A Greener Alternative were called in to design and install a system that could utilise access so the homeowners could 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.

This property had access to woodland and logs, which meant a log boiler was the obvious choice, due to minimal fuel costs and sustainable carbon neutral credentials. However the property had no usable internal space for an internal log boiler and thermal store. So we decided to overcome the issue by utilising the outside space and installing an external log boiler. The perfect solution was to use a 45kW Central E-Classic outdoor log boiler, due to its weather proofing and stand –alone design providing a flexible location for the installation.
The advantage to using this type of log boiler, is essentially all components are housed within the boiler as pictured, which offers a compact solution to log burning. The Central E-Classic has an integrated thermal jacket, which means there is no need for a thermal store. The boiler is connected to the internal heating connection via an insulated pipe running over ground, however in many installations we run insulated underground piping.
The E-Classic requires a manual load and can take logs of up to of 750mm in length. A full load will typically produce enough heat and hot water demands for 4-5 days in the summer and 2-3 days in the winter. The Central requires cleaning once every 6-7 weeks.
The end result of the installation provides a fuss free biomass option, which has no impact on the internal spacing with a home. The boiler can be located anywhere outdoors so provides a flexible solution to log burning for hot water and heating.

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.
