Underfloor Heating used in Melbourne Homes
Hydronic Heating Systems
Projects of hydronic heating screed Melbourne are quite typical in new constructions and luxurious renovations. These systems pump warm water in the floor pipes.
Key characteristics:

- High long term energy performance
- Underfloor Electric Heating

- Bathrooms
- Kitchens
- Apartment renovations
They usually need to have a thinner screed layer that needs close monitoring of temperature during drying.
Types of best screeds to use on heated floors in Melbourne
Liquid / Self-Leveling Screed
In the majority of screeds used in heated floors Melbourne, liquid screed is best practice in that it:
- Flows easily around pipes
- Eliminates air voids

Requirement of Thickness of Underfloor Heating screed.
How Thick a Screed Should be applied over Heating Pipes?
Normal guidelines of underfloor heating screed:
Liquid screed:
- 20-30 mm above pipes
- Traditional screed:
- 50-65 mm total thickness
