Is a buffer tank needed for Under Floor Heating?

    Im building a house at the minute and planning to put under floor heating in. Was going to use oil boiler initially and want to hear if a buffer tank is needed. Ive been told that short cycling of an oil boiler can push up the running costs.

    Long term i plan to use alternative heating when oil becomes more expensive and plan to use buffer tank then. Im not intentionaly being tight by not putting in the buffer now, its just that the budget is getting smaller and if i can save the cost of a buffer now it will help.

    Thanks, any input greatfully recieved.

    I believe that oil (or even Gas) is still the most convienient form of heating and can be cost effective/ efficient if you comply with current heating regulations i.e Building regs Part L.( Ensure that your plumber and electrician talk to each other properly..... or speak to a Domestic Heating Engineer).
    You should be able to independently programme on and off your heating upstairs or downstairs or hot water only.
    Underfloor heating usually allows localised control but also consider Thermostatic Radiator Valves(TRV's) on any Radiators (this will give you additional control in every room).

    Having an alternative localised heating method (solid fuel stove or similar) is a better idea. Underfloor heating is best suited for large open plan living therefore a stove would give you a comfort factor during winter/ cold nights.
    Solid Fuel Boiler/stove can not be connected to heating pipes if underfloor is fitted unless a buffer tank and additional components are utilised however but the expenses and additional work and controls is prohibitive.

    The Heating system is the back bone of your home and will be expensive and possibly involve major disruption from builders work to make alterations afterwards.
    :eek:
    Also put every effort in insulating walls and ceilings and attic spaces as this will reduce your energy cost long term.

    Thanks for that, its a new build that i am doing now and thought of underfloor heating as i want to "future proof" the house so to speak. As you mentioned alterations after the house is built will be both disruptive and expensive.

    Other forms of heating work at lower water temperatures so lend themselves to underfloor and need a buffer tank but what i want to know is is a buffer tank necessary if i am running an underfloor heating system with an oil boiler.

    Thanks
