Solar Backup Booster

Tankless hot water boosters can be a great way to ensure the performance of your solar water heating system.

With more and more people looking to utilize greener technologies, hot water heating continues to come to the forefront of the sustainability movement. The cost of heating water can be the second largest utility expense in the home, often running between $400 and $600.

One common way of heating hot water that has recently emerged is solar hot water heating. These solutions are advantageous because they are able to leverage the power of the sun to heat hot water, greatly reducing the need to use expensive fuels like oil, coal or natural gas. Unfortunately, because solar hot water heaters are dependent on the sun, they require backup systems in case of cloudy days or times when hot water demand is high.

Why tankless?

Tankless hot water heaters can be the perfect back up system for such projects, because of their ability to save on a number of different fronts.

  • Energy: Tankless solutions heat water on demand, meaning they only use energy when it is needed. Other solutions, like hot water tanks, waste energy constantly keeping water at a certain temperature.
  • Space: Tankless water heaters can be mounted on a wall or underneath a sink. They are 90 percent smaller than tanks.
  • Water: Tankless water heaters can provide hot water immediately, rather than you having to wait for it to heat up.
