Heating is something most of us take for granted until it stops working properly. Whether it’s a boiler that’s acting up, radiators that don’t get hot, or rising gas bills, it all points to the same thing: your heating system needs a bit of care.
Why Bother with Heating Maintenance?
Look, no one wants to spend more time or money on their heating than they have to. But giving your system a bit of attention once in a while can save you headaches later on.
Here’s why it’s worth doing:
-
It keeps your bills down – A boiler that’s running well uses less gas
-
It makes your system last longer – You won’t need to replace it as often
-
It keeps your home warm when it matters – Especially during freezing UK winters
-
It helps catch small problems before they get worse – And cost more to fix
What’s Actually in Your Heating System?
You don’t need to know every pipe and part, but it helps to understand the basics:
-
Boiler – Heats the water
-
Radiators – Spread the heat around your home
-
Thermostat – Tells the boiler when to turn on or off
-
Pipes – Carry hot water to the radiators
-
Pump – Keeps water moving through the system
If any of these stop working, the whole setup can struggle.
Simple Things You Can Do Yourself
Here are a few quick checks you can do without calling anyone in:
1. Bleed Your Radiators
If your radiator is warm at the bottom but cold at the top, it’s probably got trapped air. You can bleed it with a radiator key and a towel — easy job, takes five minutes.
2. Check Your Boiler Pressure
Most boilers need to be between 1 and 2 bars. If the pressure is too low, your heating might not work properly. Your boiler should have a little gauge on the front. If it’s low, you can usually top it up with the filling loop underneath.
3. Keep It Clean and Clear
Don’t block radiators with furniture. And give them a wipe-down now and then — it helps with airflow. Same goes for boiler cupboards — keep them clear.
4. Use Your Thermostat Smartly
If you’ve got a programmable thermostat, set it to match your routine. No point heating the house when you’re out all day.
Things You Should Get a Professional To Do
Not everything should be DIY. Some jobs are best left to trained engineers (especially anything involving gas).
1. Annual Boiler Service
Every boiler should be serviced once a year by a Gas Safe engineer. It’s like an MOT for your heating. They’ll check for leaks, clean it inside, and make sure it’s running safely.
2. Strange Noises or Smells
If your boiler starts making knocking sounds, or you smell anything odd, turn it off and call someone. Don’t take chances with gas.
3. Radiators Not Heating Up Properly
If you’ve bled them and they’re still not getting warm, it might be sludge in the system. A professional can do a power flush to sort that.
4. New Parts or Upgrades
Whether it’s a new pump, thermostat, or full boiler replacement, it needs to be done properly. That’s where we come in.
Best Time to Check Your Heating
Most people don’t think about heating until they’re cold — but a bit of planning goes a long way. Here’s what to do, season by season:
1. Autumn
-
Test the boiler before it gets cold
-
Bleed the radiators
-
Book in your service (it’s less busy than winter)
2. Winter
-
Keep an eye on pressure
-
Use timers to save energy
-
Watch out for frozen pipes if it gets really cold
3. Spring
-
Turn off the heating if you don’t need it
-
Use this time to get any repairs sorted before the next cold snap
4. Summer
-
Run the heating once in a while to keep it ticking over
-
Good time to replace or upgrade parts
Saving Money and Using Less Energy
Heating takes up a big chunk of your energy bill, especially during colder months. Here’s how to keep costs under control:
-
Turn your thermostat down by 1°C – you’ll barely notice the difference, but your bill will
-
Only heat the rooms you use
-
Use radiator valves to control individual radiators
-
Draw your curtains at night to keep the heat in
-
Fit draught excluders around doors and windows
Frequently Asked Questions
1. Do I really need to service my boiler every year?
Yes — it helps keep things running safely and stops small issues turning into big, costly ones later on.
2. Why are my radiators cold at the top but hot at the bottom?
They likely need bleeding to get rid of trapped air. It’s a simple job you can do with a radiator key.
3. What should my boiler pressure be?
Most boilers work best between 1 and 2 bars. You can check the gauge on the front of the boiler.
4. My heating takes ages to warm up — is that normal?
Not really. Could be air in the system, low pressure, or your boiler’s struggling. Worth getting it looked at.
5. Can I fix a small leak from a radiator myself?
If it’s just a loose valve, you might be able to tighten it. Anything more – call a professional.
6. How do I know if my thermostat’s working properly?
If your heating isn’t turning on when it should, or the room feels too hot or cold, it might be faulty.
7. Is it bad to turn the heating off completely in summer?
No, but run it for 5–10 minutes once in a while to stop parts from seizing up.
8. What are signs that my boiler might be on its way out?
Noises, frequent breakdowns, low pressure, and rising energy bills could all be signs it’s time for a replacement.
9. Will a smart thermostat save me money?
Yes – it helps you heat only when you need to, and avoids wasting energy.
10. Can you help if I’ve got an old system but don’t want to replace it yet?
Definitely. We can do a full service, flush out the system, and make small tweaks to keep it going longer.
