Hot water/Heating problem! :(

[stokieah]

When I turn my hot water on nothing happens....the only way iI can get the water to heat up is to have the central heating on at the same time, which as you can imagine is both expensive and also makes the house hot when all we want is a hot bath!
Can anyone offer any words of advice? Is just switching on the immersion heater in the airing cupboard the only answer and is this much more expensive than my current option?
Any advice would be glady received - Thank you.

The boiler is an old Gloworm Hideaway (i think its a 50 or 70 model). It was serviced last month and found to be in good working order, but I forgot to ask the engineer about this problem. Sorry, that's about all I know about it.

No water at all, or no hot water?
It would help if you made the effort to describe exactly what the problems is and what your installation consists off.

I'm guessing the 3 port valve is stuck.
