Answer: 
This mostly depends upon your incoming water temp (see the map in the product descriptions for an estimate). You will not be able to run this from the same power that you used for a tank water heater as it requires more power. If you run this 27KW unit it will require 3 2pole 50Amp breakers (6 power wires and 1 common ground).

Answer: 
Not nearly. You need Three (3) 50 amp double pole breakers. This takes up 6 spaces in your electrical panel. You have to have at least a 200 amp service panel.

Rated 3.0 out of 5 by 2 reviewers.
Rated 1.0 out of 5.0 by Marey Tankless I purchased the Marey tankless water heater at a great price as a daily promotion. The great price does not really matter because I could not install the unit and it was returned. The reason I am returning this unit is because the electrical demands on this is greater than the load possible for my home which is 200 AMP. Most homes are either 100 or 200 AMP. I consulted with several electricians and the majority said installing this unit will trip the main circuit breaker. Before you buy make sure your home can handle the amount of amperage required. The purchase was also not great. The vendor sent me the wrong shipment info and indicated the order was cancelled. I found the mistake of the wrong shipment info when I contacted Home Depot.

Rated 5.0 out of 5.0 by Great Item, love the fact that I use almost no electric when the unit is off The Water heater is great, install is a major pain in the neck, since you need to upgrade the electric to a much higher amount, but overall a good product and you get back a bunch of floor space when you replace your tank type water heater April 18, 2015
