Water Heaters

According to reports from The US Department of Energy, homeowners can save in the vicinity of 30% every year by heating their water with propane instead of electricity. Did you know 15%-25% of a home’s total energy cost comes from heating water?

Traditional Tank Water Heaters:

A propane storage water heater delivers the same amount of hot water as an electric unit but it takes up considerably less space, plus it saves about 15% on total annual energy cost. Residential tank water heaters typically store between 20 and 80 gallons of hot water, usually at the factory setting of 120°F. The temperature can be adjusted up or down by a control on the unit. Tank water heaters are typically located in the garage, basement or attic. They install just like natural gas water heaters, using similar connections, space and venting requirements.

Tankless Water Heaters:

Tankless water heaters save energy because they heat water only as it is being used, giving homeowners an endless hot water supply of about 222 gallons per hour. There is no standby heat loss from traditional storage tanks and the flow rate is about three times that of an electric storage or heat pump water heaters. Tankless heaters are compact, taking up very little floor space and can be installed on the exterior of your home and business. The service life of tankless water heaters is up to 2-3 times longer than traditional tank water heaters.

How Tankless Water Heater Works

1. When the need for hot water arises by turning on a shower, washing machine, dishwasher or faucet, cold water enters the tankless water heater from the inlet pipe at the bottom of the unit. The PC board is then signaled to activate the flame igniter or ignition.

2. A combustion fan turns on to allow oxygen into the burner to ignite the flame as the gas control valve opens at a low frequency. Once an adequate flame is present the igniter stops sparking — beginning the next sequence of operation in a matter of seconds.

3. Water is heated as it passes through the coils of the copper heat exchanger, and exits from the hot water outlet pipe to travel through the pipes of the home or business to the water fixture where hot water is needed. For Condensing models, the water is preheated as it passes through a secondary stainless steel (latent) heat exchanger, capturing any extra heat (or latent heat) before it escapes into the vent system.

4. The gas valve and blower automatically adjust the incoming gas and oxygen to meet the water heating demands. If the demand is small, the tankless water heater can use a smaller flame and less gas. If the demand is greater, the flame can expand across the width of the entire burner to heat more water. The tankless water heater adjusts as needed to ensure the temperature set point is maintained. A digital controller allows the user to choose his desired temperature.

5. As the hot water fixture shuts off, cold water stops entering the tankless water heater and the flame diminishes. The combustion fan continues to operate at a low speed for a short period of time. This allows the exhaust of any leftover combustion gases.
