Homeowners are getting conscious of their carbon footprint and taking steps in order to go green, both by retrofitting existing structures or by installing more energy efficient appliances and fixtures. But one thing that homeowners usually oversee is how much their water heater affects their total energy use- in fact, most people don’t think about their waste heater at all; it gets installed in a closet and forgotten about as long as it’s working.
The problem with water heater is that even though a homeowner never thinks of it, it is still consuming energy to heat water 24 hours a day, 7 days a week- even when no one is really in the shower. All this unnecessary energy use adds up. Water heating is considered as the second-highest expense in a home, accounting for about 18 percent of a utility bill after heating and cooling, according to Energy.gov. The best alternative for this according to contractors is the best natural gas tankless water heater. It will improve the carbon footprint by saving energy and water- as well as help them pocket some extra cash in the long run. It heats water directly within the use of a storage tank. When a hot water tap is turned on, cold water travel through a pipe into the unit, and either gas or electricity heat the water.
Tankless water heaters can avoid the standby heat losses associated with heating and keeping hot water when not needed, and that can amount to 50% energy savings over a conventional hot water tank system, about $165/annual on the utility bills for an average household. However, gas fired tankless water that provides a higher flow- commonly have a constantly burning pilot that equals the savings to an energy efficient storage water heater that uses that pilot to keep water hot on stand by.
If you live in a high-demand household, you may want to consider installing two or more tankless water heaters, connected in parallel, or separate tankless water heaters for appliances- like clothes washer or dishwasher- that use a lot of hot water in your home. Those heaters are perfect to feed hot water to remote bathrooms or appliances.
