Underfloor heating C2Energy

Underfloor Heating

C2 Energy provides "Wet" underfloor heating systems. Underfloor is sometimes referred to as " Radiant heating". Today's Underfloor heating systems are cleaner and require little to no maintenance for the end-user. Underfloor Heating has become increasingly popular in Ireland over the past 10 to 15 years. It provides high levels of comfort, contributes to a healthy living environment and is incredibly efficient if installed correctly thereby reducing the use of non-replenishing natural resources.

Solar Thermal Systems

Our Solar Thermal panel system uses the power of the sun and turns it into heat for solar hot water, solar space heating and solar pool heaters. A Solar Panel (collector), either a flat panel or evacuated tube, is mounted on a roof, wall or the ground in an area exposed to the sun.


The power of the sun heats up the fluid circulating through the collector. The fluid is then transported, through insulated pipes, to a heat exchanger coil inside a storage tank (Hot Water Cylinder). The heat is absorbed into the water in the tank and the cooled fluid is transported back to the collector to begin the process over again. This cycle continues until the hot water need in the domestic hot water cylinder is satisfied or the collector is no longer able to heat the fluid sufficiently (nighttime).

Biomass Boilers Northern Ireland

Viessmann has introduced the Vitoligno 300-C to Ireland in November 2015 with the first one installed and operational. The compact Vitoligno 300-C pellet boiler is an efficient solution for new and existing buildings with low energy consumption. With an output range of 12kW, 18Kw, 24Kw, 32Kw, 40Kw and 48Kw this pellet boiler modulates down to 1:3 and features low energy consumption. Installation and maintenance of the Vitoligno 300-C is extremely easy and makes heating with pellets very comfortable with automatic feed and cleaning features.

Underfloor Heating pipe

Is a pipe constructed using aluminium sandwiched between two layers of Cross-linked Polyethylene - Polyethylene raised temperature "PE-RT". It is designed to operate with temperatures up to 95­ºC with a short-term increase to a maximum of 110ºC. This makes the "Pert-al-pert" pipe suitable for hot and cold-water distribution throughout your home. Of all the pipes available, C2Energy Ltd is proud to be able to supply the two best-in-class pipes in the range. PERT is a five-layer pipe, the aluminium pipe casing is laser-welded.  This forms a homogeneous aluminium layer. The core of the Pert-al-Pert pipe is a thick-walled Polyethylene basic pipe.
