With the popularization of household heating, water floor heating has become the mainstream choice with its comfort and energy saving of low-temperature radiation heat dissipation. According to the “China Floor Heating Industry Development Report”, the domestic water floor heating market penetration rate has reached 47% in 2024, but traditional mechanical thermostats cannot achieve time-sharing and zone-based temperature control and lack floor overheating protection, resulting in an average energy waste of 23%. As a national high-tech enterprise with 18 years of experience in geothermal control, we provide a full range of water floor heating thermostat ODM/OEM services, achieving ±0.5℃ precise temperature control and more than 30% energy efficiency improvement through intelligent technology, helping to build a green and energy-saving smart home system.

Product matrix of water floor heating thermostat

Intelligent programmable wired thermostat (HTWF series)

Installation advantages:
Wiring-free design, 2 AA batteries for 12 months (standby power consumption <5mW)
Support wall pasting or base fixing, installation completed in 10 minutes (suitable for old house renovation)
Value-added functions:
Humidity compensation algorithm: automatically adjust the set temperature according to the ambient humidity to avoid air dryness Energy consumption statistics report: generate heating time and energy consumption data by day/week/month to assist energy saving analysis

High-end customized solution (CTWF series)
Professional configuration: Support floor heating mixed water system control: link temperature sensor and electric regulating valve to accurately adjust water supply temperature
Integrated climate compensation function: automatically correct indoor set value according to outdoor temperature, in line with ISO 13790 thermal comfort standard
Industry application:
Commercial places: such as an office building project in Beijing, through 16-way partition control to achieve independent temperature adjustment in different functional areas, air conditioning load reduced by 25%
Special environment: equipped with IP67 waterproof model, suitable for humid scenes such as swimming pools and saunas

ODM/OEM core advantages

Exclusive technical system for floor heating scenes
Dual temperature zone dynamic balance algorithm
The first “air temperature + floor temperature” dual sensor fusion technology (patent number: CN202420135678.9), through the fuzzy PID control algorithm, solves the problem of “slow heating and large overshoot” of traditional floor heating, and the measured temperature fluctuation is ≤±0.3℃
The floor overheating protection threshold can be customized (default 45℃), in line with GB 50736-2012 “Design Code for Heating, Ventilation and Air Conditioning of Civil Buildings”
Climate compensation adaptive technolog
Built-in outdoor temperature acquisition module (optional wireless sensor), automatically adjusts the water supply temperature according to the outdoor temperature and humidity
Floor heating system installation optimization plan
Quick deployment without debugging
Prefabricated 10 common floor heating apartment templates (such as 80㎡ two bedrooms and one living room / 150㎡ duplex), one-click import of temperature curve, improved installation efficiency 60%
Supports “one-to-many” networking mode (1 host controls 8 partitions), saving 50% of wiring costs
Black technology for upgrading old systems
Compatible with mechanical thermostat lines (2-wire transformation solution), intelligent upgrade can be achieved without replacing the manifold
Wireless models support magnetic installation, no need to punch holes on the wall (suitable for renovation of fine-decorated houses)
Energy-saving management throughout the life cycle
Time-sharing and partitioning energy efficiency model
Supports “room-level” precise control (such as low-temperature mode at night in the bedroom, constant temperature mode in the study office), saving 35% energy compared to unified temperature control in the whole house
Linked with solar thermal collection system, giving priority to the use of renewable energy
Energy consumption visualization system
The supporting APP displays the energy consumption proportion and carbon emissions of each partition in real time (unit: kgCO₂/㎡)
Provide annual energy-saving reports, compare benchmark energy consumption data, and assist in applying for green building certification (such as LEED/NGBS)
Material safety guarantee
The sensor probe uses food-grade 316L stainless steel (the part in contact with the floor), which complies with GB 4806.9 Hygiene standards
The shell uses halogen-free flame-retardant materials (flame retardant grade UL94 V-0) to meet the fire protection requirements of the floor heating system
