    Hello everyone

    I would like to ask a question on something which seems to be a big misconception (at least in my house): heating.

    If you have a gas central heating system, does it cost you less if you leave 3/4 of your radiators in your house off instead of having them all on?

    I am asking this question from an unbiased angle specifically so I can pass this on to my house mates to get a fair response.

    Radiators off = cheaper. Heating water uses gas (unless you have a solar water heater). Gas costs money. A lot of money.

    Yeah it will.I don't mean to patronise but you should only heat the rooms you are using.You can cut your heating bill by buying insulation for your loft,Closing internal doors and turn the radiators down and wear another layer.Oh you could put all the radiators on at like 1-2 before you go to uni or work and still have warm house when you come back.
    Apologies for the essay,Tom

    Thank you for this. And by that do you mean it would be cheaper to "put the heating on" when only 3 radiators are switched on as opposed to 7 for example?

    1000 radiators are going to use more energy than 1 radiators, by extension, 2 radiators are going to use less energy than 8 radiators, so if you leave 3/4 of your radiators off, you use less energy. How the hell can they not realise this?!

    Yep, the less energy you use the cheaper it is, no question about it.

    Yes, fewer radiators on costs less.

    Yep

    If you have a gas fire in any rooms then use that instead of the radiators, too, because the efficiency of burning gas directly for warmth is greater than burning gas to heat water, and thus you'll use less gas than if you turn all the radiators on. Electric fires are also cheap to run, especially since electricity should probably be costing you less at the moment.

    Try not to let the place get too cold in the first place, otherwise you're constantly trying to warm up a freezing cold building, using more gas, that's the mistake we made in our first year in our house.

    (Still remaining unbiased myself )

    The opposing argument is as follows:

    The same amount of energy is used to heat one radiator as it does to heat five. (Admittedly the time of which it takes to heat them fully would be different). If just one radiator was left on, then all the hot water would just go straight to that one instead of being evenly dispursed to the others.

    Any opinions?

    Opening radiator valves to turn them on decreases the pressure in the pipe network. The boiler consequently has to heat and pump more water to maintain a consistent flow of hot water through the network to all radiators as more valves are opened and the pressure is lowered. This is pretty basic stuff :indiff:

    There is the point that a central heating pump will run at the same flow rate no matter how many radiators are turned on.

    However as the flow through fewer radiators will be faster, the energy dissipated will be reduced, and the temperature of the water returning to the system will be higher, resulting in less reheating.

    So, on balance, it seems that having fewer radiators on will be cheaper

    turn off the radiators and wrap up in warm clothing = cheap!
