Just get the next layer to be as per saveasteading's post!

That will be fine!

Could you paint the underside in a bathroom spec/colour matched paint? Prob need to prime it first!

Honestly, just install Air Con! We did and I love it. Extra burst of heat in the winter should it be required, and then instant full cooling for the summer heat waves. Also ensure you have it for the home office /study! For the sake of a few grand... No brainier.

That's be closer to a £50k budget in my mind to take it all down and rebuild it. Depending on where in the country you are on value for money. Central London yes, up north probably not! I'd probably look to reroof, broadly similar, look to maybe dig down and retrofit UFH! Overboard with insulated pb....

Have you got a close up of the label? The tin looks pretty ropey. If you intend to park your car in the garage, I would buy some proper decent stuff. Once you've put paint down, if it does lift you're in a world of headaches!!

Does QAD have a tech support line? They usually do! Is it water based? I would expect to thin the first coat down a bit. I am using a 2 pack epoxy paint for our garage when I get it tidied up. Never had an issue of warm tyres peeling it up like normal single pack paint.

2 story foundations on a 3 story house maybe?

We have a lot of driveway & surrounding paths to get done, around 220sqm from my estimates. We have a white render & black window, door etc style, so would like a nice black/charcoal block paving that won't fade to grey. Very contemporary style to the house so looking for 'modern' looking.. Just if anyone could recommend where to start with choosing the right block paving? Any resources people used to help them decide on their own? Cheers,

Interesting read! Please keep us updated with the performance!

Would recommend wrapping it in duct tape at regular intervals if a tight fit!

Heating challenges aside, it's a quirky & attractive house! I see the appeal of it, even if an extra £100 a month to run. Start with the easy stuff, 400mm loft insulation minimum. Secondary glazing, even if magnets and acrylic/perspex sheets. Draft proof and cheap thick rugs (eBay has loads) on the ground floor. Any options to fit a wood burner? External insulation, or Insulated plasterboard overboarding on the inside!

Would love to see pics of this, bigger brother to ours by the sound of it!!

We had a sunflex sliding/floating corner fitted, 2.4 x 8m for about £14k fitted a year ago, double glazed but laminated etc. Very happy with the doors, but the fitters were average.

The telegraph is toxic these days, their anti-heat pump and anti-EV bias obsession is ridiculous!

Thank for all the comments here, our setup is decidedly awkward & hard work to manage! ASHP feeding 2 x UFH Manifolds with no blending valve but we are over zoned thoughout (lesson learnt here). Every room having its own stat - 22 of them throughout the house. Due to a c290sqm bungalow and 2 x mono pitch roof we also see very different temperatures throughout the house because of very 'odd' rooms...small floors & high ceilings etc etc This means we have 3 bedrooms which are relatively small floor space with very high ceilings - because they each have a mezzanine & staircase in for sleeping 'up stairs'. Floor being carpeted means these rooms are always 15% colder then the rest of the house based on the small floor vs volume of air inside. Blending valves do not make enough of a difference to balance these rooms vs rest of the house - probably due to our manifold being 11 zones on one pump & flow rates being bottle necked. A night time setup of 2 degrees & operation 24/7 would have these 2 rooms short cycling the ASHP all night & rest of the rooms only needing 1 top up a night. That being said on average nights - mid single figures no real issue. 2 x 4 hour chunks sitting in the Cosy periods is enough to keep all rooms at 20 degrees and the 'cold bedrooms' around 18 degrees during daytime and a degree or two lost over night. On very cold nights we need to run for c10 hours to achieve the above, then see temps flow as you'd expect. All of this is done with a flow rate of 28-32 degrees, hence debating flat lining the flow rate at 37 degrees during Dec/jan to keep us warm during the day & maximising cosy cheap rate of 16p and dumping more 'raw heat' into the slab to coast through the real cold snaps. I have lifted up the Weather comp from 2 degrees to 4 degrees (i think).....would a compromise be to lift it up to say 6 degrees? I presume this would lift the flow rate up a few more degrees on the low end, but still have a sort of weather comp to help efficiencies on milder days?

We run a Samsung Gen6 ASHP and despite having a 'well' insulated house (very good vs average new build, 'good' vs BuildHub standards) it is still a challenge to really warm up - caused by it being a sprawling bungalow with very very high ceilings (3.5 to 4.5m throughout) and carpeted floors. It was fine during the last cold snap we had (3-4 days of -3 temps) but we needed to run the ASHP all day to keep around 20 degrees, and at night it froze up so we turned it off and only ran it al day. With our current setup we run all zones together, to maximise the 2 x cheap periods with Octopus Cosy. Right now we have 50% of the ASHP in the cheap period and 50% of the usage during the 'normal' period. One frustration I do have, is that for the majority of the heating times, our flow rate is around 30degs which means it takes ages to warm up during cheap & normal rate periods...but oes eventually get there with a 'high' flow rate temp of low mid 30s. I am weighing up for 'winter' periods disabling Weather Comp, setting the flow temp at a flat 37 degrees (so still 'ok' efficiency wise) and using this to get more heat out of the cheap periods, and reduce our usage of non cheap periods. Even if we take a 20% hit on efficiency going from a weather comp'd 30 degs to a 37 degs flat temp.... then the 30% cheaper rate elec still means we are quids in, and have a quicker warm'd up house! Just wanted to test this logic with the team! Cheers,

Wonder if you could use porcelain tiles?? They come out of a kiln... Though IANAL

We did have mains gas as an option, and I'm only 70% sure ASHP was indeed the best short term solution (I don't think we will get the gov grant for our installation) . Long term I'm very confident it will be, as electric & gas prices are disconnected/swung as more renewables come online, but having watched it during a week of sub zero temps I accept there's more compromise then I was expecting. Hence always warning people to really REALLY be sure ASHP is the right thing to switch to, and to never rip out a working gas system 'because ashp is in the news and everyone is discussing it'.

I own a ASHP in a modern new build house and I'm happy enough with it... But your application makes no sense. Huge up front investment, more so borrowing the money, for a payback period you'll never see. Any sustainabilie benefits are lost binning a perfectly good gas boiler and radiators for a new toy. Also assuming your small garden (nevause new build?), where will it go? How will you route the pipes into your property? How will you route power cables to the outside unit? They are noiser then I imagined, which in a new build small house you will likely hear, as will your neighbours. Really really spend your money elsewhere, solar panels and a hot water pv booster for example!!

Not a dissimilar position to what I found myself in last week! Let the floor get too cold experimenting in the cold weather and there wasn't the warmth to enable the defrost cycles to run effectively vs getting raw warmth into the slab! Lots of energy for little true warm up of the house We only have a 60mm slab so can't coast as long through sub zero average temps.

Aa said, I've seen worse and you'd be amazed at what plumbers will do butchering their way through these, only to then hide it below some ply and tiles!! Sister joists, glued and screwed well and forget about it!

Found it! it's the MVHR, turned them both off at the mains and all looks to be be resolved after 14 hours. After several hours of research found someone on Facebook who had similar and discussed it bring an anti frost thing the MVHR was doing. Having looked at the MVHR manual (vent axia sentinel) it does say below 0 degrees it does activate frost protection. For now, I'm just happy to have found the culprit.

Could at lest expanding foam over the pipe? Do insulate the recirculation pipe at least!!

Another room.... Over the course of 24 hours later
