Undersink Electric Tankless Heater

The Chronomite CM-20L/240 is a compact electric tankless water heater designed for undersink installation in residential or commercial settings. It operates on 240V AC single-phase power and delivers hot water on demand without a storage tank. The unit activates at a minimum flow of .2 gpm and provides a maximum flow rate of 1 gpm.

The unit measures 6.25 in high, 9.63 in wide and 2.75 in deep for indoor mounting. It frees up space compared with tank heaters but needs a dedicated circuit rated for the stated current.
