Over the past few years, solar power has gained immense popularity amongst homeowners. Everyone is looking to utilize the power of the sun and enjoy increased savings and efficiency each month. Now, you’re considering a solar water heater in Oahu, HI, right? You’re certainly not alone. Countless homeowners and local businesses have found themselves thinking the very same. Is it a smart investment, though? Let’s break down solar water heaters and how they can help the island.

How Solar Water HeatersWork

A solar water heater includes two primary components: storage tanks and solar collectors. Now, there are two primary types of solar water heaters including an active system, which uses a circulating pump and controls, and a passive system, which does not.

To break things two down further, an active solar water heating system includes these options:

  • Direct Circulation Systems – These units pump household water through the collector and directly into the home. These systems are optimal in warm climates.
  • Indirect Circulation Systems – Such units are utilize a non-freezing, heat-transfer liquid through a collector and heat exchanger. The heated water then flows through the home’s pipes. This system is ideal for cold climates.

Then, we have the passive solar water heating systems:

  • Integral Collector-Storage System – This type of passive system works best in regions where the temperature rarely, if ever, falls below freezing. They also work best for households with daytime or evening hot water needs.
  • Thermosyphon Systems – Water will flow directly through the system, as warm water rises to the surface and cool water sinks. The collector should be installed directly below the storage tank, so the warm water rises properly. Such a system is reliable, provided the unit is professionally designed and installed for optimal performance.

Advantages of Solar Water Heaters

Let’s now discuss the advantages of a solar water heater in Oahu, HI. You’ve likely been waiting for this portion. The benefits of such a system are usually the deciding factor for most homeowners.
