Additional options offered

  • Combine two hot water zones. This option allows hot water, in 2 separate parts of a house, to circulate as one zone  $375.

  • To remove (1) 50-gallon tank from first level inside attic of $100 

  • To  remove (2) 50-gallon tanks and $150 or the tanks can be left in the attic.

  • Hard to access attic area where the tankless is to be installed. $350  This is for extreme conditions where existing construction makes the tankless installation very labor intense, occurs only 3 % of homes.  

  • Due to the sediment, from old tanks, aerators and shower heads must be cleaned after the tankless system is installed. The sediment that has collected in the aerators and shower heads will reduce the hot water flow rate, which affects the hot water temperature. This task of removal and cleaning can be performed by the homeowner (see videos) or by our crew for $150.    

  • When adding the Crossover Valve, for the RHGH hot circulation system, we encounter "builder grade" sink valves or stops which are not compatible
    with the Rheem Crossover Valve. In this case we must replace the original water supply lines and valves or stops, under only one sink, to assure there will be no future leaks. Install new water supply lines and sink valves or stops  $195.  See pics below

  • For Tankless Guru to change your water filter $125. Includes labor and cartridge.


If you have sink valves or stops, that look these, they will need to
be replaced in order to install the re-circulation cross over valve.
