Ross Home and Hospital

Replacement of LPG heating with wood chip fuelled heating.
Description of facility: 

The new wood chip boiler is a 300kW Pyrot 300 round combustion chamber with moving grate system, made by the KOB Viessmann Group. The maximum boiler temperature is 95oC with a continuous heat output of 270kW.
The boiler provides hot water via the low temperature hot water (LTHW) primary circuit to the accumulator tank.
The heat from the 2000L custom-made accumulator tank is transferred to the domestic hot water calorifiers via LTHW pipe work. A heat meter measures the energy usage, and Spark Energy was able to use the existing pipe work and
radiators from the LPG system.
The wood chip fuel is supplied by H A Foote Haulage.
