Common Questions — Water Heater Installation in Greenwich

What is the difference between vented and unvented water heaters in Greenwich?

Vented systems in Greenwich are gravity-fed from a cold water tank in the loft and deliver lower water pressure. Unvented systems connect directly to the mains and deliver full mains pressure to all outlets. Unvented systems require more space and G3-qualified engineers — but the performance improvement is significant.

Can you install a Megaflo in my Greenwich property?

Yes. Our G3-qualified engineers install and commission Megaflo unvented cylinders (and equivalent brands) across Greenwich. We assess your incoming mains pressure and flow rate first — if the mains can't support the cylinder, we'll advise alternatives.

How much does a new hot water cylinder cost in Greenwich?

A vented cylinder replacement in Greenwich starts from £800 installed. A new unvented Megaflo installation typically costs £1,500–£2,500 depending on cylinder capacity and any pipework changes required. We provide a fixed quote before starting.
