A renewable heating system offers a lot of benefits to both residential and commercial properties. From a clear energy balance to long-term savings, there are countless advantages of using a renewable heating system. There are two types of heating system that is prevalent in the UK:
ASHP systems use outside air to distribute heat indoors. Most people prefer the ASHP system because of limited outdoor space. There is no need to dig or drill the ground to install this unit. All that is required is some space to install the external fan unit.
GSHP, on the other hand, extracts heat from rocks, river beds, and surface soil. It is slightly complicated to install the entire unit because it requires shallow trenches and a deep borehole that contain the inner unit. This helps the system to absorb the ground heat, which is transferred to the heat exchanger in the property. A significant benefit of this system is it requires low maintenance.
What Are Hybrid Heating Systems?
Apart from the above-mentioned types of heating systems, there is another set up known as a hybrid heating system. Experts also call it a dual fuel unit. It uses a combination of fossil fuels and renewable energy to heat the property. One of the components of this system is the heat pump used in ASHP or GSHP units, while the second component is LPG or traditional gas. This is why it is known as a hybrid heat pump because it combines two systems into one so that it can maintain the heating efficiency throughout the year.
Hybrid heat pumps are designed to suit the heating needs of people while keeping in mind to cut down the energy use and also save a significant amount of money on utility bills. The reason why most people prefer this system is it is more efficient than all the other types of heating systems. It conveniently switches between fossil fuel and renewable energy depending on the efficiency and need of the user. This makes sure that the user feels comfortable whenever the heat pump is on, but without compromising on the performance of the machine.
Hybrid heat pumps operate according to the outside temperature. If it is not too cold outside, the system will use low energy to keep the house warm enough to make the user feel comfortable. When the temperature dips outside, the heat pump will switch to the fossil fuel boiler instead of working on renewable energy. This generates heat faster so that the user doesn’t feel too cold in the winters.
What Are the Benefits of a Hybrid Heating System?
As already mentioned, hybrid heat pump systems have numerous benefits due to which they have become the need of the hour for many people, especially the ones who experience chilly winters. The main benefits are listed below.
People can use this system throughout the year. It can keep the rooms cold during autumn and summer. On the other hand, when winter arrives, it will convert from an air conditioner to a heater to keep the house nice and warm. Depending on the outside conditions, the operating system of the pump will change. It will start the traditional system to heat the rooms and also reduce the pressure of the renewable energy system.
The longevity of the heating system is another reason why hybrid dual fuel pumps are popular. Since this works on a hybrid system, both the traditional and renewable energy will not be pressurized. This not only improves the efficiency and life expectancy of the heating unit but also makes maintenance much easier. The hybrid setup will make sure that the heating system doesn’t become inefficient or tired and eventually, breakdown. Heat pumps usually last for years, but with a hybrid system, people can expect a longer life than regular heating units.
Heat pumps tend to use up a lot of energy. This increases the monthly energy bills to a great extent, especially during the winters. But, when there is a hybrid heat pump, it uses renewable energy that saves doesn’t involve fossil fuels all the time. This helps to save a significant amount of money on energy bills every month. Experts believe that hybrid heating systems can save as much as 30 to 50% of the energy bills that homeowners would usually pay if they use a traditional heat pump.
What Are the Disadvantages of a Hybrid Heating System?
While hybrid dual fuel heating pumps are known for their many benefits, people should also know about some of the disadvantages of this system. Here are a few cons that everyone should be aware of.
Using Fossil Fuel
Albeit the fact that it is a hybrid system and the pump will use renewable energy most of the time, it is impossible to deny the fact that it still uses fossil fuel which is highly expensive. When the world is moving towards smart renewable heating system, this technology may not be fruitful in the long run, especially when the aim is to remove fossil fuel from all the commercial and residential properties in the UK.
The installation cost is usually high when it comes to hybrid heat pumps. A hybrid system is installed when the house or the property already has a traditional heating system. But, if an entirely new installation is considered, the cost to install two systems will be quite expensive compared to installing a boiler or a heat pump. On the other hand, if a user considers the long-run efficiency of the system, it will help them save a lot. With lower utility bills, it will balance out the installation cost only in a few years. Since the user will not require the fossil fuel system to work throughout the year, he/she can expect to save later even though the installation may seem expensive.
It is always wise to consider the time or the number of years a person wants to live in the property. Hybrid systems are always beneficial in the long run that will add to the value of the house if it is put up for sale. Those who are planning to live in the home for a short time, it is wise not to invest in this system due to the high initial cost.
How Much Does a Hybrid Heating System Cost?
Installing a new boiler will usually cost around £500 to £2500. However, it depends on the size of the property and the money that the user wants to spend. If the user wants a combination of air source heat pump with a hybrid heating boiler, the total cost will be approximately £5,000 to £10,000. This will include the cost of installation also. Ground source heat pumps usually cost around £13,000 to £20,000, including the integration and installation of the hybrid system.
It is always wise to use heat pumps alone. But, if the house already has a traditional heating system and the user wants to save on energy bills, then a hybrid system will be highly beneficial. These systems are allowing homeowners to shift to a new type of heating system that not only uses renewable energy but also lasts longer than other heat pumps. Its energy efficiency and ability to provide the much-needed comfort to the user are a few reasons why people prefer to install it even if the initial set up cost is higher than traditional heating systems.
