Cheap Tankless Water Heaters

Tankless water heaters are new in the US, compared to Europe and Japan. It was only recently that they became popular with homeowners.

One of factors that attracted homeowners is that Tankless Water Heaters provide hot water only as it is needed. That means these water heaters use energy only when hot water is being used. This makes homeowners happy as using tankless water heatermeans less energy consumption. This way these water heaters help save you more money than their initial cost over their expected life of about 20 years.

Tankless water heaters offer more flexibility in terms of possible applications and save space as compared to conventional storage water heaters. A typical model needs much smaller space, and is easy to maintain. Some of the tankless water heaters can be vented horizontally or vertically into the existing chimney. They often generate a continuous, unlimited supply of hot water for the least energy use. Because there is no storage tank to heat, instead they heat water directly

Another feature of tankless water heaters is their ability to produce a set amount of gallons of hot water per minute at a given temperature increase. Sizing Tankless water heaters are determined on the basis of gallons per minute (gpm) of flow of hot water.

If you are taking a shower and someone demands hot water at a sink or other shower, the system automatically adjust it to compensate for the changes. They have a flow switch built into them. As a result, Tankless Water Heaters deliver a constant supply of hot water .There is no fluctuation, no temperature drop, just endless hot water.

However some smaller Tankless Water Heaters cannot supply enough hot water for simultaneous, multiple uses in large households. In such case, you can install a whole house type Tankless Water Heater or install two or more Tankless Water Heaters, connected in parallel for simultaneous demands of hot water.

You can also install separate Tankless Water Heaters for appliances, such as a clothes washer or dishwater, that use a lot of hot water in your home. For homes that use 41 gallons or less of hot water daily, Tankless Water Heaters can be 24% – 34% more energy efficient than conventional storage tank water heaters.

Advanced tankless water heaters have computer-monitored safety devices and automatic water and gas valves. However there is no industry standard for testing and rating the efficiency of tankless water heaters. Also, the heating elements and gas requirements for tankless water heaters are much larger than those for conventional storage water heaters. Standard electric water heaters typically require a 25- to 30-amp circuit breaker, whereas tankless water heaters require 50- to 60-amp circuit protection.
