Hi Robert, I was wondering how you got on with the modifications to fit the zone valve and stat. How did it work out for you.? I am looking to do something similar. Regards, Tony

Hi Andy, Have been in the loft. Was not easy to get to the tank as lots of rafters and low head room. Yes, I have a small tank and large tank and the cylinder is an indirect one. I have mapped all the pipes and stop cocks etc and feel more confident now having been up there. Plan on...

A5 would be better, but not essential. £16 is a good price point. The odd bit of advertising would go down fine, signposting where to get stuff done, what is recommended brands and further reading etc. Packed with pictures, charts, facts and figures and simple tips to get stuff done.
