    Since you already have underground ducts buries, I would run some cable in to the cavity. Make sure you have a good sketches and photos of what you have installed. A tape measure in the photos will help later to find them.

    I use this one - https://joint-research-centre.ec.europa.eu/pvgis-photovoltaic-geographical-information-system_en

    I do hope that you don't ask all 22 companies to quote, as that mean that the other 21 will have to pass that cost onto other customers. Accurate quotes take time and cost which someone has to pay. That said I don't (and hope) that you are just buying on price only. Enjoy your build

    Depending on your soil conditions I would look at an insulated slab rather than beam and block.

    Rainfuel

    Adrian Walker commented on Marvin's blog entry in A Rainfuel project

    I agree, that not a lot of energy 🙂

    The problem with opening windows (if the house is ~airtight you will need to open at least 2) is that that heat will escape. UPS is the best and cheapest solution and could power MVHR and broadband.

    Rainfuel

    Adrian Walker commented on Marvin's blog entry in A Rainfuel project

    That is the rain fall for a whole year. I don't think it's a goer, not much energy. If you want to use water as a battery, pressure rather than volume is better - that's what the Victorian did.

    Rainfuel

    Adrian Walker commented on Marvin's blog entry in A Rainfuel project

    It's easy to a create a voltage, but without any current there is no power. I suspect that there is more energy in storing rain water in a roof tank and using its potential energy to drive a water motor. A typical roof will have ~70m3 of water. 70000 kg x 10 m/s² x 5 m (building height) = 3.5 Megajoules

    This is a good example from Robert Murray-Smith

    Smart EV chargers detect the max current and will throttle back since thy will be the biggest load and and can wait - dinner can't

    Thank you.

    Are you an authorised installer for Sunamp and what do you charge for an install?

    Welcome to BuildHub. Are you building in Wiltshire?

    I had a similar problem and found that if i disabled Wireless Multimedia Extensions in my router the problem went away. YMMV, but good luck

    Unless you are part of a way-leaves agreement, then it going to be to expensive to move (£1,000,000+). That said the house prices would have reflected that.

    Andrew at VAT431 is an excellent resource. Good value for money

    Just because you had a bad experience, you should let others do their research, etc.

    If you're considering at Isotex, then I would have a look at the Velox ICF system, which also has flooring.

    If you are buying DS18B20 sensors make sure they are the real thing, not copies and work properly. They all have a unique serial number. Someone on here bought a load and calibrated them, I think 3 out of 20 failed.

    The UFH pipes need to be less than 100mm down to work effectively.

    You needs to get yourself a CO2 sensor/logger. This is where I get mine from https://www.gasdetectorsdirect.com/products/air-quality-guardian-aqg

    Norfolk Brick have loads

    I would put CO2 monitoring on your list (near the top IMHO). This will tell/confirm that you have a healthy environment.
