Having already gone through the method of researching tankless water
heaters and the makers I found some fascinating findings
that should be considered before one buys one of these sorts of
heaters. Some things that need be brought into the equation are common
sense issues while many others could be have not ever been given a
thought until stepping into this arena.
For the sake of today's discussion we'll forgo whether or not it's more
efficient to use electrical, gas or propane and leave the debate for
article. I am going to presume that you'll just use whatever you
now have for an application and get on with the more generalized
tankless heater points towards ponder.
First off, and this is one of those'common sense' items, you will
need to ascertain the usage for the heater. That is, how much hot
water will be needing to be consumed and when. For example, do you
live alone and shower at a different time than when the laundry is
running? Or, do you have three bathrooms and a laundry room that may all
be utilised simultaneously? There is a mighty big difference there.
Once that is's figured out you'll want to consider if the tankless water
heater will employ a employ a centralized system with many branches coming
off a main trunk or if you will need to run one line and branch off
to each usage as you go along. There are benefits to both. With the
first option you can break it into zones and not have hot water
running through the entire system just to reach the farthest point.
An item that's seldom thought of is the water temperature. And this
is an extremely important factor. For homes in warmer climates it's
not as big an issue , if you live in Michigan or new england where
the ground water temperature can be intensely cold a more powerful
unit could be in order. Obviously, it takes more energy to heat colder
water than warmer water and you definitely do not need to finish up with
halfhearted water as you made a decision to save a couple of bucks. An option to
this would be to run 2 tankless water heaters in parallel with each
sending hot water to the point of use.
A last point is the water flow rate. Sizing a tankless water heater
is decided by how cold the water is ( as previously discussed ) and
how fast the water is moving through the line. The slower the flow
rate the more time the unit has to work with the water in heating it.
Some folks have really installed flow restrictors in taps and
shower heads to help compensate for over the top flow rates.
Except for safety issues like where to install the unit or
exhausting a unit other than an electrical the majority of the other concerns
will be covered in the manufacturers materials. That's the basics for
a way to choose a tankless water heater. Again, they all perform the
same function, that's to only heat water when it's called for. So,
decide if you want gas, electric or propane and enjoy you new, lower
application bill! For more information and resources see my bio box below.
