Worcester 4000 Boiler Replacement in Horsham

A Horsham homeowner wanted to replace their existing combi boiler and three radiators. The boiler was housed in an upstairs cupboard, so the new installation needed to use the space neatly while keeping disruption to a minimum.

What the installation involved

We installed a Worcester Bosch Greenstar 4000 30 kW combi boiler, retaining the existing pipe positions where they were suitable. The cold inlet and pressure-relief pipework were corrected, a horizontal flue and Honeywell wireless room thermostat were fitted, and three radiators were replaced.

Once the installation was complete, we carried out the final gas-pressure and combustion checks and commissioned the heating, hot water and controls.

Why the survey and commissioning matter

Even when a boiler replacement looks like a straightforward swap, it still needs proper checks. Boiler output, flue route, gas supply, controls and the condition of the existing system all affect whether the new boiler will operate safely and reliably.
