500L split solar electric water heater

Our Solar electric water heater is complete with electric heater as backup, it is multi-function for working. When there is cloudy or rainy day, you can take  solar electric water heater tank  as a heater boiler. And once there is sufficient solar energy for heating water ,solar system works as solar heater.

Our solar electric water heater is high quality to meet the both electric heater and solar heater demand.

How does solar electric water heater work?

Split pressurized solar electric water heater is working by active working between solar electric water heater tank,flat plate solar collector by workstation which included a control system.

Flat plate solar collector absorbs solar energy and the heat is transfered to water tank through pump circulation.When temperature difference value between collector and tank reaches the setted valve,the controller active the circulation pump automatically for heat exchanging. An internal coil pre-installed in storage tank plays a rolf of heat exchanger, a heat-transfer liquid circulates through solar collector to tank coil for heat exchange between the closed loop and main tank water and an additional tank coil can be prepared for heating equipment or other pool ,room heating .

There are three solar electric water heater working systems which are divided by tank design ： 

First type: Storage tank without coil inside. The tank and solar collector exchange the heat by water, the system need circulation pump for running. And controller will play as the control brain for working.

Second type: storage tank designed with one copper coil, this coil is for solar circulation. solar collector conducts the heat by circulation pump to exchange the heat through storage tank coil. Usually circulation pipeline usually filling with anti-freeze fluid (glycol for example) as heat exchange media.

Third type: tank designed with two copper coils: one coil for solar circulation between solar collector and tank, the other one for heating equipment or space heating devices (such as connect to gas/electric boiler , and for floor heating system).

To choose the right type system and parts:

We will suggest you to tell me the installation location, any existing heating equipment. And then I will make a design for you.

Our solar electric water heater has a backup electric heater installed in solar water heater tank. Which can be  split working  or working by control system command.

Once there is no solar energy or not enough solar energy , the controller can trigger the command to active the electric heater working to heat solar electric water heater.

Besides the 500L system,we also offer range 100L to 1000L resident system. Commercial more than 1000L system is also available.
