CaseStudy


Allenbourn Middle School’s old heating plant (three condensing boilers from ca. 1994) were getting old and unreliable. At the start of the September school term one boiler broke down with another partly working and the third running normally. Shortly after, the second boiler broke down and as spare parts for repairs were no longer available, the urgent replacement was identified and found. Local contractor Giles Heating working with


Hamworthy Heating (both based in Poole) helped the school keep its students warm and happy over the winter during and after the refurbishment. Coomber Associates was appointed to undertake the design, tendering, health & safety and contract administration of the replacement boiler plant. They had previously worked on several other capital projects with the Wimborne Academy Trust which looks after the school. The project was completed over the winter


months and to maintain heat in the school, a temporary mobile boiler plant was required. A trailer with two of Hamworthy’s Stratton mk2 S2-150 wall hung boilers was provided by Giles Heating with the mobile plant room providing heat for the three-week period when the replacement of the old boilers took place. Other than the temporary plant, the difficulty of


the project was to find boilers that would suit an old system and be compatible with the existing pipework. Fortunately, the Hamworthy Purewell Variheat mk2 cast iron condensing boilers fitted the bill with a similar footprint as the old boilers to sit on the same plinths. The cast iron heat exchanger with 10-year


warranty and large waterways deals well with existing debris in older heating systems. The three boilers deliver an output of up to 285kW (50°/30°C) and can match the heat demand with a turndown ratio of 9:1.

“Previous excellent customer service, meant we had no reservations about specifying a Hamworthy product.” Oliver Coomber, Coomber Associates


Oliver Coomber, director at Coomber Associates, who looked after the project commented: “Being a company local to the site with previous excellent customer service, we had no reservations about specifying a Hamworthy product to be installed. The appointed contractor, Giles Heating, used their own temporary boiler plant to complete the replacement to a high standard and within the timescale required. The newly installed boilers were handed back to the client within the programme period and under the original budget. We are very satisfied.” Visit www.hamworthy-heating.com, call 01202 662500, or email sales@hamworthy-heating.com.
