Let Casa work out your BTU to determine the correct Radiator(s) size to heat your room
BTUs are ‘British Thermal Units’, the unit in which radiator efficiency is measured.
Factors such as the type of room (lounge/dining room, kitchen, bathroom, or bedroom), as well as whether or not it has a north-facing wall, double-glazed windows and patio doors, are used to calculate the required outputs of radiators in order to adequately heat a room.
Use our user friendly BTU Calculator to determine the heat requirements of your room. Simply enter the details in the corresponding fields and we’ll show you how many BTUs you need to ensure your space is always warm, cosy and inviting.
Please note: the calculated figure is a rough guide for the combined heat output of all radiators in your room (larger rooms may require more than one radiator).
Once you've calculated BTU's, use our contact form to provide BTU outputs & receive a quote by selecting Radiators option on the form >>
