Full commissioning, test records and Building Regulations notification (where required) are completed and handed to you, plus our one-year workmanship guarantee.

BENEFITS

Why Choose us for Hot Water Cylinders?

True mains-pressure performance

Unvented cylinders deliver powerful showers and steady flow to multiple outlets without pumps — ideal for homes with more than one bathroom.

G3-qualified engineers & OFTEC/Gas Safe coverage

All installs are carried out by G3-qualified staff; Gas Safe and OFTEC registrations mean we can work on both gas and oil-fed systems common in rural Kent.

Certified, backed work

Every installation is fully commissioned to Building Regulations, supplied with paperwork and a one-year workmanship guarantee for peace of mind.

What we fit We supply and install modern unvented (G3) hot water cylinders and compatible indirect cylinders with high‑grade pressure relief valves, expansion vessels and insulation. These systems remove the need for a loft cold tank, freeing up space and reducing frost and tank‑maintenance risks. Engineers size cylinders to the property and the connected boiler — our Worcester Bosch accreditation helps when matching controls on compatible boilers.

FAQ

Frequently Asked Questions

What is the difference between vented and unvented cylinders?

Vented systems use a cold water tank in the loft and rely on gravity, giving lower pressure. Unvented (G3) cylinders connect to the mains and provide mains‑pressure hot water to showers and multiple outlets. Unvented systems require a G3-qualified installer and pressure safety devices.

Do you handle installations for oil‑heated properties?

Yes. Pro Plumbers Ltd is OFTEC registered and experienced with oil-fed systems common in rural Kent. We size and configure the cylinder to work with your oil boiler and controls, ensuring correct expansion and safety measures are in place.

Will I get certification after installation?

Every unvented cylinder installation is fully commissioned and supplied with Building Regulations paperwork and test records. You will receive certification and a handover pack detailing maintenance and the one‑year workmanship guarantee.

How disruptive is an install?

For standard cylinder replacements we aim to complete work efficiently with minimal disruption, often in a single visit. Larger installations or conversions may need extra pipework or tank removal; we outline access needs and timescales during the initial survey.

What maintenance does an unvented cylinder need?

Unvented systems need periodic inspection of safety devices, an annual service of the associated boiler and checks on expansion vessels and relief valves. We offer servicing and planned maintenance to keep the system working reliably.
