Air-source heat pumps are becoming more popular in homes for warmth, cooling, and hot water. They save energy because they don’t need fuels to heat or cool. Air source heat pumps get power from natural air, which is better for the planet. They also help people save a lot of money on their energy bills.
An air source heat pump installation is easy, but there are a lot of steps that need to be taken. The first step is to buy the heat pump from a reputable source. An indoor unit and an outdoor cooling unit make up an air-source heat pump. They take in heat from one place and move it to another. Because of this, it’s great for cooling and heating your house. The heat pump uses vapour compression cooling to move heat from one place to another with a system of coolants that soak up the heat.
Air source heat pumps are versatile, so you can use it in several ways, from underfloor heating to hot water-filled radiators. If installed correctly, it could also be a source of hot water and heating for your home. To get the most out of an air-source heat pump, choose the right one for your home and install it properly. In this blog, we will look into the complete details on air-source heat pumps installation process, how long it takes, what it costs, and so on.
What is an Air Source Heat Pump?
An air source heat pump (ASHP) is a device that can move heat outside and inside the house, i.e., it can perform heating and cooling tasks. An ASHP uses a refrigerant system that consists of a compressor and condenser to take heat from the inside surroundings and release it outdoors, and vice versa.
For domestic heating, the air-source heat pump takes heat from the outside and moves it into the inner area as hot air or domestic hot water supply. ASHP does the reverse during summer. It takes heat from the indoors and moves it outdoors.
How Does the Installation Process Work?
A standard air source heat pump installation method has a set of steps that installers must follow. As every property has a different structure, installing an air source heat pump can vary slightly based on whether it is an upgrade or a new build. Thus, it is essential to select a professional installer to do this job. Let’s explore the main steps involved in the installation process:
- Pre-installation
- Installation
- Post Installation
Air Source Heat Pump Installation Process and Working
The diagram below indicates the installation process and the design of an air source heat pump in the average house. The initial process stays the same whether you install an air-to-air or air-to-water heat pump. The system comprises a standard outdoor unit that varies in size directly and in output. Indoor units differ depending on the type of air source heat pumps, and they can be connected to radiators, underfloor heating, or other indicators to heat your building. A floor-standing hot water cylinder will also store hot water for your water supply.
Pre-Installation Work, On-site Survey and Preparation
After contacting the eco4 installer, the first step is to schedule an on-site assessment to determine whether your house is ready for the selected heat pump installation.
A professional installer has the expertise to safely remove any current system, including gas or oil boilers. The amount of heat loss will be calculated to establish the required heat pump size for installation. Inspection is a crucial stage in adequately planning the installation!
After completing this, the installer will plan and create a report that includes property designs for effective system installation. Based on your home’s insulation, heating requirements, and property size, the installer will recommend a suitable air source heat pump size. Once you are satisfied, the installation procedure will start, and the installer will have everything required to proceed safely to the next phase. The transition to a sustainable future has finally begun!
Installation of Indoor and Outdoor Units
An air source heat pump installation is relatively simple, as the heat pump controls and pipes are similar to standard heating systems. As previously stated, the system consists of indoor and outdoor units that must be installed.
The outside unit gets air from outside and compresses it into warm air. Indoor units like hot water tanks are placed and connected to radiators, ground heating, and hot water pipes. The hot water cylinder will usually be placed where the old boiler system was (if available), as it needs a similar space. They can be physically significant, so that room will be required, but the installer will handle all of this during the design and planning stage.
While installing the outdoor unit, the installer will choose an area with ample airflow and minimal obstacles. The unit will be bolted to the ground and fastened with brackets so it does not move even when windy. As an air-source heat pump movement is crucial to making this system work correctly, so placing this outdoor system is vital.
Connecting the Units
The indoor tank and the outdoor unit need to be wired and linked. The indoor unit will be connected to the radiators and other systems where heat is discharged inside the home. Depending on your building and the distance between the indoor and outdoor units, wires will need to be made by generally drilling a hole in a wall. The installer will then connect them through refrigerant lines and electricity wires. Don’t worry, however. These holes, lines, and connections will all be performed to the best of standards, with any mess cleared up and no signs left!
Post-Installation Work - Finishing Fixes and Maintenance
Once the installation has been completed, some final fixes will be required to ensure the heat pump system works efficiently. Most air-source heat pumps contain sensors, so these need to be installed so that the heat pumps may send temperature signals to your thermostat. This is an essential step as the precision of the sensors/heat pump system requires being spot on.
You can also discuss maintenance requirements at this time. Though air source heat pumps have low maintenance requirements, monitoring the filters and cleaning the fans regularly is strongly suggested. It ensures the heat pump runs appropriately throughout its long lifespan, up to 25 years!
What is the Average Time to Install an Air Source Heat Pump?
The time required to complete ASHP installation is still being determined. It depends on the installer’s competence, the size of your home, the weather, and the difficulties during the installation process. These could include air vent changes, wiring difficulties in your home, and the installation of additional devices. On average, it will take two to five days, but it may be a full day’s work for small homes.
How Much Does It Cost to Install an Air Source Heat Pump?
The cost of installing an air-source heat pump depends on several factors, such as the heat pump model, size, and the complexities involved in the process. For a rough estimate, the cost can be between £7,000 and £9,000. However, installing the ASHP with other home improvement projects can lower costs.
While you might think the installation cost is high, consider the cost-effectiveness and savings, thanks to lower energy bills and incentives.
Free Air Source Heat Pump Grants in the UK
Installing air-source heat pumps is becoming more accessible, with government schemes launched to promote low-carbon heating solutions. The Energy Company Obligation (ECO4) Scheme is a leading programme in the UK that aims to provide free air source heat pump grants to low-income families.
Is It Possible to Install an Air Source Heat Pump DIY?
Installing an air source heat pump comprises multiple procedures, not all of which can be done yourself. You can install the outdoor and indoor units to lower the construction cost. However, this may require some knowledge, resulting in a difference from a professional’s.
However, connecting the units and wiring them requires a licensed engineer with training and experience, as it can be complicated. Since an air source heat pump lasts over two decades, it is best to invest in a sound installation. That will not cause complications and increase your costs over the years. It becomes essential to hire a registered installer to do this job. Moreover, an MCS-certified engineer will install your heat pump if you qualify for the heat pump grants.
