Our Work in Kemsing

We recently installed an unvented hot water cylinder for a homeowner in Kemsing — upgrading from an old vented cylinder in the airing cupboard to a modern pressurised system that delivers mains-pressure hot water to every tap and shower in the house. The difference in shower performance alone made it immediately worthwhile for the family.

Kemsing's housing stock includes a number of larger detached homes where a combi boiler isn't always the right answer — particularly where there's high simultaneous demand for hot water from multiple bathrooms. An unvented cylinder paired with a system boiler gives you the best of both worlds: mains-pressure hot water and a boiler that isn't struggling to keep up. Unvented work is specialist — it requires G3 qualification in addition to Gas Safe registration, which we hold. If you're considering an upgrade in Kemsing or the surrounding TN15 area, we're happy to advise on the right setup for your home.

Frequently Asked Questions

Common questions from homeowners in Kemsing and nearby villages.

What's the difference between a vented and unvented hot water cylinder?

A vented cylinder relies on a cold water tank in the loft and delivers hot water at low pressure. An unvented cylinder connects directly to the mains supply, giving you high-pressure hot water at every outlet — much better for showers and homes with multiple bathrooms. Unvented systems must be installed by a G3-qualified engineer, which HeatCool is.

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.

Do you cover villages near Kemsing?

Yes — as well as Kemsing we cover Otford, Sevenoaks & Borough Green, Borough Green, Sevenoaks, Tonbridge and the surrounding Kent postcodes. Call us to check if we cover your exact postcode.

How much does a new boiler cost in Kemsing?

Unvented cylinder installation typically starts from £1,200–£1,800 depending on cylinder size and the complexity of the pipework. A new combi boiler starts from around £1,800 fully installed. We provide fixed written quotes before starting.

Do you offer same-day callouts?

We offer same-day availability subject to capacity. For urgent boiler breakdowns in Kemsing, call us on 07415 078644 and we'll do our best to get to you the same day.
