Tankless waterheater - the cost
Faster Hot Water....without running any water down the drain!
A tankless waterheater has pros and cons, just like everything else. It can supply an endless supply of hot water, and can save energy.
However, they are limited in the amount of hot water that can be produced at one time and they are more expensive to purchase than a conventional storage type water heater.
They also make it take longer for you to get your hot water, since they don't start heating the water until you turn on the faucet. This problem can be solved by using a specialized pump, which in combination with the tankless water heater, can get your hot water to you at less than half the time it would take running the faucet full blast.
A tankless waterheater also causes an increase in water
wastage since you have to let the water run longer to get your hot
water. This problem is also solved when using the specialized pumping
system. Water conservation is an important advantage to the pumping
system. One such system is the Chilipepper hot
water pump. With it you get both water conservation and convenience
benefits of faster hot water, and, an un-limited amount of hot
water.
Tankless water heaters cost more than conventional storage tank-type units. Small point-of-use
units that deliver 1 gallon to 2 gallons per minute sell for about $200. Larger gas-fired
units that deliver 3 gallons to 5 gallons per minute cost $550-$1,000.
The appeal of a tankless water heater is not only the elimination of the tank standby losses and the resulting lower operating costs, but also the fact that
a tankless unit delivers hot water continuously.
Gas units with a standing pilot light, however, offset some of the savings achieved by the elimination of tank standby losses with the energy consumed by the pilot light. Moreover, much of the heat produced by the pilot light of a tank-type water heater heats the water in the tank. This heat is not used productively in an instantaneous unit.
The exact cost of operating the pilot light will depend on the design of the heater and price of gas, but could range from $12 to $20 per year. Ask the manufacturer of the unit how much gas the pilot light uses for the models you consider.
An alternative to the standing pilot light is an intermittent ignition device. This resembles the spark ignition device on some gas kitchen ranges and ovens. You should check with the manufacturer for models that have this feature.
