I forgot to add, your and all Bi TRVs can be fitter in any position either side, FLOW side is most efficient, the arrow ones should be fitter as I said.👌
You should do a video on what to do, on underfloor heating, and the hot water goes from boiler to underfloor heating, and just stops at the water pump/mixer on first stage of the manifold for the underfloor heating. For some reason, we have 50c water going to that point, and at the water pump mixer on the first step of manifold, it just puts out 20c water into the underfloor heating zones in our heating. Have you come across that problem, and can you do a video on what to do with it, is it the mixer valve, pump or some sludge in underfloor heating or what? 50c water will go from boiler to manifold, and then at mixer stage comes out at 20c, and all that goes into underfloor heating is therefore 20c water. If you had that problem how as a plumber would you fix it, our upstairs normal radiators, and downstairs underfloor heating are in different zones, and are on separate loops. The pump on the manifold is working, and pumping, but it just pumps out 20c water, the 50c water coming from boiler just stops, and how ever the mixer is working, it just remixes i assume the cold returning water back in with the hot water, and therefore, water does not go over the 20c in the system of underfloor heating.
Hi Andy, thanks for asking, I did UFH in the 1980 /90's but lack of demand I stoped to concentrate on Combies. Depending when installed you could have a claim against the installer via the Consumer Act 2015 (not fit for purpose and lasting for a reasonable time) 6 years to claim, get legal advice. You could also go to the manufacturer and ask for help to solve this problem. Hope that helps. take care, George 🤩👍 PS. I still love UFH it's the best way much better than rads 100% efficiency cheap to run.🥰
I'm pretty sure that my boiler feeds a manifold (located under the upstairs floorboards), which then distributes to each rad via microbore pipework. So will the nearest & furthest away rule still apply? I have locksheild valves on one end and trvs (no arrows) on the other (except 2x towel rails). I know by touching the feed & return that some of the trvs are not on the feed side. However, no arrows on the trvs means that's OK? I have 8 rads & 2 towel rails, so I divide the system into 4 and follow your system? Have I got that correct?
Hi Alan, thanks for asking, yes correct divide by 4 or 3 which is best for the system. All TRVs without an arrow are bi directional very good, but they are mounted differently. If the TRV side warms up the sensor side it MUST be VERTICAL, if fitted on the colder RETURN it MUST be HORIZONTAL a mistake many installers do. See my video on the Danfoss balancing TRV. The best is always on the FLOW side because it responds sooner thus saves more money. Hope the helps, George 🤩👍
Thank you Mr Combi Sales 🙏
My pleasure, 🤩

I think I skipped a few steps. Ended up with my cat in the dryer :(
Painfull🤔
