OK so its deepest darkest February and the weather this year is even worse than normal. So it’s a good time for us to release an article on heating. Did you know there is a system to calculate how much heat a room needs? Its called a BTU or British Thermal Unit. Once you have calcualted a rooms BTU you can easily work out what size of heater(s) you need. This means you won’t waste money over heating a room or put in a heater that can’t do the job.
While researching this we found this diagram on the Bath Empire blog. They said we could reprodcue it for you here – so thanks to bathempire.com for letting us have it.
