Ty Penrhos, one of Hafod Care’s newer care homes in Caerphilly, which specialises in dementia care, benefits from two forms of renewable energy supplied by Baxi Commercial. The mini-CHP unit from Baxi-SenerTec UK generates electricity whilst also producing useful heat, and a solar water heating system from Andrews Water Heaters is used to pre-heat domestic hot water generation.
Ty Penrhos is a three storey purpose-built care home providing accommodation for 75 residents with high care dependency and, as such, the building has a particularly high demand for both heat and power 24/7.
The building services were designed by McCann & Partners in accordance with Hafod Care’s requirement for the use of renewable energy systems and the equipment supplied by Baxi Commercial was deemed the most appropriate system. Both Baxi-SenerTec Dachs gas-fired mini-CHP units act as lead boilers for the space heating system and each has an electrical output of 5.5kW and a minimum heat output of 12.5kW.
Using an optional condenser, the Dachs unit is capable of producing up to 15.5kW of heat. In installations where heat demand is unreliable, use of a buffer vessel can keep the unit running and maintain the electricity supply.
