Heat pump FAQs

Key Factors Determining Heat Pump Running Costs The operating cost of a heat pump depends on 4 core variables: Efficiency (COP/HSPF2): Coefficient of Performance (COP) measures heat output per unit of electricity input (typical range: 2.5–5.0) . Energy Consumption: Power rating (kW) and operating hours (varies by climate and building size). Electricity Rates: Regional differences (commercial [...]

Yes, heat pumps are highly effective for heating domestic hot water (DHW) — a versatile function that makes them a one-stop solution for both space heating and water heating needs. This dual capability not only simplifies home energy systems but also delivers significant cost and efficiency benefits compared to traditional water heaters (e.g., electric resistance, [...]

Kolant EVI heat pump units can work properly in the cold weather of Scandinavia. Their core technology is optimized specifically for low-temperature environments, making them fully compatible with the local climate. EVI (Enhanced Vapor Injection) technology significantly improves low-temperature heating performance through quasi-two-stage compression and vapor injection enthalpy increase design: in the region’s typical winters [...]

Kolant EVI (Enhanced Vapor Injection) heat pumps realize outstanding low-temperature performance via optimized refrigeration cycle and special structural upgrades. First, it adopts an EVI enhanced vapor injection compressor with an economizer. Different from ordinary single-stage compression, it injects intermediate low-temperature refrigerant vapor into the compressor’s compression chamber. This achieves a quasi two-stage compression effect, effectively [...]
