I've used Vauxhall's owners club forums before. Very helpful!

You'll probably find that someone somewhere has made an owners club on the tinterweb.

Generally it will be because your heater matrix is clogged up with crap.
I did this recently and it worked a treat.
Find where your heater pipes (like the black ones over your radiator) go through the bulkhead behind your engine and into the car.
Unclip or take them off the mounts so you are left with 2 holes.
Get a water hose and flush it out both ways. Make sure that you wrap some poly bag around the hose so it gets a good seal. It should flush the matrix through and kick out what looks like sludgy puddle water.
Do it a fair bit until you get clear water coming out.
The top up your coolant and run the engine without the coolant tank cap being fitted.. Give the hoses above the radiator a good squeezing to push any air through the system into the coolant tank.
Then check the coolant level and top up as needed and refit the cap.
You should have nice warm air now.
It may need doing again in a few weeks, but that should be it.

Pretend I am really thick...
What am I connecting the hose to...the engine?
Second why do I need to top up the coolant?

1) NOT TO THE ENGINE. Connect the hose to the inlet of the heater matrix, have a bucket ready to catch the mucky puddle water or let it run all over the floor turn on the water let it run clear. Then swap to the outlet of the matrix and repeat until it runs clear.
2) When you refit the hoses to the matrix they and it (the matrix) will have little or no water in them thererfore your water level in your radiator (It's all connected) will be very low so you have to fill it back up to the proper level. Fill up the rad run the car for a couple of minutes and then recheck the level in the rad it most likely will need more water.
Don't forget to add the right qty of anti-freeze

Cheers TB.
50:50 is usually a good enough mix unless you live in Greenland!
What happens over time is the coolant/water mix picks up all the sludge and crap in the system and it ends up in your heater matrix. This clogs the matrix up and lowers the flow rate through the system and thus the heating effect.
Thats why sometimes you'll need to do it once more after a week or so. Because the rest of the crap that was circulating now has some nice bits to cling to in the matrix after you flushed it.
The 2 hoses you need to undo go onto the wall (bulkhead) that divides your engine bay from your car interior. The heater matrix is usually somewhere on the passenger footwell side so the hoses are quite often on the middle to right area of the bulkhead as you look at it from the front of the car.
By sticking a hose on the inlet and outlet you flush loosen all the crap up and flush it out.
Because you have disconnected part of the system and flushed some of the fluid out you'll have to top it up. Its not usually much to be honest because the inlet/outlet is normally positioned higher than the matrix so when you flush it you leave some fluid in there.
Personally I'd get a 50/50 mix and after having topped it up whilst squeezing hoses, I'd take it for a 5 minute run.
Then just check the level again and top it up if needed.
If you feel the need you could always undo each rubber hose in there and flush all of them through. You just need to ensure that when its all back together that you run it with the coolant cap off and squeeze the biggest hoses to push any air bubbles out of the system.
Generally speaking though flushing the matrix once should make the difference.
Check your pollen filter as well. They quite often get ignored and become proper clogged up!

Jolly good. Keep an eye on it, if it starts to get cooler it might need one more go.

Can i add additional thanks Dads car has keeled with a similar problem so provided him with your instructions. I will report back soon hopefully.
