      You can, but not as a heat pump so you wouldn’t get all the efficiency gains and it will very often end up being more expensive to run than gas tankless in the near term.

      The more and more hot water spouts you have the more expensive the tankless design is, especially for running costs and short life span. The recirculating with a water tank will last longer, cheaper running costs, and can be fitted in already existing infrastructure of water tank designed homes. In building a new home, it is possible to have tankless water heaters be better than water tanks. especially if you can use Solar Panels to make the running costs near 0.

      My coworker bought one and had to buy a new electrical panel because it required 45A of electricity to run it meaning 3 dedicated circuits at 120V (5400 watts!). IMO an electric tankless is the worst of both worlds.
