BTU p/h calculators are brilliant for the
consumer. They allow us to calculate roughly how much heat output our radiators
need to provide in order to maintain a specific temperature. However, it’s
important that you understand the following two concerns when using a BTU p/h.
If you do not address these concerns
correctly, then you can end up with estimates that are widely inaccurate. In
turn, this can mean that you buy the wrong radiator for the room, which in turn
can prove costly in terms of your energy bills.
1.
You must provide accurate dimensions
The first thing that you
need to bear in mind is the exact measurement of the room. Do not use a BTU calculator and just guess the
figures. Unless you're lucky, or you have an unbelievable eye for measurements,
then you are highly likely to get it wrong. If you get it wrong, the BTU p/h
calculator will return an inaccurate result.
When taking your
measurements, take the length, height, and width of the room. You should have
three measurements.
NB: make sure that you are
using the correct measurement system. Double check to make sure that you and
the BTU p/h calculator are using either the metric system or the imperial
system.
2.
You must make allowances for insulation differences between the room
and the variables on the calculator
While a BTU calculator will usually make some allowances for these
differences – for example, they’ll ask which room the radiator is to go in,
they don’t necessarily make enough allowance. For example, in a room that has
triple glazing and cavity wall insulation, you will need around 10% fewer BTU
p/h to keep the room warm than a double glazed non-cavity wall insulated room.
Now that you understand a bit more about
the considerations you should be taking when using a BTU p/h calculator, you
should be able to get a much more accurate reading. If you have any questions
