Heat Pump Technology That Breaks Its Own Category's Rules
Off Grid Energy delivers industrial air-to-water heat pumps built on patented PSHI™ technology from Norwegian manufacturer Neotemp — cutting energy costs by up to 75%, engineered specifically for Norway's climate.
Why This Isn't A Typical Heat Pump
Patented PSHI™ Technology
Most heat pumps lose energy through a plate heat exchanger. PSHI™ eliminates it entirely, transferring energy directly from refrigerant gas to the water tank — capturing 100% of the heat the system produces instead of losing a share of it in conversion.
Up To 75% Lower Energy Costs
With a SCOP of 4–5 — maintained even in cold climates — the system delivers far more heat energy per kWh consumed than conventional alternatives, with a typical payback period of just 3–4 years.
Hot Water To 80°C
PSHI™ produces domestic hot water above 80°C using only the heat pump's own energy production — no electric backup elements. That's hot enough to eliminate the need for a legionella control program entirely.
Built For Norwegian Buildings, In Norwegian Winters
Off Grid Energy's industrial heat pumps are designed for apartment buildings, commercial properties, and industrial facilities across Norway — both new builds and retrofits. Each installation is modular and scalable, with capacity up to 3,600 m² per module, so the system is sized to the building rather than forcing the building to fit a fixed product. The technology behind it was developed north of the Arctic Circle, built from the outset to perform in exactly the conditions it's installed in.
Why Facility Owners Choose This System
Defrosting, Solved
Conventional heat pumps spend up to 13% of their total runtime in defrost cycles, drawing on electric backup heat to compensate. PSHI™ defrosts 8–15 times faster — as little as 45 seconds per cycle — keeping performance and energy tank levels virtually untouched.
Simultaneous Heating
Most systems have to choose: divert full output to hot water and let space heating draw on backup electric elements, or the reverse. PSHI™ supplies both functions at once, without the extra electricity draw.
Plug & Play Installation
Delivered as a complete, modular system — refrigeration, plumbing, and electrical work completed and certified before it reaches site. Installation time is measured in days, not weeks.
Performance Logging
Every system ships with performance logging as standard, so energy savings are documented and visible from day one — not just promised.

Stats
Performance logging
Every installation includes built-in performance logging as standard — energy production and efficiency are tracked and visible, not just estimated at time of sale.
Sound & compliance
Outdoor-installed energy units with natural refrigerants virtually eliminate noise pollution, comfortably meeting regulatory requirements such as NS 8175.
Frequently Asked Questions
-
Standard systems use a plate heat exchanger to transfer heat from refrigerant gas to water, which wastes energy in the process. PSHI™ removes that step entirely, transferring heat directly into the energy tank — capturing energy other systems simply lose.
-
Actual savings depend on your current heating system and building size, but the underlying efficiency gain — SCOP 4–5 sustained through Norwegian winters, plus dramatically faster defrosting — is what drives the number. A site assessment gives you a figure specific to your building.
-
Both. The modular Plug & Play design is built for retrofits as much as new construction — outdoor installation and completed, certified plumbing and electrical work keep disruption to a minimum either way.
-
No. PSHI™ produces domestic hot water above 80°C using only the heat pump's own energy production, which eliminates the temperature threshold legionella programs exist to maintain.
-
Very quiet. The natural refrigerant and outdoor-installed design virtually eliminate noise pollution, comfortably meeting regulatory sound requirements such as NS 8175.
-
The system scales modularly up to 3,600 m² of capacity per module, suited to apartment buildings, commercial properties, and industrial facilities alike. Larger sites simply combine modules.
-
The Plug & Play systems use a propane-based refrigerant with a GWP of just 2 — putting it on par with CO₂-based systems for sustainability, while avoiding the higher-GWP refrigerants common in older heat pump systems.
-
The heat pumps are manufactured by Neotemp, a Norwegian company that developed and patented PSHI™ technology specifically for Norwegian climate conditions. Off Grid Energy delivers, installs, and supports the system locally.
