Enter a few details about the size, construction and use of your building to get an initial estimate of the heating capacity required in kilowatts (kW) and explore the types of commercial heating system that may be suitable.














Your estimated heating load is the approximate amount of heat that needs to be supplied to maintain the required indoor temperature under the conditions entered into the calculator.
For example, if the calculator estimates a heating requirement of 150 kW, this does not necessarily mean that the building simply needs one 150 kW heater. The final heating system may use several heaters, different heating zones or a combination of technologies depending on the building and how it is used.
The right solution can also depend on factors including:
ceiling height and building volum
insulation and building construction
external doors and how frequently they are opened
working zones and occupancy
required indoor temperature
available energy sources
existing heating equipment
whether the entire building or only particular areas need to be heated
The calculator is therefore intended to provide a useful first estimate. A final system design should take account of the building itself and its operational requirements.
Need a more detailed assessment? ABS provides free site surveys throughout the UK, with recommendations based on the building and existing heating system. ABS already promotes free, no-obligation surveys and nationwide site assessment as part of its commercial heating service.







Your estimated heating load is only one part of selecting a commercial heating system.ABS works with a range of technologies, allowing the heating approach to be selected around the building rather than forcing every application into the same solution. ABS currently provides commercial warm-air and radiant heating and works across other heating and cooling technologies.
