As summer arrives, many homeowners wonder what to do with their underfloor heating. While it's generally suggested to keep your underfloor heating system on continuously for optimal performance (see blog post here), this doesn't necessarily apply to the warmer summer months. During this time, you likely won't need the extra heat in your home.
Whether you're new to underfloor heating or considering it for your home, you might be wondering if it's okay to turn off the system during summer. In short, it’s perfectly fine to turn off your underfloor heating in summer, as long as the outside temperature is comfortable for you.
Benefits of Turning Off Underfloor Heating in Summer
Turning off your underfloor heating in summer prevents your home from becoming too warm when the outside temperature is already sufficient. Additionally, it saves you money. While underfloor heating is cost-effective, running it unnecessarily during summer adds to your energy bills. If your rooms get too hot, you might also use fans, which can further increase your energy costs.
How to Turn Off Underfloor Heating in Summer
Typically, underfloor heating is controlled by a thermostat or a smart control system that operates efficiently with minimal manual adjustment. As summer temperatures rise and you decide to turn off your underfloor heating, you’ll need to locate your control unit.
There are two ways to manage your underfloor heating during summer:
1. Switch off your thermostat entirely: This will stop the system from running.
2. Set your controls to ‘Holiday’ mode: This mode allows the system to quickly reactivate when needed. You can set a return date for the system to start running again.
If you choose to switch off your underfloor heating via the thermostat, we recommend turning it back on briefly every couple of weeks for 15-20 minutes (Water systems). This keeps the system calibrated and prevents water from sticking in the pipes.
Other Important Considerations
When it's time to use your underfloor heating again, if water, conduct a few checks to ensure it’s running properly. Inspect the system for any issues, such as leaks, and make sure all components are in good condition. If you notice any problems, consult an expert before proceeding.
Typically, you can switch your thermostat back on, set the desired temperature, and wait a few hours for the system to heat up. We recommend gradually increasing the temperature the first time you use your underfloor heating again to avoid any shock to the system.
Underfloor Heating Not Working After Summer?
Electric underfloor heating systems are generally unaffected by being switched off over the summer. However, water-based systems can occasionally encounter issues after a long period of inactivity. Common problems include malfunctioning thermostats or circulating pump issues. Often, simply resetting the thermostat will resolve the issue; refer to the manufacturer’s user guide for instructions. If the problem lies with the circulating pump, consult an electrician.
Another potential issue is a sticking pin valve, located below the actuator. To check this, remove the actuator and ensure the pin valve can move freely. If the actuator is stuck, use silicone spray, WD40, or long-nose pliers to free the pin.
