Slight problem re heating & hot water if you can help?

[gilford]

Quick question if you can help please.........

I have got a really old boiler, hot water tank, gravity fed system.

If I have the heating come on on its own the house is lovely and toastie, if I set the water to come on on its own it heats up the tank in half an hour, but if I have both come on together then I have luke warm rads and luke warm water?

I have got my pump on number 3, the tank stat at 65 degrees, what is going wrong? Is it just becuase I have an old system?

I hasn't been an issue since we moved in a couple of years ago, but we have had our first child recently and as I'm sure you can imagine heating and hot water is imperative now

Cheers

Its an old oil boiler, I cannot find a brand on it. 10 rads fed off it and the thermo is set at 80 if I recall correctly?

Thanks for the help!
