These reviews are for systems that use a heat exchanger to separate the heat transfer fluid from the domestic hot water. These system are typically used in climates that experience freezing outdoor temperatures.

World's Best Solar Water Heater :

Our top selection for a solar water heater is from BAXI which is a part of BDR THERMEA. The SOLARFLO systems use adjustable differential temperature regulation to maximize your solar savings. The collector kits are available for integrating into the roof, mounting on a sloped roof, mounting on a flat roof, and in evacuated tubes instead of flat plate collectors. The systems are backed by a very good guarantee.

These systems are made and sold in the U.K. The standard kits do not include the storage tank but they do offer to include them. The warranty on the kits is not very good when compared to other brands.

This brand is from ALPHA HEATING INNOVATION which is a part of IMMERGAS GROUP and is available in the U.K. The SOLARSMART kits use a drainback tank for freeze protection. They have a patented "solar valve" which sends water directly from the solar heater to the tap, if the temperature is >60C. If the temperature is <60C, the water is sent from the solar heater to the combi boiler for further heating. The collectors can be mounted in the roof or on the roof as well as used on flat a flat roof. The brand has a good guarantee on the collectors and the tank but not the other parts.<1*

This brand is a part of AO SMITH. The standard systems include the basic parts for installing the system while the deluxe packages include the materials such as flashing, etc. to install the panels on the roof. The systems are available in sixteen different configurations to suit just about any need. The warranty is very complicated and the guarantee on parts (except for the storage tank and panels) is not as good as many other brands.
