Electric Tankless Water Heaters

Whole-house and point-of-use tankless and mini-tank electric hot water heaters in hardwired and plug-in options.

Types of Electric TWH’s

Whole-house tankless units are intended for whole-house, multi-fixture applications.
Point-of-use or "under-the-sink" electric tankless water heaters are compact units designed for single-fixture use, most commonly for a kitchen, laundry, bar or bathroom sink.
Mini-tank electric water heaters are not considered true "tankless" since they incorporate a small storage tank. However, due to their relatively small size, they are also classified as under-the-sink water heaters and are intended for single fixture applications.

Sizing an Electric Tankless Water Heater

An electric TWH is sized based on GPM hot water output the unit is capable of providing at a given temperature rise (difference between output hot water temperature and incoming cold water temperature).
Availability (uptime) and abundance of electricity are also important factors, especially for whole-house units, which usually require 208-240V power supply and several dedicated high-amp breakers.
