Find a leak in underfloor heating

Get a Quote

Water leaks in underfloor heating are common but hard to find. Even a small leak can damage your floor, insulation, and reduce heating efficiency. Typical signs include pressure loss, frequent water refilling, or uneven floor temperature. As underfloor heating specialists, we use non-destructive leak detection to locate the exact problem — without breaking the floor. Our precise diagnostic methods help you find and fix the leak quickly, saving both time and repair costs.

Description

How We Find Water Leaks Under a Floor

1. Preparation and System Check

Pressure testing: determines if water loss exists in the heating system.
Loop identification: isolates which heating loop or zone is affected.
Leak location mapping: marks the suspected area for precise testing.

2. Advanced Diagnostic Methods

Acoustic Leak Detection

We use highly sensitive microphones and sensors to listen for leak sounds through flooring materials — concrete, tiles, or wood. This allows us to pinpoint the leak with up to ±30–70 cm accuracy.

Tracer Gas Method (Hydrogen/Nitrogen)

A non-toxic tracer gas is gently injected into the heating circuit. The gas escapes through the damaged section, and a digital detector identifies the exact point above the floor.
This method is ideal for locating leaks hidden under tiles or screed where visual access is impossible.

By combining both methods, we can accurately locate even the smallest leaks — without damaging the floor or structure.
