MHG Heating has introduced the Ultrabox range of gas-fired condensing boilers in capacities from 210kW to 1125kW, with cascade capabilities for up to 16 units. MHG Ultrabox gas fired condensing boilers feature a fuel engineering related efficiency of up to 110% and 8:1 turndown capability and are suitable for a wide range of flow rates with low pressure drop. NOx levels are low, at 34mg/kWh.
MHG Ultrabox boilers incorporate automatic frost protection and built-in time control. Each boiler is capable of controlling up to four separate heat zones as well as domestic hot water (DHW). If required, the boilers can be interfaced to a BMS with the option of remote monitoring.
Zero side clearance means the installed footprint is up to 30% smaller than competing models, enabling optimum use of plant room space. The smallest model in the range has a footprint of just 0.72m2.
The integral safety controls, fully compliant with BS 6644: 2014, include 9 sensors monitoring the boiler’s operation every second and feeding data to 31 safety sub-systems.
All models are suitable with natural gas or LPG.
