Gas cookers in flats

[tryitandsee]

expertgasman from another earlier/other thread,

You said ....With regard to the FFD, that is always on an oven, and has been for decades. In a flat you now have to have a flame supervision device on ALL burners.

Interesting point. I assume this does not apply to existing cookers installed in flats already.

How do they operate - does spark generator keep on sparking if flame goes out or does that stop. I bet this will add a fair bit of money to production of a gas cooker

Having just googled some sample cookers, gas ones are one and a half times more expensive. Time to go electric me thinks.[/quote]

Firstly, it does not apply to cookers fitted before a certain date.
Secondly, they generally work in the same way a thermocouple lead works on a boiler.

Fair old bit of work changing them aswell - especially if the burner uses a t/lead and not a mercury type valve.

they are thermocouples,two metals which when heated produce a small electrical charge so keeping the valve open

And flame supervision through the electrodes, not new either been on some cookers over 30 years

if your in a house its fine to buy a hob without FSD protection.
The reg came in a couple of years ago and only applies in flats.
If you buy a hob without FSD now it cant be fitted in a flat.
If you already own one,move into a flat with one or take your old 1 from your last property to a new flat its also ok not to have an FSD device fitted.
Electric is more expensive to use than gas and i dont think it makes hobs much more expensive either as they pretty much all have them now due to the new regs and would miss a gap in the market by not having an FSD to protect the burners.
