All was pretty much working fine yesteray. Today, the central heating keeps locking out. Hot water seems fine.
However, I've noticed recently (last couple of weeks) that the water pressure seems to keep being low (as displayed by the pressure gauge). I obviously fill this up. The pressure needle rises much faster than usual (as if it's filling a much smaller area)
There are no apparent leaks and all the rads are full.
So, when the Central heating is turned on, it runs for around 1min, then the pressure gauge shoots right round to max, lots of banging, boiling and noise, the lock out light comes on and the pressure drops back down.
It's also venting small amounts of hot water over my garage floor everytime it does this.
Any ideas? Any help gratefully received.
ps. To top things off, the light in my garage (so i can see what I'm doing) has just blown too!! Brilliant, eh
