Hi,

My heating system is a myson apollo 30b with a 3 way valve etc.

The other day wife said was a popping noise coming from kitchen where the programmer and boiler is , on investigation i have found when you turn down the tank stat which is a drayton hts 3 it when it gets below the temp and you can here the click in stat it causes the fault, Sometimes tripping the main rcd in the house,

I changed the 3 way valve,programmer and tank stat about 18 months ago and have had no problems up to now

I also looked at the fuse in the spur for the heating which is a 13amp should this not be a 5amp?
 
fuse should be a 5 or even a 3a
check the 3way diverting valve for water inside it sometimes the valve shafts leak
