Hi all, boiler pressure generally fine through the summer for hot water use. Now I have used for central heating it constantly drops in pressure. I crank the pressure up but within hours its to 0 again. Any advice?

check the prv pipe outside first 
and watch the pressure when heating is running

thats where your pressure is going then
prv needs replacing / cleaning
poss expansion vessel needs recharging or at least checking
