Solar water heater question?

Question

we have a solar panel for hot water. Is it worth changing to a washing machine which will accept hot water? Our current one is cold-fill so uses electricity to heat the water itself.

also dishwasher

Answer 1

The normal solar water heater tank size is dependent on the number of people using it.  I have 10 people using my system, so it's 20 gallons per person per day or 200 gallons.  It was built in the late seventies and still working.

Tank size = 10 people X 20 gallons

Answer 2

Yes sir, it is..

but be carefull, that all depends on the size of the hot water storage.

a washing machine consumes a lot of hot water, and you dont want to run out of hot water.

for this purpose, and if the storage volume is not enough, i suggest you either increase the volume, or try install a simple integral storage solar system (Batch).
