Can electrical thermography be carried out in a swimming pool plant room or leisure centre?

Yes. Swimming pool plant rooms and leisure centre switch rooms can be surveyed live while the centre stays open. The boards feeding pool pumps, filtration, dosing, air handling, heating and lighting are imaged with covers opened by the site’s electrician. The warm, humid air needs some care with the camera and the readings, but it does not stop the survey.

What gets imaged in a leisure centre

The main LV switchboard and distribution boards
Motor control panels and starters for pool circulation pumps and filtration
Supplies to chemical dosing and water treatment control panels
Air handling unit and pool hall dehumidification panels
Boiler, heat pump and calorifier control panels
Lighting distribution for the pool hall, sports halls and car park

Gym equipment supplies, sauna and steam room boards, and kitchen or café distribution can be added to the same visit if they are on the asset list.

Why the plant room environment needs care

Pool plant rooms are warm and damp, and chemical stores have their own access rules. None of this stops thermography, but it changes how the survey is run:

Condensation. A camera brought in from a cold van can mist over. It is given time to settle to the room before imaging starts.
Warm surroundings. Pipework, heat exchangers and pump bodies run warm by design and can reflect into shiny panel surfaces. Readings are taken on electrical connections and compared like for like, phase against phase.
Bare metal. Lugs and busbar reflect heat from elsewhere. Readings are taken on suitable surfaces and any limitation is noted.
Chemical areas. Dosing and chemical stores are entered only under the site’s rules and with the PPE it specifies.

Timing the visit

Thermography needs equipment carrying its normal load. Pool circulation pumps usually run around the clock, but air handling, lighting and heating loads are highest when the centre is busy. A survey during opening hours, planned with the duty manager, gives the most representative readings. Plant rooms and switch rooms are back of house, so customers are not affected. See what load a survey needs.

As everywhere, covers are opened by the site’s authorised electrician and nothing is switched off. See who opens the panels.

Across a portfolio of centres

Leisure operators and local authority estates often run several centres. A programme with one asset list, one report format and surveys timed under load makes year-on-year comparison fair. See thermography across a multi-site FM portfolio.

Measuring under real load is the rule everywhere we work. On a London data centre build, commissioning thermography by our team found 16 busbar sections reading above 80 °C under test load, the highest 103.5 °C at a tap-off unit, each located and imaged before handover.

Ti inspects and reports. Any finding is investigated and put right by the site’s electrical team or contractor.

Frequently asked questions

Does the pool need to close for the survey?

No. The survey happens back of house with everything running.

Can outdoor plant and car park lighting be included?

Yes. Outdoor equipment can be surveyed in the same visit, with the weather noted. See outdoor equipment in UK weather.

How often should a leisure centre be surveyed?

Many operators and their insurers work to an annual electrical thermography survey. The right interval depends on the site, its age and its insurer’s requirements.
