Hi all,
New to this site and looking for some advice.
We built our house 11 years ago and had underfloor heating installed upstairs and down.
I have been more than happy with the system in general, although it was sore on oil for the first year or two until the house was fully dried out.
Our system is zoned with a manifold on each floor and each room in the house has a stat. Our system runs off a standard oil boiler. I have noticed over the last couple of months that some of the rooms are hard to heat so I finally got around to checking the system today. My initial thoughts were that I had a couple of faulty actuators but have taken them off and they are opening and closing as they should. There is plenty of hot water coming in and 4 out of the 6 rooms on the manifold are heating perfectly. On the two rooms that aren't heating, the outflow pipe to the room is hot when it is calling for heat but the return pipe is cold. On the rooms that are working, both pipes are hot with the return pipe being slightly cooler, as they should be. There is two bleed valves on top of the manifold but there is no sign of air from either of them.
Is is possible that there is a blockage within the loop in these rooms? Is is a big job to flush out an under floor system?
Any help or advice would be much appreciated.
Thanks and Regards,
Conor
