Neuadd Farm Cottages
A Baxi Solo Innova 50 wood boiler coupled with four solar manifolds with twenty two evacuated tubes each. Supplies heat to a 3000 litre cylinder, this heat store feeds a great main distributing to nine holiday cottages, each of which has underfloor heating a small radiator circuit and mains pressure hot water. There is an immersion heater in each cottage as backup. As this heated water is pumped round the cottages on demand, indicator lights in the boiler room show whether heating or hot water is being called for and from where.
Other provisions in the boiler room are;
- a high limit thermostat on the cylinder will circulate water round the heat main. This extra 200 litres is intended to cope with possible over production from the solar panels. It has a yellow indicator light on the control board.
- A low limit thermostat on the cylinder which prevents any demand from switching on the pumps. This allows for faster heating recovery and has a yellow indicator light on the control board.
- Within the control box there are three 6a. Circuit breakers. Two of them isolate the cottages and are in groups 1-4 and 5-9. The third isolates the boiler and its controls. This means that the boiler can be fired independently if needed or with just one group of cottages.
- Within the control box there are two 2a circuit breakers which isolate the pump sets. Using these one or two can be selected to match the load of occupation or in the event of a breakdown, the faulty one switches off and the system will still function.
- As mentioned above the demand from each cottage is indicated on the control panel. A blue light for DHW and red for heating and these show against the cottage number.

- 90% reduction of heating costs
- Collar input reduced refuelling cycles on boiler
CONS:
