my pressurised heating system keeps losing pressure there are no sign of leeks from the pressure tank or radiators. It is run by oil and i have to keep topping up the system 3 or 4 tomes a day what could the problem be.
you need to check your pressure vessel is at around 2 bar as if it is empty then the hot water has no where to expand so its probably discharging from the blowoff.
