The Dexdari Project Protocol

We don’t just “fit pipes”; we engineer environments. Every inquiry at dexdari (VAT: IE3750668CH) follows a structured technical audit to ensure the longevity and efficiency of the installation.

  1. Site Diagnostic: We begin with an assessment of your existing substrate and insulation levels in the Harold’s Cross area to determine the most effective radiant delivery method.
  2. Thermal Mapping: Using site-specific data, we design a custom circuit layout that eliminates cold spots and optimizes the Coefficient of Performance for your primary heat source.
  3. Commissioning & Handover: Upon project completion, we provide a full technical pack including pressure test results and system maps, ensuring you have a permanent record of your thermal assets.

Harold’s Cross Operational Base

Our facility is located in the heart of Dublin 6W, allowing us to provide rapid logistical support and site visits throughout the Leinster region. While we are primarily a field-based engineering firm, our administrative and design operations are conducted from our Harold’s Cross headquarters.

  • Registered Operational Address: 50 Westfield Rd, Harold’s Cross, Dublin 6W, Co. Dublin, D6W K127, Ireland.
  • Logistical Note: Technical site visits must be scheduled in advance to allow for a full review of your building’s mechanical and electrical specifications.

Statutory & Compliance Verification

As a fully registered Irish entity, dexdari provides the transparency required for modern building control and sustainable energy grants. Our VAT registration (IE3750668CH) and adherence to Part L of the Irish Building Regulations ensure that every project we undertake at 50 Westfield Rd and beyond is fully compliant with national safety and efficiency standards. We maintain comprehensive professional indemnity and public liability insurance for all thermal installations and system maintenance works.

At dexdari, we believe that clear communication is the first step toward a perfectly balanced home. We look forward to engineering a thermal solution that combines invisible luxury with laboratory-standard reliability.
