I recommend 2 things..With the price of gas going nuts im going to sweep the chimney this week and start using the fire in the dining room, which I haven't done for a few years. I may get a heater like that for the bedroom.
To be fair the price of gas could rise tenfold and I could atill well afford it, but the I see it the less pennies in someone elses account and the more in mine the better.
1. Not sure its still legal but get a brush and shove miniD up the chimney

2. I recommend this tower heater. So quiet but very effective.
