Air Source Heat Pumps: Common Misconceptions

Air Source Heat Pumps are a more energy efficient alternative to standard boilers for heating your home. As they’re not super common right now, there are many ‘myths’ and misconceptions surrounding the system.

Continue reading this blog to alleviate any concerns you may have about Air Source Heat Pumps.


1. Doesn’t work in older structures; only suitable for new construction

There are several instances of air source heat pumps operating efficiently and saving consumers money in older homes. The system may deliver effective heating as long as the installer develops it based on the property type and the heating needs. There are several aspects that go into an air source heat pump installation, including different types and sizes that must be chosen by a professional installer to meet the demands of the house. Additional steps, such as enhanced insulation, draught proofing, and radiators, may be advised for an older property to keep operating costs low and ensure the customer gets the most out of the system, but this does not rule it out for an older structure. This similar situation would apply to anybody establishing a heating system; if a house is older and not well-insulated, such as with solid walls, the cost of heating it would be greater, and a larger boiler will be needed to meet the heat demand.

Overall, energy-efficient home goods and technologies are now well-understood in a well-established market, allowing us to install air source heat pumps in a wide range of homes.

2. Requires a great deal of insulation

People often assume that in order for a heat pump to operate at all in a house, certain significant insulating measures are required. While it is true that adding additional insulation to the system would make it more efficient and cost less to operate, this does not apply to air source heating any more than it does to conventional boilers. Any heating system will have greater operating expenses if the house has inadequate insolation, but this will not prevent them from functioning. An air source heat pump might be placed in a house with inadequate insulation and an outdated inefficient boiler and yet result in lower energy expenditures. In the case of air source heating, the more insulated the house is, the smaller the heat pump needed, and hence the installation and operating expenses will be reduced.


3. To be eligible for funding, you must be on government assistance.

The good news is that financing for air source heat pumps (and other eco-friendly home renovation projects) is not means tested, so your income is immaterial. Many people believe that substantial awards are too good to be true, and that in order to obtain any money, you must have already received financial advantages, which is not the case.

4. It’s a Noisy Business to Run

Another widespread misunderstanding is that the air source heat pump is loud and disruptive; reports range from keeping you awake at night to having dogs howl at a high frequency! We can guarantee you that this isn’t the case. Older types of air source heat pumps may have made a noise comparable to that of an air conditioner, but today’s models are significantly quieter, with the finest models earning the official “silent mark.”


5. It Doesn’t Work In Temperatures Below 0°C

The air source heat pump can function in temperatures as low as -20°C and is widely used to heat household dwellings in places that experience more harsh weather than Scotland, such as the Netherlands. In freezing conditions, technology can still take heat from the air, and the assumption that it can’t is a prevalent myth.


6. Heat Pumps Aren’t Enough to Keep You Warm

Many people believe that if the radiators aren’t hot to the touch, the system isn’t generating the same amount of heat as a regular boiler. This misunderstanding derives from the fact that heat pumps work differently than conventional systems — let us explain.

When a gas, oil, or LPG boiler initially turns on, it will provide maximum heat output and heat the residence fast, resulting in very hot radiators. A heat pump, on the other hand, is less expensive and more efficient since it can be set to turn on the heating earlier and for longer periods of time to gradually heat the home and maintain the temperature throughout the day. It wouldn’t be worth shutting off the heating to go away for a few hours since the heat pump would have to work harder at a high temperature to fast heat the home upon your return, costing more than if the radiators were kept heated to prevent the house temperature from decreasing. All of the timings can be changed on the thermostats that come with the air source heat pump, so you don’t have to worry about altering anything.

Yes, the radiators may not be as hot as they were with your old system, but this is one of the system’s advantages: it will be less expensive to operate and can be customised to meet your lifestyle. We guarantee you’ll get hot water up to 50 degrees Celsius and a comfortable room temperature of 23 degrees Celsius!


7. It costs a “fortune” to operate in terms of power

Because the air source heat pump system will be running for the most of the day, the widespread belief is that it will cost more to operate. This is clearly not the case. The heat pump will not require excessive kilowatts of power to heat the property or cost you a lot since it uses renewable technology to supply between 2-4x as much energy for the home as it consumes. As previously said, the system only requires a little amount of power to maintain a consistent temperature throughout the day and to keep the radiators warm so that the home’s temperature does not decrease, and you do not need to use the heat pump to bring it back up to temperature on demand. People often query their rising power rates, but they overlook the fact that the expense of the other fuel source has vanished, and the system is saving up to 60% on energy bills when compared to prior bills.


To summarise, air source heat pump technology is remarkable, yet it varies from the classic systems we are most familiar with. As a result, many people still don’t understand how heat pumps function, and there is a lot of disinformation out there that people believe without understanding the truth. We hope that we have clarified some facts and given you a better knowledge of how an air source heat pump system saves energy and money while maintaining your house at a comfortable, consistent temperature throughout the Scottish year.
