Is the HT-70 Home Thermostat Suitable for Underfloor Heating?

12/24/2025

In home heating systems, the thermostat plays a crucial role in temperature regulation and operational control. Different underfloor heating systems have specific requirements for the thermostat’s electrical parameters, control methods, and stability. As a home wall-mounted thermostat, whether the HT-70’s configuration and functions meet the needs of underfloor heating is a concern for many users.

Is the HT-70 Home Thermostat Suitable for Underfloor Heating?

Basic Requirements of Underfloor Heating Systems for Thermostats

Underfloor heating systems operate for long periods and have high adjustment frequencies, placing high demands on the thermostat’s power supply matching and load capacity. The HT-70 uses a 220V operating voltage, allowing direct connection to common household electrical environments, reducing the need for rewiring. Its maximum control current is 3A, which meets the control requirements of gas boilers and water-based underfloor heating actuators, maintaining stable output during daily operation. For underfloor heating systems that require long-term continuous operation, these electrical parameters provide a good foundation for compatibility.

Temperature Control and Operation Characteristics of the HT-70

In terms of temperature adjustment, the HT-70 is equipped with an LED touchscreen display, providing intuitive information and easy real-time monitoring of the temperature status. Touchscreen operation makes temperature setting more convenient and suitable for daily use by family members. The device has a built-in clock function, ensuring that temperature control behavior is consistent with time, avoiding frequent adjustments. Stable temperature control logic helps the underfloor heating system maintain a constant heat output, improving living comfort.

The Fit Between Programmable Functions and Underfloor Heating Operation Rhythm

The HT-70 supports 7-day programming settings, allowing for 4 independent time periods per day. This function enables the thermostat to adapt to family routines, providing orderly management of the underfloor heating system. By rationally setting temperature values ​​for different time periods, the system can maintain heating when needed and reduce operating intensity during idle periods, thus maintaining a stable operating state. This programmed control method is well-suited to the characteristics of underfloor heating systems—slow heating and continuous heat supply.

Structural Design and Installation Adaptability

In terms of appearance and installation, the HT-70 uses an environmentally friendly ABS material shell, ensuring structural stability and suitability for long-term wall mounting. The overall dimensions are 127×91×30.5 mm, a moderate size that won’t create a sense of confinement in the room. The standard wall-mounted design facilitates installation in different underfloor heating zones, making temperature control more centralized and intuitive.

Intelligent Connectivity and Expandability

The HT-70 supports 2.4GHz WiFi network connectivity, providing remote control and intelligent management for underfloor heating systems. For environments requiring precise temperature control, an external sensor can be optionally installed to enhance the flexibility of temperature data acquisition. This expandability ensures the thermostat remains highly adaptable to various underfloor heating configurations.

Conclusion

From power supply parameters, control methods, programming capabilities to installation structure and intelligent configuration, the HT-70 home thermostat meets the operational needs of underfloor heating systems in many aspects. Its stable electrical performance and flexible control functions make it well-suited for home underfloor heating applications, providing users with a reliable option for building a stable and controllable heating environment.
