Me again - back on the subject of a thermal store/heat bank for export to
None of the companies that I have contacted seem interested; Albion, Range
and DPS. I've emailed and faxed them a comprehensive spec. of what I want.
Albion and DPS have not responded at all.
Range came back and suggested that I wouldn't get enough flow rate through a
thermal store and as I was heating it from one source there was no advantage
going down that route, and suggest an unvented cylinder. To me that is a non
starter as I will have to mess about with shower pumps etc.. to get decent
As a final option one of the local dealers imports Telford products. I see
that they do a thermal store, not exactly what I wanted because it uses a
coil and not a heat exchanger, but it's an option. Does anybody have any
experience with Telford thermal stores, what is the quality like etc.?
Another thing that attracts me to the thermal store and heat bank concept is
that I would like to add some solar heating in the future. So provided I put
the right connections in place I should be able to quite simply add the
That's pretty much what I am thinking of doing. I went to see the guy who
imports the Telford http://www.telford-group.com/contents.htm stuff this
morning, and he is getting me some prices for the Tristar and Tristor
products, which don't seem to appear on their website.
One of them is almost what I want without the external heat exchanger. So I
would only have to add the heat exchanger, a pump, blender valve and some
I was thinking that it is simpler to have the cylinder water heated by the
boiler, or rather the cylinder water and the radiators. That is if the heat
source is only a boiler.
On some diagrams I have seen a two pump primary system, where there is a
pump circulating water from the cylinder to the boiler and another
circulating water from the cylinder to the rads. However I don't see why I
can't do that with one pump and two zone valves, as in a normal S (I think
it is) plan.
That way there would only be two pumps in total. One for the cylinder and
Rads and another to pump the water from the coil through the heat exchanger.
I was planning on putting a small header in the loft above the highest rad
and therefore keeping the whole system vented.
Anyone see any problems with that arrangement?
I've just sent them a mail. Hopefully they will be quicker than the others.
I guess it might just be that it is holiday season over there!
I need to at least make contact early next week, as I'm traveling to the UK
myself on Thursday. Visit my sister in London and do some shopping for
kitchens and bathrooms - I was hoping to get in some holiday too, but as
SHMBO is coming I guess I'll be looking in shoe shops most of the time!!!
If I can make contact with a good firm, I could visit them with plans under
arm to discuss the options.. That's what I'm hoping anyway.
I'm using Wilson Logistics to consolidate and forward my stuff. I've used
them before and they are used to dealing with the Falklands, but thanks
