Further Information- information - Boiler outputs for Country 16b woodburner & multi-fuel versions

Both wood-burning and multi-fuel versions of the Country 16b conform and are tested to EN13240. This standard requires that the test fuels are specified and outputs are published on this basis. The re-loading period can also be chosen. At Charnwood we have always believed in using realistic reloading times so that our stated outputs are easily achievable – for coal and smokeless fuel products we use 4 hours and for wood 1.5 hours.

The size of the boiler for both versions of the Country 16b is the same; however different fuels under EN13240 test conditions give different results as detailed in the chart below:

The burning performance of wood differs over time compared to that of coal based fuels (see graphs), therefore when burning wood we recommend that a figure of 10kW is used to size the system, while the stated 12kW figure should be used for coal based fuels.

Of course in practice re-loading cycles and system loadings vary. If the boiler is loaded more often then the output will increase. Therefore when sizing your boiler great care should be taken and all information on the performance of different fuels and conditions should be taken into account, which your HETAS registered solid-fuel heating engineer should be able to advise you on.
