• Builder threw a curve ball; do we want wet or dry underfloor heating in the extension?

    I’ve always assumed wet as it’s more efficient, but with the cost of gas…

    We’re getting a new boiler, new aluminium rads in the existing rooms. I guess if a heat pump ever materialises wet underfloor is better in the long term. I’m thinking out loud. Input welcome.

  • As long as gas prices are cheaper than electricity, wet underfloor should be better and cheaper in the long run.
    As floor turns into a giant screed radiator and runs at lower temp, should be more efficient, but not as reactive in temp changes as electric.

  • Wet

    Unless it’s bathroom sized?

  • Wet, fed from an air source heat pump.

  • We’re going for wet underfloor bc radiators are a pita
