I have a complex heating system (At least it seems like it to me) It consists of
Heating Zones:
Zone 1 - Radiators
Zone 2 - Hot Water Tank 1
Zone 3 - Underfloor heating
Zone 4 - Hot Water tank 2
Zone 5 - Air Heating in swimming pool
Zone 6 - Water heating in Swimming Pool
Each zone has its own pump (6 pumps in total) and each has its own electric gate valve (6 in total)
Zone 1&2 are controlled from a standard central heating timer with tank and wall thermostat
Zone 3&4 are controlled from a standard central heating timer with tank and wall thermostat
Zone 5 has no timer because it is constantly on but does have a wall thermostat
Zone 6 has a timer and thermostat in the pool water heat exchanger
All of the zones are fed from a manifold type arrangement near the boiler and are either 28mm loop or 22mm loop. The pumps and the electric valves are located all over the place.
The Boiler:
There are 2 heat sources-
2 x electric boilers connected in parallel
1 x oil boiler connected in series to the electric boilers, but after the electric boilers in the flow.
The Problem:
The boilers are not connected in any way to the heat demand side of the system. they are powered constantly and use their own internal temperature to turn off. There is no overrun from a pump in order to empty the hot water from the boilers. The electric boilers are overheating and burning out the heating elements. I have just replaced them a couple of times, but they are getting a bit expensive to just keep doing that. I am also about to extend the property which will result in a further hot tank and some additional radiators.
What I Would like to achieve:
I would like to be able to link the whole system up in a more simple arrangement. Would like to have a single pump if possible, would like to have a single controller to time manage the hot water, radiators and under floor. I am not so worried about the pool heating being in a different place because it is not changed in the same way as the house is.
I could really do with some help on:
How can I get the system working in a more integrated way regarding boilers and heat demand. There will potentially be 7 zones once the extension is complete.
Can I get this all running from a single pump that can be integrated in a way that will remove excess heat from the electric boilers specifically, but I guess also the oil boiler.
What is available that can control the on/off heating of 3 water tanks, 1 radiator loop and 1 underfloor loop.
