Solar Panels on Roof
  • How do solar water heaters work?
    Strategically placed solar panels, also known as photovoltaic (PV) panels, are used to convert sunlight directly into electricity. The generated electricity is then used to power an electric heating element in the water tank. When the electricity flows through the heating element, it generates heat, which is transferred to the water in the tank.
  • What are the benefits of using a solar water heater?
    Using a solar water heater can help reduce your energy bills, lower your carbon footprint, and increase the value of your home. It is also a sustainable and environmentally friendly way to heat water for a low initial cost. Once you have paid for the installation, you will be able to heat your water for free, for life.
  • Is the Apparent Water Heater safe and easy to install?
    The Apparent Water Heater provides a secure and standards-compliant platform. It is easy to install and is designed with user safety in mind. It uses low voltage circuitry (below 60VDC), requires minimal plumbing and basic electrical knowledge to install.
  • What is the maintenance required for a solar water heater?
    Solar water heaters require very little maintenance, but it is important to have them inspected and serviced periodically. This may include checking the system for leaks, cleaning the collector, and replacing any worn or damaged parts.
  • Are there any government incentives for installing a solar water heater?
    Yes, there are government incentive rebate programs that you can apply for that will significantly bring down the cost.
  • Can a solar water heater be used in cold climates?
    Yes, solar water heaters can indeed be utilized in cold climates. The Apparent Water Heater, equipped with cutting-edge features, demonstrates remarkable adaptability by requiring only a minimal amount of sunlight to generate hot water. Additionally, it is worth nothing that solar panels exhibit enhanced performance in colder temperatures, thereby offering potential advantages in cold climate conditions.
  • How long do solar water heaters last?
    Solar water heaters have an impressive lifespan of 10 to 15 years or even longer when properly maintained.
  • What is the environmental impact of a solar water heater?
    Solar water heaters can significantly reduce the carbon footprint of a home by reducing the need for electricity or gas to heat water. This can help reduce greenhouse gas emissions and combat climate change.
