How Solar Water Heaters WorkThe above diagram gives a graphic representation of how solar water heaters work:
- Solar collectors, or panels, harness the sun’s energy and use it to heat up air or water.
- There is always some kind of storage. For pool heating systems, the pool itself is “storage.”
- Cold water passes through the solar collector first, which preheats the water.
- It then passes through the conventional back-up water heater (these are simple systems that do the job).
- Sometimes the back-up water heater is connected with the storage tank, bypassing the separate heating unit in a two-tank system. Here is an example of an Active Indirect One-Tank System:
- To provide hot water, pumps are used to circulate water through your system and into your home.
Is a Solar Water Heater Right for Me?The first thing most people want to know is “How much?”. For a quick answer, expect to pay between $2,000 and $4,000 for a solar water The answer, however, is more complicated than how much the upfront costs are. Don’t be surprised when you see your water heating bill drop 50%-80%. You also won’t be subject to the rise and fall of fuel prices. Besides having more predictable gas or electricity bills, you will also be helping to promote technologies that are good for the environment. Replacing your standard water heater (useful life of 10-15 years) with a solar water heater (lifespan of about 20 years) will “offset the equivalent of 40% to 100% of the carbon dioxide emissions of a modern passenger car” (U.S. DOE). One thing to consider when shopping around for a solar water heater is if you have an unshaded area on your site that faces in the southern direction.

Types of Solar Water HeatersOnce you have decided that a solar water heater is right for you, you will want to decide which solar water heater system is right for you:
- Direct Solar Water Heater – uses a pump to cycle water through the solar panels/collectors to preheat the water; this can become a problem if the temperatures outside are frequently below freezing.
- Passive Direct Solar Water Heaters – circulates water or heat-transfer fluid through the system without using pumps or electricity. These systems are great during power outages but suffer in freezing climates.
- Thermosyphon System – warm water rises and colder water sinks in this system, creating the need to place the solar collectors below the storage tank so that
- Indirect Solar Water Heater – uses a pump to circulate friendly antifreeze through the solar collectors and heat exchanger. These systems are popular in areas that are prone to freezing temperatures.
Solar Water Heater Sizing:Another factor you will want to consider is how large your solar water heater needs to be to accommodate your home. You will need a tank large enough to provide as much hot water as you’re likely to use in an hour on any given day, and it also needs to keep that volume of water at the appropriate temperature until you need it. Although it may be tempting to install a solar water heater on your own because it doesn’t have many moving parts, this would be a bad idea.
