In a larger Dore property with several bathrooms, a system boiler with a properly sized unvented cylinder is usually the better answer. A combi heats water on demand from the mains, so running two showers at once tends to drop the flow at both. A stored-hot-water system gives you full flow from several outlets at the same time. We'll measure your incoming mains flow and pressure and size the cylinder to how your household actually uses hot water.

Unvented hot water cylinders are pressurised, so they must be installed and serviced by someone holding the relevant unvented systems qualification, and they need an annual service to stay safe and keep the manufacturer's warranty valid. The install also needs a suitable discharge route for the safety valves and enough mains flow to be worth doing — all things we check at survey.

It can affect anything visible from outside — a new flue position, external pipework or an outdoor unit, for example. The Dore Conservation Area was designated in 1971 and covers the historic core of the village. We plan installations to keep external changes as discreet as possible, and where a job may need consent we'll flag it early rather than after the work has started. Any formal planning or listed building approval is a matter for Sheffield City Council.

In larger properties it is very often a balancing and sizing issue rather than a broken boiler. Long pipe runs to rooms at the far end of the house, radiators undersized for the room, or extensions added onto a system that was never re-designed will all leave cold spots. We survey the whole system, calculate what each room actually needs and rebalance or resize accordingly.
