The Westinghouse Apolo ET027KA1G is a 27 kW electric tankless water heater built for whole-house use. It delivers up to 6.3 GPM and can run two to three showers plus faucets at once, depending on how cold the incoming water is. It starts heating at just 0.79 GPM, so low-flow fixtures still trigger hot water. The die-cast aluminum chamber resists corrosion, and water-electricity separation is meant to prevent leakage. It suits larger homes with enough electrical service; smaller homes and cold-climate installs may find 27 kW either overkill or not enough in winter.

Owner feedback on the Apolo line is mixed. People like the endless hot water and compact wall mount, but installers and owners report that cold inlet water cuts capacity and that the electrical demands are steep.
The Westinghouse Apolo 27KW is an electric tankless water heater that heats water on demand, so it does not use a storage tank. It is designed as a whole-house solution for larger homes and delivers up to 6.3 GPM.
Depending on inlet water temperature, it supports 2 to 3 showers plus faucets at the same time. It starts heating at a flow of only 0.79 GPM, which suits areas with lower water flow.
The heating chamber is die-cast aluminum with high corrosion resistance. Water-electricity separation technology prevents electric leakage. The unit is wall-mounted and hardwired, and installation by a licensed electrician is recommended.
