Energy Saving Tankless Water Heaters
Get On-Demand Hot Water with an Energy
Savings Tankless Hot Water Heater

One way to combat high home energy bills is to switch
from the conventional hot water tank heating system to an energy
efficient tankless water heater. Tankless water heaters operate
differently than the conventional hot water heating system by the
simple fact that they do not use a tank to hold heated hot water.
Instead, with tankless water heaters, the water is heated as it is
needed. For example, when someone turns on the shower, cold tap water
is pumped through a large heated coil in the tankless hot water
heater. As the cold water works its way through the coil it is warmed.
By the time it reaches the showerhead it is at the desired temperature
level as set on the tankless water heater. |
Tankless water heaters are compact, extremely efficient, and
somewhat complex. As a result, they are more expensive to install than the
traditional hot water heater tank. However, the extra cost for installing an
energy savings tankless water heater is quickly recovered by the monthly savings
in hot water heating bills.
In theory, tankless hot water heaters also never run out of hot water. But this
said, each tankless hot water heater is designed to produce a specified flow
rate. Exceed this flow rate and you may end up with lukewarm hot water showers.

The flow rate is expressed in gallons per minute of hot water.
In addition, tankless hot water heaters also specify how much they
can raise the water temperature from input to output, at a
specific flow rate. What this means is that during warm summer
months you’re likely to produce a hotter water temperature for a
specific flow rate than during the winter months, when the input
water temperature is usually colder.
The most efficient tankless water heaters operate off of gas.
Besides gas being an extremely efficient fuel source it also has
the capacity to heat water very quickly. The only two draw backs
associated with using gas, is that gas is often more expensive
than oil, and a gas operating tankless water heater requires very
good venting.
|
Often a powered vent system is installed when installing a gas
fired tankless water heater. For very small hot water heating
systems there are also electric tankless hot water heaters.
However, electricity is typically a very expensive energy source.
So if in the market for a new hot water heater, look at energy
saving tankless water heaters. A tankless hot water heater may be
just the ticket for your hot water needs.
