So my ufh has been working well but has been struggling a litte during this last cold snap. The combi boiler is set at a flow temp of 55*c the manifold is set to supply 45*c and the floor probes act as a limiter with a max floor temp of 27*c. Centers were 150mm sitting on 200mm of celotex.The...

So our flow screed was finally pumped in on Friday, I've got someone coming to sand it later this week. I've still got upstands, slip layer and dpm which are coming above the screed level (on purpose) which now need cutting flush. Will this need to be done prior to the sanding? and secondly can...

So I've finished the pir insulation layers for my new solid floors. I've filled and foamed any gaps between joins between the pir sheets and against the walls. But now wondering if I should tape all joins before I put down my 500 gauge sheet to prevent the flow screed getting under? I will be...

So the finished insulation floor height in my kitchen is about 12mm lower than the hallway due to an issue with the concrete depth being off to what was specified. The wet ufh loops are going to all rooms downstairs and for the kitchen loop it will need to cross this 12mm height difference, the...

So i've got my plans back from Wunda and about to start laying in the next week, however I need to install a floor sensor to measure and restrict maximum floor temp to preserve flooring correctly. This is what I'd be installing https://heatmisershop.co.uk/remote-sensor-probe-3m/ Now the...

So we've bought a house, but one of the bedroom window top openers won't pull in as it looks like this piece of plastic has worn through, which I'm assuming helps pull the window back in. Can someone tell me what this is called and if I can get a replacement? If not i guess i might be able to do...

So I'm having a 12cm slab poured next week ready for me to continue building up the next layers of PIR insulation, installing and pressure testing ufh and then have screed pumped in. How long will I need to leave the slab until I can start on the next steps do you think? I.e. dropping 150mm pir...

So I'm about to order a routed chipboard structural flooring from Omnie (22mm) which will replace my current floor boards. The joists on this suspended timber floor (downstairs) are 100mm deep and so I've purchased some PIR insulation and was planning on taping all joins and over the joists so...

I was planning on running a 25mm PIR upstand first around the room and then my 150mm insulation to effectivley hold it in place. I'm then planning on running over some spare 1200g DPM to act as a vapour barrier and then will use Omnie screed plate to hold piping in place. What I'm confused about...

So I've dug out my kitchen floor and now need to reinstate an air duct under it back to the suspended floor on the other side. There was previously a pipe across this solid floor to an airbrick on the external wall. Now I've dropped the floor level so the plan is to use one of these telescopic...

I'm hoping to dig out my solid kitchen floor at the weekend to retrofit insulation and wet ufh. In terms of depths the current guidance seems to be https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/1081194/solid-floor-insulation-best-practice.pdf...

We're thinking about having our windows replaced in the next year, and mentioned the sills we have look dated and if the local window company would be able to sort and the chap suggested it's not something they would do and it needs a builder. I'm assuming that he means the tiles (if that's what...

So I'm about to dig out my solid kitchen floor which has an air duct/pipe going under it and comes out on the external kitchen wall. This is because there is some suspended flooring in the property, and there is also the same duct/airbrick at the front of the property. I've dug out a small core...

So I'm trying to retrofit wet ufh into my 1969 house, 70% of the floor is suspended and so I'll be insulating that and doing a structural routed board for the piping, the kitchen is however solid, 12cm concrete over a dpm and then hardcore. There is an airbrick on the external wall of the...

So after lifting floor boards I've found that my joists for suspended floor (ground floor) are 100mm deep. I'm planning to lay wet UFH using a structural board later on, so want to maximise the depth of PIR into the gap between joists. Building control have already been around and are happy with...

So the current plan is to have a 40kw 8000 with two zone valves, one to cover the downstairs wet underfloor heating which will have room thermostats and call the boiler via the wiring center. The second zone valve for upstairs radiators as a single zone with one thermostat. I'd thought about...

So I've asked a roofer who is about to DPM the flat roof of our dormer to also add insulation to form a warm roof as this was called out as an issue in the survey so whilst rennovating a little it would be good to tackle. That then leaves the cheeks and roof underside as per the following...
