Pre-selected for Underfloor Heating Installation
Wet underfloor heating runs warm water at low flow temperatures (35°C–45°C) through continuous oxygen-barrier PEX/PERT pipe loops embedded in your floor screed or low-profile overlay boards. It reduces heating bills by 15%–25% compared to standard radiators while qualifying for SEAI zoning control grants.

Our 4-Step Engineering Process
Floor Build-Up & Heat Loss Survey
We review your architect drawings or extension floor levels and calculate exact pipe spacing and manifold sizing.
Insulation, Edge Strip & Pipe Laying
We install perimeter expansion foam, clip continuous pipe loops, and mount the stainless steel manifold.
Pressure Test & Screed Coordination
We pressurize the manifold to 6 bar prior to liquid screed or tile installation to guarantee 100% leak-free loops.
Manifold Balancing & Smart Zoning
We set individual loop flow meters (L/min), wire actuators to room stats, and hand over your zoned system.
Frequently Asked Questions
Can I install underfloor heating in a kitchen extension while keeping radiators upstairs?
Yes. This is our most popular setup in Dublin homes. We install a dedicated blending manifold with its own pump and smart thermostat for your kitchen/living extension, operating independently as a separate heating zone alongside your existing upstairs radiators.
Can you repair an existing underfloor heating manifold that isn't heating?
Yes. If specific zones of your floor are cold, the issue is usually a failed thermal actuator head, a seized manifold blending valve, a circulation pump fault, or airlocked loops. We service and flush existing UFH manifolds across Dublin.
Does underfloor heating work with wooden floors and tiles?
Absolutely. Porcelain/ceramic tiles offer the highest thermal conductivity, while engineered hardwood and luxury vinyl tile (LVT) perform superbly when paired with a floor temperature sensor limiting surface temperature to 27°C.
