Energy savings of over 27% are being achieved following the replacement of aging cast-iron boilers at the Duke of Cornwall Hotel in Plymouth with ProCon 115 condensing boilers from MHG Heating. The old boilers were proving unreliable and inefficient, so the hotel contacted Elliott Environmental Services of Yeovil for a solution.

The previous installation comprised four cast-iron boilers connected to a large fan-dilution system. There were also three old calorifiers, one of which was leaking.

The new installation comprises three ProCon 115 boilers on a rig system linked a Theta cascade control system. There are also two new 750 l packaged plate calorifiers with 154 kW plate heat exchangers to provide domestic hot water.

A plate heat exchanger separates the new plant from the old pipework to prevent damage to the new boilers. Two small chimney stacks in the boiler room were relined and used for the flue exhaust from the new boilers.
