New Potterton Commercial iHE Combination Boiler

Launched in Spring 2012, the new iHE commercial combination boiler from Potterton Commercial is the only one of its type on the UK market, producing space heating and hot water from a single generator and a tank, both enclosed within one cabinet. The condensing heat engines with premix modulating gas burners, achieve 96% gross efficiency and heat hot water via stainless steel heat exchangers. The appliances are room sealed for use with either vertical or horizontal flue systems.


There are two models within the range – one incorporating two 50kW heat engine modules providing 100kW of space heating, the other having three 50kW heat engine modules, offering a space heating capability of 150kW. Both have a similar capacity stainless steel cylinder, storing 300 litres of domestic hot water, and achieve a recovery rate of 1,400 litres/hour.  In line with requirements for unvented stored water, both WRAS and G3 approvals have been applied for.


Most importantly, the iHE can integrate hot water production with solar thermal, air source and ground source heat pump technology for pre-heat, thereby minimising the input required from fossil fuels.


Again, focusing on improved efficiency, the new iHE has all the versatile control options for space heating and hot water profiles, including weather compensation with optimum stop and start, frost protection, module sequencing and load sharing.
