The challenge

The estate's existing setup — mixed oil and LPG across three buildings plus dedicated grain drying diesel — was expensive, complex and inefficient. The owners wanted one heat source, reliable grain drying and RHI income where available.

Our solution

200 kW Hargassner ECO-PK pellet boiler sited in a purpose-built plant room, with a 25-tonne bulk pellet store served by blown delivery from Land Energy. Pre-insulated district runs to the farmhouse and two cottages plus a heat exchanger feeding the grain drying rig during harvest.

The installation

Installed over three weeks with the pellet store and plant room built in parallel by the estate's own builders under our direction. Commissioning included full-load testing into the grain drying circuit during an August harvest.

The outcome

£18,000
Annual Fuel Saving
£14,000
RHI Annual Income
92% vs oil/LPG
Carbon Reduction
99.9%

★★★★★
Harvest is the deciding test — and it's worked perfectly two years running. Highly recommended.
