Hamworthy Heating has been at the forefront of commercial heating and hot water solutions since the 1960’s when we introduced the UK heating and hot water market to the concept of modular boilers.

Today, more and more heating specifications are opting for the replacement of old inefficient heating systems with new, fully modulating condensing boilers, not only reducing carbon emissions, but making financial savings too.

The new Fleet boiler brand exemplifies this trend and comprises an exceptionally versatile range of modular condensing boilers which are British designed and built at the Hamworthy factory in Poole.

With one unique heat exchanger design, Hamworthy has taken an innovative approach to offer Fleet in wall hung as well as floor standing configurations from one single brand.

Fleet is an advanced modular boiler design which sets new standards for delivering heat from small spaces. Using its expertise in floor standing modular boiler design, Hamworthy are able to offer the capability to place more than 1 MW on the floor in less than 1 square metre - an exceptional achievement.

Through the Hamworthy Heating Technology partnership programme, we are able to offer a whole range of renewable energy technologies for commercial heating and hot water applications. Whether it is solar thermal, heat pumps or biomass – supported by traditionally fuelled high-efficiency heating systems, for commercial applications, Hamworthy offers the widest scope.

Thousands of customers have chosen Hamworthy’s experience. Their choice delivers the performance they need, efficiency they want and the support they expect.
