    Hi I am new to all this but here goes.We have just received planning for 1.5 story and we looking into heating systems ( I know insulation, insulation is a priority and we are hoping to get our house with an airtight reading of less than 2!!). We want to put underfloor downstairs and rads upstairs. We are putting in a thermal store and connecting our oil, solar and back boiler to it. I hope it will work out okay. I was wondering if anyone could pm me with recommendations with thermal store and underfloor suppliers in the meath/kildare/dublin area. Any advice is appreciated! Thanks

    i'm in the same situation at the moment and could do with the same info. also for all the plumbers out there is underfloor the right approach. both me and the other half work long hours and are only home late in the evening.things change i know and down the line with a family our needs will change. however most of the plumbers ive talked to advised me against it. The most of these know i have a regular plumber and that it is purely for information sake so they have nothing to gain or loose by telling me which way to go.
    sorry for jumping on your thread but any info would be helpful because im hoping to pour shortly.

    The choice to go with underfloor really depends on how well insulated your house is.

    Underfloor is slow reacting and is best suited to a stable indoor environment where there are very small heat losses. If you are insulating to the level of the building regs then for your present lifestyle, radiators will probably be a better choice.

    If your insulation is going to exceed the regs by a wide margin then underfloor might well be a better choice.

    That's my layman's view of the situation, make of it what you will.

    Almost right, but some extra info.......

    'We' are getting to the stage that airtightness is increasing in importance over u-value.

    UFH is only slow-reacting in large mass homes, with heavy screeds. Thinner, more conductive screeds, and lower mass homes (timber etc), react better, and quicker (imho).

    A bigger issue is the mix of UFH and rads, and the setup for that, tbh. Installation and commissioning is at least as important as the technology.

I have neither the time nor the inclination to explain myself to a man who rises and sleeps under the tax revenue and the very freedom to spend it that I provide, and then questions the manner in which I provide it. I would rather you just said "thank you" and went on your way. Otherwise I suggest you pick up a bus pass and get the ********* ********* off the road”
