In disputing the reading that our gas meter has in a usually empty property, British Gas are claiming that every boiler has a permanently lit pilot light. I'm pretty sure that isn't the case with some or even most modern combi's, and our C&M MX24 seems to be one that lights on demand as you can hear the spark generator. Am I correct that an MX24 should not be using gas when there is no heating demand?
There's no mention of a pilot light in the Installation, Operating and Servicing Instructions for Chaffoteaux and Maury's
Minima MX2 24 FF NG
In particular, there's no mention of one in the parts list or fault-finding sections.
The circuit diagram shows a spark generator.
As you say, most modern boilers don't have a permanently-lit pilot-light.
