Hydronic In Screed Floor Heating
Are you building or renovating? Heating concrete slabs, or in screed floor heating is a great way to heat a kitchen or large living areas (over 60 m²)!
There are three possible ways to install hydronic underfloor heating: directly in the slab, in the screed or using diffusion plates.
Similar to the in slab installation, the heat produced by the hydronic in screed heating system radiates from the floor upwards into the room and provides a comfortable temperature. Additionally, since the system does not blow dust around like forced air heaters, the application is ideal for allergy sufferers.
A hydronic screed heating system is in essence the upgraded version of slab heating. Compared to an in slab heating installation, the in screed installation will heat up much quicker.
Perfect for polished concrete finish, the in screed installation is highly efficient and the running costs will benefit homeowner’s budgets.
In Screed Heating Installation
For this configuration, the heating pipes are layed on top of the finished slab and requires a minimum of 30mm of concrete cover over the pipes (therefore a minimum screed depth of 50mm). This is ideal for a floor cover such as as polish concrete, marble, stone, slate and all varieties of tiles.
This system is generally faster acting than an in slab heating system. Similar to other systems, it radiates heat from the floor upwards, creating a comfortable, gently heated environment with no draughts, dust or noise.
The heating is controlled using floor or air sensing thermostats that regulate the flow of hot water through the pipe circuits.
We recommend insulation that can be installed on top of the finished slab with the water pipes attached directly to the insulation.
The installer would supply and install the appropriate insulation materials beneath and around the edges to, again, prevent downward heat loss.
