Water Heating

Water heating has more options than ever!

Remember the days when your water heater was a large tank, in a garage, closet, or somewhere else, taking up potentially valuable storage space? Well those days aren't a death sentence anymore.

Water Heating has become a hot button item in today's energy efficiency discussion. Water heater efficiency has improved on both tanked and tankless designs, so the amount of energy spent heating the water to your desired temperature has reduced across the board. There have been sweeping changes to the ways water is heated in homes today.

Most homes have moved to the tankless water heater design. While the idea of removing the tank from the water heater seems like a great idea for energy efficiency, since we no longer spend energy throughout the day heating a tank of water over and over again, it doesn't have the desired impact on fuel consumption in many circumstances. The true value of a tankless water heating system is the ability to control temperature more accurately, and the idea that hot water is forever. The water heater heats ground-temperature water to the desired temperature as it flows, requiring a tremendous heat source, usually a factor of 5x that of a tanked water heater. So tankless designs are more about comfort than they are about energy savings. Many homes find that a tankless water heater actually increased their gas consumption for heating water, as they were now taking longer showers, using 300 gallon jacuzzi tubs more often, all because they had more hot water than before!

Solar Thermal water heating systems have even started to see an uptick in popularity recently. Solar Thermal systems use a glass panel (or two) on the roof, and run the water through the water coil on the roof, allowing it to absorb all the sun's energy, heating the water to temperatures over 120F. This is a very efficient way to heat water when there is even moderate sun, as the only cost associated with heating water this way revolved around the energy consumed by a small water pump that keeps the water cycling to the roof in order to heat the water in the tank.
