this doesn't seem like a radical request but I want to use the big fireplaces that I have in my house for the primary heat source so that I can discard the central heating system and especially the radiators that stop me putting furniture against the walls they blot. Coal is out - I want something that maintains the apartment heating with a thermostat - and I want it to be warm in the morning, So no coal, no coal!
I have explored flame effect gas fires but apparently no useful heat output is generated. And flueless devices, it seems cause excessive condensation.
How can I usefully use the vacant space in my big fireplaces to generate heat from a gas supply. I want the answer to be aesthetically pleasingly as well as efficient as possible.
My only other option is to install a combi heater and keep the radiators.
