Why Is My Radiator Cold at the Bottom?
If your radiators are hot at the top but cold at the bottom, your system is likely restricted by “sludge” (iron oxide buildup). This forces your boiler to work harder, driving up your energy bills.
Before installing new units, we highly recommend a Magnacleanse System Flush. This deep clean:
- Removes debris from your pipework.
- Protects your Boiler Installation warranty.
- Improves overall heating speed and efficiency.

Frequently Asked Questions
Can you move a radiator to a different wall?
Yes. We frequently relocate radiators during home renovations. Our engineers can re-route pipework under floorboards or within walls to accommodate your new layout in Cleethorpes, Louth, and beyond.
Do I need to drain the whole system to replace one radiator?
Not always. We often use freezing kits or isolate specific radiators to minimize disruption. However, if your valves are also being replaced, a partial drain-down may be necessary.
What are the benefits of Thermostatic Radiator Valves (TRVs)?
TRVs allow you to set different temperatures for different rooms. By automatically throttling water flow once a room is warm, they can significantly reduce your annual heating costs.
How long does a radiator installation take?
A standard "like-for-like" swap usually takes 1–3 hours. If we are modifying pipework for a vertical designer radiator or performing a system flush, it may take a half-day.

I had a boiler issue, stopped working. He arrived on the same day and ensured that the boiler works while we wait for parts. Kept me updated while parts were coming and asked if the boiler is still working. Always kept the area clean and explained what was the issue. Great job! Definitely recommend.Posted on Google![]()

Fantastic service from Guy, who travelled out to Market Rasen on a Sunday when our boiler stopped working. He was super professional, quick to sort the issue, and great value for money. With kids in the house, getting the heating and hot water back on meant everything, definitely one of those luxuries you take for granted until they’re gone. Really appreciate the effort and would highly recommend.Posted on Google![]()

Guy came to us today which was a wet and cold Sunday afternoon as my Elderly Mother was without heating. After initial contact a time was agreed and Guy arrived on the dot.... He was very good and explained everything he was doing ensuring we understood what was happening. Guy was very clean and there was not a single bit of mess left behind. He made sure we were happy with the work and didnt leave until he was 100% sure the problem was fixed. There was no hard sell with Guy at all he explained a few options for us in the future. Would HIGHLY reccommend Guy and have saved his details for future use. 5☆☆☆☆☆Posted on Google![]()
