I have an instant hot water heater under our office bathroom sink to
provide warm water for washing our hands. The problem is that
sometimes sand and sediment get into the instant hot heater causing
the water flow to be restricted. This causes the instant hot heater
not to turn on since the water flow is too low.
I like to install a screen or small water filter in front of the
instant hot water heater to filter out such sand and sediment. Any
suggestions? I saw some water filters at Home Depot but they all tend
to be an overkill for this application, since we don't drink the
The inlet to the instant hot heater is 3/8" comp.
I agree with your diagnosis Ed, but where do you find a $15 a year
filter? I have a Filterite PF01 & the filters are $90/6-- and take
2 a year. [best price I've found at 911water.com]
If there's a better price out there, I'm all ears.
The other part of the equation is if you do use something like
a small screen filter, how often will it have to be cleaned and
how effective will it be? Given that, I'd agree with the others
who say just use a regular cartridge filter.
Oh and I forgot to add, what about the cost of the on-demand
water heater? I would suspect it could have problems from
crappy water, so I'd tend to err on the side of a real filter for
that reason as well. You could save $25 a year on filters and
wind up having repair costs on the heater that are a lot more.
