The price of
the average tankless water heater can range from $1200 to $3000. We
would recommend browsing the many retailers you could find online.
Determine what type and brand you need. Simply answer this question,
what you are using the tankless water heater for, home, apartment
building, or industrial?
Here is a bit of information:
SOURCE: Consumer Energy Information: EREC Reference Briefs
A Tankless water heater will cost more than conventional storage
tank-type units. Small point-of-use heaters that deliver 1 gallon
(3.8 liters) to 2 gallons (7.6 liters) per minute sell for about
$200. Larger gas-fired tankless units that deliver
3 gallons (11.4 liters) to 5 gallons (19 liters) per minute cost
$550-$1,000.
The appeal of a tankless heater is the elimination of the tank
standby losses and the resulting lower operating costs, as well as
the heater delivers hot water continuously. Gas models with a
standing (constantly burning) pilot light; offset some of the
savings achieved by the elimination of tank standby losses with the
energy consumed by the pilot light. Much of the heat produced by the
pilot light of a tank-type water heater heats the water in the tank.
Most of this heat is not used productively in a demand water heater.
The exact cost of operating the pilot light will depend on the
design of the heater and price of gas. This could range any where
from $12 to $20 per year. Ask the manufacturer of the unit how much
gas the pilot light uses for the models you are considering. It is a
common practice in Europe to turn off the pilot light when the unit
is not in use.
An alternative to the standing pilot light is an intermittent
ignition device (IID). This resembles the spark ignition
device on some gas kitchen ranges and ovens. Not all demand
water heaters have this electrical device. You should check with
the manufacturer for models that have this feature.
