Underfloor Heating Systems
Maincor Germany. Underfloor Heating Engineered as One System.
Complete German underfloor heating: pipework, manifolds, insulation and controls, designed to perform as a single system for 50 years.
Why Maincor
Underfloor heating is only as reliable as its weakest component. The pipe may last 50 years, but if the manifold, the mixing unit, the insulation or the controls are under-specified, the whole system underperforms, and the people who specified it wear the consequences.
Maincor is a German manufacturer of complete underfloor heating systems. Every component is designed to work as part of a single engineered system: PE-RT and PE-Xa pipework, brass and stainless manifolds, thermostatic controls, edge insulation and clip rails. That is the opposite of the mixed-brand approach common in the market, where incompatible components are pieced together and the installer carries the risk.
Key Benefits
- Complete-system engineering: every component designed and tested to work with every other component
- 50-year design life: on Maincor's core pipework range
- Even, comfortable heat distribution: lower flow temperatures, lower running costs, higher occupant comfort
- Compatible with boilers, heat pumps and solar thermal: full flexibility with the rest of our range
- Full technical support from design through commissioning: loop layouts, manifold sizing, flow balancing
Who This Is For
- Architects designing residential and light-commercial projects where comfort is a selling point
- Mechanical engineers sizing low-temperature heating systems
- Developers building to a long-term ownership or warranty standard
- Contractors who need a system that will not come back as a callback
A well-designed underfloor heating system is one of the clearest demonstrations of engineering discipline you will find in residential construction. The pipework is buried. The manifold is hidden. The only thing the end user experiences is even, quiet, efficient warmth, year after year, with no moving parts failing and no maintenance call-outs.
That outcome does not happen by accident. It happens because each loop was sized against the actual heat loss of the room, each manifold was balanced against the others, and each component came from a manufacturer that stands behind the full system.
We supply the complete Maincor range: oxygen-barrier pipework in the sizes you need, pre-assembled manifolds with flow meters and actuators, thermostatic controls (wired and wireless), edge insulation, and clip-rail systems for fast installation on screed or dry constructions.
We pair every system supply with a free design review covering loop layouts, pipe spacing, flow rates and manifold placement, so that what gets installed on site matches what the consultant signed off.
