  1. Not seen expressed like that, and I am tired after work. W [watt] can be expressed as J.s-1 [joule per second]. J [joule] can be expressed as kg.m2.s-2 [kilogram times, metre squared, times second raised to the power minus 2] I think you probably need to know the specific heat capacity of the floor material i.e. concrete ~0.8 J.kg-1.K-1, then convert it to a volumetric heat capacity with the material density i.e. concrete 2700 kg.m-3. Then cancel out what you can. I tried to rearrange it all, but too tired. All seems a bit complicated this late at night, but luckily we have a mathematician professor on here, so maybe @Garald will be along to finish off the sums. It is starting to look very similar to the thermal effusively, or thermal inertia units. W.s0.5.m-2.K-1 https://en.wikipedia.org/wiki/Thermal_effusivity
  2. That is what we would do, but others, in the future...
  3. After several year, can you safely stand a small scaffold tower, or ladder on EPDM?
  4. Is can, but these new PU resins are marvels of chemistry and can be applied in the wet. I want to play with them, but missed the guy when he did the roof.
  5. You will pay a premium. Say you live in Mount Hawk, they are all unemployables there.
  6. GRP properly done will last 40 years. We have just had our old corrugated asbestos roof repaired with a polyurethane, not rained yet so cannot comment on it at all.
  7. Mine did in January, but you probably still pay less though OVO than I do with EDF. You cannot have it all ways, delayed increases and instant decreases, how we got in this mess to start with.
  8. Trouble is, the scale of the problems means we all have to chip in. I would be happier if the Government increased basic income tax by 2p. I am sure I could cope with that, and anyone that earns more than me and @ProDave, could stop buying a coffee at 3 quid a cup, or knock a minute of the showering time. Really, 2p on basic rate is pretty small considering we have a £12k+ tax free allowance (thankfully frozen). I do think it is unfair that we each household has to bail out some bad energy companies. Not as if I bailed out Bon Marché, whose shops I had never entered, every time I buy some new knickers from Poundland.
  9. Solar, though not sure of PV or ST. I assumed it was for drawing convivence. Would, adding a small buffer to the solar side help even out the temperature to a usable level? Solar tends to be a variable source, where as, and ASHP, is pretty stable.
  10. It is added to the meter rental, which has doubled in most cases. Rather pisses me off that I am paying to bail out companies that attracted skinflints that wanted to save a few quid a year by buying energy of a company that had an unviable business plan. If a company offers a better deal than the major players in the market i.e. British Gas, EDF, then you have to ask where they are making the savings.
  11. If you think of it as electronics, 2 diodes in parallel is an OR gate I think.
  12. Good stuff. Other countries have been doing it for decades.
  13. Quite possibly, but there is exchange rate changes. And the government has bailed out each bill payer between £400 and £550 pound. And we have a price cap which is adjust every 3 months now I think, half the time of 6 months ago. And the government has bailed out Bulb Energy by £6.5bn, that is about £260 extra on our bills.
  14. I have never really understood what that word means with regards to Photoshop. What does it mean?
  15. Because we have a price cap. It will be reducing in April I think. Volatile pricing, which is what is being trialled at the moment is going to be horrendous for most people.
  16. Did wonder if the house insurers were the ones that actually paid. Would probably cost only a few quid on glyphosate to get rid of it. But both sides have had Thier 15 minutes of fame, and the new home owner has promoted his business, not that I would risk buying any of his furniture. Might end up in court. Did we not have someone on here complaint about Thier neighbour restricting access, and the person who lived next door complaint about the neighbours extension. Or did I dream that.
  17. Don't let Jacob Rees-Mogg here that, he will lower the standards. Was told that he thinks childhood illnesses like whooping cough and mumps need to come back to give the country some backbone.
  18. And you are less like to be naked in the kitchen. Imagine family members standing around your naked body on the bathroom floor as they wait for the police and ambulance to turn up. Two to four hours of sniggering.
  19. Wasn't it you that wanted to put a camera down your lavatory bowl to activate the only fan. DoorBird is already water proof.
  20. Not when you look at the tree shadow on the scabby cladding, but the sun behind the building. Like most wet dreams, they soon age.
  21. More a case of one of the things that affects total system efficiency. Drop the flow temperature too much and the CoP collapses as there is no usable power leaving the Carnot Cycle.
  22. @worriedexpat Where in the SW you building, and is the Architect local to it? West Country is now a stupidly large area, seen Oxford called The West Country, and Swindon has been for years. I think Bristol is in the SE, but then it is 200 miles away.
  23. On a school camping trip I had to share my tent with tins of Spam. As it was 1976, most of it got a second cooking. Never eaten it since, so 47 years Spam free.
  24. Welcome Or it is just sized, or set up, incorrectly. A lot more information would be needed to find out what is possible. There are loads of topics on here about heat pumps not working right, it is nearly always a commissioning problem. They are not run like a gas boiler. Have a hunt around on here and see if there is a similar problem for a similar size and age house. Then when you see the answer is to insulate and improve airtightness, you will know what to get on with.
  25. One swallow does not a summer make.
