Eco Friendly Foil Underfloor Heating
Eco Friendly Heating and Flooring supplying Warmups Foil Heater. This underfloor heating system is an energy-efficient electric underfloor heating solution designed to deliver even, comfortable warmth throughout your space. The reinforced aluminium foil layer ensures consistent heat distribution, helping you enjoy an eco-friendly, efficient, and cost-effective heating experience.
Whether used as a primary or secondary heat source, our foil heating mats are suitable for most rooms and comply with current Building Regulations.
How Does the Foil Heating System Work?
The foil layer serves a dual purpose — it acts as a continuous earth layer within the floor construction while spreading the heat evenly across your floor surface. Because it’s installed directly beneath your floor finish, there’s no need for self-levelling compounds, making installation simple and mess-free.
The result? A safe, efficient, and evenly distributed radiant heat that feels natural underfoot.
Ideal Room Shapes and Installation Flexibility
Foil heating mats are particularly suitable for regular-shaped rooms, as the 0.5m-wide mats can easily be rolled out in parallel runs. When needed, the mat can be cut, turned, and flipped to fit your space — without affecting the heating cable.

Best Flooring Types for Foil Heating
Foil underfloor heating is the ideal solution for floating floor systems, including:
- Laminate Flooring
- Vinyl Flooring
- Engineered Wood
-
Carpet (when used with a Dual Overlay System)
Using Softer Floor Coverings
If you’re using softer floor finishes such as vinyl or carpet, the Foil Heater must be paired with the Dual Overlay System.
This protective subfloor allows heat to pass through efficiently while safeguarding the foil heater — ensuring maximum comfort and long-term reliability.
Engineered Wood and Laminate Flooring Compatibility
Our Foil Heating System works seamlessly with engineered wood and laminate flooring, providing fast and efficient heat transfer with minimal installation height.
Please note:
-
Avoid wood thicker than 18mm.
-
Avoid any flooring with metallic locking strips or attached underlay, as these can interfere with the foil mat.
-
Always confirm with your flooring supplier that your chosen product is suitable for electric underfloor heating.
The total thermal resistance of your flooring should not exceed 0.15m² K/W to ensure optimal performance.
Using Vinyl or Carpet with the Dual Overlay System
When using vinyl or carpet, our Dual Overlay System. creates a stable, protective layer above the heating mats.
This “floating” subfloor ensures efficient heat transfer and protects the heater from damage caused by heavy furniture or foot traffic.
⚠️ Please note: Dual Overlay is not suitable for wet areas, such as bathrooms or wet rooms, as excessive moisture can cause expansion. For wet rooms, consider electric systems like DCM-PRO, StickyMat, or Loose Wire systems embedded in a self-levelling compound.
Importance of Proper Underfloor Insulation
For the best performance, your subfloor should have adequate thermal insulation before installation. Insulation prevents heat loss and improves the efficiency of your system — reducing energy consumption and running costs.
We recommend using our underfloor insulation materials, which help cut heat-up time by up to 50%, significantly lowering energy bills.
The foil heater should always be installed on top of a suitable soft insulation layer (at least 6mm thick) to protect the cable from pressure damage caused by furniture and footfall.
Installation Overview
Installing the Foil Heater is quick and straightforward:
-
Roll the foil mats out across the floor in parallel runs.
-
Maintain 20mm spacing between runs and at least 50mm from walls.
-
Use the provided foil strips to bridge any gaps when cutting or turning mats — this keeps the electrical earth continuous.
-
Ensure the foil mats are completely flat (never folded or creased).
For laminate or engineered wood floors, your chosen floor finish can be laid directly on top.
For vinyl or carpet, install the Dual Overlay System between the heater and the final floor surface.
