What is BTU?
The BTU rate of a radiator is how much heat the radiator will emit, and is there to help you decide if a radiator is the correct size for your room or not. It’s important to know how much heat your room needs in order for your system to work efficiently.
Expected delivery time depends on whether you order a stock radiator or a Made-to-Order radiator. Stock radiators can be delivered within 3-5 working days from placing an order, whereas Made-to-Order models generally take about 3-6 weeks. Small delays can be expected if radiators are being delivered to Scotland and offshore islands.
Please check the detailed delivery details for each product range to see what we have in stock or how long made-to-order deliveries are for that particular model.
