New Build, East Sussex

  IMG_3276  IMG_3278

This eco property in East Sussex called in A Greener Alternative to design and install a ground source heat pump system to work with vertical boreholes. The boreholes were sited in the front driveway of the property during the build to minimise disruption and keep them well concealed. As you can see the 8kW NIBE heat pump is well situated in a utility room under the stairway with the hot water cylinder and buffer tank beside it, making good use of the space available.

A Greener Alternative were called in to design and install a system that could utilise access the homeowners have to their own woodland and an abundance of free fuel. The installation moved the property from its existing oil fired heating system to a state of the art Froling log boiler and buffer vessel all sited in a unique and stunning outbuilding. The services run underground back up to the property where the boiler takes care of the all the heating and hot water requirements of the home.

Retrofit, Surrey

This semi-detached property in Surrey used it’s existing oil-fired heating system to run a network of radiators throughout the house. The property owners wanted to move away from oil and A Greener Alternative designed and installed a ground source heat pump system to replace the existing set-up. Working in conjunction with two 120 metre vertical boreholes well concealed in the front lawn/driveway, the property now utilises the ground source system for all its heating and hot water requirements. The 12kW NIBE ground source heat pump can be seen here installed conveniently in the back end of the garage alongside a 300 litre hot water cylinder and 200 litre buffer tank.

Hampshire Refurbishment

This family home in Hampshire underwent a full refurbishment, with improvements to insulation and a move away from its old oil fired central heating system. A Greener Alternative designed the system and installed two 8kW NIBE air source heat pumps working in conjunction with underfloor heating, skirting heating and radiators to take on the heating and hot water requirements of the property.

Retirement Units, East Sussex

Air Source Heat Pump For Retirement Units

A Greener Alternative were asked to design and install an Air Source Heat Pump and associated components into two new build retirement units in East Sussex. The NIBE F2040 heat pump is situated on the external wall of the property and provides all the requirement for heating and hot water in the home.

With the heat pump installed the home has a highly efficient heating system and low energy consumption with the 8kW heat pump carrying an A+++ Energy Efficiency Class.

Solar thermal for heating swimming pool

The owners of this house situated in West Sussex found they were spending large amounts of money heating their outdoor swimming pool and wanted a more sustainable solution.

A Greener Alternative supplied and installed an array of solar thermal panels on the roof of the main property to take care of the heating requirements of the pool and also to supplement the hot water in the main property.

The owners now enjoy hugely reduced heating bills and a longer pool season over the summer!

Hindhead Home

KWB Easyfire domestic biomass install in Hindhead, Surrey

This install took place at a detached family home in Hindhead, Surrey where the property owners were looking to move away from their existing oil fueled heating system and expressed an interest in biomass as an alternative.

A Greener Alternative specified a 35kW KWB Easyfire pellet boiler with an 800 litre buffer vessel to take care of all the heating and hot water requirements in the family home.

Several options were discussed for a potential boiler location and the garden offered plenty of space to create a new structure to house the boiler, buffer and pellet store and the homeowners expressed an interest in pursuing this route.

A purpose built boiler room shed was constructed in the garden with enough room to house the boiler, buffer and a bespoke pellet store that was designed and constructed to fit within the shed whilst maximising pellet storage space. The Storz hose connectors can be seen at the rear of the shed where fuel delivery hoses are connected and pellets are blown into the store.

The family now enjoy a seamless changeover from their old oil system but with the benefit of lower costing, carbon neutral fuel.

Buxted Home


RHI payment over 7 years: £20,566.00

Fuel saving over 7 years: £7,472.00

This rural 4 bedroom home is a typical example of a domestic installation of a pellet fuel boiler system. The pellet fuel acts as a direct replacement to oil and behaves in the same way, with fillings simply completed by the roadside through a blown delivery. The property owners, although living rurally, do not have a lifestyle suited to using log or chip so pellet is an ideal option. The heat load of this property is typical for a property of this size and period.

A Greener Alternative fitted a 22kw KWB Easyfire pellet boiler to provide hot water and heating to the main building. As you can see from the photos, the thermal store, pellet store and boiler are all located in different sites, which is a good solution to this particular heating system, but not entirely typical.

The boiler is housed in an outbuilding, 10 metres away from the property. The pellet store is a 3.5 tonne stand alone, which is hidden away behind the outbuilding. The thermal store is located in an outside cupboard attached to the property.

Rural Farm


RHI payment over 20 years: £186,425

Fuel saving over 20 years: £185,425

This rural farm wanted to reduce their oil bills, so opted to take advantage of the government incentives by switching to biomass heating. They chose wood chip, due to the sustainable source of chip in the local area and the minimal. This site required a consistently high heat load, which is where wood chip works best.

A 110 kW Froling T4 chip boiler was selected for its clean burn and high efficiencies. The boiler house was set in a barn adjacent to the chip store. The chips were auger fed into the boiler through the adjoining wall. The thermal store is a 850L buffer and serves the farm house with hot water and heating.

Historic Sussex House


Fuel savings over 20 years: £280,796

RHI payment over 20 years: £310,710

This historic house requires a significant heat load due to the period and size of the property, therefore the occupants were spending vast amounts on heating with oil. The owners wanted to switch to biomass to reduce their effect on the environment and cut their fuel bills. A pellet boiler was selected due to its automated capability and the owner wanted a direct replacement for an oil boiler.

Two 40 kW Froling P4 pellet boilers were selected to run as a modular system. There are two buffer tanks containing 1000L each. The pellet store is a 14 tonne custom built W trough. The pellets are fed into the day hopper via suction tubes and 3 pellet moles.

The boiler house supplies a small district system including the main house via an underground pipe and a separate cottage. The boiler house and pellet store are located in a small barn/ outbuilding.
