Whole-Home Electric Tankless Installation in Boston
Whole-home electric tankless units can supply multiple fixtures at once when properly sized. Models like the Stiebel Eltron Tempra and Rheem RTEX often require multiple dedicated 240 volt circuits.

Complex installations or higher-capacity units can be at the higher end of this range.
Water hardness varies from place to place. Much of the public water in Massachusetts is soft and slightly acidic, which is easy on fixtures but can gradually wear through copper pipe.

We can advise on maintenance and offer water softening solutions if needed.
Most electric tankless water heater installations can be completed within a single day, usually 4 to 8 hours. However, if major electrical panel upgrades or extensive re-piping are required, the process may extend into a second day. We aim to minimize disruption and restore your hot water as soon as possible.
In most areas, permits are typically required for electric tankless water heater installation, particularly due to the electrical work involved. Massachusetts writes its own statewide plumbing code instead of adopting a national model code, and it is known for being strict. BWM Plumbing handles all necessary permit applications in Boston and makes sure the installation passes all required inspections.
