Our Central Heating Process
Free Site Assessment
We visit your Erith property, review the existing system or plan for a new installation, and note any constraints — particularly pipework sizing in older properties — before providing a written quote.
Planning and Scheduling
We confirm the scope, order required materials, and agree a start date. Radiator swaps and TRV work can often be done in a single day; new system installations take 3–5 days.
Installation
Our engineers carry out the work neatly, taking care with pipe routing and protecting floors and furniture throughout.
System Commissioning and Balancing
A properly commissioned central heating system is balanced — each radiator is adjusted to receive the correct proportion of heat output. We purge trapped air, add inhibitor, and set up all controls.
Handover
We demonstrate the system, explain how to operate new thermostats or zone controls, and leave all Gas Safe documentation and warranty information.
Central Heating for Erith Properties
Victorian and Edwardian Terraces
Older Erith properties with small-bore original pipework can cause flow restrictions when more powerful modern boilers are installed. We assess pipework sizing during the survey and advise on any upgrades required. Original radiators in these properties are often undersized for modern comfort expectations.
Post-War Semis (Northumberland Heath)
Many of these properties still have gravity-fed open-vented systems with header tanks in the loft and hot water cylinders in airing cupboards. Converting to a sealed pressurised system is one of the most effective heating upgrades we carry out in DA8, dramatically improving efficiency and hot water pressure.
Newer and Riverside Properties
Properties built in the last 15–20 years typically have modern combi-based systems. Annual inhibitor top-up — which many homeowners are unaware is needed — is straightforward maintenance we include during annual boiler services. Magnetic filter servicing is also important from around 5 years.
FAQs: Central Heating in Erith
How much does a powerflush cost in Erith?
A powerflush for a typical Erith home (8–12 radiators) costs from £350–£500 including inhibitor dosing and magnetic filter installation. We provide a fixed quote after inspecting the system.
My radiators are cold at the bottom — do I need a powerflush?
Cold spots at the bottom of radiators are a reliable sign of sludge accumulation. A powerflush typically resolves this. Signs that confirm it include dark water when bleeding radiators and a boiler that makes kettling or rumbling sounds.
Can you add a radiator to my loft conversion in Erith?
Yes — this is straightforward in most cases. We connect the new radiator into the existing heating circuit, size it correctly for the room's heat loss, and fit TRVs for individual room control. We confirm feasibility during the free assessment.
