Solar Power Water Heating

I was wondering is solar water heating a more cost efficient use of solar power over using large arrays to power your house or large solar thermal plants that are being contemplated all over the world.

It depends on how you do it. Passive solar is the most efficient and reliable. The more pumps, storage tanks and controllers you use the less efficient and reliable the system will be. The egyptians were successfully using passive solar 3,000...

evacuated tube heat pipes

I need to know all the details to understand how to do this, complete. Hypothetical Situation. People want their water heater to tie into solar power heating (heat exchanger). I don't know the process, the materials, and cost for everything. I was...

The panels look similar to solar electric panels, but actually have water or glycol (anitfreeze) in the them. The water is circulated through the pipes, heated by the sun, then returned to the tank. Its pretty expesnive and only really effective in

I am considering solar power to heat water in the house how effective is it and can you receive a government gant with the costs?

To my knowledge, there are no "grants", but there are some new tax incentives. You'll have to come up with the cash up front or finance the job, then get the incentives next April. Check to be sure what you do and your tax status...

This is for a science project, so make sure it is not too big or expensive.

Fundamentally, a solar water heater consists of the following parts: a solar collector - converts solar radiation into useable heat
a heat exchanger or pump module - transfers the heat from the solar collector into the water
storage...

I want to install a solar powered heating element in my hot water tank. I want a very simple system with out batteries or thermostat control. Basically convert solar power to electricity & send directly to the heating element which is fitted...

The technology to convert solar power to electricity to heat water is very inefficient. Solar photovoltaic panels are expensive. You should think about using solar panels to heat water then circulate that through your hot water heater. There...

for the same tasks in new or used homes no matter if there going to be or are powered by coal and oil or coal and natural gas etc...? Even if it used fossil fuels aslong as it was in only a night time and auxiliery role? Could this be done in a way

Unfortunately solar photovoltaic systems are very expensive ways to generate electricity. The cost is generally 5 to 10 times the cost of purchasing electricity from your local uitlity.

Solar hot water is a little less expensive. In...
