Heatpump Heat / Chill has a sizeable projected income and savings with the 20 year Government Tariff

“We commissioned Calibrate to design and install the system that suited our heat and cooling requirements within our business. The project has progressed efficiently and is now complete and in full operation. The installation process ran smoothly with good communication and work quality from Calibrate staff and engineers. We look forward to the overall benefits of the project.”

Intelligent Hands Off Heatpump Systems

The Introduction.

David and Peter Allan (RH & DH Allan) farm 2400 acres of arable land in the Scottish Borders growing a variety of commodities including; potatoes, swede, grain and oil seed rape. The installation of a 1996kw Ground Source Heatpump has enabled the business to reduce fossil fuel expenditure, increase efficiency of the existing business and also benefit from the 20 year RHI scheme.

The Process.

Having designed the system with the client to ensure it was best suited to the individual needs of their business. 34,000m of underground pipe takes the heat that is naturally occurring in the ground and multiplies that through the Heatpump. Using a mixture of Heat Exchangers and Plate Exchangers, hot air and hot water is provided through a fully automated system. The pre heated air is directed into the grain dryer, drying floor and workshops. The hot water used for cleaning equipment provides 100% fossil fuel replacement all whilst also benefiting from the RHI scheme. This enables the client to maximise his cost savings by utilising the free by-product, chilling, to satisfy 80% of the chill load in the cold stores using a non-toxic glycol system.

The Figures.

  • 4 year pay back
  • 35°c at 350% heating efficiency
  • 1°c at 300% chilling efficiency
  • Total energy efficiency of 650%

The Conclusion.

By using Calibrate’s site specific control system we are able to provide an efficient and effective solution to the carbon foot print and cost benefit to your existing system whilst also providing expansion options into the future. The exclusive Calibrate 20yr maintenance and extended warranty package means that there are no unexpected expenditure for the lifetime of the tariff.

Demand Side Response (DSR)

DSR financially incentivises energy users to increase or reduce on demand nonessential energy usage at times of peak or low demand.

Why is demand response needed?

The National Grid has to maintain a certain level of energy production capacity above actual demand. DSR is designed to provide the margin, either by increasing or decreasing site energy use.

What are the benefits of demand side response to you?

The primary business arguments for DSR are financial renumeration and sustainability. DSR not only allows businesses to avoid higher energy prices and receive renumeration during times on and off peak demand.
