Tankless Water Heaters - Why You Want One

Tankless water heaters provide an endless supply of hot water whenever and wherever you need it. Even if you are doing multiple tasks at one time you will never run out of hot water again. Tankless technology features copper heat exchangers to provide maximum efficiency and uses up to 40 percent less energy than a traditional tank. Every part of a Tankless Water Heater is replaceable. Components can be easily exchanged, if needed, versus replacing the entire system. The units come in multiple sizes so a plumber such as JMS Express Plumbing in Los Angeles can help you choose the right size and efficiency for your home. How does it work? 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 model. The PC board is then signaled to activate the flame igniter or ignition. 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. 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. 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 the desired temperature. 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 in the system How does a Tankless Water Heater save energy? By operating only when hot water is needed, and with no storage tank to heat and reheat water, tankless technology helps save on energy and utility costs. The use of an electronic ignition means no standing pilot light that constantly uses energy. What is the Lifespan of a Tankless Water Heater? A typical tank water heater is supposed to last 10 to 13 years, tankless water heaters are estimated to last up to 20 years. If you're planning to stay in your home for a while, that's a hefty replacement fee you're saving. Even if you're not going to stay in your home for that long, it's nice to pay it forward towards the overall cost savings of home ownership.
