Hi, I am in the middle of planning a new boiler stove system for my house. As a back story I've no idea when it comes to plumbing, I've done some research and I am trying to get an idea of what is achievable and efficient. I will of course be using a plumber to do all the work, I just want as much info as possible.
At the moment all dhw comes from economy 7 immersion. I have bought a boiler stove with an output of 6kw for water heating. The economy 7 tank is around about 100 litres direct copper cylinder. It used to be fed by an open fire back boiler, the pipes have been cut and blocked off. Heating is night storage.
From days of looking over some systems, I can't see one in particular similar to my idea. I would like to move the direct cylinder to the loft space and connect this into the central heating circuit. I would also install an F+E for this circuit. On ground floor I would install an indirect vented copper cylinder, the heating coil would be fed from the very top of the direct cylinder in the loft. The cylinder would have twin immersion, top immersion for mains electricity "boost" and lower connected directly to solar panels for summertime water heating. I would have a circulating pump, but I'm not sure where this would be best placed. Either on the return from the radiators, the return from the indirect cylinder or the common return to the stove.
As I have said, I'm not a plumber, I'm a truck driver, so I'm not going to get offended if you say I'm wrong about anything. I have drawn some sort of schematic, and I will allow you to laugh a little at that. I'm also on a very tight budget, so suggestions of fitting a combi boiler won't be necessary.
Does this system look plausible/efficient?
Would the heat stored in the direct tank in the loft be enough to heat the indirect dhw tank if the fire wasnt lit?
Would it take too long to heat 100+ litres of the central heating system?
Cheers for reading.
