Rated 5 out of 5 by Honeywell L641A Cylinder Stat Used to replace older Honeywell Stat, Easy to replace just fit ex cables to new stat, fit the new strap in place and switch on. Works well. 3 Sep 2015
Rated 3 out of 5 by Good but not perfect This is the 3rd one of these I have had to buy in 8 years. It is used on a hot water tank to control the Worcester boiler. I have tried others but they are not ratted to 16A like this one, but every few years the micro switch packs up and we get no hot water. Plus side is they are very easy to fit and come with a new strap each time, although I re-use the old strap. 4 Jul 2015
