Heating 24/7 Versus heating as required.

      Carried out a relatively rudimentary trial of keeping the heating on 24/7 for one week and then heating as required for the following week. As expected having the heating on all the time used more gas but was, in general, more pleasant to live with.

      In the first week heating 24/7 I used 19 cubic feet of gas. The next week used 14 cubic feet.

      A quick search of the internet showed how to convert from cubic feet to Kwh.

      The formula is as follows: gas units used x correction factor (1.02264) x imperial to metric conversion factor (2.83) x calorific value (38.9) divided by kilowatt-hour conversion factor (3.6) = kWh in cubic feet. To calculate a bill, multiply kWh in cubic feet by the unit price in your agreed contract.

        An interesting experiment @Brydo?

          So Brydo, what was the actual difference in price to you.

            If my math is correct, I can not guarantee that lol. It cost me £160 for 24/7 and £118 for when required.

              We are trying a new routine, we used to have it on morning and evening, but now trying this. We have it on low during the day (18c) then 20c in the evening, off at 10pm. On at 7am for an hour at 20c, then bank to 18c.

                We have been doing that for years. Keep rad stat valves in rooms not used often on low settings. Lounge, dining area, bathroom, main bedroom on programable timer to those settings. Find it best for the home and us for the house to maintain some background heat. Being retired at home most of the day need to keep warm. We have a well insulated home so it keeps the heat in.

                  What temp do you have your boiler at, I have it set at 46*C for the radiators.

                    Have a Baxi 600 combi boiler, have the boiler temp set @ 65c, as recomended by Baxi. Good heat output from the radiators without them getting too hot.

                      Sorry figures above are incorrect, told you lol, I used the price per Kwh for electricity rather than gas. The correct ?numbers are £53 and £39.

                        @Tvs try turning it down and see if you feel any difference. You will almost certainly save some money ?.

                        In the years to come we will be using heat pumps to heat our houses these are set at input temp less than 50*C or less for maximum efficiency.

                          Have tried lower settings but the rooms took longer to get to a comfortable temperature. If having background heating on 24hrs maybe a lower temp would work. But prefer to target heat the rooms in use when I need.

                          House has Cavity Wall, Underfloor & loft insulation, A+ glazing, Composite door. So it helps keep heating costs down.

                          BAXI – What temperature should my boiler be set at in winter?
                          We all want to stay cosy in the winter. Some cosier than others. There’s no magic number for the ideal temperature. If you’re looking for a good balance of warmth and efficiency, you want to set your boiler to at least 65°C. Setting it a few degrees higher won’t hurt. But it’s important not to set it any lower than that. This is so bacteria in the water doesn’t grow, and cause nasty things like Legionella.

                            @Tvs unless your thinking of drinking the water in your radiators you won’t get legionella ?? there will be a temp for radiators and one for hot water. There is a very slim chance of getting legionella from a combo boiler as there is no standing water as there would be in a tank. Your mains water is moving most of the time due to day to day living, dish washers, washing machines, cups of tea etc

                              Agree Brydo, have experimented with lower boiler settings and find the sweet spot is @ 65c for us.

                                  We have boiler set at 60c. It takes the house longer to get up to temperature, that’s why we’re trying leaving it on at 18c during the day.
