Anyone who has ever shared a house with family, friends, or roommates understands how expensive hot water can be. Rather than struggle to minimize the number of showers you take, why not get a solar-powered water heater? But what is a solar water heater? We’ll take a moment to elaborate on this innovation in solar technology.
What is a Solar Water Heater?
As the name implies, a solar water heater is one that is powered by solar energy. Like traditional water heaters, this system comes with a storage tank and solar panels. Thus, you can enjoy hot showers every day without stressing about your water bill.
Passive vs Active Systems
According to energy.gov, there are two main types of solar water heaters, active and passive. The main difference is that active systems feature circulating pumps and controls while passive systems do not. Passive systems are cheaper and longer-lasting than their active counterparts, however, they may not be as efficient or practical depending on your needs.
Active Water Heating Systems
There are two types of active systems: direct circulation and indirect circulation. Direct circulation systems are preferred in climates that rarely freeze. Indirect circulations feature heat-transfer fluid to heat your water before pumping it into your home. This is ideal for colder climates.
Passive Water Heating Systems
There are two main styles of passive systems: the integral collector-storage system and the thermosyphon system. Both of these system types are designed for warmer climates that rarely freeze. Integral collector-storage systems are the most cost-effective option of all solar water heaters. This affordable pricing makes them a great choice for home-owners on a budget. Thermosyphon water heating systems have a heavy storage tank that requires special attention and are more expensive than integral collector-storage systems.
