    No, as I am a long way off fitting a new heating system.

    Pipes are not insulated.

    That is power, heat is another word for energy. We had skirting radiators when I was a kid (days of town gas). Never remember the house being cold. The ones we had were quite boxy and in a dark grey. Behind the box was a copper pipe with fins on them. I would consider some of the more modern designs ones as I cannot realistically fit UFH and I hate exposed pipework.

    Sort the building out, then you only need a smaller thermal load.

    Some Charts showing variation in UK mean, min and max temperatures over the years. And a bonus one, hours sunshine

    With virtually no air movement at all.

    We don't get excessively high air temperatures and we normally have a breeze as well. Different up in the home counties and in more built up areas. I seem to remember looking at the temperature difference between Penzance and Newcastle, only about 1°C colder up on the East Coast, on average. But the temperature range was was much bigger than Penzance. And it is not as windy. Sun is higher in the sky down here as well, this can, depending on house orientation and design, reduce passive gain.

    Have you thought about how you will bond it, and if there is any PVC nearby?

    But the wall area is a lot smaller than the floor area, and convection currents will limit the temperature. That is only changing the temperature, not the floor insulation. Though as you say, you only have the building regs when the house was built to go on. Trouble is that you also run the risk of lower CoP at other times. So under sizing is a high risk policy.

    You could try testing it from the temp difference between the flow and return, and at what rate the room heat up. I that a temperature difference of 12°C? Should it not be the slab temperature minus the ground temperature?
  11. SteamyTea
    Is that latent or sensible?
  12. SteamyTea
    How much are you loosing from the UFH to the ground? Bigger ∆T, large area and possibly poor insulation levels.
  13. SteamyTea
    Welcome. If you internally insulate you can, at the same time, deal with airtightness and relocate pipes and wires. Messy and involved planning, but gives a better job probably.

    And voltage regulators.

    They won't be in his/hers favour.

    Vortex generators are not a new idea, they make versions that go into flowing water. A mate of mine worked in the marine renewable energy sector. His job was to computer model the energy output. He left that job because he was fed up with projects that would never work, designed by dreamers.

    We stopped taking AmEx because of the high transaction charges and the delays in receiving payment. AmEx did not take us off the Small Shops register, which upset a few customers who think it is their right that we, a small business, should pay for their rewards. Can usually tell when someone is going to use AmEx as they hold the card face down as they present it to the NFR.

    This sort of nonsense relies on people's lack of understanding of physics. Tell the conspiracy theorists that it works at the same frequency as 5G, that should be a laugh.

    I am always amazed that people are reluctant to do this. It is probably the cheapest way to test your heat load. Could even out energy meters on them, and a cheap data logger. Tempted to design a box of tricks to do just this.

    I had some cracked render, the water came in a good 2 metres from the damage. I also had the loft insulation move (as have half my neighbours) a few inches in a storm. Was enough to just cover over the soffit vents, then each time a hoolie came in, water got soaked up into it, then into the ceiling below.

    Lower than what?

    I often feel that some Architects are good at sales, then the hard work starts. I suspect that you owe/already paid then several thousands. Have they done and real onsite decision making, or is it the relatively easy office based stuff. It is easy to redraw a line, bot so easy to remove a foundation and relocate it. My experience is that sales people are all to willing to walk away from the job once they have sold it as easy.

    I think you are. kW is the power you need, kWh (or more likely MWh over the year) is the energy. Thank of energy, the kWh, as how much fuel is in your car, power (the kW) is how much you press the accelerator.
  24. SteamyTea
    Neither did Wendy. Anyone seen her since.
  25. SteamyTea
    PU quite often used water as part of the curing process.
