Does anyone know the pros and cons of a comfort pump for immediate
hot
water? I've been checking out the tankless types and the cost is
reasonable for the unit, but almost prohibitive for installation.
Then
I saw a flyer on these comfort pumps, where you install just below
any
sink a valve..no electricity required and the main pump on top of
your
existing water tank. With the tankless ones, one has to update a 100
amp main ( in my case ) to 200 amp and that does not include the
plumbing installation.


Look here for a description of the Grundfos one-I saw it a while back
in JLC magazine:
