How to Use an On Demand Hot Water Heater
On-demand hot water heaters, sometimes called tankless hot water heaters, have been used for many years in Europe and Asia. With this long manufacturing history and the resulting innovations, modern on-demand hot water heaters are very easy to use. Once properly installed, both electric and gas on-demand heaters work in very much the same way. However, some people feel more comfortable turning the gas off on tankless gas heaters when they are installed indoors. You might have to turn the gas on before using these types of heaters. Does this Spark an idea?

1
Turn on the water and allow it to run for one or two minutes to check the temperature of the water.
-
2
Use the water temperature control on the heater to adjust the flame level of gas heaters or the heat level of electric heaters. This control can be a knobs on some heaters, or digital controls on a more modern heater.

Adjust the flow of the water. Reducing the flow of water will allow it to stay in the heating section longer. This will result in hotter water. Increasing the flow will make it pass more quickly through the heating section, thus reducing the heat of the water. This control can be a knobs on some heaters, or digital controls on a more modern heater.

Use the water as you would from any other heater.

Tips & Warnings
Although adding cold water can slow the flow, you can add a little if the water is a bit too hot.
Adjust the temperature of the water by adjusting the heater, not by adding cold water. Adding cold water can slow the water flow through the on-demand heater, causing it to stop heating water.
Because of a tankless water heater's dual controls-one for flow, the other for heat-it is possible to slow the flow while turning up the heat to the point that the water in the heater may boil or turn to steam. Be very careful about turning the temperature of the heater up while restricting the flow. This can, in some cases, result in steam and dangerously hot water.
