When it comes to energy efficiency, starting from scratch with a brand-new system isn’t always necessary.
Even an existing installation, if properly regulated and maintained, can deliver excellent performance in terms of comfort, energy consumption, and durability over time.
Here’s an operational checklist and some practical advice to help you optimize the performance of your heating and cooling system, supported by IMIT solutions.
Checklist for existing homes
Regular maintenance of the system helps prevent inefficiencies and malfunctions, ensuring consistent comfort and energy savings.
- Thermostat positioning: it should be installed about 1.5 meters above the floor, away from drafts, heat sources, and direct sunlight.
- Firmware update: for digital or connected devices (such as Wi-Fi programmable thermostats), updates improve stability and add new energy optimization functions.
- Flow rate and circulator check: make sure water flow rates in the various circuits are balanced to avoid thermal imbalances between zones.
- Cleaning of heat pump filters: dirty filters reduce performance and increase energy consumption.
- Sensor and probe verification: check measurement accuracy and replace any sensors that are no longer reliable.
- Boiler combustion test: should be carried out annually to verify generator efficiency and safety.
Profile management and automatic switching
Proper management of day/night temperature setpoints helps maintain comfort while reducing energy use.
For example, setting 20°C during the day and 17°C at night ensures savings without compromising comfort.
In hybrid systems, it’s useful to establish automatic switching rules between the heat pump and the boiler based on outdoor temperature, ensuring that each generator operates within its optimal efficiency range.
Multi-zone control and balancing
Dividing your home into independent thermal zones allows you to heat only where needed, improving comfort and reducing waste.
- When it’s recommended: homes with multiple floors or distinct usage patterns (day/night zones, offices, rarely used rooms).
- Zone valves and fan-coil controllers: enable independent regulation of each area, managed by dedicated thermostats or programmable thermostats.
- Basic hydraulic balancing: essential for ensuring even heat distribution and optimal system performance.
Smart programming with Wi-Fi thermostats
New-generation Wi-Fi programmable thermostats, such as IMIT Orion Wi-Fi, offer precise and flexible temperature control through advanced features:
- Custom time profiles: adapt temperature based on daily routines and weekly schedules.
- Geolocation and app control: automatically adjust temperature when you’re away from home to avoid unnecessary energy use.
- Smart integration: compatible with home automation systems and remotely manageable in real time.
- Reduction of unnecessary ON/OFF cycles: the TPI (Time Proportional Integral) logic optimizes system activation, maintaining a stable temperature without spikes.
- Anti “comfort overshoot” tips: avoid overly high setpoints that cause overheating and waste energy.
Energy savings
Proper programming and multi-zone management can generate energy savings of up to 15–25%, depending on the system type and usage habits.
It’s advisable to involve a qualified technician for fine-tuning key parameters (climatic curves, sensors, hydraulic balancing, thermostat configuration) to ensure optimal and safe operation.
With the right control tools and advanced devices like IMIT Orion Wi-Fi, even existing systems can become smarter, more efficient, and sustainable — improving comfort while reducing waste every day.
