Northern Container House with Underfloor Heating

Container houses with underfloor heating in northern regions have achieved widespread adoption, especially in cold areas or during winter seasons. Details are as follows:

I. Prevalence
In cold northern regions (such as Harbin and Inner Mongolia) or in low-temperature winter scenarios, underfloor heating in container houses has been implemented on a large scale. Compared to traditional commercial residences, container houses, with their modular structures and rapid construction advantages, have taken the lead in achieving comprehensive underfloor heating coverage, becoming the mainstream heating solution for temporary or long-term living scenarios.

II. Installation and Design Features
The main body of a container house is made of steel, requiring targeted modifications for underfloor heating installation:

1. Insulation Layer Installation: A 2-3 cm thick graphene XPS extruded insulation board (temperature-resistant from -20℃ to 75℃) is laid on the ground base. This locks in heat, reduces energy consumption, isolates underground moisture, and prevents steel corrosion.
2. Reflective Film and Flooring: Above the insulation board, a propylene cloth reflective film is covered to minimize downward heat loss. On top of the reflective film, interlocking flooring is laid to uniformly reflect heat into the room, enhancing heating efficiency.

III. Advantages

1. Space-saving: The underfloor heating system is hidden beneath the flooring, eliminating the need to occupy wall or floor space, suitable for the compact layout of container houses.
2. High Comfort Level: Heat is evenly emitted from the floor, providing a gentler absorption for the human body, avoiding the dryness and indoor temperature differences associated with air conditioning heating, especially suitable for long-term residence by the elderly and children.
3. Energy-saving and Electricity-efficient: The graphene XPS insulation board uses electric heating, saving about 30% energy compared to traditional boiler-based underfloor heating; combined with comprehensive insulation design, overall energy consumption is lower than that of traditional air conditioning.
4. Longevity Matching: The underfloor heating system is designed with a lifespan exceeding 50 years, far surpassing the 15-20 year usage cycle of container houses, allowing for long-term maintenance-free operation after a single installation.

IV. Application Scenarios
It has been widely used in overseas mobile residences, outdoor homestays, construction site project departments, temporary dormitories, herdsmen's transitional housing, scenic area特色民宿 (special homestays), and emergency disaster relief shelters.

V. Usage Precautions

1. Before use, check the operational status of the underfloor heating facilities to ensure no electrical leakage or heating abnormalities.
2. Maintain moderate ventilation during use to prevent internal moisture accumulation leading to steel corrosion.
3. Use professional tools for cleaning to avoid damaging the insulation layer or reflective film.
4. Immediately turn off the underfloor heating in case of a power outage to prevent equipment overheating and potential safety hazards.
