4 gpm tankless electric water heaters will work great in an
average home with several hot water fixtures. You may compute the capacity of
tankless water heaters by adding the required gpms of your appliances and
fixtures that require hot water. For instance, you have a shower, which needs
an average of 2 gpm; a kitchen sink that requires about 1 gpm, and a dishwasher
that needs 1 to 3 gpm. The total is 4-6 gpm. So, if you are only using a 4 gpm
tankless electric water heater, you may experience heat fluctuation if you use
these fixtures simultaneously. If you have a washing machine, that will need
more hot water and you might not be able to use the rest of your hot water
fixture if you are doing the laundry.
On the other hand, if you have decided on a 4 gpm unit, then
you have to make sure that it works as it promised. It must give you 4 gpm of
hot water; any less will positively give you cold showers in the morning rush.
So, how can you make sure that a 4 gpm tankless electric
water heater works efficiently? Look for these things:
·
Reliable water flow. Don’t settle for 2 gpm flow
if you are promised with a 4 gpm output.
·
Durable and high quality materials. For utmost
efficiency and longer operating years, make sure the materials used in your 4
gpm tankless electric hot water heater are durable.
·
Rust-proof body and pipes. Rust and
corrosion-proof parts prevent early damages.
·
High thermal efficiency percentage. Ensures that
you get your desired temperature output.
·
Easy to maintain. Since you need to maintain
your tankless water heater unit, getting a model that is easier to maintain is
ideal.
·
Cleans itself. Self-cleaning features are now
available in most tankless units, so make sure to choose a model that has it.
