Overview
An electric heating element warms water as it flows, so this Chronomite Labs unit has no tank to keep hot. It mounts under a sink in a compact copper and stainless housing and feeds hot water right at the tap on a household voltage circuit.
Hot water at one sink without running a line from the main heater is the reason to install it. High efficiency and a small housing suit tight cabinets. Flow rate is not listed, which decides whether it handles a hand sink or a busier faucet.
Who it's for
Remote bathroom or office sinks with long hot water waits are the classic fit. Whole-house or shower use needs a much larger heater.
Pros and cons
- No tank to keep heated
- High listed efficiency
- Small under-sink footprint
- Copper and stainless build
- Flow rate not listed
- Single fixture use only
- Needs a dedicated circuit, amperage not in specs
- Battery listing as power source looks wrong
Performance notes
Output temperature depends on incoming water temperature and how fast water flows through the heater, so a higher flow gives cooler water. The heating element runs only while water moves, which is why standby loss is low. Cold inlet water in winter lowers the outlet temperature.
