Central heating

Full central heating systems, radiator work, valves, pumps and powerflushing across Bexley and North Kent. New systems designed around the house rather than copied off the last one, and existing systems balanced so every room actually gets to temperature.

What is included

Every central heating system, covered.

Full system installs

Boiler, cylinder where one is needed, pipework, radiators and controls, planned around the rooms you use and the way the house is built rather than a standard layout.

Radiators, swaps and additions

New radiators, bigger radiators where a room never gets warm, vertical rads where wall space is tight, and extra circuits into extensions and loft conversions.

Powerflushing and system cleaning

Cold spots at the bottom of radiators and a boiler that keeps clogging usually mean sludge. A powerflush with a magnetic filter fitted afterwards clears it and keeps it clear.

Balancing and zone valves

Flow set across the whole system so the far bedroom heats as well as the hall, plus zone valves and thermostats where one heating pattern for the whole house does not suit how you live.

Pumps, valves and pipework

Failed pumps, passing diverter valves, seized TRVs, noisy pipework and leaking joints, sorted as a system rather than as a list of individual parts.

Upgrades that cut running cost

Better controls, TRVs on every radiator, a properly balanced system and pipework insulated where it runs cold. None of it is glamorous and all of it shows up on the bill.

Questions

Asked and answered.

Why are some of my radiators cold at the bottom?

That is sludge, which is corrosion debris settling in the bottom of the radiator and blocking the flow. A powerflush clears it out, and a magnetic filter plus inhibitor stops it building back up. If the cold patch is at the top instead it is air, and that is a five minute bleed.

Can you add radiators to an existing system?

Usually yes. The question is whether the boiler and the pipework have the capacity for the extra load, which gets checked before anything is promised. If the system is already at its limit you get told what would need upgrading and what that costs.

How long does a full central heating install take?

A typical three bedroom house is around three to five days depending on how much pipework has to be replaced and whether floors have to come up. You get a programme before it starts, and the heating is never left off overnight without you knowing about it.

What is balancing and does it matter?

Balancing is setting the flow through each radiator so the heat is shared out evenly instead of the first few radiators taking it all. It costs nothing but time and it is the difference between a system that works and one that only heats half the house.

Can you fit smart heating controls?

Yes. Wireless room stats, programmable controls and app-based systems all get fitted and set up. They are worth it where the house is used at different times in different rooms, and less worth it in a small flat, which is what you will be told if you ask.
