(Smiling) Hey everyone, welcome back to my channel! Today, we’re diving deep into the world of underfloor heating, specifically focusing on the often-overlooked but crucial aspect: pipe selection.
Now, you might think all pipes are created equal, but trust me, when it comes to underfloor heating, the right choice can make a world of difference in terms of efficiency, comfort, and even cost.
In this video, we’ll be exploring the different types of pipes available, their pros and cons, and the key factors to consider when making your selection. We’ll also be discussing common mistakes to avoid and offering some expert tips to ensure you choose the perfect pipes for your underfloor heating system.
So, whether you’re a seasoned DIYer or just starting to explore the world of underfloor heating, this video is for you. Let’s get started!
When it comes to underfloor heating, the choice of pipes is crucial for ensuring efficient heat distribution and long-term performance. Several types of pipes are commonly used, each with its unique characteristics and advantages.
Polyethylene (PE) pipes are known for their flexibility, making them easy to install around corners and bends. They are also resistant to corrosion and chemicals, ensuring a long lifespan. However, PE pipes have a lower maximum operating temperature compared to other options.
Polypropylene (PP) pipes offer excellent heat resistance and are suitable for high-temperature applications. They are also lightweight and easy to handle, making installation a breeze. However, PP pipes can be more susceptible to damage from UV exposure.
Copper pipes are a traditional choice for underfloor heating due to their high thermal conductivity and durability. They can withstand high temperatures and pressures, making them ideal for demanding applications. However, copper pipes are more expensive than other options and require specialized tools for installation.
Metalloplastic pipes combine the flexibility of plastic with the strength of metal. They consist of an inner layer of aluminum sandwiched between two layers of plastic. This combination provides good thermal conductivity and resistance to corrosion. However, metalloplastic pipes can be more prone to kinking than other options.
Corrugated pipes are a newer type of pipe specifically designed for underfloor heating. They feature a unique corrugated design that increases their surface area, improving heat transfer. Corrugated pipes are also flexible and easy to install. However, they may be more expensive than other options.

The best type of pipe for underfloor heating depends on several factors, including the specific application, budget, and desired performance. For example, if high temperatures are required, polypropylene or copper pipes would be the best choice. If flexibility and ease of installation are priorities, polyethylene or corrugated pipes might be more suitable.
Each type of pipe has its unique characteristics that influence its suitability for underfloor heating. These characteristics include:
- Maximum operating temperature: This refers to the highest temperature the pipe can withstand without compromising its performance or safety.
- Pressure rating: This indicates the maximum pressure the pipe can handle without leaking or bursting.
- Thermal conductivity: This measures how well the pipe conducts heat.
- Flexibility: This refers to the ease with which the pipe can be bent and maneuvered.
- Corrosion resistance: This indicates the pipe’s ability to resist damage from chemicals and other corrosive agents.
- UV resistance: This measures the pipe’s ability to withstand exposure to ultraviolet radiation.
The correct pipe size for underfloor heating is crucial for ensuring efficient heat distribution. The calculation of the required pipe diameter depends on factors such as the floor area, heat output, and desired water flow rate. Specialized software or online calculators can assist in determining the appropriate pipe size for a specific application.
The installation of underfloor heating pipes involves several steps, including:
A layer of thermal insulation is essential to prevent heat loss downwards and ensure efficient heat distribution within the floor. The type and thickness of insulation will depend on the specific application and building regulations.
A waterproof membrane is installed over the thermal insulation to protect the pipes from moisture and potential leaks. The type of waterproofing membrane will depend on the specific application and building regulations.
The first step in installing underfloor heating is laying and fixing the pipes. This can be done in a variety of ways, but the most common method is to use a staple gun to secure the pipes to the subfloor. The pipes should be spaced evenly, and they should be laid in a continuous loop. This will ensure that the heat is distributed evenly throughout the floor.
There are a few different components that are needed for underfloor heating. These include:
- Pipes: The pipes are what carry the hot water from the boiler to the floor. They can be made from a variety of materials, but the most common are metal-plastic and cross-linked polyethylene (PEX).
- Manifold: The manifold is a distribution center that connects the pipes to the boiler. It allows you to control the flow of water to different parts of the floor.
- Circulation pump: The circulation pump circulates the hot water through the pipes.
- Thermostat: The thermostat controls the temperature of the water in the pipes.
There are a few potential problems that can occur with underfloor heating. These include:

- Leaks: Leaks can occur in the pipes or the manifold. This can cause water damage to your home.
- Air locks: Air locks can occur in the pipes, which can prevent the hot water from circulating properly.
- Uneven heating: The heat may not be distributed evenly throughout the floor, which can cause some areas to be hotter than others.
Here are a few tips from experts on underfloor heating:
- Use a qualified installer: It is important to use a qualified installer to install your underfloor heating system. This will ensure that the system is installed correctly and that it will work properly.
- Choose the right type of pipe: The type of pipe you choose will depend on the size of your home and the type of flooring you have.
- Get regular maintenance: It is important to get your underfloor heating system serviced regularly to ensure that it is working properly.
