Cleaning

  • Scale builds up on the inside of pipes, and must be cleaned every year with mild acid such as vinegar

Sourcing

  • 4.1 kW 100F rise recovary rate of 30 gph - stated spec. $330 [1]. Q&A is inconsistent with spec: [At 0.5 GPM you will receive a 56° temperature rise, at 1.0 GPM you will receive a 28° temperature rise]. It's tiny - 10x5x3 inches.
  • 8kW 35F rise at 1.56 gpm - $240 -[2]
  • 6.5 kW 30A 240 - $120 [3]
