The pump is really the main usage. I have solar heat and a gas heater
but we never use the gas. Most people in the world would say our pool
was always warm enough. It is about 20 now, I will get in it when it
is 23 and my wife likes 29 or more. That is most of the summer tho.
The solars will extend the season for me to about 9 months and in the
3 when it is too cold to get in the pool I switch the solars over to
the spa. I can usually get 38 or more for free in the solars.
Isn't it the case that if either of them goes through your heart it can kill you? Anything over 80 volts or something like that is all the same.
The only difference is that much higher voltages can burn your skin, or jump across gaps where you least expect it. But that's kV.
Take notice: when this sign is under water, this road is impassable.

It's the current that kills. Not sure on the numbers, but maybe on
the order of 30ma and above can effect the heart rhythm. The human
body has some resistance, X. If you put 240V across that, you're going
to get 2x the current as you do with 120V. But.... That's really a
red herring the way the system works here. To get 240V you'd have to
be across both hot wires, which is extremely unlikely. Most common
is for you to connect between one hot wire and ground, like standing
in water, touching an appliance case, faucet, etc. In that case
you'd still only get 120V. Between each hot and ground you have 120V.
Not sure how it works over there.
You're thinking about the USA.
Mr. Macaw just posted that the two wires coming into his home in the
UK were 240 and 0.
The comparison I had made was between the UK and the USA, and I said I
thought more people died of shocks, per capita, in the UK than the
That would definitely be true if all Britts had as little regard for
code, the rule of law and safe electrical practices as Macaw does.
There are a lot of "bodgers" in the UK - and the competency of many of
them leaves a whole lot to be desired. In the UK, Mc Guyver would be
an absolute genius.

30ma can't be achieved just as easily with 120V as with 240V. The
human body has resistance, tap water has resistance, etc. Under the
same conditions where 30ma is going through you at 240V, you'd only
have about half that at 120V.
