Cheap Tankless Water Heaters

Thanks to government subsidies, tax credits, tax rebates and sometimes additional local utility rebates tankless water heaters can compete favorably with the old fashion tank water heaters. Their initial cost has come down and the payback on energy savings can be very substantial.

According to various statistics 30% to 40% of the energy cost of a typical home is consumed by the water heater. Tankless water heaters can reduce that by more than 50%. Tankless water heaters are also popular for commercial and industrial applications. Models like Noritz 751, Noritz 842 and Noritz 931 can be installed in series to provide almost boiling water.

Restaurants, Hair Salons, Gyms and many other commercial businesses can benefit from the energy savings of tankless water heaters in addition to the space savings. Smaller units like Noritz 631 are well suited for smaller applications, like apartments or smaller homes. Most units allow you to set the desired temperature via a control panel that can be conveniently installed in the bathroom or any other place. This gives you immediate control of setting the desired water temperature.

There may be times that there is a need for higher temperature of 180 degree F for example, this is easy to set through the digital control panel. This is very useful when filling a SPA or filling a large bath tub.

Because tankless water heaters are sophisticated appliances the more critical is their correct installation. They should be installed by licensed, factory certified and experienced professionals. By far the most installed type of tankless water heater is the one powered by natural gas. Electric models are not very economical because of mostly higher electric rates and potentially higher installation cost. Electric units usually have a high power demand and may need supply circuits of 100 or more amperes.

This would require an upgrade to the existing electric system of the house that becomes costly. Smaller electric tankless water heaters can be easily used in point of use locations, for example for the kitchen sink. They require much less power.

The most important factor is the location where the tankless water heater is going to be installed. It is crucial to be close to the gas meter and the gas line to be properly sized so it is able to supply the volume of gas needed. Utility gas meters can also be restrictive and not able to supply enough gas. This is usually not a problem, most utility companies can exchange the meter free of charge. Since the tankless water heater modulates its burners it adjusts the gas flow to the burner for desired temperature.
