Solar water heater ratings part 13 continues our expert and unbiased reviews with a look at the Solene, Sol-Reliant, Sonnenkraft, State, Stiebel Eltron, Strebel, and Sunchi brands.
This brand is from UMA SOLAR and offers both open and closed loop systems as well as drainback systems. Their SIMPLE DRAINBACK system is an inexpensive option that is easy to install as it keeps the system basic. The systems are sold through dealers and the manufacturer's website is not much help.
This brand is from MR. SUN SOLAR and offers kits that are shipped worldwide for the do-it-yourselfer. They have a built-in photovoltaic panel and a dc pump to provide the electricity that is needed. They use a 80 gallon storage tank that is made by RHEEM but the kit does not include the copper connecting pipe or the antifreeze (glycol). For the most part, the warranty is good but the guarantee on the collectors is not as good as many brands.
These units are made by GENERAL SOLAR SYSTEMS which is a part of the SOLARCAP GROUP. The COMPACT system is a basic water heating system while the COMFORT systems provide hot water for the central heating system as well as the domestic hot water. They use the more efficient evacuated tube collectors but the manufacturer's website is not much help.
The PREMIER range of solar water heaters features 16 different package combinations to match the specific needs of the home. They feature CHROMAGEN brand collectors which are backed by a good warranty. The other parts of the package do not have a very good warranty and the systems are only sold and installed by authorized dealers.
