To a certain extent that's my feeling but I just couldn't resist thinking
about how the pool could be used to make the whole thing work
better and perhaps get to the 20% extra promised by the boiler.
I still sort of think that there should be some way of making use of
a low temperature sink but I'm beginning to see that its
more difficult than I first thought.
