HOT WATER FROM THE SUN FOR LESS

HOW SOLAR WATER HEATING WORKS

A closed loop system utilizes a propylene glycol liquid to protect against freezing and hard water. The sun warms liquid in the solar collector on the roof.
The liquid is pumped down to the solar tank where the heat exchange transfers the heat to the domestic water.
As you use hot water in your home, the hot water in the solar tank flows into existing water heater. Because the water is already hot, your water heater doesn’t have to work as hard.
The solar station monitors the temperature of the liquid in the collectors on the roof compared to the water temperature in the solar tank and continues the transfer process until the desired temperature is reached.
The solar hot water is ready for use in the home.

5 Things to know about solar WATER HEATING

How would you attach panels to my tile roof?

Aztec uses tile roof brackets that does not penetrate your tile. We simply remove a tile to insert a tile roof bracket which sits on the top lip of a tile. We then reinstall the removed tile. The tile roof bracket then used to attach our panels to.

How long does the install take?

Typically a system will take one day to install. In some circumstances, it may take a few days depending on the difficulty of the job.

What about roof damage?

Aztec Solar has been installing on different kinds of roofs since 1980. We have experience on all roof types. We guarantee our craftsmanship work and carry insurance, licenses and bonds to protect the homeowner.

How much water does it hold?

A home’s average water heating tank is 50 gallons, whereas the average solar back up storage tank supplies 80 gallons of sun heated hot water. This means plenty of hot water for the showers and the laundry.

How efficient is solar water heating?

SWH panels are between 70%-90% efficient, compared to between 16%-24% efficient for solar photovoltaic (electric) systems. No inverters are needed for SWH, the sun’s energy directly heats the water- this is the main reason for why SWH’s efficiency is higher.
