Heat Pump Installations
We work with you to design, install and maintain Air Source Heat Pump systems that prioritise efficiency, while ensuring warmth and comfort in your home.
We specialise in retrofit where we replace existing fossil fuel boilers and heating systems, taking on both complex and tricky projects in Bath and surrounding areas.

System Design
Performance begins with careful design.
The design of the system is by far the most important step in the successful installation of a heat pump to ensure it is reliable, efficient, and keeps you warm and comfortable. We take a meticulous and collaborative approach to each design stage:
1. Heat Loss Calculation
The heat loss calculation is the foundation of a well performing system.
We don’t just see this as an inconvenient box ticking exercise we need to get through quickly. But an opportunity to get to know the building and you. In our approach, we thoroughly assess your home and your needs to guide initial design decisions.
2. Initial Design
Once we have a heat loss calculation, we produce an initial system design that we discuss with you and mutually agree. This draft includes:
- The proposed make, model and size of the heat pump (how much heat it can produce);
- The maximum flow temperature the system will work at (the lower this temperature, the more efficient the heat pump will be);
- The room temperatures we want to maintain throughout the house – how warm you want your rooms to be;
- The number and size of radiators (depending on what you already have) and/or how any underfloor heating (new or existing) will work with the system;
- The provision of hot water;
- Discussing the extent of work required for the options together with proposed work plans and associated costs.
We see the design process as an iterative one and guide you through all these items so you can ask all the questions you need to make informed decisions about your new system and how it’ll work for you.
3. Technical Design
Once we’ve agreed the over-arching needs of your system, we get to work with the technical design.
This is the stage where we work out flow rates and pressure drops; determine the exact pipework needed through the whole system, so we know the new heat pump will deliver the heat needed throughout you home.
Various system components are then specified to finalise the design.
We will again talk you through this and explain anything you’re unsure about.
Get any of these stages wrong and you can end up with a system that either can’t heat your house when it’s cold, or a system that is over-sized and highly inefficient. You could also end up with a system that’s difficult to control.
Installation
Following agreement of the design, it’s time to get our hands dirty. This is where we start work on getting your new heat pump installed.
We will discuss and agree the scheduling of work with you so you’re clear about timelines.
The elements of installation work include:
- Remove and decommission your old boiler. Cap off the gas supply. Take out any existing hot water cylinder (if being replaced). Prepare the area for installation;
- We thoroughly clean the existing heating system before installing the heat pump. Then we clean and flush the system again as a final installation step;
- Ground works to provide a secure base with suitable condensate drainage for the heat pump;
- Install Heat pump and run all necessary pipework, power and control cabling to the heat pump;
- Where necessary, we’ll install your new unvented heat pump hot water cylinder;
- Install any upgraded radiators or underfloor heating;
- Complete all pipework installation, including meticulously insulating pipes to reduce heat losses.
Our work is carried out to the highest standards to comply with all relevant regulations, of course, and according to our designs for efficiency and comfort.
Commissioning
The commissioning of the heat pump system is an extremely important final stage, often rushed or overlooked.
It is during commissioning that the system is set up to run correctly in line with the original designs and involves the initial programming of the controls to adapt the heat output of the system according to the weather. This is key to efficiency and comfort.
Initial commissioning can take anywhere between several hours for small projects up to a couple of days for larger projects.
If the weather is warm on the day of commissioning we will schedule another commissioning visit for when the weather turns cold again.
Once commissioned on site, we remotely monitor and tweak the system over a number of months to optimise the system for you based upon your feedback on how you’re experiencing the system and comfort levels.
Maintenance
We provide all annual maintenance services for your new heat pump and heating systems to make sure the system continues to run reliably and optimally for years to come and to satisfy manufacturer warranty requirements.
