Thank you for your enquiry.

The Henley Sherwood 21kW boiler stove provides up to 13kW to water, which can potentially run around 14 radiators and hot water, depending on your system size, insulation, and overall heat demand. The exact suitability will depend on how your heating system is configured. We’d always recommend having your installer carry out a full heat-load and system test to confirm it’s the right match for your property.
