About Our Systems

Underfloor Heating Specialists in Dublin and Leinster

Underfloor heating manifolds under pressure test
We have installed underfloor heating in Áras an Uachtaráin, in 350 apartments across South Dublin covering roughly 16,000 square metres, and in large domestic homes, working alongside some of the biggest mechanical contractors in the state.
Design, supply and installation for new builds and retrofits, domestic or commercial, at any size. We also design and supply to your own plumber or builder: send us floor plans as a PDF or CAD drawing, or call into the showroom with them.

Why Choose Underfloor Heating

Benefits of Underfloor Heating

Comfort

Radiant heat, like standing in sunlight. It rises evenly from the whole floor, so you get warm feet and no draughts at floor level.

Health & Safety

No hot and cold spots, so no draughts moving dust and dust mites around the room. Nothing hot on the wall for a child to fall against.

Economy

Costs a little more to install than radiators and less to run. Typically 15% to 25% off the heating bill.

Heat Pump Compatible

Heat pumps work best at low flow temperatures, which is exactly what underfloor wants. The pairing also draws on the €2,000 heating upgrade component of the heat pump grant.

Control

A thermostat per zone or room, set to the temperature that room actually needs rather than one setting for the whole house.

Floor Coverings

Tile and stone heat quickest. Most timber floors work, solid or floating. Carpet depends on the tog.

Maintenance & Support

Servicing & Repairs

Underfloor heating needs servicing like any mechanical system. We look for early signs of failure so it keeps running efficiently, and we can diagnose most underfloor faults.
