Got heatline vizo 24 combi boiler only 3 year ols,had poerflush 2 weeks ago ,since last week everyday the pressure was dropping when seen next morning,so i filled the pressure from loop everyday,now since yestreday pressure dropes very rapidly,and when refilled it leaks from somewhere in boiler,the worst thing is there is NO HOT WATER coming,even though heating is fine,when heating is on for like 2-3 hours then somethimes hot water starts coming,some times for 5-10 minutes sometime for more sometimes it wont comes atall,shown to someone he says first thing i should replace is Pressure release valve,and then have a look at heat exchanger,Any one having any idea?
