The size of the boiler you need will depend on the size of your building and hot water needs.
A general rule of thumb is to allow 50–60 watts of heat output per square meter or 5–6 watts per square foot. To put this into an example, if your building is 10,000 square feet, we would recommend that your boiler will need to produce 500,000 British Thermal Units (BTUs).
