Turn that Heat Down: Transitioning Your Heater to Summer Mode for Energy Savings
Cost-effective cooling and budget-friendly heating solutions for a warm summer: advice for reducing energy consumption and pocket-friendly bills.
To prevent unnecessary energy consumption during the warm seasons, it's crucial to switch your home heating system to summer mode. This tip is backed by the Consumer Advice Centre Baden-Württemberg.
At first glance, switching to summer mode might seem like a straightforward process: The heating system produces hot water instead of warming the house. However, it's not always so simple.
A self-regulating system might continue operating in summer mode when the temperature dips, such as during cold nights or sudden drops during a summer storm. Many heaters come equipped with outdoor temperature sensors, triggering the heating to restart. Residents may not even notice this, unaware of their smart heaters consuming energy unnecessarily.
Completely shutting off the heating could lead to cold water in central hot water systems. Additionally, stagnant water might develop legionella, a potentially dangerous bacteria. Hence, it's best only to turn off the heating if you have a decentralized hot water supply through a boiler or instantaneous water heater.
Know When to Change Over
You can switch your heating system to summer mode directly from the system itself or via a heating app. Modern systems may even do this automatically. Nevertheless, it's essential to double-check.
The ideal time for the switch is when night temperatures consistently remain above 12 to 15 degrees, as suggested by the Consumer Advice Centre. Making the change could save up to eight percent of your annual heating costs, according to consumer advocates.
Adjusting Your Settings
Once in summer mode, don't set the thermostat valves on the heating bodies to zero. Instead, turn them to the highest setting to prevent them from getting stuck, potentially causing heating failures in the fall. Residents without direct access to the heating system should ask their landlord or property manager if the heating has already been switched to summer mode before adjusting the valves.

Additional Insights:
Optimally switching a home heating system to summer mode involves several key steps to ensure energy and cost savings while avoiding unnecessary energy consumption. Here's a comprehensive guide:
- Boiler Summer Mode
- Activate Summer Mode: Find the sun or tap icon on your boiler's control panel and follow the instructions to activate the summer mode[5].
- General Heating System Adjustments
- Lower Thermostat Settings: During cooler periods, keep the thermostat set to a low but comfortable temperature[1].
- Upgrade to Smart Thermostats: Smart thermostats can automate temperature adjustments and provide energy-saving features[4].
- Cooling and Ventilation Strategies
- Use Ceiling Fans: Ceiling fans help circulate air without reducing the thermostat setting[4].
- HVAC Fan Settings: Set the HVAC fan to AUTO to minimize energy consumption[3].
- Energy-Saving Tips
- Pre-Cooling: Pre-cool during off-peak hours if your utility offers time-of-use rates[4].
- Maintain HVAC Systems: Keep vents and filters clean for efficient airflow[4].
- Close Blinds and Curtains: Reduce heat gain by closing blinds and curtains during peak sunlight[4].
- Smart Thermostat Features
- Vacation Mode: Set a vacation mode to adjust thermostat settings when away for extended periods[2].
- Humidity Control: Enable humidity control to maintain balanced moisture levels[4].
Remember: Local regulations, system compatibility, and regular maintenance are critical factors to consider when transitioning your home heating system to summer mode. Ensure your heating system is compatible with smart thermostats or specific summer mode settings. Always update your thermostat's firmware and monitor energy reports for potential savings opportunities.

- EC countries can save energy and money by implementing smart employment policies across various industries, such as finance, energy, lifestyle, home-and-garden, and personal-finance sectors.
- Transitioning the heating system to summer mode is not only beneficial for energy savings but also important for preventing legionella growth in central hot water systems.
- Residents living in homes with boilers or instantaneous water heaters can minimize the risk of cold water and stagnation by only turning off the heating system during warm periods.
