[Greenbuilding] hotter water

[Nick Pyner]

OK. I wish I could find the article. The big tank really was seriously big.
I suppose there are situations where climatic conditions are such that
trying to get all-solar is really a hopeless cause and a large tepid supply
for pre-heating makes more sense.

This is a bit like some work I am on at the moment with ski lodges. I
assumed that there were no gas heaters around because there is no
reticulated gas. It turns out that there is gas, so I suspect the dearth of
heaters is because they aren't up to the job. If an instant gas heater was
installed, it would need to be in tandem with something else.

More to the point, I imagine a really large solar storage tank would make
stratification worth pursuing.

Hi Nick;

 The large tank may be a Solar preheat tank, and the
smaller one a conventional gas or electric backup tank
heater, to bring the water temperature up to 120-140F.
That is an arrangement that has been used a lot.
