The Ecompact 150 is a wood pellet utility boiler designed to be installed in a utility room, garage, or outbuilding. It has an output of up to 14.6kW, but can of course adjust downwards when less heat is needed. The internal pellet hopper is filled by hand, or you can add on a vacuum feed system connecting to a large external hopper if you would like to automate things. 

14.6/18.2/23.3 and 26.8kW outputs available
