Can I Really Install My Own Underfloor Heating?
Yes, you can install your own underfloor heating, but it’s important to be aware of the scope of the project. Fitting the system yourself is definitely possible, especially if you’re comfortable with DIY tasks. Many homeowners successfully install the floor elements of underfloor heating, including placing the pipes or mats and securing them in position.
However, while DIY installation can save on labour costs, there are certain aspects where professional help is essential. For example, connecting the underfloor heating system to your boiler or mains supply, and ensuring everything is safely set up and tested, is best left to a certified plumber or electrician. This ensures that your system is not only safe but also efficient and long-lasting. So, while you can handle much of the work yourself, always get a professional to handle the final steps.
1. Choose the Right Type of Underfloor Heating
There are two main types of underfloor heating: wet (water-based) and electric (dry). Deciding which one is best for you depends on the room you're heating and your budget.
Wet underfloor heating connects to your central heating system and circulates warm water through pipes laid under the floor. It's ideal for larger spaces like open-plan areas and extensions. While installation can be a bit more involved, the running costs are typically lower than electric systems, making it a more cost-effective solution in the long run.
Electric underfloor heating uses electrical cables or mats to heat the floor. It’s easier to install than wet systems, making it a popular choice for smaller spaces such as bathrooms or kitchens. However, due to higher running costs, it’s generally better suited to smaller areas or occasional use.
Consider your room size, budget, and how often the space will be used when choosing between these two options. Larger areas benefit from wet systems, while electric options are simpler for smaller rooms.
2. Understand Heat Output Requirements
Before you start installing underfloor heating, you need to consider the heat output required for your space. Factors such as insulation, ceiling height, and the number of windows can affect how much heat your underfloor system needs to generate.
Well-insulated rooms with double glazing and proper wall insulation will retain heat more effectively, meaning your underfloor heating system won’t need to work as hard to keep the room warm.
Rooms with high ceilings or lots of windows may require a more powerful system to ensure the entire space is heated evenly. If the room isn't well insulated, much of the heat could escape, making the system less efficient and increasing your heating costs.
To get the best performance, assess your home’s insulation and consider using a higher-output system in areas that are harder to heat, such as conservatories or older properties.
3. Go for a Low-Profile System to Reduce Floor Height
If you’re installing underfloor heating in an existing space, one of the main concerns is likely to be the height of the finished floor. The good news is that there are low-profile systems designed to minimise floor build-up.
Systems like LoPro® are excellent for retrofitting because they add only around 15mm to the overall floor height. These solutions not only help maintain the room’s original dimensions but also avoid the need to modify doors or skirting boards.
Low-profile systems are also lightweight, making them easier to handle during installation. If you’re working on a DIY project, this can be a huge advantage, especially when it comes to moving materials into position without too much hassle.
4. Gather the Right Tools and Materials Before You Start
Preparation is key to a smooth DIY underfloor heating installation. Before you begin, make sure you have all the necessary tools and materials at hand. This will save you time and prevent frustrating interruptions during the process.
Here’s a basic list of what you’ll likely need:
Underfloor heating kit (pipes or electric mats)
Insulation boards
Pipe staples or clips (for wet systems)
Tape (for securing electric mats)
Manifold (for wet systems)
Screed (for levelling the floor)
Basic tools: hammer, tape measure, spirit level, and utility knife
For wet underfloor heating systems, make sure you also have a plan for the layout of the pipes. Follow the manufacturer’s instructions carefully, especially when spacing the pipes or cables to ensure even heat distribution across the room.
Additionally, if your system requires insulation or a damp-proof membrane, make sure these are installed correctly before laying the heating system. Failing to prepare the space adequately could lead to inefficiencies or even damage to the system over time.
5. Know When to Call in a Professional
Even if you’re an experienced DIYer, it’s important to recognise when professional help is needed. While you can install the floor elements of the underfloor heating system, setting up the final connections to your boiler or mains electricity requires expert knowledge.
For wet underfloor heating, a qualified plumber should connect the system to the manifold and boiler, ensuring that everything is properly pressurised and tested. Similarly, for electric systems, an electrician should complete the final wiring and make sure the system is safely integrated with your home’s electrical circuits.
This isn’t just about following regulations – it’s also about ensuring the system works efficiently and safely. A poorly connected system can lead to costly repairs, inefficient heating, or even safety hazards.
So, while DIY is a great way to reduce labour costs, always get a certified plumber or electrician involved for the final steps. It’s an investment that ensures your heating system runs smoothly and safely for years to come.
6. Consider Future Maintenance and System Efficiency
Once your underfloor heating system is installed, keeping it running efficiently is crucial to ensure long-term performance and to avoid unnecessary costs.
For wet systems, it’s a good idea to flush the pipes periodically to prevent blockages. This helps keep water flowing freely and ensures that your heating system operates efficiently.
Also, check for any leaks or drops in pressure, which could indicate an issue with the system.
For electric systems, it’s less about maintenance but more about monitoring performance. Make sure the system isn’t overheating or being obstructed by heavy furniture, which can trap heat and cause inefficiencies.
Regardless of the type, a well-maintained underfloor heating system can help lower your energy bills by distributing heat more evenly. It’s also important to regularly review your thermostat settings and adjust them according to the season to maximise efficiency. In some cases, smart thermostats can be a great investment, allowing you to control the temperature remotely and schedule heating times based on your daily routine.
With proper care and regular checks, your underfloor heating system should continue to deliver consistent warmth and comfort for many years to come.
