    What's this, and where can I get one (immersion heater nut/machine screw thing)

    Off a Backer immersion heater element. Unlike others I've seen, rather than having a long threaded rod with a nut on the end to hold the cover in place, the threaded rod does not extend beyond the cover, and relies on this sort of female machine screw thing to hold it in place.

    My boiler isn't heating up water overnight like it should. I have horstmann economy 7 quartz. The timer light doesn't turn on. Boost is working but it takes a long time to heat up the water. Is it my thermostat that needs replacing?

    Understanding economy 7

    Economy 7 horstmann quartz timeclocks for water heaters with dual elements, from my understanding they would require two separate supplies to work on a off peak supply and regular supply, although after looking inside one today and looking at diagrams only 1 supply is used. How is this possible?
