Did you know that there are three different types of solar water heaters available from The LeverEdge?

We offer multiple styles of water heaters because no two customers have the exact same needs for a solar water heating system. In this week’s post, we’re going to identify the key characteristics of these three heaters, and what makes them beneficial above the competition.

First, have a look at the Guardian DHW Drainback solar water heater, and note the diagram listed on the page. You’ll notice that with this system, there is a heat exchange/drainback reservoir located between the solar storage tank and the solar heat collector panel. This drainback reservoir is meant to retain any circulating water flowing through the collector after water use has ceased. The purpose of this reservoir is to protect the water from being frozen during the colder months. As such, this system is ideal for installations in areas where cooler temperatures are common in fall and winter.

Second, check out the Guardian DHW Indirect solar water heater. In this diagram you’ll notice that there is no drainback reservoir, and instead of water, the unit uses a unique heating solution contained within copper coils that line the holding tank. These copper coils transmit the heat collected through the collector panel ‘indirectly’ to the water, by way of the heating solution. As with the other two types of water heating systems, the indirect solar water heater is one of the most efficient units in the industry.

Lastly we have the Guardian DHW Direct solar water heater, which is the most straightforward and simple solar water heater available. It doesn’t use a heating solution and copper coils like the indirect system, and delivers heated water directly from the collector panel into your home for immediate use.

So which solar water heating solution is right for you? To answer this question, just contact us at The LeverEdge and we’ll ask you all the necessary questions to arrive at the optimal system for you.
