating. The heating in the whole house works fine, but it’s noticeable colder in the bedroom. I think it might be the bottom pipes shown in the photo here.
I’m a bit worried with the freezing temps, we might have some issue where the pipes aren’t warm enough and explode or something
Circulation lines one (left) and four (right) are fully open. Second and third appear to have remote thermostats installed. It is possible that the valves could have frozen which is usually resolved by momentarily fully opening the valve, not familiar with the used thermostat so don’t know the correct way to force open/remove them.
What kind of heating do you have in your house? District heating, electrical or a geothermal heat pump or similar? I have a geo pump myself with a similar floor heating system and when i started using it it took a while to set it up so it worked like i wanted it to. Some motors are known to break, Do the pipes with the motors on feel significantly colder than the ones with open valves, if you cant get it to work. Just take off the motors and open the valves manually
I have a Nibe myself, its the same thing but another brand, try checking if the temp dif is big between the inlet and the return line to the pump, if there is a big loss in water temp then you probably have too little flow to the inlet lines (the motors are not opening up enough and it could be that the pump is not running at the recuired capacity, its only so much i can guess myself to with just a couple of pics and descriptions. I’m no expert as well just a regular house owner but if it helps then its all well and good
Looks like rocket science
The upper manifold is the warm water coming from the heatpump, the lower manifold is the return, those white things with the black knob on top are actuators controlled by thermostats, when the knob is out it is open and when it is in it is closed. The pressure should be between 0,5 and 1 bar, it propably has a 1,5 bar safety valve somewhere. The temperature difference between manifolds should be about 3-5 degrees and it seems a bit high on the first picture, this could be becouse of the cyclic function of the heatpump but if it is this high all the time there might be a slight unbalance in the flows. Max’s energy is probably the most experienced company with ground source heat pumps and floor heating in the region but that system is definitely not installed by them
Call a plumber instead of messing with thise knobs yourself.
Also there should be a thermostat in bedrooms and you can test if it works by turning it to 11 and back to zero and seeing if any of those white thingy valve that adjust the temperature move their caps up or down (it takes a while and you can try turning the heat to max setting in every room to test them all and more easier spot the faulty ones)
If there is a faulty one then you need to call an electrician who will fix the white valve thingy.
Upper manifold is feed, bottom is the return, return temperature is always less due to the floor absorbtion. Controllers on the return manifold are controlled via thermostat in the selected rooms /zones,. Water temp controlled via your boiler, or exchanger..
