Underfloor hearing is a very efficient solution for heating the home. Compared to a traditional radiator system – an underfloor heating system can save 25% or more on your annual energy costs. When costing for renovation and new-build projects,  it is important to look at the bigger picture, a radiator system may be cheaper initially however saving over 25% a year on energy costs -  it won't take many years to recuperate the initial outlay for an underfloor heating system. Added to that , the property will be more attractive for resale.

Under floor heating is not only about saving on energy cost and improving your carbon footprint. It provides comfort throughout the home distributing heat at low temperature. A correctly designed system will cover the entire footprint of the property excluding bathroom and kitchen appliances etc.. It is important to lay the right amount of tube for the demand of the room and the correct flow temperature to achieve the required room temperature.

The main components and materials for an underfloor heating project are : - 

• CAD drawings. We provide professional drawings that are easy to follow. They provide all the information necessary to easily install the underfloor heating system. That includes the position of the manifold (s), the pipe layout and spacing, pipe lengths required for each circuit and zone, room temperature requirements, flow temperature, heat losses and positioning of thermostats.
• Insulation - extruded polystyrene is recommended. On renovation projects the thicker the better, For new-builds - building regulations in force must be followed. Perimeter insulation is also required, it is important that it covers all the exterior walls, this allows the screed to expand and contract.
• Mounting rails and pipe clips/staples Mounting rails are attached to the insulation , they help the pipes to be installed in straight lines and make it easier to position the pipe The pipes should be clipped sufficiently in between each rail and on every bend to prevent the pipe from lifting when the screed is laid.     
• Pipe – The heating pipework is used to distribute the heat from the heat source to dissipate within the slab A quality pipe is essential. The size needs to be sufficient to achieve the correct flow rate. The pipe also needs to be durable to prevent kinking when shaping bends. We recommend for domestic installations  16mm PEX-Xb polyethylene. It is not recommended to join pipe especially within the slab.
• Manifold - the manifold is used to distribute warm water from the heat source or storage to heating circuits and zones. For maximum efficiency the manifold should be equipped with actuator valves that can close individual zones as the room reaches the target temperature and flow meters that can be adjusted to achieve the correct flow rate.
• Circulating pump - the correct size pump is important to achieve the correct flow rate to all the individual circuits at the required flow rate. All pumps installed should now be ERP ready in line with current regulations.
• Mixer valve - mixer valves control the flow temperature from the heat source to the under floor heating. This is achieved by mixing the flow temperature from the heat source with the return from the underfloor heating system to achieve the required flow temperature for the underfloor heating system. This can be done manually or automatically. For new builds and highly insulated properties , advanced automatic mixing valves that take into account the outside air temperature are recommended.
• Combimix control units are an option to combine a circulating pump, mixer valve, thermometers, pressure gauge, filling valve and automatic air vent. The combimix fits directly onto the manifold.
• Room thermostats - room thermostats regulate the temperature of individual rooms. Basically when the room reaches the set temperature , the circuits are closed. Most modern room thermostats also feature a night time set back and weekend options.
• Actuator valves - actuator valves are installed onto the manifold circuit valves – the actuator valves open and close the circuit valves when the command is received from the room thermostat.
• Wiring center - the wiring center is the nerve centre of the heating controls. Wiring centres are designed to make the wiring of a system easier. It provides central switching and is therefore ideally situated close to the manifold. A 230v is provided to switch the relevant zone actuators, underfloor heating pump and valve.
