thank you for pointing this out. I'm not at my static van at the moment, but will check when I next go for a holiday. :)
I have a central heating boiler, which does both the hot water, shower and taps, and also the central heating. I will ask the site manager about this recall.
Based on the fact that your boiler does the hot water and the central heating, it sounds like you have a combi boiler. Combi boilers are not affected by this upgrade so no need to worry!
If you have any further concerns, please do not hesitate to contact us.
