Underfloor heating systems are becoming quite popular nowadays because of their energy-efficiency. Since many homes today use condensing boilers, it is natural and practical to consider renovating floors and adding radiant heating. But to ensure the success of the system, you need to follow some best practices, especially when it comes to choosing a floor screeding material. The performance of the system will be significantly affected by the layer of screed added before installing the flooring material.
Liquid screed is considered the most compatible with underfloor heating systems. Unlike ordinary cement, liquid screed completely covers the pipes ensuring maximum thermal performance. Liquid screed is also easy to install if you contact a reliable supplier like liquidscreed.co.uk. The mixture comes in a lorry and is ready to be pumped into the floor base.
Make sure that the subfloor is clean before installation
Heating pipes are durable and built to last. But to ensure that there are no sharp or hard edges that could cause damage, clean the concrete floor base first. It is also ideal to level out any lumps and bumps before installing the system and pouring the screed. A moisture barrier or layer of plastic may be added first along with the insulation for extra protection.
Follow the correct installation sequence
The manufacturer typically provides a step-by-step guide on how to install the heating system. Usually, you begin by installing the manifold so that you can estimate the weight before eventually adding the pipes. If you are hiring an expert for the installation, make sure that there is an electrician on-site to oversee all electrical connections.
Take note of the recommended maximum temperature in relation to the type of flooring
It is essential to consider the flooring material you are going to use because each type has a maximum allowable temperature. For example, if you are using wood, vinyl, or laminate, the maximum allowed temperature is only 27 degrees. The heating installation company should have detailed information on this aspect so that you can choose the right kind of flooring material based on your preferred maximum temperature.
Do not forget the insulation for improved energy-efficiency
The efficiency of any heating system is greatly affected by insulation. Some people try to save by doing away with insulation. Unfortunately, you will lose a lot of the heat and consume more energy without it.
Take time to plan
During the planning stage, measure the floor area several times before proceeding with the installation. Consider fixtures, especially for bathroom underfloor heating. If you want the heating to radiate into the toilet and towel rods, the pipes need to be fixed on the floor in the precise area where the fixture will be mounted. If the base flooring is made of wood, make sure to fix any creaks as it will be tedious to make repairs once the pipes have been installed.
Test the heating system
During the installation process, you need to test the heating system in stages. For example, while adding liquid screed over the pipes, you need to add heat gradually to see how the mixture will react. Testing is also critical so that the electrician can spot and fix any issues before installing the floor finish.
