Heat pumps are energy efficient alternatives to AC and ovens, however, even these systems have their own disadvantages. Heat pumps have a high initial cost, some types have a complicated installation process, and many units become less efficient as temperatures drop. A heat pump is a versatile system that provides both warm and cold air to your home. It is often installed outdoors and uses geothermal heat or thermal energy from the surrounding air to operate.
Heat pumps are an excellent alternative to ovens, depending on the climate in which you live. To help you choose a new heating system, we have compiled an extensive list of the benefits and drawbacks of installing a heat pump system in your home. When energy bills start to rise, most of us wonder if there is an alternative. Considering renewable energy as a source of heat has become the necessary option for homeowners, not least because we know that gas and electricity from fossil fuels will soon be a thing of the past.
The transition to green technologies, such as an air source heat pump, is often a no-brainer for those looking for cheaper bills and a lower carbon footprint, but are they all they seem to be? As with everything, it's important to have a balanced view before buying, so let's go over the disadvantages of air source heat pumps.
air source heat pumps are really a stroke of
genius that fits well into the futuristic visions of our childhood. A box not much larger than a large armchair, it is effectively placed on the side of your property and magically transforms cold outside air into hot water, which fills your radiators and your entire underfloor heating system. Capable of converting air temperatures as low as minus 20 degrees and producing instant hot water in a home or storing it for later use, they also work in reverse.Surprisingly, they can even produce cool air similar to an air conditioning unit in the summer months. Some people even equip them in their pools to use them to heat the water there. Air source heat pumps can be installed in just a couple of days and can last up to 20 years. Requires minimal maintenance, needs cleaning every two months and annual service.
Perhaps best of all are the eco-friendly credentials of this impressive kit. An air source heat pump is able to match the entire repertoire of a traditional gas boiler, but it does so with minimal electricity and little damage to the environment. No need to store fuel, because it just doesn't work on fossil fuels. In fact, installing a heat pump with an air source and then powering it with electricity from other renewable sources, such as solar panels on the roof, means that it can be completely carbon neutral.
Possibly the most mind-boggling factor about the air source heat pump is that the government will pay you back in installments every month for up to 7 years as part of an incentive scheme for the UK to focus on renewables. As much as it sounds like something you might find in a Harry Potter movie, the reality of this air-to-water heating system contains intelligent technical engineering. How a heat pump works is the definition of efficiency. There are two key types of heat pumps: “air to water” or “air to air”.
A water heat pump is where heat from the air generates heat for water, which is then pushed around traditional heating systems, such as radiators and underfloor heating. As underfloor heating works better at lower water temperatures than radiators (approx. Air-to-water systems work by drawing air from outside into your body. This air is used to heat a liquid coolant, similar to how a refrigerator works, but vice versa.
Compressed liquid (now heated) releases stored heat and can be transferred throughout the house through normal heating systems such as radiators and underfloor heating. Finally, any excess heat is used to generate hot water from a cylinder. A double option on some models of air source heat pumps means that it is also possible to use them as an air conditioning system. Warm summer air can be converted to cold by absorbing heat from the air, which can then be returned to the indoor space by a fan system.
It is necessary to ensure that a house is well insulated to get the best out of an air source heat pump. This is largely to ensure that any heat is contained within the property and that temperatures are kept constant. Although it is totally possible to get away with a single small air source heat pump for an average 3-room house, sizing the air source heat pump is a job that only a professional renewable energy specialist can do. A heat loss report is an important part of the process of knowing how big you need to go, or even if an air source heat pump is enough.
In really big houses, it may be that the combined efforts of two heat pumps working in cohesion are needed. Other factors include the type of hot water cylinder you have and the number of radiators. The efficiency of the air source heat pump is also governed by the type of insulation and the amount of insulation you have. How much does this seemingly perfect product cost? Well, the good news is that out of all the available renewable energy heating systems you can install in your home, air source pumps are absolutely the most affordable option.
A good quality air source heat pump costs on average £4,000 to £5,000 (depending on your production range), but the installation costs of the air source heat pump can increase the price considerably. For the installation, you can expect to pay between 3000 and 10,000 extra pounds, depending on the complexity of the work, the existing infrastructure and the size of the property. Compared to the average cost of a biomass boiler (£15,000 to £20,000), or a land-based heat pump of £14,000 to £20,000, there is considerable savings. The latest announcement called “Future Homes Standard” detailed the total intention to move all new construction properties away from fossil fuels, addressing a much-needed reduction in carbon emissions for the UK to meet its CO2 2050 targets, so with the growth of the industry, it is expected that the air source the price of the heat pump will drop sharply, along with other renewable technologies.
When experts install them correctly (like here in Green Square), air source heat pumps are definitely cheaper than any oil or LPG boiler. The Coefficient of Performance (COP) is a way of defining how much energy production results from an energy input. When an air source heat pump uses 1 kW of electricity to operate, it has a COP of 3 kW. The 3 kW is thermal energy (heat).
These relationships change depending on the temperature of the air and also on the temperature of the water that the heat pump is trying to produce. Because it fluctuates over the seasons, an average COP is calculated over the course of a year, known as SCOP (Seasonal Performance Coefficient). These running costs are further reduced when a homeowner is part of the government's Renewable Heat Incentive Plan, which pays 10.71 p.m. per kW for air-source heating.
Throughout the 7 years, this is added to significant aid for payment and throughout the service life, you will definitely end up paying less than your counterpart gas boiler. As much as air source heat pumps are wonderful, nothing is perfect. As we know, air source heating systems come in two formats, the air-to-water heating system and the air-to-air heating system. Unfortunately, the initial cost is probably the main disadvantage of air source heat pumps.
Most people simply don't have, or feel able to pay the higher upfront costs. The cost of air source heating is largely dominated by the cost of installing the pump. Because renewable technology is still a fairly new industry, fewer people know how to do it compared to their fossil fuel alternatives. However, we would still argue that ASHPs generally work cheaper.
The fact is, when you think about how much an air source heat pump costs in total, you just have to wait a few years to recover your investment. A key drawback of air source heat pumps is that they simply do not provide the same level of heat that some homeowners expect. Although this sounds bad, it simply means that it is a heating system that is better suited to underfloor heating and radiators. Therefore, larger radiators are often required, which entails an additional installation cost that must be taken into account.
This slow and steady approach ends up being more cost-effective than constantly turning on the heating, as we have become accustomed to. That said, for households that are already connected to a main supply of gas at lower prices, you may find it cheaper to keep that. Another drawback of the air source heat pump is the noise it makes, which looks a lot like an air conditioning unit. Most people find that placing the ASHP as far away from quiet areas of the house (such as bedrooms) simply doesn't bother them, but if you're sensitive to noise, it can be a nuisance.
Fortunately, manufacturers are getting better and better, so newer models are quieter than ever, some make almost no noise. This includes ensuring that the installation is at least one meter from the boundary of your house, will be used only for heating, is installed on a suitable surface such as the floor or a flat roof (1 meter from the edge), has a maximum volume of. This could be considered an advantage of an air source heat pump on a hot day, of course, but in general we only recommend keeping barbecues and garden furniture away from the unit. The final disadvantage (if it could be considered as such), is the appearance of the air source heat pump, which tends to resemble an air conditioning unit.
Despite the similarities in their names, air and ground source heat pumps are very different creatures. We have a complete guide to the pros and cons of an air source heat pump compared to a ground source heat pump, which you can find here. When it comes to the air source heating system, Green Square has a lot of experience in almost every major brand.

The biggest disadvantage of an oven over a heat pump is that it cannot cool your home.
It can only emit warm air. Therefore, you will need to install an air conditioner in your home that you can use during the hot summer months. However, if you live in a part of the country where winters are extremely cold, think of a place like Chicago or Minnesota, then you may need a backup system to take care of heating your home when the heat pump can't. For example, it may be more expensive to buy a heat pump in early winter because the demand for this type of system is increasing.
In fact, you may not even be able to go into defrost mode, and if the heat pump continues to “try”, it will be damaged. The low amount of maintenance required by a heat pump is a benefit for homeowners looking for ways to save money on expensive home repair projects. If your house is poorly insulated and your budget is limited, start with insulation and forget about heat pumps for now. Well, the good news is that out of all the available renewable energy heating systems you can install in your home, air source pumps are absolutely the most affordable option.
Because they don't use natural gas, electric heat pumps don't have this problem and are generally safer in your home than gas ovens. We also wanted to mention some common heat pump problems that homeowners should be aware of before investing in such a unit. If you are analyzing the pros and cons of buying a heat pump, geothermal heat pumps require even more attention because you need to dig up the ground to install the system. If you're researching the pros and cons of buying a heat pump, you probably know that this type of system is designed to produce both hot and cold air.
