Hydro Solar air-to-water heat pumps: the heat comes in through water
A Hydro Solar does not blow warm air: it heats the water in a hydronic system, and that water does the rest. Two layouts, one real question: monobloc or split. We help you choose, and we install across Montreal, Laval, Longueuil, the South Shore and the North Shore.
A brand of Aqua Solanor Inc., Lachine, QuebecWhat goes through the wall?
Split: refrigerant goes through the wall; the water stays inside. The two units: 5 m apart at most.

The result: the right Hydro Solar layout for your water-based system, chosen with you and installed by AirGreen.
01 · Monobloc or split
Same job, two ways through the wall.
Either way, the compressor stays outside and the heat ends up in your water. What changes is where the heat exchange happens, and so what runs through the wall: water, or refrigerant.
Monobloc
Split
Outside
The whole unit: compressor, fan and refrigerant-to-water heat exchanger.
Panasonic DC inverter EVI compressor, fan, 4-way valve.
Inside
No unit: water goes straight to the tank or the emitters.
A wall-mounted unit: refrigerant-to-water heat exchanger, water flow switch, CAREL controller.
What goes through the wall
Water (supply and return).
Refrigerant, in copper lines.
Water connections
On the outdoor unit: 1 in. FNPT, 1 ¼ in. on the largest size.
On the indoor unit: 1 in. NPT.
Distance between units
Not applicable: a single unit.
5 m maximum, horizontal and vertical added together; 5 m of pre-insulated lines supplied.
Watch for
The water loop leaves the house: protecting it from freezing is part of the design.
You need wall space near the point where the lines come in.

02 · The 5-metre test
The split has one simple rule: 5 m, not one more.
Hydro Solar supplies 5 m of pre-insulated copper lines and sets the maximum distance between the two units at 5 m, horizontal and vertical added together. Measure your run.
Your run between the two units
0 m5 m: limit24 m
4 m
A split works.
Your run fits within the 5 m supplied. Now find wall space for the indoor unit.

03 · What the water can do
Once the water is hot (or cold), what it is used for.
Pick a use: on the left, what the Hydro Solar manuals say; on the right, what to plan for in your home.
Hydronic heating
Hot water flows through your emitters.
What Hydro Solar says
- Hydronic space heating is one of the uses the manufacturer lists.
- An outdoor reset curve adjusts the water temperature to the outdoor temperature.
- Terminals are provided for electric backup heat.
What to plan for
- Water emitters: heated floor, fan coils or others.
- A buffer tank, as in the manufacturer’s diagrams.
- Wiring the electric backup.

08 · Frequently asked questions
What people ask us about Hydro Solar air-to-water units.
It takes heat from the outdoor air and transfers it to water. That water then flows through a hydronic system: heated floor, fan coils, tank. It can also make cold water for summer cooling.
