How Our Split Heat Pumps Work
The Rinnai Enviroflo S utilizes advanced heat pump technology to heat water using energy from the air, making it a highly efficient, low-emission solution for everyday hot water use. The process involves:
- Air is Drawn In: A quiet, efficient DC fan draws ambient air across the evaporator coil in the external compressor unit. The system can extract usable heat from the air even in cool conditions.
- Heat is Captured: The evaporator transfers thermal energy from the air into the refrigerant, which absorbs heat and turns into a warm gas.
- Compressor Boosts the Heat: The refrigerant gas is compressed, rapidly increasing its temperature. This is the core of the heating cycle, converting low-level heat into usable energy.
- Transfers Heat to the Water: The hot refrigerant flows through a double-wall heat exchanger inside the heat pump, safely transferring its heat to the water.
R290 Refrigerant
The R290 refrigerant is sustainable and non-toxic, possessing zero Ozone Depletion Potential (ODP) and a GWP of just 0.02. This is significantly lower (50 times less) than CO2 and outperforms other heat pumps that typically use refrigerants with higher GWP values, such as R32 (GWP=675), R134A (GWP=1430), and R410A (GWP=2087).
