Got a wet based underfloor heating system that has been installed as part of the building work he did for me. The guy who installed it for me is on holiday for 2 weeks and I was wondering if the problem is a simple one to solve?
The problem is as follows:
The thermostats do not seem to be regulating the heat in any of the rooms which I'm confused by.
The thermostats have been porgrammed correctly in each room and they have a max min and max temp setting. However, the room's are hotter than the max temp set and the thermostats do not seem to regulate the heat from the UFH system to reduce the room temp. When I took a look at the manifold, the flow rates are high even when the UFH system has heated the room above the 21 degrees (the max temp i have set.) and the bolier keeps firing up to provide the heat which will be costing me an arm and a leg. I assume that once the target temp is met the flow rates should be at 0 till the room temp decreases and the UFH needs to provide more heat to the pipes to bring the room temp back up (the house is well insulated also) to the target temp set?
You are supposed to be able override the programmable function by using the up and down keys on the digital thermostat (model HA208) to inc or decrease the room temp, but that does not seem to work either. The UFH pipes are laid in screed (on a concrete floor in the kitchen (on sandstone tiles and between timber joists in all the other rooms which use engineered timber flooring). At the moment the only way I can regulate the heat is to turn the whole system off and then turn back on when we need a bit more heat. This defeats the purpose of having a digital thermostat so I can control when the heating comes on and off throught the day.
