🔍 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.
