Solar domestic hot water (SDHW) is a safe, reliable, efficient, and proven technology. It also has one of the fastest payback times in the renewable energy industry. The prices for SDHW systems range from $5500 to $7500 for most residential applications, which makes them one of the most affordable technologies as well.
Solardelphia installs closed-loop SDHW systems. These systems use a food grade glycol solution in the loop to extract the heat from the collector and bring it into your home. The glycol acts as an antifreeze so your system can work all winter long. The heat from the collector is brought down to a heat exchange unit where it is extracted from the glycol solution, transferred into your potable water, and stored in a pre-heat tank.
When there is a demand for hot water in the home, the pre-heat tank feeds your existing hot water system (now a backup system) with solar heated water. Most of the year your backup system will not even come on, but during periods of high demand and low solar exposure (i.e. an extended period of dreary winter days) your backup system will pick up the slack and you’ll never go without steamy hot water.
At Solardelphia we install both flat plate collectors and evacuated tube collectors. We feel that each technology has an appropriate time and place for use and we will help you decide which is right for your site specific application. Call today to find out which is right for you. |
