In the spring of 2015 we installed two 96kW Angus Super gasification log boilers, which supply heat to two 5000L Akva accumulator tanks. This allows us to produce enough heat to heat a workshop, storeroom, farm office, staff toilet, the farmhouse as well as the underfloor heating in the Byre section of the events venue.
The Eco Angus range of boilers have great track record, are very efficient and robust. They have a minimal ash output and are therefore easy to clean and maintain. Overall they require very little maintenance and are very reliable.
We burn softwood in the boilers, which is bought in as a raw material and processed on the farm into logs approximately 50cm in length. We have a contractor who comes in to process the wood for us, which is much more cost effective and time saving than us trying to do it ourselves. They are able to process 50 tonnes in approximately 15 hours. It was estimated at the outset that we would use in the region of 95 tonnes of wood per year, we are using more than that. Ideally the moisture content of the wood needs to be between 15-20%.
The system is labour intensive but works for us, we manage between us to make sure that the wood is sourced regularly, processed and the boilers stoked. It’s a simple system, which works well.
