- Is 27 kW enough for a whole house?
- It can supply a whole house in mild climates, but output depends on incoming water temperature. In cold regions the achievable flow drops, so size it against your coldest inlet water and peak demand.
- What electrical setup does it need?
- A 27 kW unit typically needs a 240 V supply split across multiple high-amperage breakers and heavy-gauge wiring. Most homes need a panel upgrade and a licensed electrician.
- Does it work with hard water?
- Hard water can cause scale buildup inside the heating chamber. A water softener or regular descaling helps protect performance and lifespan.
- How is it different from a tank heater?
- It heats water only as it flows, so there is no tank to keep warm and no stored supply. You get continuous hot water but no reserve during a sudden high demand.
- Can I install it myself?
- Most buyers should not. The high current, dedicated circuits and plumbing connections make professional installation the safer and often required choice.
