Kingscote Vineyard

Fuel Saving over 20 years: £238,677
RHI Payment over 20 years: £264,101

Set in a rural location, the Kingscote Vineyard required a heat source which would provide constant heat to a period barn, which has a large heat load. Under floor heating was chosen for this beautiful 17th century barn, as it solved all aesthetic issues and provided a constant heat source even when the barn doors are open. Due to the large heat load a pellet boiler was chosen due to its high calorific heat source.

This project required A Greener Alternative to install a Froling 85kW pellet boiler into a small barn which would act as an energy centre and pellet store. The boiler would feed underfloor heating to the magnificent 17th century barn which had been relocated piece by piece to form the centre point for the vineyard.

National Trust

Fuel Saving over 7 years: £14,083
RHI Payment over 7 years: £26,175

This national trust property wanted to make use of various forms of sustainable energy. The Property had a south facing pitched roof and was set in densely populated woodland. Therefore it was decided that a combination of thermal solar, log boiler and log stove would be used to harness the carbon neutral assets surrounding the home and produce the heating and hot water for this unique ecological home.

A Greener Alternative worked with the national trust to create a bespoke system which would be perfectly balanced for the needs of this unique building. The use of multiple ecological technologies demonstrates the skills required to create a fully sustainable and efficient system.

The boiler is a 28kW froling log boiler and was housed in the utility section of the house with buffer tank. The solar thermal are a combination of flat plates and tubes. The log burning stove is not connected to the hot water system and provides room heat only.

Colchester Zoo

Fuel Saving over 20 years: £195,593
RHI Payment over 20 years: £621,415

Colchester zoo has a dedication to the environment and conservation, so it was an obvious choice to convert to using biomass, as it would solve both high fuel bills and create a carbon neutral heat solution. The premises is a large Victorian period building and required a significant heat load with an efficient calorific fuel source, therefore a pellet boiler was chosen for the project.

A Greener Alternative fitted a 200kW wood pellet boiler to provide hot water and heating to the main building. As you can see from the photo’s access was difficult, but not an impossible task with the use of a crane.

The boiler, hopper and buffer tanks are situated in a container unit turned energy centre. The installation also has a steel framed external 7 ton pellet store. The system is fully automated and pellets are blown delivered.
