Designed for cooler climates and all weather conditions, where it is likely you will need to use your booster more often. This Ground Mounted Solar Hot Water heater, with gas booster, still has its tank mounted on the ground to reduce structural load on the roof and keep a low-line roof profile.
Again in an emergency, where a replacement is required, you can run this water heater on its inbuilt gas booster until your new collectors are installed.
