Instant Tankless Electric Water Heater, 3500W With Temperature Knob
Details
No tank taking up floor space, no waiting for a reservoir to heat back up — the Kirrea mounts flat against a wall about the size of a carry-on suitcase and heats water the instant it flows through, right at the point you need it. Set your temperature on the knob, and hot water reaches your tap in roughly three seconds thanks to the integrated thermostat working behind a stainless steel shell.
Because it only heats water on demand, you're not paying to keep a tank hot around the clock — and there's no standing water to pick up rust or scale.
Features
- 3500W on-demand heating — an integrated thermostat brings hot water to your tap in about 3 seconds, with a knob to dial in your preferred temperature.
- Runs efficiently — rated up to 99% energy efficient, and heating only on demand can cut your water-heating energy use by up to 40% compared with keeping a tank hot all day.
- Compact wall mount — about the size of a carry-on suitcase, it fits in a closet, on an exterior wall, or tucked under a sink, freeing up floor space a tank system would take.
Where to install it
Use it to serve a single point — a shower, a bathroom sink, a kitchen tap — or size your setup to cover a whole home. Its compact, wall-mount build keeps installation costs down compared with a full tank system, and because water only passes through when you need it, you get a fresh, clean supply without the rust or scale buildup that can develop inside a storage tank over time.
Built-in safety
An LCD display shows your set temperature at a glance. The unit carries an IPX4 waterproof rating, isolates the water path from the electrical components, includes dry-heating protection, and shuts itself off automatically if it detects a leak or runs over-temperature.

Frequently asked questions
How fast does the water heat up?
About 3 seconds from when it starts flowing, thanks to the built-in thermostat — there's no tank to wait on.
Where can I install it?
Anywhere convenient and close to where you need hot water — a closet, an exterior wall, under a sink — since it's compact and wall-mounted rather than tied to one utility room.
Does it work for a whole house or just one tap?
Both are possible: run it as a single-point heater for one shower or sink, or size a setup to cover your whole home's hot water needs.
