OT : Boilers

Oh, arrr.

 

Sounds like they begrudging did what they were contracturally obliged to
do ... but only after you started creating waves

Now, if you were a little old woman who didn't want to make a fuss ...

 

I don't hear it any more.
Gawd bless tinnitus, I say.

 

There's another *slight* possibility (though the symptoms aren't quite
the same): do you have mixer taps? My old house had a problem where
the cold mains pressure was so much higher than the hot pressure
(actually in the tap mixer) that if the cold tap was turned on too
high, cold water would get pushed back up the hot pipe into the hot
water tank.

 

That happens when all the imported made-in-France /Italy mixers get
fitted to UK homes with tank systems. Those mixers are designed for
equal pressure feeds, usually mains pressure.
The traditional British mixer didn't mix at all until the water was
actually exiting the spout, so could cope with widely differing
pressures.

 

I've had them (BG) here for some years. They upgraded the system here
with a condensing boiler. They've maintained it without complaint for
5+ years now despite having to replace the main hot water tank with a
leak and it taking them a day to replace.

They come when I ask and do the work they agree to.

I can't fault them... yet!
