While having a domestic solar water heater can save you money, you need to know the right one to install. Solar water heaters are available in many types. The common ones used at home fall under the following categories.

Evacuated tube collectors consist of single tubes connected to header pipes. Every single tube must be evacuated to reduce the loss of water from the bearing pipes to the ambient air. The collector also has different geometrical configurations. That means a user must mount it with a specific tilt angle to allow the heat pipe’s condensed internal fluid to return to the hot absorber.
