Other suggestions I have had:

* Heat a hot tub (don't have one. don't want one)
* Heat a swimming pool (great idea but somewhat over budget)
* Heat a greenhouse
* Lose the heat through some kind of buried pipe (Hassle and MDPE
certainly won't like the temperatures)


Would it be feasible to use some sort of reverse ground source device?
No heat-pump but just a long pipe running underground to dissipate the heat.

My green project for 2010 is to install a large thermal store in my home,
along with a solar array for hot water. This kind of panel:

One of the big issues with solar collectors (especially larger ones) is
the dumping of surplus energy once the store is "full". An issue for the
summer.

To manage the solar array I will be getting one of these:
http://www.resol.de/index/produktdet...d/3/sprache/en which
has a bunch of nifty features, amongst which is the ability to generate a
relay output on "over-temperature".

My thinking is that in an overtemperature situation a 3 port valve could
then divert the solar fluid (water/glycol) to some kind of heatsink. But
what kind of heatsink? (remember this will be running at 90-95C).

The obvious solution is to install some kind of radiator outdoors [caged

Any other suggestions?...bearing in mind this situation will likely only
occur on hot summer afternoons.

Go to the Navitron web site forum. They are into this. Lots of people who
have done it.
