Solar Hot Water

About Solar Hot Water

Heating water is the second largest energy load in homes today. In Western Washington, solar hot water can provide about 60-70% of your annual hot water needs. The solar hot water system acts as a pre heater for your traditional water heating system. It can be matched with electric, gas, and on demand water heating. So if there isn’t enough sun to heat the water, the traditional source can make up the difference. During the summer, the opposite can happen. The summer sun can heat the water so high that the traditional water heater has to actually mix in cold water before it can safely go to the tap. Solar hot water systems are low maintenance, they need to be cleaned off about once a year, and the fluid needs to be checked about every five years.


How it Works


Heat Activation

When there is heat from the collectors, a controller activates pumps.

Fluid Transfer

The heated solar fluid is then circulated from the collector down to the heat exchanger

Heat Exchange

The fluid then is passed through a heat exchanger where its heat is transferred to your water for use


The heated water is stored in a tank, ready for use.


The solar fluid is then pumped back to the collector to once again be reheated.

During times when there is little or no sun, a standard gas, electric, or on demand heater will heat water.


Evacuated Tubes vs Flat Panels

At South Sound Solar, we offer quality made in the U.S. systems that are proven to last 30 plus years. Evacuated tubes are usually made in China, and are not as high of quality as the flat plate collectors. Also, studies have shown that flat plate panels just work better in our climate.

It is for these reasons we only offer Made in the U.S. Flat Plate Solar Hot Water Panels.
