Quick Guide to Underfloor Heating

Underfloor heating (UFH) is an efficient and comfortable way to heat a home or business, providing consistent warmth across a space. There are two primary types: wet (hydronic) and dry (electric). Here’s what you need to consider before installation.

1. Types of Underfloor Heating

Wet (Hydronic) Systems

• Uses water heated by a boiler or heat pump, circulated through pipes beneath the floor.

• Best suited for new builds or major renovations due to the need for subfloor installation.

• More efficient for heating large areas and entire buildings.

• Higher initial installation cost but lower long-term running costs.

Dry (Electric) Systems

• Uses electric heating mats or cables laid beneath the floor surface.

• Easier and faster to install, making it ideal for retrofitting existing spaces.

• More suited for smaller areas like bathrooms or kitchens.

• Lower upfront cost but higher ongoing energy consumption compared to wet systems.

2. Considerations Before Installation

Floor Type & Insulation

• Works best with materials that conduct heat well, such as tile or stone.

• Carpet and wood flooring should be UFH-compatible and not too thick to allow heat transfer.

• Good insulation is crucial to prevent heat loss and maximize efficiency.

Room Size & Heating Requirements

• Larger areas benefit more from wet systems, while small spaces may be better suited to electric heating.

• Consider whether UFH will be the primary heating source or used as supplementary heating.

Installation & Costs

• Wet systems require professional installation and integration with an existing heating system.

• Electric systems can often be DIY-installed (though a qualified electrician is needed for final connections).

• Costs vary based on system type, floor preparation, and required insulation.

Best For	Whole buildings	Small rooms
Installation Complexity	Complex	Simple

4. Final Tips

• Always consult a professional to assess feasibility, energy efficiency, and costs.

• Ensure your flooring is compatible with UFH to avoid heat loss and system inefficiency.

• Consider integrating UFH with a smart thermostat for better control and energy savings.

Underfloor heating can add luxury and efficiency to your home or business, but choosing the right system and planning the installation properly are key to long-term success.
