This system’s amp draw may be a bit high; therefore, it might not be ideal for every home.  So check on your home’s electrical service’s current size to find out if it can contain your water heater. You can do this by checking on the electrical breaker box or looking for a label on your electrical panel. You can also consult your electrician.

Water pressure requirement

Knowing your water pressure range is essential and helps you to plan early.  Most of these heaters work at a water pressure range of 30-150psi. So any pressure range above 150psi may require an additional installation of a pressure reducing valve.
