MHG Heating has introduced the ProCon HTP range of gas-fired condensing boilers with integral plate heat exchangers to separate the boiler from the distribution system. As such, ProCon HTP boilers are ideal for retrofitting high-efficiency (98.1% gross seasonal efficiency) boilers to existing systems, as will be required from September 2015 for boilers below 400kW under ErP regulations for both new and existing buildings.

There are two models available; the ProCon HTP 150 comprising 2 x 75kW modules and the ProCon HTP 225 with 3 x 75kW modules. These can be combined in cascade configuration to deliver higher capacities, using fully modulating burners and integral controls to provide efficient response to varying heat loads.

The internal system separating plate heat exchanger allows the ProCon HTP to be applied to any system with operating pressures up to 10 bar without the risk that the existing distribution system will impair boiler performance. As such it enables optimum efficiency to be achieved for boiler replacement projects whilst facilitating compliance with legislation.

ProCon HTP boilers are equipped with all pressure management components other than a system pressure manager as required by BS 6644. A suitable system pressure manager is also available from MHG.

All ProCon HTP boilers are supplied with a 36 month warranty and 60 month heat exchanger warranty.
