A significant element of your heating supply system is its installation. During planning, in addition to proper insulation to avoid heat loss, you need to select your pipes carefully. There are options such as steel, copper, plastic and soft steel.

Piping material

Steel piping

• less expensive, but more subject to corrosion
• for installation in floors and walls, corrosion protection required
• difficult to work

Copper piping

• more expensive than steel, but more corrosion resistant
• less heat loss than steel
• well suited for extensions or repairs in heating systems
• easier to work than steel

Plastic piping

• Use only standard inspected piping.
• corrosion resistant and easy to work
• Temperature sensitive as drawback
• Long distances have significant heat transformation.

Mild steel pipes

• more flexible than conventional steel piping
• pipe junctions are simply pressed
• well suited for retrofitting on extension or renovation

Insulating your installation

To avoid heat losses on the way to your radiators, all piping should be well insulated.

• This is especially important on pipe lines through unheated rooms (basement, attic).
• This also applies for expansion vessels, fixtures and water heaters.
• No lines in rooms with a danger of frost.

Recommended insulation:

• Pipes up to 20 mm inside diameter (ID) at least 20 mm
• 20 – 35 mm ID: at least 30 mm
• over 40 mm ID: the pipe diameter
• over 100 mm ID: 100 mm
