What Are Heat Pump Hot Water Systems?
Heat pump hot water systems are water heaters that transport heat to another place instead of generating heat directly on the spot using electricity. This means they are two to three times more efficient than traditional electric resistance water heaters. Simply put, heat pump systems rely on thermodynamics to transfer existing heat from one source to another, providing a more environmentally friendly way to heat water.
How a Heat Pump Hot Water System Works
A heat pump hot water system operates on the same principles as a refrigerator but in reverse. It extracts heat from the surrounding air or ground, intensifies it using a compressor, and transfers it into a water storage tank.
Here is a complete breakdown of the process:
- Evaporation: A refrigerant liquid fluid within the heat pump evaporates as it absorbs heat from the ambient air, water source, or ground. This low-pressure vapour passes through the evaporator coil.
- Compression: The vapour is compressed using a compressor in the heat pump, increasing the overall temperature and pressure. This step only requires a small amount of electricity to function properly.
- Condensation: The high-pressure, high-temperature vapour releases its heat to the water in the storage tank through a condenser coil, causing the refrigerant to condense back into a liquid state.
- Expansion: The pressure of the refrigerant is reduced as it passes through an expansion valve, returning it to a low-pressure state and preparing it for the evaporation cycle to begin again.
Comparing Heat Pumps With Traditional Water Heating Methods
In contrast to conventional electric or gas water heaters, heat pump hot water systems offer various advantages:
- Energy efficiency: Heat pumps are more energy-efficient since they move heat rather than generate it on the spot. This process can save up to 90% of energy expenses compared to electric resistance heaters that often waste energy production.
- Reduced operating costs: Heat pumps being more efficient can translate into lower operating costs over time. While the initial installation cost might be higher, the long-term savings are substantial and well worth a portion of your budget.
- Environmental friendliness: Hot water heat pumps have a lower carbon footprint because they utilise heat from the air or ground, which are both renewable resources. They produce fewer greenhouse gas emissions compared to fossil fuel-based systems.
- Consistent performance: A heat pump system provides a consistent supply of hot water regardless of external weather conditions. Unlike solar water heaters, they don’t depend solely on sunlight for operation.
Types of Heat Pump Systems
There are various types of heat pump systems to consider, and each comes with its own features and benefits:
Air Source Heat Pumps
Air source heat pumps are designed to extract heat from the ambient air, even in cold weather, and use that heat to warm the indoors. The vaporised refrigerant releases heat indoors while it condenses back into a liquid state.
They are commonly used in small commercial settings since they can only heat up a limited space.
Ground Source Heat Pumps (Geothermal)
Ground source heat pumps are geothermal systems that harness heat from the ground through buried pipes containing a heat-transfer fluid. These systems leverage the stable temperature of the ground or groundwater to provide energy-efficient heating and cooling solutions.
These hot water heat pumps can be more expensive to install, but they’re one of the best systems for reducing your energy bills.
Water Source Heat Pumps
Water source heat pumps extract heat from a water source such as a lake, river, or well. In heating mode, the heat pump maintains a more stable temperature than air when using a water-to-refrigerant heat exchanger. These systems are highly efficient but require consistent access to a water body.
Hybrid Heat Pumps
A hybrid system combines a heat pump with a traditional electric element. It switches between the two based on energy prices, demand, and weather conditions. The heat pump mode uses heat from surrounding air or ground while the electric mode has an electric heating element that provides a continuous supply of hot water.
