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.
