I live in the Southern US. Temps here have been around 100 degrees F
OR ABOVE for the last 2 weeks. It seems crazy to me that I have to
pay for Hot Water in this heat.
Surely there is some simple way to pipe water through some black pipes
on my roof and circulate it into a tank that feeds my water heater.
Is something like this feasible for around $500 or $1k?
I hooked the Polaris pump on my swimming pool up to several hundred
feet of heavy black hose pipe and put this on the roof of the pool
house, and coupled it with a thermal blanket. I was able to raise the
temp of the pool water significantly and extend the swimming season.
And help cool the pool house ( though this was a subjective
Sure. An electric water heater can be 30% of your electric bill!
So if you spend a couple of thousand dollars installing a solar water
heater, it will pay for itself quite soon.
Also there are tax credits and some electric companies or local
organizations may help to pay for the installation or provide low interest
And a solar water heater will work even in the winter. It does not need to
be hot outside.
But the thing with solar water heaters is that you are running all those
pipes outside. Don't want to run water through the pipes as this will freeze
in the winter! Instead they run a "solution" which will not freeze, then
circulate that to a heat exchanger with in turn heats the water in your
The best solar water heaters also have a solar electric panel and this runs
the circulation pump. Look in yellow pages for solar. Ask local solar
companies about tax credits, loans, etc. for your area.
Sorry Bill but I disagreed with you fining
According to Manufacture represenetive
it will take about 15 years to recover your investment
not counting if you have invested that money
and any repairs doing that period of time
in southern parts of country perhaps might be some what
beneficial but defiantly not in northern area
Professionally installed heaters can cost thousands, even after the
rebates and tax credits. My neighbor had one istalled - the heat
exchanger type. We don't have to worry about freezing pipes here, but
they tend to be cheaper cause you don't need high pressure pipes on
the roof. Anyway, with his savings, he figures it will take 8 years
to pay for itself. At which point I bet he will need a new pump or
A cheap system I've seen and thought about doing is the following:
Buy a scratch and dent hot water heater for cheap. Strip it down to
the tank. Paint it black. Put it in an insulated wood box with a
glass top angled at the sun. Pipe it in-line prior to your existing
hot water heater. Use most of your hot water in the evening or
night. You can find detailed directions on the internet for this type
of simple heater.
