Tankless Water Heaters are the latest buzz in the USA, and
more specifically here in the Puget Sound region. While the
technology has been around for many years, tankless heaters hadn't been
widely accepted here in the USA until recently. There are many
reasons contributing to the initial lack of acceptance of the tankless
concept. First of all, there weren't many manufacturers who were
marketing tankless systems in the USA before the late 90's. The
few systems that were available were not powerful enough to be used as
a "whole house" type heater. In other countries, tankless water
heaters are (and have been) widely used, but are typically installed in
a "point of use" fashion. A typical house will have several
heaters installed in the areas where hot water is used. Point of
use works well if the water supply system is laid out as such when the
house is built, but the standard layout in the USA builds the home
around one hot water source. Contractors quickly lost
confidence in the tankless concept after trying to make a point of use
heater work in our common "whole house" layout. This lack of
confidence trickled down to the customer, thereby stalling the
advancement of the tankless water heater home.
Now, companies offer tankless heaters that will supply
enough hot water for the "whole house" application. The one
common denominator in the whole house concept is that these heaters are
GAS FIRED. We get a lot of calls each week from customers who
like the tankless concept, but do not have (or want) natural or liquid
propane gas at their home. There are electric tankless water
heaters available, some of which will work very well in the right
environment. However, the
electric tankless water heater will not work for MOST "whole house"
applications. The most powerful electric tankless water
heater is limited to about 2-3 gallons per minute of hot water in the
Pacific Northwest climate (This is based on an average. Expect more GPM
in the summer, as the incoming water temperature is typically higher,
therefore less degree of rise is required, and vice versa for
winter). When you also consider the electrical requirements for
this type of electric tankless heater, it is easy to see why they are
not widely used. These heaters require 3 separate 240 volt, 40
amp circuits, each with 8 gauge conductors. That's 120 amps
total, just for the water heater. Most homes will need extensive
electrical work to meet this requirement. (an average electric
tank heater requires one 240 volt, 30 amp circuit, with 10 gauge
conductors)
Who is a good candidate for an
electric tankless heater? The ideal candidate will have a
smaller home, probably 1 or 2 bedrooms, 1 bathroom, and not more than 2
people living at the home. Electric tankless models are also
popular with owners of vacation or remote cabin type homes. These
homes aren't typically lived in every day, and the tankless concept
eliminates the worry of a leaking tank style heater while the owner is
away. Cabin owners also tend to shut down the water heater while
they are away, and a tankless heater eliminates the need to wait 2-3
hours for hot water when the owner returns and turns everything back
on. Another benefit is the compact size of these models.
They are very small, and can be mounted just about anywhere.
(typical size is about 16x16x 5 inches). For those interested in
the electric tankless water heater, we recommend you check with your
electrician to see if the electrical requirements can be met within
your budget.
