Find out about the different types of heat pumps, how they work and why they could help to tackle climate change.
How a heat pump works
A heat pump uses the same technology as an air conditioner, which cools your home using a refrigerant. The only major difference between an air-conditioner and a heat pump is that a heat pump has a reversing valve, which allows it to also heat your home.
In heating mode, a heat pump works like an air conditioner in reverse; instead of keeping your home cool, it uses the refrigerant to warm your home.
Here&#;s a step-by-step process of how heat pumps work:
Heat could be sourced from the air outside or warmth from the ground. This is blown or pumped over the heat exchange surface of the exterior part of the heat pump.
This heat is warm enough to cause the refrigerant liquid in the heat pump to evaporate and turn into a gas.
This gas is then moved through a compressor, which increases the pressure, causing its temperature to rise.
The gas (now heated) is passed over the internal heat exchange surface. This heat can then be either blown around the home's interior or transferred into a central heating or hot water system.
As the heat is transferred into the home, the gas falls in temperature, causing it to return to a liquid state.
The cycle of reverse refrigeration repeats until your home reaches the required temperature setting on your thermostat.
If heat pumps obtain their heat from outside, how do they provide heat on a cold day?
Even when it&#;s very cold outside, some heat energy still exists. Heat pumps are effective at taking this heat energy from the ground or air around a building and using it to provide heat for your home or business.
For heat pumps to work at their best, it&#;s also important that the building has good energy efficiency installed, such as effective insulation.
What different types of heat pumps are there?
There are different types of heat pumps: air-source and ground-source.
Heat pumps can also be paired with fossil fuel gas furnaces; these systems are often referred to as hybrid heat pumps.
How does an air-source heat pump work?
Air-to-water heat pumps take heat from the outside air and feed it into your wet central heating system (similar to existing gas central heating). As the heat produced is cooler than that from a conventional furnace or boiler, you may need to install larger radiators or underfloor heating in your home to make the most of it. Air-to-water heat pumps may be best suited to new-build properties or those that are energy efficient.
Air-to-air heat pumps take heat from the outside air and feed it into your home through fans. This type of system can be used for heating but can&#;t produce hot water.

How does a hybrid heat pump work?
Why are heat pumps important in helping reach net zero?
Around 40% of global emissions come from buildings and most of these result from the ways we heat our homes and businesses.
To reach net zero carbon emissions and tackle climate change, we need to switch from heating that relies on high-carbon fuels to cleaner, low- or zero-carbon alternatives.
Heat pumps will help to achieve this for two main reasons:
Heat pump systems are designed to extract a greater amount of heat energy from the surrounding environment than the energy they consume to create heat. They can produce two to three times more heat output than they consume in electricity input.
As more and more electricity is generated from renewable energy sources like solar or wind power, the electricity used to power heat pumps is itself becoming cleaner.

If you're aiming to steer your business towards a more sustainable future, commercial air source heat pumps should definitely catch your attention.
But how do they stack up against traditional gas boilers in terms of effectiveness and efficiency? And what about installation and operational costs?
In this discussion, we'll delve into all aspects of commercial air source heat pumps. This will help you assess whether transitioning to this eco-friendly heating system is a worthwhile investment. Hint: it certainly is!
WHAT ARE COMMERCIAL AIR SOURCE HEAT PUMPS?
Commercial air source heat pumps use electricity to heat or cool buildings. During winter, they extract warmth from outdoor air, even in temperatures as low as -15°C, and transfer it indoors via a compressor or heat exchanger. This method of heating buildings and hot water is comparable to a conventional boiler.
In summer, these pumps operate similarly to air conditioning units, moving heat from inside a building to the outdoors to cool it down.
Crucially, air source heat pumps provide heating and cooling without relying on fossil fuels, making them a sustainable alternative to traditional gas boilers.
While these eco-friendly heating systems are increasingly popular in residential settings, government initiatives like the Boiler Upgrade Scheme help offset initial costs, making them appealing for businesses as well.
Commercial air source heat pumps function similarly to residential models but are tailored to meet the specific challenges of heating and cooling larger commercial buildings.
ARE HEAT PUMPS SUITABLE FOR COMMERCIAL BUILDINGS?
Heat pumps offer an effective alternative to traditional boilers for heating and cooling various types of commercial buildings, ranging from offices to swimming pools, supermarkets, and showrooms.
Not only do they significantly reduce a business' carbon footprint, but they are also remarkably more efficient than traditional fossil fuel-powered boilers, often performing three to four times better. This efficiency allows businesses to adopt greener heating systems without compromising on heating and cooling capabilities.
Here are the key benefits of making the switch:
1. Increased Efficiency: Heat pumps generate more heat than the electricity they consume. Air source heat pumps, for instance, are three to four times more efficient than gas boilers.
2. Reduced Energy Bills: Transitioning from an old, inefficient fossil fuel-powered boiler to a modern air source heat pump can lead to substantial savings on energy bills.
3. Sustainability: By relying on green energy for heating and cooling, businesses can significantly reduce their carbon footprint.
4. ESG Benefits: Embracing a greener heating system demonstrates a commitment to environmental, social, and governance (ESG) principles, showcasing a community-minded approach and concern for the impact on surroundings.
Switching to heat pumps not only enhances operational efficiency but also aligns with sustainability goals, making it a strategic choice for businesses looking to lead by example in environmental stewardship.
WHAT'S THE UPFRONT COST OF A COMMERCIAL AIR SOURCE HEAT PUMP?
The upfront cost of installing a commercial heat pump can vary significantly based on the specific requirements of each business. For example, heating an office space differs greatly from heating an indoor swimming pool.

Several key factors influence the total cost, including:
- Size of the business premises
- Level of insulation in the building
- System capacity and efficiency
- Desired room temperature settings
- Requirements for noise reduction features
- Type of system (monobloc or split system, which may involve units placed solely outside or both inside and outside the building)
WHAT ARE THE AVERAGE HEAT PUMP RUNNING COSTS?
Currently, the running costs of heat pumps are comparable to those of modern gas-powered boilers. However, heat pumps are significantly more efficient, operating at about three to four times the efficiency of boilers.
While the most efficient boilers can achieve up to 98% efficiency, air source heat pumps can reach efficiencies of around 300%. This seemingly high efficiency is because heat pumps transfer heat rather than generate it.
So, why aren't heat pumps much cheaper to run? The main factor is that electricity, which powers heat pumps, is currently more expensive than gas. As the UK continues to transition to renewable energy sources, the cost of running heat pumps is expected to decrease significantly, making them a more economical choice.
HOW MUCH COULD YOU SAVE WITH A HEAT PUMP FOR YOUR BUSINESS?
The savings from switching to a heat pump depend on your current heating system. Replacing an old, inefficient fossil-fuel-powered boiler with a new air source heat pump can lead to substantial reductions in heating bills.
Furthermore, if you supplement your heat pump with renewable energy sources like solar panels, your savings can be even greater. By generating your own electricity, you reduce dependency on the National Grid and lower operational costs.
Moreover, electrifying heat with a heat pump enables flexibility in energy usage, leveraging cheaper electricity rates during off-peak times. This grid flexibility is crucial for optimizing energy costs and aligning with future energy trends.
Oversizing your thermal storage capacity enhances these benefits, potentially cutting utility costs by up to 20%.
IS MY BUILDING RIGHT FOR A COMMERCIAL AIR SOURCE HEAT PUMP?
Heat pumps are generally a suitable heating option for most businesses, being the preferred choice for both residential and commercial buildings due to their affordability and ease of installation.
However, the suitability of an air source heat pump installation can vary depending on the specifics of your commercial building. Here are some considerations to determine if an air source heat pump is viable for your business:
1. Building Age: Older buildings can accommodate heat pumps, but may require additional adjustments for optimal performance.
2. Insulation Level: Adequate building insulation enhances heat pump efficiency. Consider upgrading insulation before installation.
3. Existing Heating System: Your air source heat pump can often utilize existing pipework designed for gas boilers, potentially reducing installation complexity.
4. Radiators: Heat pumps operate at lower temperatures than boilers, necessitating larger radiators for comparable heat output.
5. Outdoor Space: An air source heat pump requires outdoor installation space, such as a garden, balcony, or mounted on an outdoor wall.
Considering these factors will help determine if an air source heat pump is a practical and effective heating solution for your commercial premises.
WHAT ARE THE ALTERNATIVES TO A COMMERCIAL AIR SOURCE HEAT PUMP?
While air source heat pumps are a popular choice for green heating, there are other options available to businesses, such as ground source heat pumps and water source heat pumps.
Ground Source Heat Pumps
A ground source heat pump extracts warmth from the ground rather than the air. It is installed underground, making it visually discreet and quieter than an air source heat pump. Ground source heat pumps are highly efficient and have a longer lifespan compared to air source systems. However, they typically involve higher upfront costs and more disruptive installation.
Water Source Heat Pumps
Water source heat pumps operate similarly to ground source heat pumps but extract heat from water sources like ponds, rivers, or lakes instead of the ground. They are even more efficient than both air source and ground source heat pumps. Additionally, installation is often more cost-effective and less invasive since it doesn't require extensive digging or drilling.
These alternative heat pump systems offer businesses flexibility in choosing a sustainable heating solution that best fits their specific needs and operational requirements.
