Everyone has to start saving energy with a solar water heater in the near future because energy prices will continue to rise.

Two-thirds of the energy that is burned in the power plant is lost in conversion and transportation through the power grid. Solar water heaters can cut your electricity bill by one-third. The prices you have to invest in solar panels determines the time when you will start to save energy and money with your solar water heater.
Because a conventional solar water heater is produced in very small quantities it is marked up heavily. Selling thousands of our solar water heaters spreads the cost and makes each solar water heater less expensive. In many states your break even point is when you are done with the installation of the Solartrex solar panels.

We differ between the single or dual loop solar water heater

Single loop solar water heater

Warm water is lighter then cold water. It collects at the upper part of the storage tank. Cold water from the lower part of the storage tank is pumped through the solar water heater where sunlight is transformed into heat that warms the water. The warmed water reenters at the upper part of the storage tank.
Warm water is drawn by for example showering from the storage tank and is replaced with cold city or well water. Before warm water becomes depleted in a prolonged period of bad weather the electric heating wand heats up the stored water to the set minimum temperature.

Pro:
- Saves up to one-third of your electricity bill
- Most effective way to use renewable energy
- Easy to install and maintain
- Prevents thousands of tons CO²
- Inexpensive starts below $ 599
- Little to no running cost (with PV solar panel)

Contra:
- Manual freeze protection
- Overheating is controlled by the safety valve
(The Solar water heater panel must be drained before freezing)

Dual loop solar water heater
Automatic freeze protection with heat exchanger

In climates with temperatures below freezing you need to mix food grade antifreeze in the water going out to the solar collector. Since you do not want anti-freeze in your coffee or shower water, you have to separate the potable- from the freeze protected water. In one loop the anti-freeze water is first pumped through the solar water heater where it is heated up by sunlight. The sun warmed water then passes through a heat exchanger that transfers the heat into the potable water, that is pumped through the heat exchanger as well.
Before warm water becomes depleted in a prolonged period of bad weather the electric heating wand heats up the stored water to the set minimum temperature.

Pro:
- Inexpensive starts below $ 999
- Little to no running cost (with PV solar panel)
- Big savings compared to conventional heating.
- No pressure on solar water heater
- Easy to install and maintain
- Automatic freeze protected system
