I provided two separate invoices. First invoice was to remove existing 50 gallon water heater and install a new Rheem tankless 27. Second estimate was provided and install a ream 55 gallon 4500 W water heater. Along with pedestal sink faucet change out and minor toilet rebuild.. At this time, customer is not ready to sign estimate until she knows how much it’s going to cost from an electrical company to upgrade the breaker and wire for the tankless.
