Whether you’re looking to replace your traditional gas boiler or upgrade to a more efficient system, installing a heat pump offers numerous benefits.
Not only do heat pumps reduce your reliance on fossil fuels, but they also integrate seamlessly with modern heating systems, including underfloor heating and larger radiators.
Your Heat Pump Installation – Preperation
Before you start the installation process, it’s crucial to get your home ready for a heat pump system. The first step involves enhancing your home’s energy efficiency.
This includes filling cavity walls, fitting double or triple glazed windows, and installing loft insulation. Implementing these measures guarantees the optimal operation of your new heat pump, ensuring a warm home and low energy bills.
Additionally, consider the following when installing a heat pump:
- Upgrade radiators to models compatible with heat pumps
- Assess the availability of space for an indoor hot water cylinder and possibly a buffer tank
- These components are essential for the system’s functionality and might not be feasible in smaller properties
- Obtain an Energy Performance Certificate (EPC) from an independent energy assessor before proceeding with the installation.
Assessing Home Suitability
It’s important to evaluate if your home is suitable for a heat pump system. Enhancing the efficiency of the heat pump system necessitates the upgrading of home radiators and improvement of insulation.
These upgrades ensure that your home retains the heat generated by the pump, providing consistent and comfortable indoor temperatures.
An energy performance certificate is a valuable tool for assessing your home’s energy profile and determining its compatibility with a heat pump system.
Following recommendations such as updating insulation or securing necessary planning permissions can further improve your home’s readiness for a heat pump installation.
Securing Permissions
Before installing a heat pump, it’s important to secure the necessary permissions.
Generally, heat pump installations do not require planning permission unless your home is a listed building or located in a conservation area.
To qualify for an exemption, the heat pump must be installed at least one metre away from the neighbour’s boundary.
Installers must comply with the Microgeneration Certification Scheme (MCS), ensuring that air source heat pumps placed at least a metre away from the property boundary are used exclusively for heating.
Additionally, homeowners are required to notify the local district network operator (DNO) prior to installation.
Heat Pump Installation Process
The installation process for a heat pump is comprehensive and methodical.
It begins with an initial assessment, which involves a heat loss calculation to determine the system specifications and the size and power of the heat pump.
This vital step guarantees that your new heat pump will meet your home’s heating needs efficiently.
The process is typically divided into three main stages: fitting the hot water cylinder, assessing existing radiators, and connecting all components.
Hiring a professional company for the installation is important for ensuring energy efficiency, system lifespan, and overall comfort, outweighing the potential initial savings from a DIY approach.
Site Inspection and Heat Loss Calculation
A thorough site inspection is the first step in the installation process. During this inspection, the professional installer will:
- Assess the size of your home
- Assess the number of rooms
- Assess insulation levels
- Assess the size of radiators
- Check for the presence of underfloor heating to determine the heat pump specifications.
A heat loss calculation is performed to understand how much heat your home loses, which is a critical factor in sizing the heat pump. The higher the heat loss, the larger the heat pump required. This step ensures that the system will provide adequate heating without overworking.
Installing the Outdoor and Indoor Units
The next step involves installing the outdoor and indoor units of the heat pump system.
The outdoor unit is typically installed just outside your home, close to an external wall, to effectively extract heat from the air or ground.
It can be secured to the ground using anti-vibration feet or wall-mounted, depending on the unit’s design and your home’s layout.
The indoor unit is mounted on an external wall using a bracket for stability. Cables and pipes are then fed through a hole drilled in the wall to connect to the outdoor unit, completing the setup.
Connecting and Testing the System
Once the units are in place, the heat pump is connected to your home’s heating network, which may include underfloor heating or radiators. After connection, a series of checks are performed to ensure the heat pump is functioning safely and properly.
Testing the heat pump operation involves verifying its integration and performance with the existing heating elements in your home.
Qualified installers offer warranties and after-sales support to ensure the long-term reliability of the system once the heat pump installed at the heat pump hub.
