it’s for a science fair .
our company is GO ECO .
we need a name for our product. a solar water heater

I have some 6′ X 4′ double pained, tempered glass windows, and I intend to mount them together over a plywood, and 2×4 box, with the inside painted flat black.

I envision using CPVC Pipe, plumed from the cold supply line of my water heater, diverted to the solar water heater, and returned into the water tank into the intake. I’m doing tests to see how quickly each size of CPVC Pipe heats to 120′ (F).

My question is… is there a problem with diverting the water to the Solar Pre-heater that I should know…? Anyone with experience doing this sort of thing who might have some advice or information?

I know 3/4 inch pipe heats to 120′ (F) in 30 minutes, but it doesn’t give enough volume for a shower or a load of laundry… still testing the 2" line.

A new homeowner is debating between installing a solar or a gas water heater. The gas water heater should last 20 years and will cost 5 to purchase. The estimated fuel use, based on a family of four is 0 per year. The solar water heater is more expensive: the equipment costs 00 to purchase and install. Additionally, the homeowner estimates that the annual fuel cost will be in electricity to run the pump and to heat the water on cloudy days. He also estimates for annual maintenance. He does not know how many years the solar water heater will last, but he estimates that the equipment should last at least 10 years.

a.How many years would the solar water heater have to last to break even with the costs of the gas water heater?
there is no rate at which money is discounted given

b.What is the cost of both systems at the break-even point?
c.If the solar water heater lasts for 20 years, how much will the homeowner have saved?

I’ve been searching online all day for solar water heater MANUFACTURERS and am only finding installers, retailers, or wholesalers. Does anyone know of any manufacturers? I’m In Phoenix, but the manufacturer does not need to be local. I need contact info so I may become a distributor. thanks.

i need answers to question b and c please and thank you

The answer for part A. is shown below=
gas water heater:
345 + 450x

solar water heater:
1900 + 135x

set them equal to find the breakeven point:
345 + 450x = 1900 + 135x
315x = 1555

x = 4.9365 years

I have a garden shed and I was wondering if I could lay a garden hose on the roof the make a cheap solar water heater? I’ve heard garden hoses are quite effecient in warm weather but I want a few opinions. Before you say "Why not buy a proper heater" I’m 15.
@ Iffy: Yes of course it would freeze in this type of Winter weather but I’m chatting about using it in the Summer.
