Air source heat pumps

Heat pumps have recently received a lot of media attention due to the British government’s plans to phase out new gas boiler installations by 2025. Despite this attention, little is known by the general public about how this technology actually functions.

Air source heat pumps function by drawing in the small amounts of heat that are present in the air, even at lower temperatures outside a property.

In air-to-water heat pumps, the heat from this air is transferred to a fluid by a heat exchanger. Once the heat is transferred to the fluid, the fluid is condensed to increase the temperature (as the pressure of a substance increases, so does its temperature). This condensed fluid then transfers its heat to the water via another heat exchanger. The hot water is then used throughout the property for tap outlets and to fuel heating appliances such as radiators and underfloor heating systems.

Air-to-air heat pumps work slightly differently, as they don’t transfer the heat from outside to a fluid, but instead keep it in the form of air. This air then follows a similar process of being condensed to increase the temperature, which is then transferred throughout the property via ducting to provide warm air heating. This is a dry system, as opposed to the wet system used by air-to-water heat pumps. Often, this method is favoured in commercial settings such as office buildings, as they can also provide air conditioning.

Ground source heat pumps

Ground source heat pumps work much the same as air source heat pumps, with the main difference being how they gather heat from the outside environment.

Ground source heat pumps function by gathering the small amounts of stored heat in the ground outside using pipes filled with water and antifreeze (often called brine). The same process as an air source heat pump is then followed by transferring this heat to a fluid, condensing the fluid to increase the temperature, and then transferring this heat again to the hot water needed for the property’s system.

Ground source heat pumps are usually in the same format as air-to-water heat pumps, often not having the same capabilities to provide air conditioning or warm air heating. However, as this technology receives more and more attention, it is constantly being developed, and there are now ground source heat pump models with the same functionality as air-to-air heat pumps.

If you are considering having an air source or ground source heat pump installed, check out the ‘Boiler Upgrade Scheme,’ a governmental scheme that offers grants to upgrade your existing boiler system to a more environmentally conscious option such as air source or ground source heat pumps.

Heat pump FAQs

Your questions about heat pumps answered

The cost of installing a heat pump depends on various factors, such as the size of the unit, the complexity of installation, the location, and more. Generally, the cost of installing a heat pump can range from £3,000 to £10,000 or more. For a larger property, the cost may be higher, but for a smaller property it would be less. It’s important to consider factors such as energy efficiency, maintenance costs, and the area in which you live when determining if a heat pump is the right choice for you. Often the energy efficiency and energy saving benefits make installing a heat pump beneficial to property owners. Additionally, you may be eligible for government incentives or rebates that can help offset the cost of installation like the ‘Boiler Upgrade Scheme‘ . We always recommend consulting with one of our licensed HVAC contractors to get a clear estimate for your specific situation.

The lifespan of a heat pump varies depending on the quality of the unit, the amount of usage, and the level of maintenance. Generally, a well maintained heat pump can last for 10-15 years or more. However, some high quality models have a lifespan of up to 20 years. Factors that can affect the lifespan of a heat pump include the environment it operates in, the frequency of use, and the level of maintenance. To maximise the lifespan of a heat pump, it is recommended to have it serviced annually by a professional technician and ensure that it is properly installed and sized for your property. Regularly changing air filters, ensuring proper air flow, and addressing any issues promptly can also help extend the life of your heat pump.

The cost of running a heat pump has no simple answer and is dependant on the heat demand of your property. Heat pumps run on electricity, so to figure out the average cost you will need the price of electricity at the time, your property’s average heat demand and the efficiency of the heat pump in question. For example, say a unit of electricity is £0.3 per kWh, the average heat demand annually for a property in the UK is 12,000 kWh and a heat pump will produce 3 kWh of heat for every 1kWh of electricity. You would then have to divide the average heat demand by the kWH of heat produced by a heat pump e.g. 12,000kWh / 3kWh = 4000kWh. You would then multiply the cost of electricity per kWh by the result of the previous sum e.g. 4000kWh x 0.3 = 1200. Making the annual cost of running your heat pump £1200 per annum. When you compare this to the cost of a gas boiler which is estimated to be between £600 and £800 per annum depending on the boiler used, then you can see it is actually quite expensive to run a heat pump.

Whether a heat pump can heat and provide hot water for a whole house year round depends on many factors, such as the size of your property, the heat demand of your property, and the weather around the location of your property. Quite often, a heat pump will need to be accompanied by a back-up system (such as a combi boiler or water heater) if the location of the property experiences fairly cold weather or if the property has a sizeable demand for heating and hot water. This circumstance is prevalent in the UK due to the indecisive and fairly cold weather, leaving many homes with heat pumps needing a hybrid system to boost the output of their system. Although heat pump technology is quickly evolving, so hopefully soon a heat pump will have no problem providing heating and hot water for an entire property, regardless of the demand and weather conditions.

Heat pumps can make some noise, but it is typically not excessive. The outdoor unit of a heat pump will make some noise while it is running, similar to an air conditioner or a refrigerator. However, most modern heat pumps are designed to be relatively quiet, with sound levels comparable to a conversation or a dishwasher. Indoor units may also make some noise, such as the sound of air flowing through ducts or the fan motor. Some people may be more sensitive to noise than others, but overall heat pumps are not generally considered to be noisy appliances. If you have concerns about the noise level of a heat pump, it is a good idea to talk to one of our professional heat pump engineers who can recommend models that are specifically designed to minimise noise.

Whether or not you will need new radiators and insulation when installing a heat pump depends on the condition and effectiveness of your current system. Heat pumps work differently from traditional heating systems, so it is possible that your radiators may not work as efficiently once using heat pumps. However, many heat pumps are now designed to work with existing radiator systems without a problem so it is largely dependant on the heat pump chosen for your property.

Insulation, on the other hand, plays a critical role in how well a heat pump operates. A properly insulated home can reduce heat loss, which makes your heat pump more efficient. In most cases, you will not need to install new insulation when you switch to a heat pump if your insulation is already of a decent quality. However, if your home has poor insulation, it is highly recommended to improve it as it will reduce energy costs and increase your home’s value. One of our qualified heat pump technician can assess your home and recommend any upgrades to ensure optimal heat pump performance.
