Hydronic Screed Heating – R1 Rated

R1 Screed Heating is a method of hydronic floor heating that is installed on top of the structural slab within a concrete screed. It is ideal for a project with a screed being poured for a specific polished concrete finish, or if a much more responsive system is required. Much the same as in-slab heating, in screed heating, is ideal for large open spaces and heats the entire home with two large benefits. That it heats the home faster and is a more efficient option.

What is Hydronic Screed Heating?

Hydronic screed heating is an upgraded version of slab heating.

Screed heating is when the pipes that carry the heated water are laid within our insulated pipe positioning board on top of the slab. The pipes and board are then covered with a 70mm thick concrete screed.

In Screed Heating reacts much faster than in slab heating due to the screed being far less mass than a slab. The R1 insulation board also ensures that no heat is lost down below the screed making it much more efficient.

How is In Screed Hydronic Floor Heating Installed?

In screed hydronic heating is installed on top of the structural slab and includes a pipe positioning insulation board. Like in slab heating all walls and cabinetry need to be marked out prior to installation and the concrete pour should happen the day after installation to prevent any form of damage by weather or people.

Important Numbers:

  • 20mm – Board Thickness
  • 18mm – Positioning Knob Height
  • 16mm – Pipe Thickness
  • 70mm – Screed Thickness on Top of Board
  • 90mm – Additional Height on top of Structural Slab
  • 32MPa – Minimum Concrete Strength
  • SL82 – Recommended Mesh in Screed

Framing should have a triple base plate or 2 extra noggin’s on the baseplate to act as formwork for the additional depth of our boards and the concrete that is poured on top which is a total of .

We then place our pipe positioning boards in between all framework and cabinetry markings on top of the slab in the rooms that are to be heated. We then run our pipework through the boards in circuits of 100m in length covering 20 sqm each.

How long does it take to heat up?

It takes around 6 hours for in screed hydronic heating to warm your home. Because the response time is quite fast when compared to slab heating, you can manage your temperature and energy use more efficiently by lowering temperatures over night, or turning the system off completely if you are going away for a short time. A more affordable floor heating option is in slab heating.

What does In Screed Heating Cost?

When budgeting for screed heating there are two aspects to take into consideration.

The Hydronic Heating Component – by us dPP Hydronics
The Concrete & Finishing Component – by a Concretor and Polishing Professional

A rough guide when calculating the cost of the hydronic heating, the concrete and the polishing is $210 per square metre for a modest finish. Options such as the quality of the concrete and the level of finishing to the concrete surface will increase this square meter rate. There are also minimum job figures as well as other considerations.
