Hi,
Just replaced my 20 years old Vaillant boiler with a Alpha E-tec 20S; all went smooth with chemical flush etc on the day. Didn't have any issues with heating but when taking shower first time water started to get luckwarm and cold at the end of 20 mins or so. Also another issue I have noticed is it hot water is a bit delayed ( 4-5 seconds ) when opening at taps either in bathroom or kitchen. Called the company who installed the boiler and they think it is airlock in the system. Can anyone has any ideas what is causing this as didn't have the same issue before with the old boiler. Thanks a lot.
