What sort of shower can I run off my combi boiler?

Combi boilers produce hot water at mains pressure, which means they are compatible to either a mains pressure balanced or thermostatically controlled shower. In contrast, when a regular boiler and cylinder is replaced with a combi boiler, any existing shower should be examined for suitability. This might be a pump assisted power shower, for example, designed for low-pressure systems.

Please seek specialist advice from your boiler installer on the correct shower selection.
