This commercial heat pump project in Hungary features 4 units of 50kW commercial heating heat pumps, totalling 200kW, installed for a newly built hotel. The system was designed for space heating and installed by a local HVAC contractor.

Hungary has cold winters, with temperatures in some regions dropping to around -15°C. For a hotel, heating performance directly affects guest comfort and daily operations.
The contractor needed a hotel heating heat pump system that could:
Provide stable heating for a building of approximately 3,000㎡.
Use one flexible heat pump platform across multiple project types — heating, cooling, hot water, or combined applications — to avoid stocking different SKUs for different jobs.
The contractor selected 4 units of 50kW commercial heating heat pump systems, forming a 200kW commercial heat pump installation. All units in this project were configured for heating operation.
Flexible 3-in-1 configuration — the same platform can run heating, cooling, hot water, or combined modes, letting the contractor reuse one model across different commercial projects.
200kW total heating capacity — four 50kW units cover the hotel's heating demand under standard conditions.
Built for local winter conditions — the system carries enough capacity margin for stable operation through Hungary's heating season.
Simpler project planning — one adaptable platform reduces SKU complexity and keeps quoting and after-sales support consistent.
Scalable multi-unit layout — compared to one oversized unit, multiple smaller units give more flexibility in installation and future maintenance.
Built-in redundancy: The system uses four 50kW units in a cascade configuration rather than relying on a single large unit. If one unit needs maintenance or experiences a fault, the remaining three keep running — the hotel's heating system never fully shuts down.
Easier installation logistics: Four 50kW units are far more manageable on-site than one oversized 200kW unit, especially for rooftop installations or space-constrained locations.
Based on the unit's heating performance curve at 55°C water temperature:
Ambient Temperature | Heating Capacity per Unit | COP |
|---|---|---|
-25°C | ~24kW | ~1.5 |
-10°C | ~30kW | ~2.0 |
0°C | ~36kW | ~2.3 |
10°C | ~45kW | ~3.3 |
Even at -15°C, the 4-unit cascade maintains well over 100kW of combined heating output — giving the system enough capacity margin to stay stable throughout Hungary's coldest winter periods, not just under standard test conditions.
Match capacity to building size: For properties around 3,000㎡, a multi-unit cascade setup offers more flexibility than a single oversized unit.
Plan for serviceability: Multiple smaller units provide built-in redundancy and easier on-site maintenance.
Reuse the same platform: The 3-in-1 design means the same model can be redeployed for cooling or hot water projects, reducing the need to manage multiple product lines.
Size for real winter conditions: Check the unit's performance curve at expected ambient temperatures, rather than relying on rated capacity alone, to ensure correct sizing.
Whether you're planning a hotel, apartment building, or any large-scale commercial project — heating, cooling, or hot water — we can help you size the right solution before you commit.
