Heat pumps are among the most efficient heating and cooling solutions available, but their performance can decline due to several factors. Understanding these issues—and how Nulite’s advanced heat pump technology overcomes them—can help you maximize savings and system longevity.

Key Factors That Reduce Heat Pump Efficiency

1. Extreme Outdoor Temperatures

   •   Problem:

      -  In cold climates (below -10°C/14°F), air-source heat pumps work harder to extract heat, lowering COP (Coefficient of Performance).

      -  In extreme heat (above 40°C/104°F), cooling efficiency drops.

   •   Nulite Solution:

      -  ArcticPro Series with Enhanced Vapor Injection (EVI) maintains COP 2.5+ at -25°C.

      -  Hybrid Cooling Mode optimizes performance in scorching summers.

2. Poor Maintenance

   •   Problem:

      -  Dirty filters, clogged coils, or low refrigerant levels can reduce efficiency by 15–30%.

   •   Nulite Solution:

      -  Self-cleaning filters and smart diagnostics alert users via app when maintenance is needed.

3. Incorrect Sizing

   •   Problem:

      -  An oversized unit short-cycles, wasting energy.

      -  An undersized unit runs constantly, struggling to meet demand.

   •   Nulite Solution:

      -  Free load calculation service ensures perfect sizing for your home.

4. Refrigerant Type & Charge

   •   Problem:

      -  Older refrigerants (like R22) are inefficient and environmentally harmful.

      -  Improper refrigerant levels hurt performance.

   •   Nulite Solution:

      -  R32/R290 refrigerants offer higher efficiency and near-zero GWP.

      -  Precision charging at the factory eliminates guesswork.

5. Defrost Cycles in Winter

   •   Problem:

      -  Frequent defrosting in icy weather consumes extra energy.

   •   Nulite Solution:

      -  Adaptive Defrost Technology minimizes cycles by 30%, saving power.

6. Poor Insulation & Ductwork

   •   Problem:

      -  Heat loss through walls/windows or leaky ducts forces the system to overwork.

   •   Nulite Solution:

      -  Wi-Fi energy monitors identify insulation issues, and our experts provide retrofit advice.
