Three separate circuits from new Hamworthy wall-hung boilers

Milborne
For maximum flexibility, Hamworthy Heating’s Milborne 502 condensing boiler has two 50 kW heat exchangers to give a total capacity of 100 kW in a single casing.
The Milborne 500 range of wall-hung modular condensing boilers from Hamworthy Heating has modulating outputs from 15 to 50 kW and 15 to 100 kW. Emissions are less than 20 ppm (18 to 36 mg/kWh). The smaller boiler has a single bi-metallic heat exchanger with copper inside and stainless steel outside. The larger model has two 50 kW heat exchangers, with a maximum working pressure of 6 bar. The high efficiency of these boilers enables flue-gas temperatures to be just 5 K above the return-water temperature, so that the boiler can use a 50 mm-diameter plastic-flue system. Boilers can be room sealed, so that they can be located almost anywhere. Milborne boilers use a simple master and slave system to manage multiple boilers, with each model supplied with a master or slave control. Sequencing is controlled according to heat-load requirements. Up to three independent heating circuits can be controlled — such as a calorifier for DHW, high-temperature circuit for radiators or fan-coil unit and low-temperature circuit for underfloor heating.
