There are two temperature settings that you need to think about when you first decide to turn on your central heating for the autumn and winter months.
The first is your thermostat setting. This determines what you want the air temperature to be in your home. The lower it is, the cheaper your heating will be, but you don't want to leave it so low that it jeopardises your health.
If you are over 65, not very mobile or have a health condition, the NHS recommends keeping your home at a minimum of 18 degrees over the winter months. If you have a baby, the NHS recommends keeping to a temperature of between 16 and 20 degrees. FIt, healthy adults can be a bit more experimental with their thermostat settings.
central heating flow temperatureMost of us have condensing combi boilers. If you do, you can save money by setting your heating flow temperature to 60-65°C. If you've never adjusted it, it's likely to be much higher than that, which means you're using more energy each time your boiler comes on. Note that you shouldn't do this if you have a regular or system boiler that has a water storage tank.
You can adjust your flow temperature easily yourself. The perfect number will depend on your home - we recommend setting it to 65°C first of all and working down if your rooms are still warming up effectively.

It’s not likely that an electric heater will be cheaper than gas central heating to heat up your home. Although central heating can be pricey, it spreads warmth evenly around your home. Electric heaters cost more to run for the amount of heat you’ll get. But they can be useful for a short, concentrated burst of heat in a small area.
Most of the electric heaters we’ve tested cost around 60p per hour to run. If you’ve switched the central heating off, the warmth from the heater will quickly dissipate in a cold home when it’s turned off.
If your home is small, such as a studio flat, and is well insulated, an electric heater might cost less than the central heating. If it’s bigger than that you’re better off with your central heating for day-to-day warmth.

If you're keen to keep away from the thermostat, it's important to make sure your body stays warm by wrapping up as much as you can. We tested thermals last winter, and we found paying more for them didn't mean they kept you any warmer than cheaper options, so we'd advise not paying out more than you need to.
However, our testing did revealed that it's worth investing in thermals over just adding another cotton layer. The dedicated thermals we tested did keep you warmer than just putting on an extra t-shirt.
Our testing also discovered that there's no need to pay more for a pricey hot water bottle. However, do spend on a thicker hot water bottle cover, as you'll feel the benefit in terms of one kettle load keeping you warm for longer.

One of the cheapest ways we've found to keep yourself cosy is to wrap up in an electric blanket.
Our tests have found they typically cost between 2p to 5p an hour to run on their highest setting - much less than the average fan heater.
This means if you used an electric blanket for three hours a night, every night, for half the year, the cheapest-to-run options would only cost about £11 in total, versus £38 for the most expensive.
You can reduce the cost further by setting the blanket to a lower setting, or turning it off sooner. The blanket will still remain warm for a couple of hours after turning the power off, so you feel the benefit without the cost ticking up.

Lowering heating costs with DIY jobs around your home can be a really worthwhile way to spend a weekend, and you'll save money and reduce energy consumption in the long run.
These are some of the affordable DIY ways to lower heating costs we think are worth doing:
Identify and seal any drafts in your home.Install door sweeps and draft excluders at the base of external doorsPlace rugs or carpets on cold hard floorsApply window film or use thermal curtains to insulate windowsLag exposed hot water pipesUse a chimney draught excluderThe effectiveness of these methods can vary depending on your home's size, layout, and existing insulation. It's best to start with the most cost-effective measures and then consider more significant investments like additional insulation or a new heating system if needed. Good DIY and hardware shops should have plenty of cheap materials to get you started.

While it is true that turning your thermostat down a degree or two will save money, it’s a myth that having it perpetually on low, whether you need it on or not, will be cheaper.
For most homes, it's better to only have the heating on when you actually need it. You don't want to be paying for heating when you're not in a room, or even at home at all.
However, there is some truth to the fact that a steady, consistent approach is often more economical than sharp swings in temperature that see your home getting very hot and then very cold again. Don’t get tempted to keep cranking the thermostat very high and turning it down again drastically, as this could negate savings, lead to condensation and make your home uncomfortable.
What works for a very energy-efficient home won’t necessarily work for a less efficient one, so if you're keen to know exactly what will work best in your home, it's worth seeking advice from a heating engineer. It's something we recommend you ask about while you're having your boiler serviced.
