Frequently asked questions about the Floor heating category
Floor heating — what is it and which systems are available?
Floor heating — is a heating system delivering warmth through the floor surface; types include water-based (PE-RT pipe 16x2.0 or 20x2.0, manifolds and manifold cabinets) and electric (heating cables/mats). Choice depends on your heat source, screed depth and floor covering.
Which pipes are used for water floor heating?
Water floor heating uses PE-RT pipes; common sizes in the range are 16x2.0 and 20x2.0. They are pressure- and temperature-resistant and suitable for embedding in screed and connecting to manifolds.
How is water floor heating installed?
Installation involves laying PE-RT pipes in the floor, fixing them to insulation, connecting to a manifold, and pouring the screed. Manifolds like RV.ROTO KAN N750xx and manifold cabinets sized 335–615x575–580x110 mm are used for tidy installation.
Can water floor heating be placed under a carpet?
Yes, water floor heating can be installed under a carpet provided the carpet has low thermal resistance. Observe maximum surface temperature limits and use a thermostat to control temperature.
What are the advantages and specifics of electric floor heating?
Electric floor heating heats up quickly and requires no boiler; available as cables or mats, suitable for thin screeds and zonal heating. Downsides include generally higher running costs for large heated areas versus water systems.
How to connect a floor heating manifold?
Connect the manifold to the heating system via supply/return pipes and attach PE-RT loops to the manifold outlets. Use manifold cabinets (e.g. 435x575x110 or 485x580x110 mm) and KV 1"SET-P fittings for tidy installation.
How to turn on floor heating and control temperature?
Control is via a programmable thermostat (e.g. HEBER HT-140) or a manifold controller; set the desired room temperature and surface temperature limits for safe operation.
Which manifold cabinets are available and how to pick a size?
Manifold cabinets come for internal and external installation in sizes from 335x575x110 to 615x580x110 mm. Choose based on the number of circuits (2–8) and installation location (in-wall or surface-mounted).
What connection kits exist for manifolds?
There are KV 1"SET-P kits for manifolds (angle and straight, 2 pcs per kit) and standard fittings for PE-RT pipes to ensure leak-proof connections.
Which manifold to choose for 3–6 circuits?
For 3 circuits choose RV.ROTO KAN N75030A; for 5–6 circuits use N75050A or N75060A. Select the model according to the number of outlets and required flow capacity.
