Heating the hall is an item that is paid for every winter for the next thirty years. And the crucial decision about it will be made before most investors realize it — at the moment when the floor is being made.
Why does it heat differently in the hall than in the house?
The hall has a huge volume and a high ceiling. Warm air rises — and it's coldest where you work.
Systems that heat the air (gas heaters, hot air units) therefore work against physics: most of the heat is under the roof, where no one needs it. In a twelve-meter hall, this means that you will heat cubicles that you will never use.
How floor heating works in the hall
Underfloor heating heats the work area. The heat radiates from the bottom up and the temperature difference between the floor and the ceiling is significantly smaller.
Practical implications:
- Heat is where people and technology are
- The system works with a lower water temperature, so it combines well with a heat pump
- There is no air flow, so dust is not raised — which is essential in paint shops, assemblies and the food industry
- There are no suspended units to obstruct the crane or lighting
Where underfloor heating has limits
It's not a one-size-fits-all solution.
- It reacts slowly. The hall cannot be heated in an hour. This is usually a disadvantage for operations with irregular use.
- High shelves on the heating surface will shade part of the output.
- Frequent opening of large doors means heat loss regardless of the system.
- It cannot be added later. And that is the essential thing.
It is decided during concreting, not after approval
Underfloor heating is part of the composition of the floor. There must be thermal insulation under the concrete slab, pipes will come into the slab, and this changes the thickness and the process of concreting.
It is not possible to add to the finished hall — you would have to demolish the floor.
Therefore, it is decided at the stage when the composition of the floor is decided: underlying concrete, waterproofing layer, thermal insulation, supporting plate. If the heating is not included, there is no insulation under the slab — and without it, the heating would heat the ground.
Where we built it
We have floor heating in our own premises in Uherčice and in the production and storage hall in Mikulov. In both cases, the composition of the floor was designed from the beginning with him — the insulation under the slab, the distribution lines and the thickness of the concrete.
Take a look at our campus in Uherčice and the hall in Mikulov.
What about as an investor
Whatever you decide, tell the building contractor at the beginning. It is not a detail to be solved, it is an input parameter of the floor.
We do not supply the heating, but we do supply the floors — and we design the composition according to what will be in the hall.
Non-binding inquiry — we'll go over what your operation needs.
