80Degrees Heat Pump

What 80°C Actually Means in Practice

Most heat pumps on the market top out at 55°C or 60°C. That is enough for domestic hot water, underfloor heating and swimming pools — but not enough for a long list of industrial and commercial processes that have traditionally depended on gas or electric boilers.

Raising the outlet temperature to 80°C changes what a heat pump can be used for. It means the unit can directly serve applications that previously had no alternative to combustion:

• Sanitization and CIP cleaning in food, beverage and pharmaceutical plants
• Industrial washing, degreasing and surface treatment lines
• Textile dyeing, drying and finishing processes
• Hotel and hospital hot water systems requiring periodic thermal disinfection
• District heating networks with high supply temperature requirements
• Retrofitting existing radiator systems that were designed for boiler temperatures
• Greenhouse heating and agricultural processing
• Slaughterhouse and dairy hot water for hygiene control

In each of these cases, the 80°C capability is not a small improvement — it is the difference between a heat pump being usable and being ruled out entirely.

Why This Unit Replaces a Boiler, Not Just Supplements One

Direct Retrofit into Existing Systems

Because the outlet temperature reaches 80°C, the heat pump can often be connected directly to existing hot water tanks, radiators, heat exchangers and process pipework without redesigning the entire system. This significantly reduces retrofit cost and downtime.

Lower Operating Cost Than Gas or Electric

Even at high temperature, a heat pump moves heat rather than generating it by combustion or resistance. Compared with electric boilers, the efficiency advantage is substantial; compared with gas boilers, the operating cost advantage grows as fuel prices and carbon costs rise.

No Flue, No Combustion, No Fuel Storage

There is no flame, no exhaust gas, no gas pipeline connection and no fuel tank. This simplifies permitting, improves site safety and removes a major source of emissions.

Lower Carbon Emissions

When powered by grid electricity — and especially by renewable electricity — an 80°C heat pump delivers the same hot water with a fraction of the carbon emissions of a fossil fuel boiler.

Technical Capability

All values are typical and for reference only. Final specifications depend on the confirmed datasheet and project requirements.

Typical System Configurations

How We Approach a High-Temperature Project

1. Load profile review — required temperature, daily hot water or heat demand, peak and average load, operating hours.
2. System temperature analysis — supply and return temperatures, storage strategy, and whether a cascade or buffer solution is needed.
3. Equipment selection — refrigerant, capacity, number of units, control method and integration with existing boilers or tanks.
4. Drawing and layout — system schematic, piping, electrical and control drawings issued for approval.
5. Production and factory testing — performance verified before shipment.
6. Commissioning support — guidance during installation and system start-up.

Frequently Asked Questions

Is 80°C achievable in cold ambient conditions?
80°C outlet temperature is achievable within the unit’s designed operating envelope. Capacity and efficiency will vary with ambient temperature and inlet water temperature. For cold-climate projects, we recommend sharing your site conditions so we can confirm the correct model and configuration.

Can it fully replace our existing boiler?
In many cases yes, and in others the heat pump becomes the primary source with the boiler retained as peak or backup. The right approach depends on your load profile and required temperatures.

Which refrigerant is used?
Depending on the temperature range and model, R290, R134a or R513A may be used. We will recommend the most suitable option based on your application and market requirements.

Does high temperature reduce efficiency?
Efficiency at 80°C is lower than at 55°C — this is inherent to the refrigeration cycle. However, compared with electric boilers and fossil fuel boilers, the efficiency and operating cost advantage remains significant.

Can multiple units be combined for higher capacity?
Yes. Cascade control allows multiple units to operate together as a single system, which also provides redundancy and staged loading.

Do you support OEM / ODM for this product?
Yes. Blueway provides OEM, OBM and ODM services with customized branding, capacity, voltage, refrigerant, control logic and cabinet design.
