Air Source Heat Pumps are rapidly becoming one of the most popular means of heating a home in Scotland and the UK, with their eco-friendly ability to save massive amounts of money attracting many people. We’ll talk you through how Air Pumps Work and how they can help you save on an energy bill.
What is an Air Source Heat Pump?
So just what exactly is an air source heat pump? It’s an eco-friendly way of heating the home. Using a small amount of electricity, it can take the air from outside your home and convert it into warm water or heat for radiators.
Kinds of Air Source Heat Pump
The Greener Energy Group offers two specific kinds of Air Source Heat Pumps. Air to Air, which takes heat from outside of your home and circulates it. It doesn’t provide hot water. Air to Water Heat Pumps however do and are a much more popular system as a result. While they need to be run longer than a traditional boiler, they provide just as much heat.
How Does an Air Source Heat Pump Work?
In a way, an Air Source Heat Pump works a little like a ‘reverse refrigerator’. The Air Source Heat Pump draws warmth from the air and transfers it into the heating system in your home.
For a little more detailed breakdown, the process can be divided into four distinct steps.
- The heat pump absorbs the heat. This is absorbed into tubes filled with a liquid refrigerant.
- The refrigerant is then compressed and becomes a warm gas.
- The heat is then passed into a heat exchanger. This can be surrounded by either cool air or water.
- The air or water becomes warm, and can be passed through your home, providing you with warmth and warm water
Air Source Heat Pump Installation
Most Heat Pumps are placed either at the back or the side of a property. They require a good amount of space – since the air must be able to circulate. You’ll need to ensure you have the proper space to get the air circulating.
Despite this, an Air Source Heat Pump is relatively easy to install. It’s much easier to install than a Ground Source Heat Pump, since those require a lot of digging work to lay down pipes.
So, are Air Source Heat Pumps efficient? Can they save me money and cut down on my C02 emissions?
With money, an Air Source Heat Pump can end up saving you a significant amount of cash in the long run. This isn’t just due to cutting down costly heating bills, but also the lowered cost of maintenance and long-life span of the Heat Pump.
Regarding C02, a Heat Pump will still produce some emissions if it isn’t using electrical power derived from a renewable source – but this is a relatively small amount. Ultimately, a Heat Pump is great for the environment because the heat it provides is converted from what’s already available. Now this this raises a bit of concern for some people; what if it’s cold outside? Well, an Air Source Heat Pump can draw heat even in cold weather (since there’s always a level of ambient warmth in the air for it to draw upon). Furthermore, the Heat Pump can store warmth and so you’ll never find yourself without heating.
We’ve spoken a bit about the fact an air source heat pump is eco-friendly, and this can’t be overstated. An Air Source Heat Pump only uses a small amount of electricity to operate. If this is powered by a renewable tariff, then the carbon output is cut down to zero. With a growing concern over the impact of heating the home on the environment, a heat pump is a highly attractive option.
A lot of heating systems can be maintenance heavy (especially boilers, which with their many moving parts can often require regular maintenance and costly insurance to keep running). Air Source Heat Pump’s don’t have this issue; they are low maintenance and the components required for repairs tend to be cheap. This is combined with their long service life; as a result, an Air Source Heat Pump is an excellent long-term investment. At the same time, you should aim to get a Heat Pump serviced once every 2-3 years. This ensures debris can’t build up and prevents blockages from occurring and helps to guarantee the Heat Pumps long life span.
Furthermore, there’s a huge number of different grants and schemes promoted by the government to make paying for an Air Source Heat Pump easier, such as Renewable Heat Incentive Payments. This can significantly lower or offset the overall cost of an installation, and in the long run make it a highly attractive investment.
