Stelrad offer a basic and advanced heat loss programme to help calculate the BTU (British Thermal Unit) requirement, needed to heat your room or project.
Both the basic and advanced heat loss calculator programmes are online platforms. You can login to the advanced programme from anywhere in order to access your account. All your previous project will be stored and can be easily duplicated, saving you time and hassle.
The Stelrad basic heat loss calculator makes various assumptions based on your choices and may not take into account all factors relating to your particular requirements. If you require a more detailed calculation please use the advanced version of the programme at starsapp.co.uk. We accept no liability for any errors resulting from the estimates given using our BTU calculator. Calculations are based on Delta-T 50°C (Δ-T50°C) in accordance with BS EN 442. Your use of the Stelrad basic heat loss calculator is subject to these terms and conditions.
The advanced heat loss programme is also known as STARS (Stelrad’s Technically Advanced Radiator System), this is an online heat loss programme designed by Stelrad for anyone who needs to calculate heat loss for a room or need a radiator size calculator, so as to choose the correct heating requirements.
Use this heat loss programme for a comprehensive calculation which you can enter all your parameters that affect heat loss in your room.
The advanced heat loss calculator programme takes the user through a simple step-by-step process of inputting key information for any room type including the wall, floor and ceiling dimensions, choosing wall materials and door and window types. It enables instantaneous heat loss calculations using the unique room planner where you can simply drag the walls and calculate the output figure in real time.
Once the room specification is completed the heat loss programme suggests a selection of appropriate radiators from Stelrad’s product portfolio. A product can then be selected to replace heat lost from the room. STARS will also calculate the heating requirements for an entire building and suggest appropriate boilers (combi or heat only).
A radiator schedule and boiler specification can then be printed or saved.
