With the arrival of spring, heating systems are progressively switched off, also due to seasonal regulations that generally require the end of the heating period around mid-April.
However, this does not necessarily coincide with truly stable weather conditions. In May, especially during the evening and early morning hours, many homes can still feel cold, damp or uncomfortable. Temperature fluctuations remain significant, and rainy or particularly humid days can further increase the feeling of indoor discomfort.
It is precisely during this phase that thermoregulation becomes especially important: not to continuously increase the temperature, but to better manage comfort, humidity and the thermal inertia of indoor environments.
For more than a century, IMIT has been developing solutions dedicated to temperature regulation in both residential and industrial applications, with devices designed to improve comfort and energy efficiency.
Why homes can still feel cold in spring
During mid-seasons, indoor comfort depends on several factors at the same time. Outdoor temperatures may be mild during the day but drop rapidly in the evening; in addition, walls, floors and rooms with limited sun exposure tend to accumulate humidity and cool down more easily, increasing the risk of condensation and mold formation.
Even well-insulated buildings are not immune to this phenomenon. In some cases, high thermal insulation can actually reduce air exchange and increase the perception of indoor humidity.
The result is a very common situation: heating systems switched off, but indoor spaces still unable to maintain stable comfort conditions.
Comfort is not only about temperature
When it comes to indoor wellbeing, perceived temperature often matters more than the actual measured temperature.
A room at 20°C may still feel uncomfortable if humidity levels are high or if walls and surfaces remain cold. On the other hand, stable and gradual regulation can improve comfort without significantly increasing energy consumption.
For this reason, during spring and autumn it becomes important to avoid continuous temperature fluctuations and manage the system more precisely, especially in homes equipped with independent systems, fan-coils or heat pumps still operating during springtime.
Thermostats and programmable thermostats: more flexible control
During transitional seasons, system management requires greater flexibility compared to winter operation.
If heating needs to be activated, programmable thermostats allow the system to adapt to actual daily needs, avoiding unnecessary operation and maintaining a more stable temperature during critical moments of the day, such as early morning or evening hours.
Programmable systems also make it possible to differentiate time slots and automatically reduce system operation during milder hours.
Some devices integrate advanced control logics, such as the TPI (Time Proportional Integral) system, designed to exploit the thermal inertia of the environment and limit temperature fluctuations. Several IMIT climate control solutions integrate this type of management system.
Fan-coils and hybrid systems: the advantage of dynamic regulation
In newer buildings or mixed heating/cooling systems, spring often requires even more dynamic management.
Fan-coil systems, for example, can react quickly to climate variations and are particularly suitable for transitional seasons. In these cases, dedicated regulators allow more precise control of room temperature, ventilation speed and heating/cooling modes, while also helping reduce humidity when used with dehumidification functions.
IMIT develops dedicated fan-coil regulators designed to optimise both comfort and system efficiency.
The seasonal shutdown of heating systems does not always coincide with the end of home comfort needs. Mid-seasons remain one of the most delicate periods to manage from a thermal perspective, especially in the presence of high humidity and strong temperature fluctuations between day and night.
In this context, when needed, thermoregulation becomes an essential tool to maintain more balanced indoor environments, reduce energy waste and improve indoor wellbeing, even when traditional heating systems are used only partially or intermittently.
