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.
