Gwalia Housing Scheme, Carmarthenshire

The large scheme involves 3 Biotech 100 KW wood pellet boilers running in “cascade mode” for a significant residential RSL scheme of 44 units plus communal areas. This energy centre will also include PV’s, solar thermal panels and is in essence a district heating system.

The boilers use a single-phase electrical supply; have fully automated pellet feed, ash cleaning and heat exchanger cleaning. The boilers have BCL modems providing SMS messages to maintenance staff and the boilers functioning can be interrogated via SMS text messaging.

With 96% efficiency the boilers provide a low cost space heating and hot water supply to the facility.

Boilers linked to 5000 Lit buffer tank.
