What is Solar Hot Water?
Solar thermal systems use the heat of the sun to create hot water for your home or business. Water heated from these systems moves to a storage tank to use at any time, making your electric bill lower! Our solar temperature water heating systems are low-cost, long life, high efficiency water heaters that use the sun.
Solar thermal facts:
Americans consume approximately 2.5 quadrillion BTUs of end use energy annually and produce end user hot water costs of $20 billion dollars.
• Solar Thermal systems can provide 80-90% of a homes hot water demand.
• Hot Water consumption generally accounts for 20-30% of a house holds energy costs.
• International Renewable Energy has designed this system to so that the ROI (return on investment) for the end consumer is less than 3 years.
• The reality is that gas prices fluctuate and are not stable, heating water using electrical means is absurdly wasteful, and there are really no other ways available that are as economical as solar power.
• Solar thermal systems can provide hot water for up to 96 hours in extreme conditions such as heavy snow or clouds
Evacuated Tube Solar Thermal Systems
Frequently asked questions with evacuated tube solar thermal systems:
- Are these new?No, the technology is about 20 years old. The tubes were developed in Germany by Daimler-Benz Aerospace in cooperation with a solar energy research company.
• How can you tell if you have lost the vacuum?
All tubes now being delivered have a silvery coating on the inside at the bottom of the tube. When vacuum is lost, this coating depletes and the tube becomes clear. Older style tubes did not have this feature and you had to rely on observing a build-up of condensation inside the tube as an indicator of vacuum loss.

• Will the glass break in a hailstorm?
The tubes are manufactured and tested to withstand 35mm (1.38 inch) diameter hailstones. The glass is low-iron tempered glass that is 2.5mm thick.
• Can I heat my house with these?
Yes, provided that the home is well insulated, thereby having a low heat loss to the environment. There are no rules of thumb for sizing a space heating array based on square footage of a house. You have to know the heat loss, design temperatures, weather data, and solar radiation available to estimate the size.
• What is the life of a tube?
The statistical “mean life to failure” is 15 years.
