hi..i have some serious problems with my heating system. i have a valliant boiler for my flat which supports 5 radiators..i hear loud noise of water rushing through the radiators whenever i switch the boiler on..i tried bleeding the radiators(done a mistake by bleeding them with boiler on). while bleeding i heard hissing sound for 2 minutes, but no water came out after the hissing stopped. i tried bleeding it again after 2 days..and again i heard hissing sound of air for 2 min and no water came out..every day i have to bleed them to heat the radiators to the top. and also the radiators stop from heating all of a sudden and my boilers switch of automatically. also im not so sure of the controls on my boiler since i dont have a manual..Also the water from the tap takes too long to heat and stops suddenly and i have to switch on the boiler again to get some hot water..can u please help me out with my problem??..thanks
