My old Economy7 water cylinder started leaking so I had a new one installed. Both the old and new cylinders have an indirect coil from our multifuel stove as an auxilliary top-up. The water temperature from my new cylinder, in a morning is just lukewarm. Sadly the old tank started leaking but it did deliver a tank full of lovely hot water each day. I have checked the obvious things like the electrical switch for the supply to the immersion is in the on position, the thermostat is set to a hot setting (70°C) and whether the RCD had been tripped. What else could have failed in my system? Any advice or suggestions would be great. -
Just wondered if anyone has experience of running an ASHP using the cheaper rate economy 7 tariff and whether it makes any real difference in running costs. I seem to remember that you have to pay a slightly higher day rate if you have E7, and that, coupled with the fact that the ASHP would be running at night when it might be cheaper but also colder would seem to maybe cancel any financial benefit. Also, it seems that running an ASHP 24/7 makes better sense and it's unlikely to be able to run an ASHP on normal rate during the day and E7 at night. Thanks in advance to anyone who can shed some light on my ignorance!

Having eventually got around to organising myself to change the bottom element on my E7 water heater, I have found it is leaking. So that takes one unknown away. So are all Vented, E7, DHW cylinders basically the same. To the best of my measuring, mine is 1.5m high, 0.5m wide and with about 40mm of insulation. The elements are both on the same side with the feed pipe going in at the bottom and a few degrees anticlockwise, the drain is opposite. There are some pictures below. I have been to a couple of websites and they seem to be around the £300 mark. Is that about right? I am hoping to just get a direct swap as that will save any mucking about with pipes, but I could, fairly easily, extend the top pipe downwards and re-jig the feed pipe. would rather not though. It would give me less heat losses, a slightly cheaper cylinder (though not much) and a larger airing cupboard (which might be useful). (edit, seems the website does not like .png files)
