Radiator Hacks: Simple Adjustments to Reduce Heating Bills

To save moneyon heating bills while keeping your home comfortable, it’s important to make your central heating system work better. Energy prices are high right now, so making changes to your heating system is a great idea. Radiators are a key part of this. Even small changes can greatly improve energy usage and help keep your home at a nice temperature.

According to the Energy Saving Trust, heating costs make up around 55% of what a UK household spends on energy bills. Hot water adds another 20%. You can save money by improving radiator performance. Using heating controls smartly can also help. This reduces heat loss and lowers carbon emissions. In total, these tips can save you hundreds of pounds every year.

1. Bleed Your Radiators to Remove Trapped Air

If your radiators feel cold in some areas, they are not heating well. Air stuck inside stops hot water from flowing right. This makes your central heating system work harder to make the same amount of heat.

Signs That Your Radiator Needs Bleeding:

• The top of your radiator is cool, but the bottom is warm.
• You hear bubbling noises when the heating system is working.
• Your heating takes more time than normal to get warm.

How to Bleed a Radiator Properly:

• First, turn off your central heating system and let the radiators cool down.
• Next, use a radiator key or a flat-head screwdriver to open the valve at the top of your radiator.
• Slowly turn the valve to the left until you hear a hissing sound. This means air is escaping.
• When you see water start to drip out, close the valve tightly.
• Finally, turn your heating system back on and check if the radiator heats evenly.

A good radiator can save you money. When your radiator works well, it heats your home more efficiently. This means less energy is wasted. You could save up to £75 each year on your heating bills.

2. Adjust Radiator Valves for Even Heat Distribution

Many homes have heating issues. Some rooms may feel very warm while others feel cold. This usually occurs when the radiator valves are not balanced right. When this happens, energy useis not efficient, which can lead to higher heating bills.

How to Balance Your Radiators for Even Heat:

• First, turn off your heating system and let the radiators cool down.
• Next, find the radiator that is closest to the boiler. This one usually heats up the fastest.
• Slightly open the lockshield valve, which is typically at the bottom of the radiator.
• Now, go to the radiator that is the furthest from the boiler. Open that valve more to help it heat up well.
• Keep doing this for all radiators to make sure they heat evenly.

A good heating system can save you money. It eases the load on the boiler and central heating controls. You can save up to £100 each year on energy bills.

3. Use Thermostatic Radiator Valves (TRVs) to Control Room Temperatures

Thermostatic radiator valves (TRVs) let you control the temperature in each room separately. This means you do not have to heat every room to the same temperature.

Benefits of TRVs:

• Let each room have its own temperature (for example, make the living room warmer and spare bedrooms cooler).
• Stop overheating in rooms that don’t get used much, which saves energy.
• Help central heating systems work better.

Recommended Settings for TRVs:

• Living Room / Main Spaces: 18-21°C
• Bedrooms: 16-18°C
• Spare Bedroom / Unused Rooms: 15°C (instead of turning off the radiator completely)

Installing TRVs can lower heating costs by up to 10%. This means you could save around £120 each year.

4. Set Your Boiler Flow Temperature to 60°C for Efficiency

Many boilers run at hotter temperatures than needed. This wastes energy and makes gas bills higher. You can save energy by changing your boiler flow temperature to 60°C. The default setting is usually 70-80°C. This change can help with energy efficiency. The best part is that you won’t notice a change in comfort.

Why Lowering Boiler Flow Temperature Helps

• Many boilers are set to a temperature that is too high, leading to extra energy use.
• When you lower the boiler flow temperature, the system works better. This makes your home warm without using too much gas.
• New combi boilers run better at lower temperatures. They cut down on heat loss and still give you enough hot water for everyday needs.

How to Adjust Your Boiler Flow Temperature:

1. Locate the boiler temperature dial– Look for a dial or digital setting for flow temperature on the front panel of your boiler.
2. Find the correct setting– Most boilers have two temperature controls: one for hot water and another for central heating. Change the setting for central heating flow temperature.
3. Lower the temperature to 60°C– If it’s set to 70-80°C, reduce it to 60°C. This keeps your heating comfortable and helps use less energy.
4. Monitor performance– After you make the change, check if the radiators are heating up well. If they are not working right, increase the setting a bit.

5. Prevent Heat Loss with Radiator Reflectors

If your radiators are on outside walls, much of the heat goes out instead of warming your home. Radiator reflectors can help bounce the heat back into the room.

How to Install Radiator Reflectors:

• Cut reflective foil to the size needed to fit behind the radiator.
• Stick it to the wall with adhesive strips.
• Make sure the shiny side is facing the radiator. This will help reflect more heat back into the room.

Using radiator reflectors can help you save money. They can cut heat loss by up to 30%. This can lead to a saving of £50 a year on heating costs.

6. Keep Radiators Clear for Maximum Heat Circulation

Blocking radiators with furniture, curtains, or laundry can stop heat from getting out. This makes your heating system work harder to keep things warm.

Tips to Keep Radiators Unobstructed:

• Keep sofas, beds, or desks at least 15cm away from the radiator.
• Do not hang clothes or towels on radiators; use a heated airer instead.
• Make sure curtains do not block the radiator, as this will trap heat.

Maximising the heat output of your radiator can help reduce the stress on your boiler. This can lead to savings of £100 to £150 each year.

7. Use a Timer and Programmer to Reduce Heating Costs

Leaving the heating on all day can use a lot of energy. A timer or programmer helps you create heating schedules. This way, it can fit your lifestyle better.

Ideal Heating Schedule:

• Morning: 30 minutes before you wake up.
• Evening: 1 hour before you get home.
• Night: Turn off or set the temperature to 15°C while you sleep.

Using heating timers the right way can help lower heating bills by 15%. This means you can save about £150 to £200 each year.

8. Use Smart Radiator Valves for Automated Efficiency

Smart radiator valves change the heating levels based on the room temperature and how much you use the space. This helps to cut down on heating costs without any extra work.

Advantages of Smart Radiator Valves:

• Let you control it from your smartphone app.
• Lower the heat in rooms that are not being used.
• Connect with smart thermostats to save more energy.

Smart radiator valves can help save money on heating bills. You can save up to 20%. This means you may save between £200 and £250 each year.

9. Keep Doors Closed to Trap Heat in Rooms

Heat can easily get out into hallways, staircases, and unused rooms when doors are open. This makes your central heating system work harder to keep the temperature of the water in the radiators steady. As a result, your heating costs may go up.

How to Prevent Heat Loss from Open Doors:

• Keep doors closed in spare bedrooms, hallways, and areas you don’t use much. This stops heat from leaving.
• Use draught excluders. They will help keep cold air from coming in under doors.
• Think about putting up internal door curtains. They can add extra insulation in bigger, open areas.

You can save money by closing doors to reduce heat loss. This can lower your heating bills by as much as £100 each year.

10. Insulate Hot Water Pipes and Your Hot Water Tank

Many homes waste heat through hot water pipes and tanks. This makes the boiler work harder. It tries to keep a comfortable temperature for showers, baths, and central heating.

How to Insulate Hot Water Systems:

• Put a hot water jacket around your hot water tank to stop heat from escaping.
• Insulate exposed pipes with foam to keep the hot water warm longer.
• Take shorter showers. This will use less hot water and help your boiler work better.

You can save money by insulating your hot water system. This could lower your heating costs by £80 to £150 each year.

11. Lower Your Thermostat by 1°C to Cut Heating Costs

The temperature in your home is very important for energy use. A lot of people make their homes too hot. They don’t know that turning down the thermostat a little can help them save a lot of money.

Ideal Thermostat Settings for Energy Efficiency:

• Living areas: 64-70°F
• Bedrooms: 61-64°F
• Unused rooms: 59°F

How to Make This Change Easier:

• Slowly lower the room thermostat by 1°C at a time. Keep going until you find the lowest comfortable temperature.
• Instead of turning up the heating, use blankets or heated throws to stay warm.
• Set cooler temperatures at different times of the day. For example, lower the thermostat while you are sleeping.

Lowering your thermostat by only 1°C can reduce heating costs by up to 10%. This could save you between £145 and £200 each year.

12. Use Your Radiators and Boiler More Efficiently in Autumn and Winter

Many homeowners start heating their homes too soon or keep it running longer than needed. This can lead to higher energy bills.

Seasonal Heating Tips to Save Money:

• Wait to turn on central heating until you really need it. Wear warm clothes and use blankets in early autumn.
• Turn off radiators in rooms that you do not use. Avoid heating empty places.
• Set your heating to warm up slowly instead of switching it on to full power right away.

By using smarter heating habits in autumn and winter, you can save energy. This could help you save between £100 and £150 every year.
