Our take on the Eccotemp SHiE-27 Electric Tankless Water Heater

The Eccotemp SHiE-27 is a 240V electric tankless water heater built for whole-home or heavy point-of-use demand. It heats water on demand, so there is no tank to run out and no standby heat loss. It needs a large dedicated electrical circuit and professional installation, which puts it in the same class as other high-output electric tankless units. Owners like the endless hot water and compact wall mount; the main trade-offs are electrical capacity and limited output in cold climates.

Questions and answers

How much electrical service does the SHiE-27 need?
It runs on 240V and draws high current, so it needs one or more large dedicated breakers and correctly sized wiring. A licensed electrician should confirm your panel can carry it.
Is it good for a whole house?
It can serve a whole home when sized for your climate and fixtures. In cold regions the incoming water temperature lowers output, so check the flow rate you need.
Does it work with hard water?
It will work, but scale can build on the elements. A water softener or regular descaling helps protect performance and element life.
Can I install it myself?
Most owners hire a licensed electrician and plumber. The electrical circuit and plumbing connections are not typical DIY work.
How is it different from a tank heater?
It heats on demand with no storage tank, so it never runs out and takes less wall space. The trade-off is a larger electrical requirement and no hot water during a power outage.
