solar pool heater

Here is the problem - we have a solar pool heater. Whilst the 'heat' is solar and thus free, the pump uses electricity and thus isn't. We also don't have a pool cover. So over the last couple of weeks the pool has been slowly heating up during the day, but cooling over night. Most nights are about 15 degrees. Thus the pool hasn't actually got warm enough to make it worth while getting in.

So here is the question - when does it become viable to run the heater?

Finally got my Aussie passport

No more (or at least less) queuing to get back into the country! And - oo - it an 'ePassport' - with a RFID chip that can probably be cloned in about 15 seconds... but will get me though the SmartGate at the aussie side.

It's labour day long weeekend - and it is raining - heavily. How very British.

I mean - two days ago it was 33 degrees - now it is only 17 degrees!

And did I mention the rain???
