Underfloor heating has become increasingly more popular in the UK because of its ability to provide an efficient and uniform heat. The radiant heat provided at floor level creates a large heated surface that dissipates heat evenly into the living space whereas a radiator will produce convection currents that rise to the highest part of the room, meaning that the majority of the heat is lost at ceiling height. This makes underfloor heating more efficient for two main reasons:
- The heat emitted is used more effectively, resulting in less wasted heat
- The heat required to enable this is generally delivered between 35-55oC compared with 65-75oC for radiators which means that the heat source will operate for a shorter amount of time and therefore use less energy.
These energy savings combined with silent running and increased flexibility for room layouts gives a solution that will add real value to a property.
Underfloor heating can work with a variety of heat sources such as gas and oil fired boilers as well as renewable technologies such as air and ground source heat pumps. It can also be installed to almost any floor type from concrete slab, timber joist and as a retro fit system over existing floors.
In addition to the pipe work a key component is the Underfloor Heating manifold and the associated controls. At Emmeti we offer an extensive range of high quality manifolds and controls plus the thermostats, pipes, and accessories required to form a full UFH system solution.
To make understanding easier for you, we have divided our Heating Manifolds into 3 categories: Type 1 (T1) manifolds have no electrical control: Type 2 (T2) manifolds have electrical control facility; Type 3 (T3) integrate flow and temperature management – T3 Controllers accompany T2 Manifolds and T3 UFH manifolds incorporate both in a single unit.
Type 3 (T3) manifolds are for underfloor heating (UFH) systems only. They have a temperature controller and pump, to ensure that the water is at the correct temperature for the underfloor heating circuits, and there is sufficient flow for the greater length of pipe used.
Within this simple explanation of the type are many variations and applications, ranging from stand-alone control groups, like the T3 UFH Controllers, to Floor Control Units which are fully pre-assembled single piece ‘plug and play’ sets, to more complex primary distribution groups, like Firstbox Primary Flow.
Within each range are further variants, reflecting the needs and sizes of underfloor heating systems, from domestic to full commercial applications, with different flow and temperature requirements.
Mixed systems – controlling both wall hung radiators and underfloor heating with manifolds
Emmeti Floor Control Units are designed to work with both a high temperature set of circuits (wall hung radiator circuits running in excess of 60°C) and low temperature circuits (underfloor heating pipe running at temperatures lower than 50°C generally). You can add high temperature circuits to the left hand side of the Floor Mixing Unit, please look at the high temperature T2 rails that are needed, under Floor Control Unit Accessories.

Key Benefits of Underfloor Heating over Traditional Heating
For the Installer
- Provides you with individual isolation of underfloor heating (UFH) loops if required. You are able to isolate parts of the system whilst the rest remains operational, reducing disruption for installation and maintenance.
- Each room is supplied by a continuous loop of flexible pipe, the only connections are at the flow and return on the manifold, eliminating all concealed intermediate joints that could potentially leak
- Ensures that you have good accessibility in the event of a problem – No concealed intermediate joints under floorboards or solid floors limits the points at which a leak could occur to the manifold, significantly reducing the time for fault finding.
For the Main Contractor / Developer
- Gives you peace of mind. Having fewer and easier to access joints reduces the risk of delays and call backs.
- Benefits health and safety on your project and cuts down the amount of hot works on site. Each room is supplied by a continuous loop of flexible pipe, the only connections are at the flow and return on the manifold.
For the Building Occupier / Owner
- Using an UFH system with zone control will enable you to tailor your heating to suit the building activities by allowing rooms to be controlled individually, preventing rooms being heated when unoccupied.
- The water in the UFH system will typically be between 35oC and 55oC compared with 65-75oC found in radiators, providing a more energy efficient solution, saving money on heating bills and CO2 emissions.
- Using an UFH system with continuous loops of pipe promotes the smooth flow of water around the system, minimising running noise and giving you a more comfortable environment.
- The radiant heat produced by UFH provides a very desirable environment by providing a more uniform heating across a room than radiators can.
- Increased flexibility around room layouts by not using radiators will allow you freedom when decorating and more usable space when planning furniture layouts.
- No need to paint radiators or struggle to decorate behind radiators.
- Gives you the flexibility of central and individual control – when maintenance and repair is required, rather than isolating a whole system the service engineer can isolate individual loops without the need to drain the entire system.
- In the unlikely event of a leak, you have the significant advantage of being able to isolate only the loop that has the leak, whilst continuing to use the rest of the system, until remedial work can be arranged.
- Your manifolds can be installed in a convenient location such as a riser or service cupboard for easy access meaning less disruption to the building occupiers and ease of repair/maintenance for engineers and contractors.
For the Specifier
- By specifying this system it allows you to add value to the project with improved comfort for the building occupier.
- Specifying a manifold system will allow your clients you to tailor their heating to suit the building activities by allowing rooms to be controlled individually.
- The water in the UFH system will typically be between 35oC and 55oC compared with 65-75oC found in radiators, providing a more energy efficient solution, saving money on heating bills for the client and reducing CO2 emissions for the environment.
- Innovative concept that will distinguish your project from other designers.
