Our Work in Aylesford

We recently attended an unvented hot water cylinder repair in Aylesford — the homeowner had lost all hot water pressure after a pressure relief valve failed and discharged. We diagnosed the fault, replaced the faulty valve and expansion vessel, and restored the system to full working order the same day. Unvented cylinder faults can seem alarming but are usually straightforward to resolve when you have the right G3-qualified engineer.

Aylesford has a mix of newer estates and older village properties, and unvented cylinders are increasingly common across both — particularly in homes that have upgraded from older vented systems for better shower pressure. These systems require a G3-qualified engineer for any repair or servicing work, not just installation. If your unvented cylinder is losing pressure, discharging water from the tundish, or simply not performing as it should, get in touch — we carry common replacement parts and can usually resolve the issue on a single visit.

Frequently Asked Questions

Common questions from homeowners in Aylesford and nearby.

Why is my unvented cylinder losing pressure or discharging water?

The most common causes are a failed or correctly-operating pressure relief valve, a waterlogged expansion vessel, or an overheat situation. A discharging PRV should always be investigated promptly — it's the system protecting itself. Call us and we can diagnose and fix it, usually on the same visit.

Are you Gas Safe registered?

Yes — HeatCool is Gas Safe registered (no. 938735). You can verify this on the Gas Safe Register website. It's a legal requirement for any gas boiler work, so always ask to see the card before an engineer starts.

Yes — as well as Aylesford we cover Larkfield, Kings Hill & West Malling, Sevenoaks, Borough Green, Tonbridge and the surrounding Kent postcodes. Call us to confirm we cover your exact area.

How much does a new boiler cost in Aylesford?

Do you offer same-day callouts?
