My boiler is showing no pressure on the guage and if i try to bleed the rads up stairs there is no water or air coming out. Also if i try to switch the boiler on the fan runs to purge the system and the pump runs, but there is no heat or hot water. The main burner will not light, I believe this is due to the lack of water pressure in the system but there is very good water pressure to the house. We have recently moved into this house which was empty for some time. Before the system stopped working all together it would make a whining noise for about 5 mins after start up and when called to provide hot water.
thanks

under your boiler should be a flexi braided hose with a tap on it open the tap that will fill the system with water, watch the gauge and fill to 1.5 bar then shut tap. then you need to bleed rads but keep checking your gauge and keep pressure up to 1.5 bar.
