I want to fit an outside tap on the dog run down the side of the house.
I can tap into an exsisting hot supply no problem and fit the tap. Thing is
I am getting a tap kit from B&Q will there be any problem with the fittings
they supply with it going onto the hot pipe rather than the normal cold
pipe. Its the "screw into the exsisting pipe" kind of fitting.

I specifically want a hot tap outside to wash up after the dogs and to bath
them outside. The boile doesnt kick in till the taps a quarter of the way on
anyway so even if I have a drip outside its not going to effect the boiler.

In theory what you want to do does not sound too difficult. Two possible
problems spring to mind though: Some of the garden tap kits that use a
flexible rubber hose to make the link between self cutting valve and the
outside tap, may not be rated for high temperatures. Since you have a
combi, your hot water will be at mains pressure, so it is important to
not use something that will soften significantly when hot.

The other possible problem is that you will have no real control of
temperature, other than by turning the tap on hard enough to prevent the
combi having time to heat the water too much, or by setting the limit
stat on the combi to something hand (and dog!) safe.

If it were me, I would use proper plumbing bits and not a tap kit. A
push fit tee, some pipe (plastic liek hepworth or speedfit would be
fine), a service valve, and an external tap. Chop a small section of
pipe out (having turned off the cold water valve on the inlet to the
combi, and turned the combi off). Insert the tee, pipe to a service
valve (this is so you can turn off the outside tap should you need), and
from there through a hole in the wall to a suitable outside tap. Lag well.
