MHG Heating’s new Low NOx (Class 5) Wallcon wall-mounted gas-fired condensing boilers are available in 115kW, 125kW and 160kW capacities, with the ability to combine up to 16 units in cascade configuration. Further flexibility is provided by a fully modulating pre-mix burner with 4:1 turndown capability for the 115kW model, and 7:1 for other models.
Wallcon boilers are available with matched mounting frames and cascade hydraulics including low loss headers or matched system separation plate heat exchangers. The latter are ideal for maintaining separation between the new boiler and an older distribution system, thereby protecting it from contaminants in the pipework.
The MHG Wallcon range features built-in frost protection and time control, with direct BMS connectivity and remote monitoring options using either the internet or GSM network. Other features include an integral pump with anti-seize program.
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.
