There is usually a switch or dial on the pump itself, marked 1, 2, 3 (3
being fast) or similar. The pump may even be under the floor, in which
case don't worry unless you really suspect a problem with it.

Cheers Phil, that's very helpful advice. The pump is inside the boiler
casing according to the installation booklet, and I can't see anyway of
adjusting it so it will just have to stay as it is!!

According to http://www.partsarena.com/baxi/ you have a 'system boiler'
(ie with all/most of the peripherals like the pump contained in the
case). The pump illustration looks as though there is no speed control,
and the pump is a Myson C61 'special'. I imagine the 'special' means it
has the speed switch omitted. It is possible that the pump is controlled
by the boiler electronics instead.

As you say, leave it as is. You only need to look into it if it is too
fast; = noisy and very low temp rise across boiler, or too slow; = not
enough heat in radiators, boiler short cycles, large temp rise (well
over 11C).

I have managed to borrow an infrared thermometer..........I can't stop
playing with it - Although I can't think of a single use for one apart from
balancing radiators!!!

You can get a rough measure of your body temp by pointing it into your
ear, but clinical IR thermometers have a narrower probe to facilitate
that, and have a 3 digit display to measure to 0.1degree.

Other than that - hot food, though you really want to know the
temperature inside it. Freezer, fridge, oven (not through the glass
though).
