    Hi Winty, Just returned from a week away, so slow in responding. Coldstream 450 accumulator has been supplying our combi plus cold water to showers since it arrived - how long ago is it now - ten months? Did you ever get one? I could send some photos of the connections etc because there is...

    Cold water accumulator/potable water expansion vessel

    Hi Tony, Yes, I will now replace an accumulator that is only three years old. However, it would be unfair to use this as an indication for the high cost of an accumulator, for two reasons. 1. My current accumulator still works just fine. The black residue lasted for about three days and...

    Cold water accumulator/potable water expansion vessel

    Hi Steve, This is very interesting info. What we can perhaps establish, then, given it has worked fine over a three year period at ours, is that an Altecnic (its an Ultra Pro 300) will dispense the water out of the top end - even when it is not intended to be done that way :) Here's a...

    Cold water accumulator/potable water expansion vessel

    Thanks Simond for the added (and otherwise hard to come by) detail. Perhaps the most interesting part of my story (left out earlier) was the time I spent 3 years back trying to convince my cautious plumber that the accumulator principle would work for us. He had never done one before. He is...

    Cold water accumulator/potable water expansion vessel

    Yes, seems a reasonably assumption... they should be able to advise on this. Good luck taking this forward. I just this afternoon ordered a Coldstream 500 from here: http://www.plumbclick.co.uk/gb/home The path to find the vessels is: Home > Heating > Hot Water Cylinders &...

    Cold water accumulator/potable water expansion vessel

    Hi Winty, Putting it outside sounds interesting. Note, though, that you will have to prevent it from freezing. Last winter was awfully cold!! If there is a longer cold spell you're in trouble, no? A wooden lean-to might not be sufficient... maybe if it is well insulated and some kind of...

    Cold water accumulator/potable water expansion vessel

    NOTE: See comment by Steve32 later in this thread about the correct way to connect an Altecnic accumulator. Hi Winty, I’m not a plumber. However, we have an Altecnic 300 liter expansion vessel installed in our house, which, yes, serves us as an an accumulator. When I first considered...
