The financial aspects of underfloor heating: A breakdown of installation fees and operational expenses you may incur

Underfloor heating is a discreet and effective replacement for conventional radiators, offering a more even distribution of heat in your home. However, before making the switch, it's essential to understand the costs associated with different types of underfloor heating systems, particularly electric ones.

Electric underfloor heating systems can vary in cost, with an average range of around 20 to 75 euros per square meter. The most common electric systems include electric foil and mat systems, cable heating systems, infrared heating films, and thin-bed surface heating systems. The costs for each of these systems typically range from about 20 to 50 euros per m² for electric floor heating and from about 50 euros per m² upwards for infrared heating.

Cable electric underfloor heating, for example, costs around £27/m2, while foil electric underfloor heating can range from £54/m² to £85/m². Mesh and mat electric underfloor heating systems also fall within this price range.

It's important to note that the costs for installing an electric underfloor heating system can also vary, depending on factors such as size, type of system, and installation complexity. For instance, a small room requiring only a two-port manifold starts at £100, with a more complex 12 port costing £375. A pump and mixing unit will be on average £250.

When considering costs, it's not just about the initial installation. You should also look at both the current and future costs, including the time of any off-peak tariff and whether you have spare capacity from any solar panels. Electric underfloor heating systems are not on all day, as the thermostat will only call for heat when it is required. For a rough estimate, use 50%, and probably less in a new build.

In comparison, water-based underfloor heating systems are usually more costly and intricate to install than electric systems, frequently necessitating significant alterations to the flooring and the heating system already in place. The costs for installing a water-based system will depend on the type of build situation - is it a newbuild or deep renovation for example. For a DIY installation of a water-based system, budget for material costs of £55 to £80/m2 for an average house.

Remember, both water-based and electric underfloor heating systems will also require a separate heat source, such as a combi-boiler, an air source heat pump, or a ground source heat pump if you are considering using renewable energy.

Underfloor heating improves energy efficiency, potentially resulting in cheaper heating costs in the long run. If you're considering a DIY installation or hiring a professional, it's essential to get accurate quotes from multiple providers to ensure you're making the best decision for your home and budget. The Warmup website suggests you can pay anything from £100 - £300 a day for an installer, and that an area of 40m2 will take around 2-3 days to complete. The cost of electricity is currently 24.5p per kilowatt hour (kWh).

In conclusion, while electric underfloor heating systems may have a higher upfront cost compared to water-based systems for larger areas, they offer a discreet, effective, and energy-efficient heating solution for your home. By understanding the costs associated with different types of electric underfloor heating systems and installation methods, you can make an informed decision that best suits your needs and budget.
