Hi There
This is my second post - I wonder if / hope that anyone can/might help. We have a Glowworm Boiler or Megaflo making whining sound at home...pulsing in waves (see YouTube video here:
Is an unvented cylinder megaflo - maybe I should replenish the air gap and see if that helps?
Thanks...
They measured it with a micrometer screw gauge - 31mm apparently...
Yes it was a GT1 survey. The commercial upgrade dude I spoke to said they would another GT1 (and that they are allowed to do them and submit them to cadent...)
Hi There,
We need some help..please. We have been told SO many different things about this - its impossible to know who to believe. For the record - I'm a chef - not a gas engineer.
We have been happily working from 2 commercial kitchens on the ground floor in our commercial catering premises...
