A long-term relationship between Hamworthy Heating and Cedar Green Projects has resulted in five temporary boiler houses that can be towed to site to provide heating and hot water. These self-contained trailers are managed by Cedar Green Projects, based in West Sussex, and use equipment from Hamworthy Heating, including boilers.

Danny Bulch, a director at Cedar Green Projects, explains. ‘We first had a need for a temporary boiler house when we were refurbishing a hospital plant room last year. The project was in November, and they could not be left without heating during the switchover. From this we saw a niche in the market for this type of product, so we decided to build a fleet of temporary boiler houses.’

There are currently five trailers, and two more are being built.

Four trailers are used for heating and have a Purewell VariHeat cast-iron condensing boiler, Chesil pressurisation unit and Burstock expansion vessel from Hamworthy Heating.

The fifth trailer provides hot water using a Hamworthy Dorchester water heater that can run on gas, LPG or electric immersion heaters, depending on what is available. There is also a storage tank and expansion vessel.

On the choice of Purewell cast-iron boilers, Danny Bulch, says, ‘The Purewell VariHeat boiler was perfect for this as the majority of time it will be installed on old, dirty systems. The large waterways in the cast-iron boiler make it particularly robust and able to deal with debris running through the heat exchanger from older heating circuits.’
