Im going to view a house soon, the condition of the heating system is
unknown, could anyone give me some pointers on what to look for???

You could start by asking the present occupiers -- they
might even tell you it doesn't work stright off.

Ask to see it working (even if it's a hot day outside
and you have to turn up the stat to get heating on),
and check the radiators heat up as you view the rest of
the house. Check you get hot water out of the taps in
one or two of the rooms with sinks. Might want to try
running the shower too, to make sure it works and doesn't
just dribble a feeble trickle.

Make a note of the manufacturer and model of the boiler,
and come back here with that info, where someone will
probably be able to give a general thumbs up or down on
that model, and a clue how old it might be. If the boiler
is less than around 5 years old, there should be a Benchmark
logbook with the installation/service history inside it;
ask to see that.

If you've done all that, you've done much more than is
covered by any full survey. Ultimately, you're never
going to know how good it is until you're indoors when
it's -10 outside.
