## Heat is a process, not just a heater

A credible service requires more than placing hot-air equipment in a room. Furniture, walls, floor edges and densely packed items warm at different rates. The treatment has to manage those differences so the planned exposure reaches difficult locations without damaging the property.

Technicians use heater capacity, air movers, placement and temperature probes to control the process. Ask whether the sensors record more than the easy-to-heat room air and how the team responds when a location warms slowly.

## Define the treatment boundary

Is the service treating one room, connected rooms, the whole flat or selected contents? What inspection evidence supports that boundary? Heat cannot address a harbourage outside the treated area merely because equipment is powerful inside it.

In flats, shared walls and movement between rooms make the inspection boundary particularly important. That does not mean every neighbouring home is affected; it means the provider should explain the risk assessment.

## Preparation should preserve the plan

Preparation may include removing aerosols, pressurised containers, heat-sensitive medicines, plants, waxes or specific electronics. The provider should give a written item list. Moving every bag to an untreated room can create a refuge, so confirm whether an item should stay, be sealed, be separately treated or be removed.

Reduce dense piles so air can circulate, but do not dismantle or discard furniture unless instructed. Make access to skirting, frames and cupboards practical. Tell the provider about sprinklers, alarms, vulnerable finishes or areas that cannot be heated normally.

## What happens on the day

After setup, the team should monitor the property rather than leave equipment operating without control. Air movers redistribute heat; probes check selected points; belongings may be repositioned where the plan requires it. Access rules apply throughout the work.

## After heat treatment

Cooling, re-entry, laundry and monitoring instructions should be provided. Ask whether a residual product was used and, if so, what it was and where it was applied. Do not immediately deep-clean a residual treatment area without understanding the effect on the programme.

Heat does not prevent a future introduction from luggage, furniture or an untreated connected location. The follow-up should distinguish treatment failure from a new introduction rather than relying on a broad promise.
