Heating rooms with high ceiling

    Hello, looking for some advice about high ceiling in a new build.

    I'm hoping to have a high ceiling in a kitchen and dining room area with more high ceiling in a living room space.
    Timber frame built
    High spec of insulation


    What are the best options for heating this space?
    I was thinking of going with ground source underfloor heating.

    Has anyone experience of heating a large high space like this from underfloor heating?
    Has anyone out there used re-circulated hot air to help heat the space.
    All suggestions welcome

    Have you a BER done on your design or a phpp?

    I have 3500mm ceilings. My house is heated by ground source heat pump & ufh. Successful so far. Ambient heat throughout.

    ... and your air tightness target is?

    What follows is exempt from flak under the above::D
    I think you are plum or plumb crazy.

    Just do the math on the extra height.
    Say the room is 50% higher than normal.
    That means you have 50% more wall space to loose heat from at whatever the design U value is.
    The heat loss will be higher than normal because in order to get 22 degrees at seating level it might be 30 plus at the ceiling: maybe less if u have MHVR.

    So whether the UFH will do it is a function of the floor area to room volume and the UFH output for that space will mean much closer pipe spacing, which you need to make sure gets both priced for and more importantly put in.

    High risk of this being done wrong as the fitters assume its all at the same centres throughout the house.

    Thats just the heating, what about the construct cost and the maintenance and lighting issues: recessed down lighters at 3.5m

    Plum or plumb, can't decide:D

    Keep well.

    ^^ completely disagree

    double height, or just 'higher' ceilings can be a fantastic feature in home and shouldnt be discounted due to costs.
    aesthetic and architectural design is very valuable.

    if that was the case we'd all live in rectangular boxes.

    construction standards these days allow for such spaces to be heated easier that traditionally though.

    OP, whatever heating system you decide on, dont make it on the basis of extra height.

    You beat me to it Syd - I disagree as well. I have a 5m hall, and we've just recently completed a build with 5.5m ceilings to Living Room (!) and there's absolutely no reason it can't be done. And it doesn't use UFH either, running rads off a 4kW ASHP.

    Airtightness is the key, not insulation imho.

    Quite apart from technical stuff, I wouldn't give up a key design feature in my house over something like this anyway - otherwise why not just build a shoebox like everyone else ?

    I have a setup like you describe. Our living area, dining area, hallway and kitchen is all open and heated using underfloor heating. There is a thermostat outside that is used to regulate the temperature inside and each area above has it's own temperature control. Heat is taken in from the kitchen, bathrooms and laundry room and circulated around the house to other rooms, this system also takes in air from outside depending on the temperature and circulates it around the house. Works well and is low maintenance. I have a system from Vallox for circulating the air.

    Thanks for the feedback people

    currently I am arguing with the architect over the viability of the higher ceilings in terms of costs, heating, finish etc

    I would like the higher ceiling, but am being put off by things I am reading about heating a higher ceiling area.
    I'm interested in any solutions people have installed or seen used in houses to ensure pooling of warm air doesn't occur at the apex of the ceiling

    BER assessment has not been done as the design is not finalised.
    I intend to go on an air-tightness course before any build commences

    Hi Jester77,
    interesting looking at the Vallox system you linked to.... do they have an agent in Ireland (I cannot see one mentioned on their site) or did you buy direct/through UK agent?

    Any issues with installing it? Did you do it yourself? How does it compare to the likes of Aereco etc?

    Thanks,
    sami

    Well unless your architect is paying for your mortgage, or living in the house with you, I can't see what he wants git to do with it: it's your house....
