High Efficiency Water Heater Replacement
Energy savings depends on family size, water heater location, the size and placement of the water pipes. High efficiency water heaters use 10 to 50 percent less energy than the older standard water heaters. Energy star is the government-backed symbol for energy efficiency. It identifies new homes, buildings and more than 50 types of products that are energy efficient.
These products earn the ENERGY STAR label by meeting the energy efficiency requirements set forth in ENERGY STAR product specification
- Storage Tank Water Heaters - Water is kept hot and ready to use in the tank. They use electricity, gas, oil or propane. There is an endless amount of water that has to be kept hot, so there are standby losses.
- Demand Tankless Water Heaters - Water circulated through a large coil is heated only on demand using gas or electricity. No storage tank is used, but there is a limited number of fixtures that can use hot water at the same time. There a no standby losses with the tankless water heaters.
- Heat Pump Water Heater - Heat pumps transfer energy from air to the water in the tank. Heat pump water heaters are more efficient than electric water heaters. The water pump is best used in mild and hot climates.
- Solar Water Heating - The sun's energy is used, but requires a regular water heater as backup source when solar energy is not available. Solar heating is expensive but the savings are huge. They are best used in mild and hot climates.
