I have an old water heater (providing hot water on demand, not filling
a tank). This water heater is old and inefficient and needs replacing
as it has started leaking and finding the replacement part is
Anyway I reckon it is time to get a new one, can anyone recommend a
good water heater, wall mounted, providing hot water on demand for 1
bath, 3 sinks and a washing machine.
do you mind the delay bettween opening valve and getting hot water?
tankless must be sized to use and incoming water temperature.
in areas that get cold in winter incoiming water temperature dives,
you could get a regular tank unit for perhaps 400 bucks.
tankless will be at least several times that, and you must get one
that has local service, new tankless are high tech and require
knowledgable techs. just like high efficency furnaces new tankless are
more complex and more likely to break
Hallerb, He said he has a tankless so quit trying to put them down, as
I am happy with my Bosch tanlkess also, I have no more time delay than
at another location where I have a tank, they turn on when water flows
and my Bosch 117000 Btu was $460.00 I do fine with a Bosch 117000 btu
for one shower, if you are satisfied with the output then match the
btu. Going up will require gas line size increase. If its for one
person 117000 btu is fine.
Maintaining 40 or 50 gallons of hot water 24/7 in inefficient and
wasteful unless it's solar.
Demand water heaters are energy efficient and only heat what you use and
draw no power when not in use.
Higher capacity electric demand water heaters take excessive power and
you many not have enough coming in your house so it's not worth having
to upgrade the house electric just for that.
I have not had experience with gas demand hot water heaters but are
probably a good bet. I have had oil fired demand water heaters and they
work very well. You never run out of hot water and it only runs when you
draw hot water. Of course gas and oil need to be vented.
In my former apartment I had a Bosch that worked great once it got
installed. The landlady and her boyfriend did the install themselves
and it took them a very long time with lots of expletives, and once
they got it running they did have to call a plumber twice to fix a
couple things, but I chalk that up to the installation, not the
heater. I only had it for about a year before I moved, but I
absolutely loved it. I have heard some professional plumbers say that
Bosch tankless are not good quality, but not sure if that is based on
up to date info. Just be sure you get the right kind for your
climate. In northern climates there are some models that cannot heat
the water quickly enough in the winter.
