Older type well insulated Homes have solid internal walls, these act as massive thermal stores, in long cold external temperatures keeping the temp buffer stable, therefor continuous heating of a slightly lower than required and boost when the home is occupied Stove is most efficient, stops lots of cycling of central heating systems.
The idea that using heat now can save on heat later literally goes against the first law of thermodynamics. The simplest way to explain this is by using a leaky bucket as a metaphor for your house. You can keep it topped up full; you can keep it topped up to a lower level reducing the rate of loss ; or you can let it empty completely stopping the loss entirely. If you allow it to empty completely before filling it back up when needed, this simply cannot use more water than keeping it topped up to a low level the entire time.
The amount of insulation is exactly the same as the size of the leak. A smaller leak will lose less water over time but the principle remains the same as a larger leak. Been there, done it. We had LPG when first married. Our bungalow was over insulated if there can be such a thing — we built the property ourselves and put rock wool under the voided floor, hanging the insulation in netting between the floor joists, but still keeping a void, super insulated the loft and used insulated blocks for the inner walls.
For a week we put the heating on constant, but at a low temperature and boosted it for an hour when we came home. The following week, in very similar weather conditions, we put the heating on timed — 2 hours am and pm. We took meter readings at the beginning and end of each week and found that leaving it on a low setting constantly was more economical. A building in the heating season losses heat at a rate that depends on the difference between inside and outside temperature. Remember your first day in science?
Heat goes to cold? If you heat a house to above the outside temperature you lose heat. It is called heat loss for a reason. That is energy. You have to replace it if you want to maintain the temperature. Next, when does your boiler operate most efficiently? When it has the coldest return temperature i. This is because the boiler then gives back the latent heat component of the flue gas heat and hence you see plumes of condensation coming out your flue.
If you have an old house, put the thermostat on a reduced temperature to protect the fabric against condensation while you are away especially if unoccupied for a long time.
Would you keep a kettle boiling all day because you think it will be cheaper than heating it up everytime you want a cuppa? Would you leave your car running overnight so it was nice and toasty for the drive to work in the morning because it is better to keep it hot than warm it up each day?
You know you are wrong to all those who continue the myth and to those realising this misguided direction do not follow, stop them with the above simple and accurate statement. I just read there were a lot more comments on this as I was about to post. There are obviously still too many people that think they are educated in this state but have no idea of fundamentals.
I appreciate that electricity is more expensive, but we are considering buying a retirement home part of a converted stable block well insulated, but with only electric Underfloor heating.
No figures available for annual running costs. Thanks for posting about the Energy Efficient Boilers that help to maintain the thermal effect. Its really helpful. What do you think in that situatiod? Regards, Mike OR. Do you mean to say that in this example, there is no energy saving when the house is only heated when needed? WC constantly adjusts the boiler flow temperature to the outdoor temperature and, if set correctly, can exactly match the heat loss of the building in all temperatures.
Catch-up requires a boiler to exceed the building heat loss. Therefore, you can either a run WC; or b run set-back. Plus, as the temperature is constant, most people are able to set it around 1C lower than intermittent heating, as the fabric of the building and furniture are also already warm. Is intermittent heating more efficient than continuous when running WC? Sorry this artical is wrong. It is always more energy efficient to use the heating when it is required.
So time clock with a room thermostate is best in every case. I can show the maths! I have also see the test data. To run a system all the tume will be more efficent on the system but will still cost you more! To run a system all the time will be more efficent on the system but will still cost you more! Unless maybe its only off for an hour a day. Insulation is key though so a lot of this artical is good.
Check out bri website for accurate info. Definitely worth it on external walls as they tend to leech heat, but also generally a good idea for party walls too! They easily pay for themselves over their lifetime. We have a constant boiler and at this present time the boiler needs firing up manually at least twice a day if the boiler is turned off. Will it be ok if we turn the radiators off and thermostat down and still enable the boiler to come on in order that we have hot water.
Will this still waste money? I wanted to find out about heating my water. This article only talks about central heating. I think that since the rate of cooling of a house is greater when hot more heat is lost if the heating remains on rather than turning it off.
We have a elm LeBlanc gas boiler that Heats radiators and water. The boiler is 17 years old and is no problem. Will it need to be replaced for safety. I had an old Leblanc boiler in a lettings house many moons ago and it was replaced with a Potterton Profile and more recently with a condensing boiler which they all are now and can recommend the Baxi Potterton which has a long guarantee and easy to fit and service etc Plumbers also recommend Ideal Vogue I enjoy one in my home and rather dearer the Worcester Bosch Greenstar and Vaillant Ecotech or Viessman boilers.
One will have to set the thermostat to high the max they want the room heated to. Set too low and the house feels cold, Thermostat could be a life saver if the house is too hot like the bedroom. My house has no thermostat inside and one morning woke up with my tongue sticking to the roof of my mouth, it all do the radiator was on full black during the summer, my bedroom door was closed, I live alone.
Think I am lucky I lived!!!! You could cover this on your page too feel free to share my story. It will be more cost-effective to heat the home as and when you need it, as any heat you generate will be lost fairly quickly through the walls, so if you try and maintain that warmer temperature all the time, your boiler is going to have worked incredibly hard.
Interesting approach but you are not taking into account the moisture content of air in the property. Warm air holds a lot of moisture, and when the heating goes off, it condenses. In an old solid walled property, it is ESSENTIAL that the fabric temperature does not drop below dew point or you will experience damp problemsx — interstitial condensation in walls for eg, and mould.
You NEED to keep walls above dew point — which for an average home in winter is going to be 10 degrees or more. This in turn means you need to keep the place heated to at least 15 deg C all the time — cyclical heating allows walls to cool down, and damp problems start.
You can also look to control moisture by installing humidity controlled extraction in bathrooms and kitchens for eg. Set thermostat at either degrees..
Main bedroom 3 sometimes 2 Bathroom 2,other bedrooms 2. House stays warm and bills work out a lot cheaper than turning on- off!! I have never used my fire since doing this either so saving big time. Necessary cookies are absolutely essential for the website to function properly.

Toggle navigation. Is it cheaper to leave your heating on all the time or turn it on and off? January 21, Therefore, this type of heater is safe to touch and safe to leave on throughout the night.
Electric space heater If left on for too long, a space heater can damage the outlet it's plugged into and act as a fire hazard. Vented propane heater Similar to space heaters, this type of heater can release carbon monoxide and risk starting fires.
Be sure to switch off your vented propane heater before bed. Place your heater in an open space, away from furniture, clothes, and curtains. Use lower power settings throughout the night. Avoid the carbon monoxide poisoning by turning off the heater and unplugging it before leaving the room or going to the bed. Signs of too much carbon monoxide in the rooms include headache, dizziness, abdominal pain, discomfort, vomiting, nausea and weakness.
Convection heaters are the ones that are filled with heat, they transfer oil to radiate the heat from the external surface area. The heater comes with a thermostat to regulate the temperature. These heaters are low maintenance and do not require regular cleaning. The heat from these heaters spreads slowly as compared to other heaters.
These room heaters spread the heat through a metallic coil that glows upon being heated electrically. The nearby areas are first heated, which further spreads the heat in the entire room. These heaters work on convection mode and can heat a closed room very quickly.
But because a fan is always running inside it, they are noisy and unsafe to be used in humid conditions. Radiant heaters provide you with instant heat through the infrared rays. These heaters are best for people who are prone to dust allergies because they heat the objects and not the air around them. Though fan heaters turn out to be the cheapest ones, an oil-filled heater is better as it heats the entire room in an even manner.
Fan heaters and infrared heaters reduce the oxygen levels and humidity in the room which can cause dry eyes and nasal blockage over the long term. It is advisable to keep a bucket of water in the corner of the room or use a humidifier to prevent significant dehydration. Oil-filled room heaters do not burn oxygen nor reduce humidity while heating the room. They are usually the best choices for children and the elderly as they do not cause dehydration.
They are the best option as they do not cause any suffocation or dry eyes, skin rashes.

Go to TOI. The Times of India. How does your zodiac sign flirt? Our heating temperature gets set to low overnight so it's not too hot but never gets too cold, then it turns up shortly before we get up so we can get up in the warmth.
In answer to Ria20cua. No, wouldn't be able to hack it. Sometimes I'll put it on when going to bed and tell OH to knock it off when he gets home a few hours later , But I always wake up to knock it off. When the heating on the flats roasting but as soon as its off its freezing. We can't win lol xx. Benefits and entitlements He doesn't give me any money at all. Benefits and entitlements Moving in with partner- will I lose all housing benefit? Benefits and entitlements Keeping heating on low 24hours.
No never, I quite like the room being cold at night I always have an extra thick duvet and toasty PJ's so it's lovely and warm, I love getting up to go to the loo and being freezing then jumping back into a lovely warm bed, I always doze back off quicker. Maybe I'm just strange lol. Our beds always warm anyway since DD has decided she prefers it to her own bed. OH works nights and gets in around 6ish so he turns it on and then it's nice and warm for when we get up.
Can't find your answer? No it needs to go off atleast hr or 2before i go bed and i need the bedroom window open also. OMG I've turned into my parents lol. Yes when it gets cold I leave it on low all night. We have a pre payment meater so I can see exactly how much its costing us. Last year I found it cost me an extra 30p per day to have it on constantly a bit lower then using it for a short time in bigger blasts to warm the house.
