Drainback Solar Water Heater

Regardless of what the heat is being used for the basic components of a drainback system are.

Drainback solar water heater.

One version of the drainback system has been in continuous operation since the late 70s. Traditional drainback systems use a pump to circulate water or glycol in the collector loop which drops into a reservoir tank when the pump stops. The drainback solar water heater is recommended for all climates even the coldest since it drains the fluid out of the collector and exposed pipes. A residential drain back solar hot water system.

A storage tank to hold the end use water being heated. A differential controller which monitors the water temperature. It is scalable to any size from the smallest residential system to the largest commercial system. This is the reason why the system must be designed in a way to drain the fluid fast and thoroughly.

Drain back tanks are ideal when designing solar thermal systems especially in climates that exhibit very hot or cold temperatures. This could be a domestic hot water tank a. It has the following six fundamental characteristics. One or more solar hot water collectors.

A drain back tank allows all the water from solar collectors and related piping connections to drain into the tank reservoir protecting the system from both freezing and overheating.
