Retrofitting underfloor heating - affordable, quick and easy

Enjoy cozy warmth and save energy costs? Are you thinking about retrofitting underfloor heating? Whether it's a new build, old building or commercial building: efficient underfloor heating saves money - and can be retrofitted by a specialist company at a reasonable price and with little effort!

Retrofitting underfloor heating: how it used to work

Just a few years ago, it was expensive and time-consuming to retrofit underfloor heating: Underfloor heating was either installed over existing screed or the screed was completely removed before installation. In the first case, you had to live with installation heights of up to 10 cm, depending on the material, at the expense of the room height. The installation height in the area of staircases also proved to be problematic - and not a good idea for retrofitting only selected rooms. The second, less tempting alternative: completely removing the old screed in order to then integrate the heating into the new structure - time-consuming and expensive, not to mention dirty and noisy! A solution that you should only choose if you are planning a complete renovation of your home.

Milling underfloor heating? A clean and cost-effective solution

All that is history: Innovative processes allow quick, clean retrofitting of near-surface underfloor heating systems - with a low flow temperature and maximum efficiency. How does that work? How do you install a new heating system when the screed is in the way? Quite simply, with a method that has been tried and tested since the 1990s: Underfloor heating can also be retrofitted under wooden floors and floorboards in old buildings during renovation work. We simply mill grooves (or slots) for the heating pipes into the existing screed! As a specialist screed company, we bring the milling machine and equipment with us. The requirement is a screed that conforms to standards, smooth and hardened, with a minimum height of around 30 mm. The heating pipes must also meet quality requirements - oxygen diffusion-tight and corrosion-resistant. In order to mill screed cleanly, we use special equipment - powerful machines with extractors that immediately swallow up the dust during milling. This means that the pipes for the underfloor heating can be installed directly and the floor covering laid without any set-up or drying times. Retrofitting your rooms with underfloor heating only takes a few hours. Can this also be done in the bathroom? Of course - the tiles can be laid immediately after the underfloor heating has been installed.

Laying underfloor heating wet - on tacker board

Alternatively, you can have your underfloor heating installed on staple plates. In this case, we lay the heating wet. The tacker system works with a special mounting plate to hold the pipes. Made of insulating material that can be walked on because it is pressure-resistant, the tacker plate also provides thermal and impact sound insulation. In addition to tacker plates made of plastic, there are also ecological solutions, e.g. made of mineral wool - depending on the traffic load and construction height of the floor in appropriate qualities. Additional insulation can also make sense if the thermal transfer resistance is insufficient. And this should be done before any staple boards are laid: As a solid specialist company, we first assess on site whether additional thermal insulation is required. Good heating specialists plan an underfloor heating system professionally - and in such a way that every detail fits the project and building individually, right down to the installation method in meander or spiral form. We can already promise you one thing: The costs are manageable at well under 100 euros per square meter!

Laying staple boards: how the specialist company does it

Compressed to save space, we generously roll out the tacker panels on the surface in order to lay them on a level, swept-clean substrate. A special edge insulation strip helps to acoustically isolate the floor from the rest of the building. Now we lay a foil apron made of tear-resistant fabric foil over the laid tacker boards - this keeps them in place. To make it easier for our installers to cut the insulation to size and lay the heating pipes more precisely, a grid is printed on the tacker plates by the manufacturer. Why are they called that? Because the heating pipes are firmly anchored to the thermal and impact sound insulation using plastic tacker needles. This DIN-approved tacker system is particularly easy to install and cost-efficient; all components are matched to each other. Dimpled sheets are also an option for wet installation: here, the installer presses the cables firmly into the dimples for a secure hold. Once the heating pipes have been laid, we connect them to the underfloor heating manifold. And carry out the pressure test: is everything really tight?

Screed from a master craftsman - for the perfect floor!

The time has come - we apply the heating screed. It surrounds the pipes and embeds your underfloor heating in the screed. Did you know? It's not the floor covering that makes the perfect floor, it's the screed as the substrate! At, we have the necessary know-how. Because a suitable screed

- evenly distributes pressure on the insulation underneath
- levels out unevenness in the subfloor
- raises a floor to the desired height
- creates a level base for all types of floor covering
- provides thermal insulation and reduces impact sound
- can also be used or walked on without a floor covering

Screed is our profession - for over 25 years. Which is why we follow the technological changes in our hobbyhorse with fascination. With our ambition to be at the cutting edge of innovation, we are only satisfied with our work when you are too.

Of course, we do not use cement for underfloor heating ...

... but anhydrite screeds such as calcium sulphate. After all, cement is harder to heat up - and only a handful of underfloor heating systems are suitable for dry screeds. Thanks to its liquid consistency, flowing screed is self-levelling and therefore does not need to be smoothed, compacted or actively spread. It also impresses as a heating screed with very good thermal conductivity, easy processing and a short drying time. In short, flowing screed provides an excellent coating for heating pipes with ideal load distribution - a stable construction. Your new underfloor heating can go into operation!

Your new one - only as good as your underfloor heating manifold!

Now the heat just needs to be distributed evenly across all the underfloor heating circuits: With a heating distributor, each room, each office floor has its own heating circuit(s), individually adjustable as required. In turn, each floor of your building can have its own underfloor heating distributor. But you can also equip only selected rooms, such as the bathroom and living room, with underfloor heating. With several heating circuits, you can operate different system temperatures - and also assign a remote control and separate time program to each heating circuit. Modern underfloor heating systems can also be controlled via a cell phone app. Underfloor heating manifolds control the flow rate and balancing separately for each heating circuit. Up to twelve heating circuits can be connected together in one heating circuit manifold - ready to guarantee even heat distribution everywhere.

How do you finance the retrofitting?

Competently installed, underfloor heating creates a comfortable indoor climate, increases the value of your property and can noticeably reduce your energy costs. Reason enough to make the switch now - from conventional radiators to underfloor heating. But how can you finance the installation? If you meet certain conditions, state subsidies are available for this renovation. However, there is one thing you should not do: Saving money at the wrong end by having underfloor heating systems installed by unqualified tradesmen. Connection errors etc. take their revenge - you will pay for it later. Retrofitting underfloor heating by a specialist company is a safe investment, whether in private housing or public buildings, production facilities or private homes.
