Heat pumps have now become the first choice for people choosing HVAC systems for their property. You may have heard the term quite often these days, but it may have left you wondering whether it is new technology or what.
The technology is an upgrade from traditional heaters, offering an energy-efficient alternative for modernising your infrastructure. If you’re new to the concept, this blog post breaks down heat pumps to help you decide if one is right for you. Let’s dive in.
What is a Heat Pump Hot Water System?
Traditional heaters consume energy to run heating elements, and one unit of energy equals one unit of heat out. That’s a 1:1 ratio. Overall, it is effective but expensive in these times.
In contrast, a heat pump does not generate heat but transfers it. It is an energy-efficient solution for controlling temperatures inside your property. A heat pump transfers heat from the outside during winter and vice versa in summer.
How Does A Heat Pump Function?
The process is simple, involving only two components: a refrigerant and a compressor. Think the way a refrigeration system works, but only in reverse. Below is the step-by-step process of a heat pump hot water system:
- A fan draws in external air, which then passes over refrigerant-filled evaporator coils.
- The refrigerant converts from liquid to gas after absorbing the heat from the air.
- The gas moves to a compressor, which compresses it tightly into a high-pressure, hot gas, significantly increasing the temperature.
- The gas is transferred to the condenser, where heat exchange converts the refrigerant into liquid form.
- The refrigerant moves through the expansion valve, which converts the liquid into vapour form again, and it finally returns to the evaporator to continue the cycle.
Types of Heat Pumps
Two types of heat pumps are air-to-air and ground-source (or geothermal), both of which are connected to ductwork. Air or ground is a heat source that these pumps collect from outside and transfer for heating purposes.
Air-to-Air Heat Pumps
An air-to-air heat pump is the most common type, using outside air as an energy source to heat or cool your home. It is an energy-efficient system because it transfers heat directly to your room without travelling through a heat distribution system. It also offers simple and quick installation.
Geothermal Heat Pumps
Also known as GHPs, geothermal heat pumps transfer heat from the ground to your home. These high-efficiency pumps heat or cool your spaces; however, their installation is quite expensive compared to air-to-air systems. Geothermal pumps are known to consume 61% less electricity than conventional systems.
Absorption Heat Pumps
Absorption heat pumps are also high-efficiency pumps, powered by thermal energy such as natural gas, solar, or waste heat. They use a thermochemical process with refrigerant-absorbent pairs (e.g., ammonia-water) for heat transfer. AHPs provide high-efficiency heating and are ideal for industrial, commercial, or large residential applications that seek to reduce electricity consumption.
Benefits of Heat Pumps
- Heat pumps consume less electricity than conventional metal tanks to deliver the same capacity. Less electricity means lower energy bills and more sustainable use of a scarce resource.
- These pumps provide comfort throughout the season by heating the house in winter and cooling it in summer. They are also known to provide hot water throughout the year, replacing the need to install electric or gas water heating systems.
- They also reduce carbon footprint by eliminating the use of fossil fuels for energy production, leading to a greener and more sustainable future. Most new pumps on the market also use the energy-efficient and eco-friendly R410A refrigerant.
