At dexdari, directed by Kate OHara, we provide high-fidelity thermal engineering solutions for residential and commercial properties across the Dublin 6W region. Operating from 50 Westfield Rd, Harold’s Cross, our technical focus is the design and implementation of radiant floor heating systems that maximize the thermodynamic efficiency of the building envelope. By transitioning from high-temperature convection to low-temperature radiant heat, we ensure a consistent vertical temperature profile that aligns with the requirements of Part L of the Irish Building Regulations. Our services encompass the entire mechanical lifecycle, from initial hydraulic circuit design to final system balancing and pressure verification.

Circuit Architecture and System Classification We categorize our installations based on the structural requirements of the Harold’s Cross property and the primary heat source. Our technical team evaluates the substrate to determine the optimal delivery method:

• Hydronic High-Mass Systems: Designed for new builds, utilizing multilayer oxygen-barrier pipes (PERT-AL-PERT) embedded within liquid screeds. This creates a thermal storage block that operates with high efficiency alongside modern air-to-water heat pumps.
• Low-Profile Retrofit Solutions: Engineered for Harold’s Cross renovations where floor datum heights are restricted. We utilize slim-bore hydronic pipes or ultra-thin electric radiant mats that integrate directly into the adhesive layer without requiring significant structural modification.

Hydraulic Balancing and Manifold Integration The heart of a dexdari installation is the manifold assembly. We utilize professional-grade manifolds equipped with individual flow meters for every circuit. This allows our technicians to perform precise hydraulic balancing, ensuring that every room reaches its target set-point simultaneously, regardless of the pipe length or distance from the heat source. By managing the flow rates at the manifold, we eliminate the energy waste associated with “short-circuiting” and ensure that the circulation pump operates at its peak efficiency.

Structural Preparation and Thermal Insulation A critical technical variable in underfloor heating is the mitigation of downward heat loss. At dexdari (VAT: IE3750668CH), we prioritize the installation of high-density floor insulation boards that meet or exceed SEAI standards.

1. Substrate Audit: We perform a moisture and levelness check of the subfloor before any mechanical layout begins.
2. Expansion Management: We install perimeter expansion strips to decouple the heated floor mass from the structural walls, preventing mechanical stress and cracking during thermal cycles.
3. Vapor Barriers: Heavy-duty membranes are utilized to protect the insulation and maintain the integrity of the screed during the curing process.

Commissioning and Operational Transparency Our work at 50 Westfield Rd is not complete until the system has undergone a rigorous pressure test at six bar for twenty-four hours to verify the integrity of all joints. We provide our clients in Dublin 6W with a comprehensive technical handover pack, including a circuit map and smart-control calibration guides. By integrating intelligent thermostats with independent zone control, we allow for the precise management of thermal loads, ensuring that your home remains comfortable and cost-effective through the Irish winter.
