I have decided to get point of usage tankless water heaters.
Considering everything, the best deal for me with my usage needs will
be from home depot. They have 2 gallon per minute units that are all
electric for less than 200 bucks each. Since I am almost done with
redoing all pipe with pex and all fittings under the sinks, all units
will easily fit under them also.
The other main deciding factor was cost and savings. Larger units
in gas for under 500 bucks only had an efficiency of 64 percent for
whole house usage. The whole house electric units would run cheaper
than gas at such a low efficiency. It seems almost a sin to buy a unit
or offer a unit to say "save" and offer only 64% efficiency. Best
deals on gas units start at over a thousand bucks. Best units if money
is not a problem start near 3 grand each.
If I don't do anything right away the deals will change and I'll
have to re-check at that time. But point of usage units for my life
style will be the most cost effective and generate the greatest power
and water savings.
