Unvented Cylinder Installation and Servicing in Staple Hill

Unvented cylinder installation and servicing in Staple Hill from Dynamic Bathrooms. We are G3 registered, so new installations, annual services and safety checks are all covered.

Why Unvented Cylinders Need G3 Qualified Work

An unvented cylinder holds hot water under mains pressure, so it carries safety valves and an expansion vessel to control it. Working on one without the G3 qualification is unsafe and against building regulations. We hold G3, so installation and servicing are both covered.

What an Annual Service Checks

The expansion vessel charge, the pressure reducing valve, the temperature and pressure relief valve, the tundish and the discharge pipe all get checked and tested. Any of them failing quietly turns into a leak or a scalding risk, which is why the check is yearly.

Sizing a Cylinder for Your Household

Cylinder size comes down to how many bathrooms you have and when people use them. Too small and the hot water runs out mid shower. Too big and you pay to heat water nobody uses. We look at the household rather than guessing from the floor area.

Frequently Asked Questions

How often should an unvented cylinder be serviced in Staple Hill?

Once a year. The service checks the expansion vessel, the pressure reducing valve, the relief valves and the discharge pipe. Missing it can void the manufacturer warranty and lets small faults become leaks. We are G3 registered and can service any make.

What is the tundish under my cylinder for?

It is the visible gap in the discharge pipe that shows when a safety valve has released. If you ever see water running through it, something has let go and the cylinder needs looking at. It is not a fault to ignore, so call us if you see water there.

Can I switch from a vented cylinder to an unvented one?

Usually yes, if your incoming mains flow and pressure are good enough. That is the first thing we test, because an unvented cylinder only performs as well as the mains feeding it. If the mains are weak, we will say so rather than fitting something that disappoints.
