Denver, CO Water Heaters: How Do Solar Water Heaters Work?

Solar water heaters are a great way to conserve energy and reduce utility costs. Because Colorado is also one of the sunniest states in America, harnessing solar power makes a lot of sense in Denver. While electric and gas-powered systems are common throughout the country, there is really no substitute for the efficiency of a solar water heater. They are affordable, with no major investment upfront such as photovoltaic panels. In this post, we’d like to explain the basics of how a solar water heater works. The more you know the more control you can take over ever-rising energy costs. For solar water heater installation in Denver, call Bell Plumbing and Heating today!

There are two basic components of the solar water heating system.

1. Collecting solar energy. Instead of using photovoltaic panels, solar water heaters use a solar collector, which is typically an insulated box coated in glazing, to maximize heat retention. Inside the dark interior are tubes arranged for maximum heat absorption. Anti-freeze coolant circulates through these tubes, which essentially convert the radiant energy of the sun into usable heat.
2. Storing solar energy. Just like a conventional water heater, your hot water is stored in a large insulated tank for when you need it. Your tank will use either a heat exchanger or direct heating to heat water. It’s designed to provide up to 1 hour of continuous hot water, and the temperature remains steady so long as the solar collector continues to convert the energy of the sun.

The solar water heater can be supported with a backup electrical or gas water heater, so that you never have to worry about whether there’s enough sunlight to take a shower. This will turn on when it senses that your solar collector needs a boost, or when the temperature in the tank falls below a certain operating level. For days when sunlight is not in great supply or in winter, you will probably need this optional backup.
