Hi
I seek some advice on replacing an existing regular boiler.
I currently have an old Potterton 10-16 Netaheat electronic, which is around 35 years old and still working OK. It is fitted to a std 'Y' plan system with boiler in utility room and separate hot water tank, pump, valve etc in upstairs airing cupboard.
I would just like to do a direct replacement with another regular boiler such as a Worcester Bosch Greenstar 15Ri.
However, I find that any new boiler requires the pump to be directly connected to the boiler to allow for the pump overrun ability.
Consequently, as I have been advised, this will require getting wire(s) form the boiler to the pump in the airing cupboard. Unfortunately there does not appear to be any spare wires available and whilst not impossible getting wires form the utility room to the airing cupboard would be extremely difficult, unless some of the existing wiring can be re-configured, which I doubt.
So what is/are the solutions?
I understand that there are Mainslink pro's or similar, that can allow one to remotely connect the boiler and pump together, are they any good and a possible solution, or can I use a system boiler such as the Worcester Bosch 4000 15Kw with a vented hot water tank and if so what would this entail?
The pump would then be integrated with the boiler, but can I retain the existing expansion tank in the loft or do you have to use the one in the boiler?
Does it also require that you have the boiler supplied with a separate mains fed water supply or can it be fed from the cold water tank in the loft?
Would appreciate some advise/suggestions.
Thanks
