The Ultimate Guide to Choosing the Best Floor Heating Pipe for Your Home (2023)

When it comes to heating your home efficiently, floor heating systems are a top choice. Among the various options available, floor heating stands out for its ability to provide three-dimensional heat dissipation, ensuring a constant temperature in your room even during the chilliest seasons. Before you dive into the world of floor heating, it’s crucial to understand the essentials. In this comprehensive guide, we will walk you through everything you need to know about underfloor heating systems and help you choose the best floor heating pipe for your home.

What is Floor Heating?

Floor heating involves the installation of pipes within the floor, transforming the entire floor into a radiator. This innovative system works on the principle that warm air rises above colder air, making your room exceptionally comfortable. Unlike traditional radiator systems that operate at high temperatures, floor heating systems maintain a lower operating temperature of about 40 degrees Celsius. This lower temperature, combined with the even heat distribution through pipes under the floor, creates a cozy ambiance without the need for excessive airflow.

Types of Underfloor Heating Systems

There are two main types of underfloor heating systems:

1. Wet Underfloor Heating (Warm Water Underfloor Heating)

Wet underfloor heating systems utilize pipes filled with warm water, powered by either a heat pump or a boiler. These pipes are concealed under the floor, buried into the screed. This system is ideal for whole-house installations and new builds due to its exceptional energy efficiency and low running costs. It can also be surface-mounted using specialized pipes, providing flexibility in installation.

2. Electric Underfloor Heating

Electric underfloor heating systems are easier and more cost-effective to install compared to wet systems. They are connected to your home’s electric circuit and controlled via thermostats. While they are suitable for specific areas like bathrooms, their overall energy costs are higher than wet underfloor heating systems.

Types of Floor Heating Pipes

When choosing floor heating pipes, consider the following types:

1. PE-RTPB Pipes

PE-RTPB pipes, made of polyethylene, offer uninterrupted energy-efficient heating for residential, commercial, and industrial buildings. They are flexible, easy to install, and resistant to freezing. Designed specifically for water-based underfloor heating systems, these pipes are non-corrosive, frost-resistant, and environmentally friendly, making them an ideal choice for floor heating.

Depth and Installation of Floor Heating Pipes

The depth at which floor heating pipes should be laid depends on the pipe size and the type of flooring in your home. For efficient heating, adhere to the following guidelines:

  • For timber floors, the maximum heat output is 70 W/m², and pipes should be laid at an appropriate depth.
  • For concrete floors, the maximum heat output is 100 W/m², requiring pipes to be laid deeper for optimal performance.
  • Proper insulation and correct spacing between pipes are crucial for maximizing heat distribution and ensuring each room receives the necessary warmth.

Choosing the Right Floor Heating Pipe: Key Factors

When selecting floor heating pipes, consider the following factors:

1. Heat Conduction Efficiency

Install the underfloor heating system in well-insulated areas to ensure optimal comfort and heat conduction efficiency.

2. Flexibility

Choose ultra-flexible underfloor heating pipes for quicker and more flexible installations, speeding up the process significantly.

3. Stability

Opt for pipes made from high-temperature-resistant materials to guarantee stability and reliable connections, preventing leaks and ensuring longevity.

4. Lifespan

Select pipes with a projected lifespan of at least 50 years to ensure durability and long-term functionality.

5. Compatibility

Ensure the chosen system is compatible with alternative energy sources, allowing you to integrate sustainable energy solutions seamlessly.

6. Installation

Consider the installation method, keeping in mind the distinct procedures for wet and electric underfloor heating systems. Choose a system that aligns with your installation requirements and preferences.

7. Cost

Evaluate the overall installation costs, including materials, labor, and long-term energy expenses. Balance affordability with quality to make an informed decision.


Floor heating systems have revolutionized home heating, offering energy-efficient solutions with low running costs. Whether you opt for a wet underfloor heating system for comprehensive home heating or an electric system for specific areas, the key lies in choosing the right floor heating pipe. By considering factors such as heat conduction efficiency, flexibility, stability, lifespan, compatibility, installation, and cost, you can make a well-informed decision. Invest in a high-quality floor heating pipe, and enjoy the unparalleled comfort and warmth it brings to your home.
