Although we have access to an enormous amount of natural energy from the sunlight, few people seem to take advantage of the benefits of solar energy. And while choosing to switch your entire home to solar energy may be a big step, you can make some minor changes toward a more efficient home right now. Consider switching to a solar water heater for your new water heater installation. These units are extremely efficient and can be just as effective as your current heater. The two major types of solar water heaters, active and passive, are described below.
Active
The main difference between an active and passive solar water heater is that an active system has controls and pumps while a passive system does not. An active solar water heater may rely on two different types of circulation, direct or indirect. Direct circulation systems pump water through the solar collector, and solar radiation heats the water. Water flows back into the storage tank with a backup heater attached and into a pipe to reach your home. Indirect circulation systems pump refrigerant into the solar collector, which absorbs heat. As the refrigerant flows through a heat exchanger in the tank, the water is heated.
Passive
A passive circulation system does not rely on any pumps. Instead, water flows into the solar collector where it gets preheated. The water then moves into the storage tank, where an additional gas or electric heating element helps it reach the proper temperature. While this type of system may still need to use some energy, it will use significantly less as water is already hot before reaching the tank.
What Are The Benefits Of Going Solar?
Choosing a solar water heater is one of the most efficient ways to heat water in your home, and it may reduce your hot water bills by up to one half. Solar water heaters are also very effective and may have long lifespans with proper maintenance.
