01
OUTDOOR UNIT
The single-compressor heat pump. Pulls heat from outdoor air down to −30°C using EVI scroll compression.
Heating, cooling and hot water from one machine
It does the work of an air conditioner, a heater and a hot water tank. Cheaper to put in than the three of them, and cheaper to run every year after.
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 have built so far
Two prototypes and a patent filing. The first prototype was tested outdoors in 2025. 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.

INDUSTRY COVERAGE
What is happening in the industry
Three things are changing at once. Apartment buildings are moving to electric heating, refrigerant rules are tightening, and controls are getting better. Here are recent articles on each.

WHAT YOU GET
What the system does
PRICING
One price, installed
C$7,000 per apartment, installed. That is about C$1,500 less than buying an air conditioner, a heater and a hot water tank separately, and about C$342 a year less to run.
THE APP
It is all at your fingertips
Room temperature, hot water and energy use, all in one app. Set it once and it holds, or change it from anywhere you happen to be.
CONTROL
It manages itself
It decides how to split power between heating, cooling and the battery, minute by minute. One thermostat is all it needs, so there are no extra sensors in the wall to fail.
EFFICIENCY
It reuses the heat instead of dumping it
The heat taken out of an apartment in summer goes into the hot water instead of out the back of the building. In winter the same hardware runs in reverse to heat the rooms.
