Rated 2 out of 5 by from Worked well for 3 months Brought this in June and fitted it mid July due to a 13 year old one giving in, easy to change and fit if you know the basics (I'm a qualified water plumber, not gas). this new one kept the water on standby hot throughout the day set at 55 degrees, not at the full 70 degrees it can go up to. On October 13th however, it no longer works, water does not heat up, ran a tester on it and there was power coming in to the thermostat but no power passing through it, I have an emersion heater so that required 2 of these, the other one packed in 4 days after the first one. Just over 3 Months after fitting. Due to not being able find the receipt and not having a screwfix account at the time, I couldn't return these, a mistake I won't make again as I now have an account to keep a record of the items I have brought. I don't recommend these at all.
