Heating Installation in Container Houses

The installation of heating in container houses requires a comprehensive consideration of the house structure, thermal insulation performance, and radiator installation specifications to achieve efficient heating through reasonable selection, scientific layout, and standardized installation.

1. House Structure and Thermal Insulation Treatment

Enhancing the thermal insulation performance of container houses should be a priority, as it is the foundation for the efficient operation of the heating system. The outer layer should use anti-corrosion color-coated steel sheets to reflect sunlight, the middle layer should be filled with more than 50mm of polyurethane foam or rock wool boards to block heat conduction, and the inner layer should be equipped with fire-resistant gypsum boards and moisture-proof membranes, forming a three-layer thermal insulation structure. For example, after using rock wool sandwich color-coated steel sheets at a construction site in the mountainous areas of Guizhou, the indoor temperature was 8-10℃ higher than the outdoor temperature, significantly reducing the heating load. If the house has a double-layer container structure, adjustable sunshades and bottom ventilation slots can be installed to further reduce heat loss.

2. Radiator Selection and Layout

1. Type Selection
   Select the radiator type according to the space height and usage requirements. Standard horizontal or low-profile radiators are suitable for regular rooms. Installing them 15cm above the ground can create good convection. For areas with floor-to-ceiling windows or large bay windows, custom low and long radiators should be used, which are placed close to the ground to maximize the use of heat dissipation space. In cramped spaces, vertical radiators with a height of 1.6m-1.8m can be selected, but it is necessary to ensure that the bottom is at least 10cm above the ground to avoid affecting the convection efficiency.

2. Installation Position
   Follow the principle of "low inlet and high outlet, preferably near the window and avoid obstructions". Priority should be given to installation under the windowsill or on the side of the exterior door, utilizing the thermal barrier effect to block the infiltration of cold air. If the area under the window is blocked by furniture or bay windows, it can be moved to an open space on the adjacent interior wall, but a heat dissipation distance of at least 30cm should be reserved. Avoid installation behind large furniture such as sofas and beds to prevent heat accumulation and a decrease in heat dissipation efficiency.

3. Pipeline Design and Construction Specifications

1. Concealed Pipeline Installation
   Exposed pipelines should be laid along the skirting boards, ceiling corners, or the back of furniture to blend with the wall decoration lines. For example, kitchen pipelines can be hidden inside cabinets, and bathroom pipelines should avoid the positions of shower sprinklers to reduce visual intrusiveness.

2. Air Vent Installation
   Install automatic air vents at the end of the pipelines or at the household inlet to reduce the problem of air blockage caused by air entering the system. If the house has a multi-story structure, air vents should be installed at the top of the manifold to ensure the stable operation of the system.

4. Heat Dissipation Calculation and System Matching

Calculate the heat dissipation based on the room area and heat load requirements. For energy-efficient buildings in northern China, configure according to 60-80W/㎡. For example, a 20㎡ room requires 1200-1600W of heat dissipation. If a gas-fired wall-mounted boiler is used as the heat source, a model that provides both heating and domestic hot water should be selected, and pressure-resistant pipes such as aluminum-plastic pipes should be matched to ensure the airtightness and circulation efficiency of the system.
