The present disclosure provides a device and a method for detecting leak in a tankless water heater. According to the present disclosure, a leak detection device is disposed on a base of the tankless water heater. The leak detection device includes a leak sensor and at least one absorption arm extending from the leak sensor. The absorption arm wicks water and transports the wicked water towards the leak sensor. The leak sensor generates a signal indicative of leakage in the tankless water heater, in response to sensing wetness.

Leak detection in tankless water heater

A heat pump water heater has a tank, a heat source, and a heat pump system. The heat pump system has a refrigerant path, at least a portion of which is in thermal communication with the water tank volume so that heat transfers from refrigerant to the water tank volume. A fan causes air to flow through a housing, and another portion of the refrigerant path includes an evaporator in the housing. The fan is within the housing and may further be within a second housing. The first housing may comprise a baffle to direct air flow. The fan may be a variable speed fan in communication with a controller, so that the controller controls the fan speed depending on a temperature of the refrigerant.
