There are certain ingredients that change the way your underfloor heating system will operate. For example, concrete screed floors will behave differently from others and give you better performance.
It's unusual in the UK to see concrete floors on upper levels or on joisted floors. Aluminium spreader plates are often used on first floors and above. These react differently because you're not heating a thermal mass within the floor.
Because of that, you'll need a higher water temperature flowing through those circuits to achieve a reasonable output of heat to your property.
What you don't want to do is mix different floor constructions from the same underfloor heating system manifold. That's because concrete screed floors react differently versus other floor constructions.
The floor covering that you ultimately choose is another element that’ll greatly affect the underfloor heating system’s performance since coverings will have different thermal resistance levels.
By keeping all these various elements of underfloor heating systems in mind, we can help you choose the best system based on your floor type, whether that be screed floors or something else.

great vid, thank you
Hi
Thank you for all you videos, quite helpfull.
Do laminate floors take long to heat up compared to porcelain tiles?
Both floors are concreted floors just the coverings are different.
It is not really the speed at which they heat up, but more tiles will get the heat through better. So, you will get more useful heat/ the system will be more efficient with tiles.
Would it be best to use cement boards or chipboard to top a plate wet UFH system that’s having tiles on top for a 1st floor kitchen? Thanks
It does come down the build height you have and the centres of the pipe. But normally the dry Gypsum system tends to give a higher output. But this may not be a case in all jobs. Call us to go through your job in more detail.
On ground screed floor there will be one manafold located on ground floor. Using heat sprader plate method on 1st floor (timber floor board on joist) do i need another manafold on 1st floor. Can one ground floor manafold supply under floor heating water to both level from same heat source gas boiler. Thanks.
We would always recommend where you have different thermal masses you run different manifolds as HEPs will heat up far quicker than screed but screed runs at a lower temperature.
I’m interested in buying a house in Europe that has cobblestone on the ground floor, that was left in by the builders because it’s from 1887. Only problem is it’s a fairly big open space ground floor (1750sqft) with no walls between the living, dining and kitchen areas. Is it possible to take out the cobblestone and lay floor heating below it? Or do have to lay heating over it and eventually cover the cobblestone with a different type of flooring. We are torn because cobblestone is quite thick so we are unsure about the effectiveness of heat under it. And we will be disappointed if we have to cover a beautiful historical floor from 1887. But if it’s not possible, we understand we have to do it.

No, most screeds and concrete are ok over underfloor heating systems. Just ensure you use a rounded aggregate. and ideally no deeper than 100mm
