Fitting electric underfloor heating: how the job goes

What the rule says

In Wallonia and Flanders, the rule limits direct electric heating, and names electric underfloor heating. Wallonia: 2,500 W at most per home up to 150 m², then 15 W per additional m², on any fitting, appliances already in place included. Flanders: 15 W at most per m² in a renovation subject to a permit or a notification with an architect; in an extension, the cap is calculated on the extension alone. Brussels: we have not found a cap. One room remains possible; a whole home, not within these limits.

In Luxembourg, direct electric heating cannot be the main heating of a building that is new, extended or converted. Partial heating remains possible: the regulation cites the bathroom.

In the Netherlands, a heating system that is fitted or renewed must reach a performance that direct electricity does not reach. The guide published by the public agency RVO rules out electric underfloor heating as main heating; the agency’s page allows local electric appliances controlled room by room. For a room heated as a supplement, the official documents point towards local heating being allowed, without naming electric underfloor heating: to be confirmed by the municipality.

The rule, country by country, with the texts

Before: the design

Main heating is not laid by the metre. It is calculated, room by room.

You give us the floor areas or the plans, the clearance available under the doors, the floor covering you want, and the condition of the floor.
We work out the demand of each room, then the laying plan: what is covered, that is 75 to 85% of the floor area, the output, the position of the thermostats, the electrical lines.
We check the floor: dry, sound, flat to within 2 mm over one metre. If it is not, a levelling compound comes first.

On fitting day

The old floor covering stays in place if it holds firm.
The reflective layer is rolled out, silver side up.
The insulating layer is laid on top.
The strips of film are laid side by side, leaving the shower, the bath and fixed furniture clear.
The electrician connects each room to its thermostat.
The floor covering is laid straight away: wood flooring or click vinyl, directly on the film; tiles, on a mat or a dry screed.
We bring the floor up to temperature and go over it with the thermal camera, room by room, before showing you the settings.

The course of a 30 m² room, hour by hour, is on the home page.

The times the manufacturer states

Job	Time
The heating alone	about 75 m² a day, with two people
One to two rooms, floor covering included	one day
A bathroom of 8 to 12 m², mat and tiles included	one day if the floor is flat, plus the setting of the adhesive
An apartment, new floor included	one to two days; in Frankfurt, an apartment of around a hundred square metres was fitted out in one working day
An added storey of 80 m²	a day and a half
A cellar: heating, then wood flooring	two days
A new 220 m² house	four days

These are the manufacturer’s times and jobs, in Germany. It does not state the size of the team for each. For yours, ask for the time along with the quote.

What you prepare

The room, empty. A new floor is being laid in it.
The floor covering. It must be approved for underfloor heating by its manufacturer: it says so on its data sheet. The rules for each floor covering are on the fitting without screed page.
The electricity. Before the job, the electrician checks the protection for each room at the consumer unit.

After

There is no bleeding and no annual service. Under floating wood flooring or vinyl, no gradual heating-up either: you set the thermostats, and that is all. According to the manufacturer, only the version under a cement screed needs one, with the agreement of the screed’s manufacturer. What the manufacturer guarantees is on the warranty and certifications page.

Frequently asked questions

Your questions on this subject.

How long for one room?

According to the manufacturer, one to two rooms a day, floor covering included; a team of two lays about 75 m² of heating a day.

Do we have to move out?

No. We proceed room by room, with no channels to cut and no screed to pour: the manufacturer speaks of dust-free fitting, during which the other rooms stay lived in. The room being worked on, however, must be empty.

Who connects the heating?

An electrician. Each heating circuit has its own line and its own protection at the consumer unit, to the standard of the country. At commissioning, the electrician measures the insulation resistance and tests each circuit.

When can we walk on it?

Straight away with wood flooring or click vinyl: there is no glue and no drying time. With tiles, after the adhesive's usual setting time.

What if my floor is not flat?

Beyond a deviation of 2 mm over one metre, a levelling compound is needed before fitting. It is one more step, with its drying time.
