Hunter herald 8 flat top stove is an 11KW stove, designed to heat the medium sized room. The Herald 8 is a workhorse of a stove made here in the UK. There are boiler options if you want to link the stove to your heating and hot water system, and there is an optional fire screen which lets you burn with the doors open (which is cosy but not an efficient way to burn really).
