Is a Tankless Water Heater the choice for you?

Tankless Water Heaters work to produce hot water as needed. A simple example of this would be: if you only need one gallon of hot water, a Tankless Water Heater will only produce (heat) enough hot water for one gallon. Unlike conventional tank-type water heaters that will continue to keep their tank’s capacity of water continually heated to the temperature set on its thermostat. Think of a tank-type water heater’s thermostat being the same as a home’s air conditioner/furnace thermostat; when the temperature drops, the water heater turns on to reheat the water. The fact that Tankless Water Heaters only heat what hot water is needed will save gas or electric by only using the needed fuel/electricity when needed. In addition to energy savings, Tankless Water Heaters are more convenient when sized properly.
In tank-type water heaters, hot water is only available for the quantity stored, not needed. Should a tank-type water heater have a 40 gallon capacity, the amount of hot water available, at maximum thermostat temperature, is about 50 percent, or 20 gallons. As a hot water valve is opened for hot water to be drawn from the storage tank of a tank-type water heater, cold water begins to enter the tank and replaces the requested hot water. If the temperature of the stored hot water is thermostatically set for 120 degrees, once hot water is replaced by cold water, the temperature begins to cool; leaving less available hot water. In a Tankless water Heater, once the thermostat is set for 120 degrees, regardless of incoming water temperature, the requested water will remain at 120 degrees. This is helpful when continual hot water is needed during long showers, baths, and heavy use.
Being energy efficient and convenient, a Tankless Water Heater can be the right fit for anyone looking for a salutation to their current tank-type hot water needs.
