Question 1

My radiators are cold at the bottom — what does this mean?

Accepted Answer

** Cold spots at the bottom of radiators usually means sludge and debris has built up in your system — a powerflush will fix this.

Over time, rust, scale, and sludge accumulate inside your central heating system. This causes:

- Cold spots on radiators (especially at the bottom)
- Noisy boiler or banging pipes
- Slow heating times
- Higher energy bills
- Premature boiler failure

> A powerflush clears all the sludge from your system and restores full heating performance. Most homes see an immediate improvement in how quickly radiators heat up.

1. We connect a powerflush machine to your system
2. High-flow water with cleaning chemicals breaks down the sludge
3. Each radiator is flushed individually
4. A magnetic filter is fitted to prevent future build-up
5. Inhibitor is added to protect the system going forward

Question 2

How do I know if I need a powerflush?

Accepted Answer

** If your radiators have cold spots, your boiler is noisy, or your heating is slow to warm up — you probably need a powerflush.

Signs your system needs flushing:

- Radiators cold at the top (need bleeding) or bottom (need flushing)
- Boiler makes banging, kettling, or gurgling noises
- Heating takes a long time to warm the house
- Some radiators don't heat up at all
- Discoloured water when you bleed radiators
- Your energy bills have increased for no obvious reason

! If you're having a new boiler installed, a powerflush is strongly recommended. Fitting a new boiler to a dirty system can damage it and void the warranty.

> A powerflush typically costs between £350 and £600 depending on the number of radiators. It usually takes half a day to complete.

Question 3

Can I bleed my radiators myself?

Accepted Answer

** Yes — bleeding radiators is a simple job most homeowners can do safely. You just need a radiator key.

How to bleed a radiator:

1. Turn your heating on and wait for radiators to warm up
2. Find the radiator that has a cold spot at the top
3. Turn the heating off and wait 10 minutes for the water to settle
4. Place a cloth under the bleed valve (top corner of the radiator)
5. Use a radiator key to slowly turn the valve anti-clockwise
6. You'll hear air hissing out — hold until water starts to drip
7. Close the valve and check your boiler pressure (should be 1–1.5 bar)

> If you're bleeding radiators frequently, it could indicate a bigger issue like a leak or a faulty expansion vessel. Call us for a proper diagnosis.

! Never bleed radiators while the heating is on — the water inside is very hot and under pressure.

Question 4
