If you do have an open fire however, here are some tips to get the most heat out of it.
Find a good wood supplier. Young green wood contains about half a litre of water for every kilo of timber. That is the spitting noise you hear when it burns, so effectively you are burning water. If you love your wood fire, one of the best ways to make it more efficient is to put a heating system like a fire management insert into your fireplace. A heating system will improve heating efficiency by around 5 times and will make your fireplace a lot safer.
If you have had enough of wood deliveries, splitting wood and scooping out ash, you might consider a gas burning insert for your fireplace. There are a number of extremely efficient faux fire versions and some excellent modern inserts as well. You can set temperatures, timers to light and all have built in fans that push the warm air out into your room.
