What equipment types can I size?

FCU, DX indoor/outdoor, MVHR, AHU, fans, pumps, heat pumps, radiators, electric heaters, fan convectors, chillers and boilers — each with type-specific design inputs and unit-aware outputs.

Is this a replacement for manufacturer selection software?

No. This produces a first-pass selection brief (duty, flows, ESP, power). Final selection requires manufacturer software, acoustic data, and project-specific constraints.

Where do catalog matches come from?

Curated manufacturer entries verified from manufacturer literature. Always confirm current duty and dimensions on the manufacturer product page before specifying.

Building services equipment selection sizing

Size FCU, DX, MVHR, AHU, fans, pumps, heat pumps, radiators, chillers and boilers from design duties with correct units. Instant equipment selection brief for UK MEP.

What this calculator does

Equipment finder helps UK building services engineers with size fcu, dx, mvhr, ahu, fans, pumps, heat pumps, radiators, chillers and boilers — selection brief with units, plus curated catalog matches. The calculation follows Manufacturer data methods used in everyday MEP design — enter your project inputs below for a first-pass result.

Whether you searched for "equipment finder", "equipment finder calculator", or "how to equipment finder", this page gives you a working tool plus the context to use it on a real job.

When to use it

Use this for early-stage sizing and sanity checks on UK building services work. It is not a substitute for issued calculations — verify against the project specification, drawings, and relevant standard before sign-off.

How to use it

1. Fill in the inputs for your scenario (defaults are starting points only). 2. Click Calculate — results include the method and assumptions where applicable. 3. Verify against the project specification and relevant standard before issuing.

Tips

Defaults are indicative — replace with project-specific values from the architect, structural, or MEP spec.
For issued calculations, save results in your BuildFlo project and attach to the calculation folder.
