Question about underfloor heating.

    We have underfloor heating with climate controls in each room. Set the climate control to a temperature, the underfloor heating will kick in until it reaches that temperature, then clicks off. Kicks in again when the temp drops... I'm sure you all know what I mean. Am I right in thinking that we should leave the heating on all the time and let the controls do the work of turning on and off the heat in each room? If that's right, is the central heating not burning all the time and costing a fortune? I'm sorry if this is a basic question, I'm not sure how this all works.

    Yes that's correct. Underfloor heating is not like radiators, it needs time to heat up and operates at lower temperatures. It's designed to be left on permanently and controlled via thermostats. We have it and it's great.

    Would recommend turning your thermostats right down during summer so that it doesn't kick in because doors are open and the house temporarily drops below 20c. On that note there really isn't any need to have your stats set higher than 20/21c. Would go lower in hallways.

    The running cost will really depend on how well insulated the house is.

    Do your system also have time controls? I would be inclined to inhibit operation of space heating during the night. Is it oil/gas or heat pump?

    There's no time controls on the individual room controls. Just the central heating. Gas central heating.

    The house itself is very well insulated. Once it heats up, it retains the heat very well. Only real concern is the ground floor, which is almost entirely open plan apart from the hall way. Takes a bit longer to heat up. No concerns upstairs.
