Question 1

What does balancing a central heating system involve?

Accepted Answer

Balancing means adjusting the flow to each radiator so heat is distributed evenly, room by room, instead of the nearest radiators taking most of the heat. We usually balance the system alongside fitting or adjusting TRVs once it has been cleaned.

Question 2

What are TRVs and why would I want them?

Accepted Answer

Thermostatic radiator valves let you set an individual temperature for each radiator, so you are not heating rooms you rarely use to the same level as the rest of the house. They are a simple, low-cost way to improve comfort and control running costs.

Question 3

How long does a boiler installation typically take?

Accepted Answer

A straightforward like-for-like combi boiler swap usually takes one working day. Converting from a conventional or system boiler to a combi, or fitting a new unvented cylinder alongside the installation, can take one to two days depending on the pipework involved. We confirm the expected timescale in your written quote.

Question 4

Why are my radiators cold at the bottom but hot at the top?

Accepted Answer

This usually means sludge or debris has settled at the bottom of the radiator, restricting water flow. A powerflush is typically the right fix rather than repeatedly bleeding it, which will not clear a sludge build-up.

Question 5

What does a banging or kettling boiler noise mean?

Accepted Answer

Banging or kettling noises usually mean sludge or debris has built up around the heat exchanger or in the system, restricting flow. It is often resolved with a powerflush, though we always check the system first before recommending one.

Question 6

Will a powerflush damage an older system?

Accepted Answer

A powerflush is a standard, well-established maintenance procedure, but on a very old or already fragile system there is a small risk of exposing existing weak points. We always assess your system first and are upfront if we think a gentler approach is more appropriate.

Question 7

What is a powerflush and do I need one?

Accepted Answer

A powerflush forces cleaning fluid through your heating system at high velocity to remove built-up sludge, rust and debris. If radiators run cold in patches, or the boiler makes banging or kettling noises, it is often the recommended first step before any other work.

Question 8

What does a magnetic filter do?

Accepted Answer

A magnetic filter sits on the pipework near your boiler and continuously traps metallic sludge and debris, protecting the boiler heat exchanger from damage. Most manufacturers now recommend or require one to keep the warranty valid, which makes it a cheap, worthwhile addition.

Question 9

Do I always need a new boiler if some rooms stay cold?

Accepted Answer

No. Cold rooms and uneven radiators are often a central heating problem, not a boiler fault, and a powerflush, a new magnetic filter or some balancing is frequently a far cheaper fix. We always recommend the proportionate solution first.
