Well -

a: it's a Potterton

b: Its a Lynx (or Jynx as I was always taught)

c: it's a Potterton


d: could be worn burners/badly adjusted gas valve.

Either way, get a good engineer ro9und with a few to patch and replace.


When was the last time it was serviced? Was it done properly (i.e., with a gas rating).

Can you gas rate the thing? Run it at full tilt and tell us how long it takes the gas meter's red needle to go round once.

£65 in 21 days! Its not like its been snowing outside
I put 20 notes on a gas meter card thursday and it ran out sunday, thats on a brand new combi on low fire.

i have just been out and taken the front cover off and tried turn the temp controls and watching through the little view window on boiler when turn to min no change in flame size colour on both boiler dial and ch.

you mean turn it on

turn on and watch gas meter i have 5 black dials and 3 red dials (1 large 2 small) what am i watching

thank you for helping me

Bugger - you have a metric one. These were a reason to stay out of Europe - takes twice as long to do a boiler service now - just kidding.

Take a reading. Run the bath for two minutes

Take another reading

Subtract the two and post back.

no snow in cornwall so cant blame it on that, used to be on pay as you go gas but was costing me £5 to have a bath (not very deep)

 

[salts100]

ok ran hot tap in bath (not hot shell i add only ever runs warm)
reading before starting
00140 228
after
00140 310
ran for two mins at max on hot water only no CH
so used 82 in the red things
is this any good

 

[Dan Robinson]

Maybe even a little under gassed...

 

[salts100]

so what does this mean for bigger gas bills

 

[Dan Robinson]

As was mentioned on a similar thread - gas is damn expensive now.

If you are worried get your supplier to double check the meter is accurate and don't take their first answer.

Make sure you have a programmable room thermostat - or at least an accurate room stat and clock.

And insulate the nuts off your house.

thank you for the help.

what is with the pressure dropping off to 1.5-2 bar to 0 overnight

 

[salts100]

guess potterton dont have a good name than
what would you recommend for most gas friendly but very good with heat

You have a leak somewhere.
