Circoflo Minifolds – How they work


Underfloor heating systems usually use a big manifold that have up to 24 pipes running into it. Because the flows and returns need to be long to get to the manifold, a larger pipe is needed to keep the pressure drop down to a reasonable level. Big bundles of flow and returns can cause local overheating in the floor and should be avoided especially with timber floors and vinyls. But, to complicate things, companies that sell low build-up systems have to also use small diameter pipe, so have to offer different size pipes depending on the floor construction.

CircofloPro’s unique ‘Minifold’ system uses manifolds that are 80% smaller than conventional manifolds and can therefore be located discretely in many more locations, such as wall cavities or cupboards. So, instead of using one big manifold, CircofloPro uses 2or 3 smaller ‘Minifolds’. The flow and returns are therefore much shorter which means12mm pipe can be used for all our systems.The primary pipe connects the CircofloPro ‘Minifolds’ together, similar to a radiator system, and as these primaries don’t have to be in the floor the installation is much easier and avoids any potential overheating in the floor.

CircofloPro’s way of doing underfloor heating makes it easier to buy and install a system.
The range of patented independently tested products we manufacture provide a way of installing underfloor heating in any construction and you’ll know, once installed, it’ll work as expected.


Example of CircofloPro underfloor heating system served by multiple, smaller Minifolds meaning less complicated circuits and good even heat distribution around individual rooms.


Example of other underfloor heating systems where the congestion of pipework associated with a single manifold leads to loss of temperature control and can lead to damage of floor coverings.
