Each year, summer temperatures seem to soar higher. Countries that once relied on opening windows to invite a cool breeze are increasingly seeking more effective solutions to maintain comfortable indoor temperatures. While an air conditioner may be the immediate solution that comes to mind, heat pumps should not be overlooked, as they can effectively cool your home as well.

What is a heat pump?
Heat pumps are devices that transfer heat rather than generate it through the combustion of fuel. Typically, they absorb heat from the outside and deliver it indoors for heating purposes, but they can also reverse the process to provide cooling during warmer months. The effectiveness of a heat pump for cooling or heating depends significantly on its connection to different types of emitters within your home.
Different types of heat pumps
Heat pumps come in various types. Air-to-water heat pumps extract energy from the air, whereas ground source heat pumps gather energy from the stable ground temperatures. Both types can be paired with a variety of emitters, such as radiators, underfloor heating, and what are known as fan coil units or heat pump convectors.
Additionally, hybrid heat pumps combine air-to-water technology with gas condensing boilers, selecting the most efficient operation automatically. This system can also integrate with multi-split systems for a full range of heating and cooling solutions.
How does a heat pump cool?
From a technical perspective, cooling with a heat pump involves reversing the heat transfer process. Not all heat pumps are capable of providing cooling, so it is crucial to confirm this feature on the manufacturer’s website or discuss it with your installer. The emitters used also impact functionality—while some emitters, like radiators, are limited to heating, others, like heat pump convectors, excel in both cooling and heating.
What heat pump emitters can be used for cooling?
Heat pumps can work with an array of emitters to maintain year-round comfort. During cold weather, they heat your home, and in warmer weather, they provide cooling through the same emitters.
Fan coil units or Heat Pump Convectors
Fan coil units, or heat pump convectors, consist of a heat exchanger paired with a fan. When set to cool, chilled water flows through the unit. Fans pull warm air over the heat exchanger, cooling it down before it circulates back into the room, effectively lowering indoor temperatures.
Underfloor piping system
Underfloor cooling is another viable option. A heat pump can circulate chilled water through underfloor pipes, absorbing heat from the air that flows over them, promoting a cooler environment. Although this method offers uniform temperature control, care must be taken to prevent condensation on flooring and ensure comfort.
Air conditioners
Some hybrid heat pumps can connect to outdoor units, allowing for an interconnected system that utilizes both air conditioners and traditional heating methods. While air conditioners are well-known for cooling spaces, they also effectively heat interiors.
Is a heat pump an efficient method for cooling your home?
Rising energy costs may make the idea of installing a new heating and cooling system seem daunting. However, heat pumps provide a highly efficient approach. They primarily operate using renewable energy sources. An air-to-water heat pump generally uses about 75% renewable energy, with only 25% sourced from electricity, while ground source pumps are even more efficient, utilizing about 80% renewable energy.
For every 3 to 4 kilowatts of heating produced, only one kilowatt of electricity is consumed, demonstrating a performance efficiency of 300-400% when compared to traditional systems.
Advancements in technology have allowed units like Daikin heat pumps to achieve up to A+++ energy efficiency ratings. Utilizing inverter technology, these pumps adjust their compressor, fan, and water pump speeds as needed, resulting in enhanced energy efficiency.
Top 5 benefits of using a heat pump for your home
1. Heat pumps are energy efficient, which can lower your energy bills.
2. They help reduce your carbon footprint, as most energy used is derived from renewable sources, resulting in less reliance on fossil fuels and significantly lower local emissions.
3. Heat pumps typically have a long lifespan.
4. User-friendly controls allow for easy adjustments; Daikin units can integrate with your home network for remote access via the Onecta app, and some even support voice control through systems like Amazon Alexa or Google Assistant.
5. Heat pumps provide not just cooling, but a complete year-round comfort solution capable of heating, cooling, and delivering hot water.
Daikin offers a wide array of high-performance, energy-efficient heat pumps designed to meet both your preferences and your home’s needs.
