When mounting collectors make as few roof penetrations as possible.
Install a shut off valve for the solar system so that the cold water supply is not interrupted.

The drain line should be discharged the to the outdoors no higher then 6 above grade.
Most solar hot water collectors are similar in shape to photovoltaic solar panels and also will lie flat on your roof.
Until now most solar hot water systems have required professional installation with a price tag of 4 000 to 8 000.
In some cases the collectors can be mounted on a roof and the piping run through a vertical wall instead of through the roof.
Solar pump controls.
Seal all roof penetrations with silicone sealant.
Solar heat exchange tank.
Mount the solar collectors on the roof.
