01
OUTDOOR UNIT
The heat pump, with an EVI scroll compressor. It pulls heat from outdoor air down to −30°C.
Heating, cooling and hot water from one machine
It does the job of an air conditioner, a heater and a hot water tank. It costs less to install than those three, and less to run every year.
Efficiency
Up to 5.46 COP
In summer it makes hot water out of the heat an air conditioner would throw outside.
Cold climate
Down to −30 °C
Full heating output at −30 °C. A standard split starts losing capacity below −15 °C.
Storage
No tank
The same hot water as a 50 gallon tank, in a quarter of the space.
Cost
C$1,500 less
Per apartment on day one, before any energy saving. About C$150,000 across a 100-unit building.
NEWS
What we've built so far
Two prototypes and a patent filing. The first was tested outdoors in 2025, and the second is being assembled now.
Summer 2025
The first prototype
An outdoor test rig, built to measure how much waste heat we could move into water.

The second prototype
Our own enclosures, wiring and control board, built for the product rather than for testing.

WHAT YOU GET
What the system does
PRICING
One price, installed
C$7,000 per apartment, installed. That's about C$1,500 less than a separate air conditioner, heater and hot water tank, and about C$342 a year less to run.
THE APP
Check on it from your phone
Room temperature, hot water and energy use, in one app you can check from anywhere.
See the appCONTROL
It runs itself
Minute by minute, it splits power between heating, cooling and the battery. It only needs one thermostat, so there are no extra sensors in the walls to fail.
EFFICIENCY
It reuses the heat instead of dumping it
In summer, heat pulled out of the apartment goes into the hot water rather than outside. In winter, the same hardware runs in reverse to heat the rooms.
