Get hot water back with the Balboa VS100 4.0kW Flo-Thru heater assembly, part 26-58203-K.
This compact heater has a 10 inch by 2 inch body, shorter than the common 15 inch heater. Measure your old heater first, since length decides whether it fits your plumbing. Questions? Call 631-678-6506.
How to choose and fit the VS100 4.0kW Flo-Thru Heater Assembly
Measure the length of your current heater body and confirm it is 10 inches, not 15.
Check the 4.0kW rating and the 2 inch size against your old unit.
Turn off power, drain the line, swap the heater, and call 631-678-6506 before you power up if anything looks different.
