How To Fit Add2Rad
Add2Rad uses ThermaSkirt as emitters: Picture Source - DiscreteHeat Warehouse Tour

A fast, clean, no-disruption installation.
Add2Rad is designed for quick, repeatable installs in occupied homes with minimal disturbance. Follow this guide for consistent, high-quality results.


🧼 Preparation

Before fitting Add2Rad, ensure the radiator surface (skirting) is ready:

  • Clean the radiator surface using a suitable cleaner
  • Ensure the surface is fully dry before applying
  • Remove dust, debris or loose paint
  • Check for sharp edges or contaminants that may affect bonding
  • Confirm access to the radiator and surrounding space

A clean, dry surface is essential for long-term performance.


šŸ›  Step-by-Step Installation

1. Plan the Layout

  • Identify where the Add2Rad strips will be applied
  • Ensure the layout avoids overlaps (unless specified)
  • Consider access, pipe layout, and tricky areas

2. Add the fixings

3. Apply the ThermaSkirt

4. Connect to the tails

5. Refill & Bleed (If System Was Drained)

  • Restore system pressure
  • Bleed radiators as required
  • Check for balanced heating across all emitters

6. Optimise Flow Temperature

  • Use the Flow Temperature Calculator as a baseline
  • Fine-tune based on room comfort and system behaviour
  • Apply heat pump optimisation where relevant

Consistent adhesion and correct flow temperature are the foundations of Add2Rad performance.


šŸ“‹ Handover Checklist

Once installation is complete, ensure the resident understands the basics:

  • Explain what has been done
  • Reassure them that radiators may feel cooler to the touch
  • Provide the Tenant Checklist
  • Provide the Comfort Explainer
  • Confirm they know how to reach support if needed

Clear communication increases resident confidence and reduces call-backs.


For installers working on SHDF or PAS 2035 programmes, record the installation in your commissioning notes and attach this page to your job pack.
