How Add2Rad Works

Upgrade your heating. Keep your radiators. Skip the mess.

Add2Rad adds slim, efficient skirting-level emitters to your existing radiator system — giving you the heat output you need for heat pumps at 35–45°C.

🔍 The Problem With Radiators (And Why It’s Stopping Heat Pumps)

“Most UK radiators are 30–50% too small for heat pumps.”
— Energy Systems Catapult, 2023

Typical UK homes were built for boilers running at 70°C.
Heat pumps run best around 35–50°C. Big difference — but you don’t have to replace every radiator to make it work.


🛠️ The Add2Rad Method: 3 Simple Steps

1️⃣ Keep Your Radiators

Retain existing radiators and pipework. No need for redecorating, refitting, or relocation.

2️⃣ Add Skirting-Level Emitters

Add2Rad skirting sections extend surface area — adding up to 90W of heat per metre.

3️⃣ Hit Low Flow Temperatures

Reduce system temperature, improve efficiency, and deliver comfort without complaint.
