We would like to introduce a case study of roof snow melting (electric heater type, exposed method) for detached houses. After more than 25 years since construction, we received a consultation about wanting to take measures to prevent snow eaves from falling due to the neighboring house being built. Since the request was to only take measures on the north side of the large roof, we installed a lightweight heater net afterwards, successfully preventing the occurrence of snow eaves. With a capacity of about 300W/m2, we combined it with a type of controller that allows easy adjustment of the "remaining snow processing operation time" in case of any leftover melting snow, which has been very useful.

We would like to introduce a case study of snow melting on road surfaces (hot water type, buried method) in detached houses. With the new construction of a store and residence, we planned snow measures for the customer parking lot. In the case of sole proprietors, if valuable time is taken away by snow removal, customer service may not be adequately provided, which seems to lead to many implementations in clinics, dental offices, tax accountant offices, beauty salons, and osteopathic clinics. In this case, due to the large area of nearly 100m2 and the preferential gas rate for snow melting in Ojiya City, we delivered a hot water system using a wall-mounted gas heat source.

We would like to introduce a case where the area in front of the garage and the external parking space were melted using electric heaters due to the construction of a new residential building. This area experienced heavy snowfall, exceeding 100 cm per day at times. However, since it was determined that installing a boiler was not preferable for an all-electric home, an electric system was adopted. The area exceeds 30 m², and considering the potential future burden of electricity costs and the possibility of a decrease in the number of parking spaces due to changes in family composition, the circuit configuration allows for the area in front of the garage to be turned on independently. 【Case Overview】 ■ Tsunan Town, Niigata Prefecture ■ Heater Unit ■ 34 m² *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case study of snow melting on the road surface (electric heater type, exposed method) in a detached house. In a residence of an elderly woman living alone, the approach from the entrance to the front road was about 8 meters long and was originally equipped with a water-based snow melting system. However, due to the slope, it did not melt uniformly. One winter, after she slipped and fractured her bone on the frozen entrance, she consulted us with the request for "something that melts reliably, not just water." We installed a snow melting mat that could be applied only in necessary areas, ensuring her safety.

Here is a case study of floor heating installation at a nursery in Kariwa Village, Niigata Prefecture. Initially, it utilized electric storage floor heating powered by night-time electricity, but in response to changes in energy policy, it was upgraded to hot water floor heating using a ground source heat pump (HP) with a high coefficient of performance (COP). To maximize the high COP characteristic of the HP heat source, the outlet water temperature was set relatively low at around 45°C. However, to ensure effective heating performance, the installation combined highly conductive heating panels with copper pipes, which also have high thermal conductivity, achieving a surface temperature of 28°C. 【Case Overview】 ■ Kariwa Village, Niigata Prefecture ■ GeoHP ■ 864m2 *For more details, please refer to the PDF document or feel free to contact us.

Here is a case study of delivering panel heaters to a lodging facility. When renovating a ski resort inn for foreign guests, the owner requested, "We want to achieve quiet and high-quality radiant heating throughout the entire building." At the time of consultation, construction had already progressed to the floor installation stage, so the plan was to install hot water panel heaters in each room. We delivered 27 panel heaters, particularly focusing on areas with higher heating loads, such as under and beside windows, as well as a fan convector in the drying room, which the owner was very pleased with. 【Case Overview】 ■ Nozawa Onsen Village, Nagano Prefecture ■ Kerosene boiler ■ 27 panel heaters and others *For more details, please refer to the PDF document or feel free to contact us.

Here are some examples of the installation of floor heating (water-based, embedded method). During a large-scale renovation of a traditional farmhouse, we received a request to maintain its old charm while also achieving comfort. We proposed floor heating by embedding cross-linked polyethylene pipes in the concrete floor and combining them with an oil boiler as the heat source. To reduce the heating load, we laid insulation material on the upper sub-base before heating, and meticulously sealed the gaps around the foundation before finishing the installation. 【Project Overview】 ■ Iiyama City, Nagano Prefecture ■ Oil Boiler ■ 47m2 *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case study of roof snow melting (hot water type, concealed method) installation. We received a consultation from a quiet hot spring inn that is typically hit by heavy snowfall of over 2 meters each year, stating, "The roof snow melting system installed over a decade ago is not effective, and despite consuming a lot of fuel, it melts poorly. We would like some assistance." The heat source unit that was replaced a few years ago was continued to be used, while almost all other components including panels, copper pipes, supply pipes, and controls were replaced. As a result, the entire roof began to melt evenly, leading to a resolution of the issue.

We would like to introduce a case study of roof snow melting (hot water type, concealed method) installation. In the construction of a highly designed complex cultural facility, the design was progressing with a structural strength capable of withstanding 6 meters of snow. However, due to concerns about the impact of snow falling from the roof perimeter onto the surrounding area, it was decided to incorporate roof snow melting urgently. The concrete slab was box-cut only at the perimeter to install the snow melting panels, and considering the long piping length and evaporation of hot water due to induced lightning, aluminum composite three-layer pipes were adopted instead of copper pipes. 【Case Overview】 ■ Tokamachi City, Niigata Prefecture ■ Wall-mounted gas boiler ■ 477 m² *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce examples of snow melting systems for roofs and pavement (hot water type, exposed method, buried method). In the process of rebuilding the office and fuel supply facility, it was necessary to establish a 24-hour system for receiving tank trucks, so we decided to melt the snow on the parking lot pavement and the office and canopy roof. Although it is a newly constructed building, the roof finish was corrugated metal, so we opted for the exposed method using SGP piping. Since the required temperature range for roof snow melting and pavement snow melting differs, we mixed the hot water from both piping systems to optimize the outlet temperature. 【Case Overview】 ■ Tokamachi City, Niigata Prefecture ■ Gas boiler ■ 688m2 *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case study of surface snow melting (hot water type, buried method) at a senior complex facility. In the construction of a multi-purpose facility that includes serviced housing for the elderly, day services, and childcare support, surface snow melting was planned to avoid hindering the parking and stopping of user transport vehicles and to reduce the labor of the facility manager. Due to the difficulty of securing sufficient water volume for large-scale sprinkling of snow melting in a building facing a national highway, and considering that finishing the area from the parking lot to the approach in a dry condition would be more user-friendly, a hot water type snow melting system was adopted.

We would like to introduce examples of roof and pavement snow melting (electric heater type, exposed method) construction in communication facilities. To protect the aluminum alloy housing of an unmanned exchange station from snow load, electric heater mats for preventing snow accumulation were installed around the roof perimeter. Mats were also laid in the vehicle access area and worker pathways, significantly reducing snow removal labor. In unmanned facilities and remote locations, electric heating (either heaters or heat pumps) is more suitable than boiler heat sources, which carry the risk of fuel depletion. 【Case Overview】 ■ Niigata Prefecture, Shibata City ■ Heater Mats ■ 52m2 *For more details, please refer to the PDF document or feel free to contact us.

This is an introduction to a case study of roof snow melting (hot water type, exposed method) at power-related facilities. Following the roof collapse accident at a power plant in 2017, measures to reduce snow load on roofs were adopted at various power-related facilities. In this facility, a combination of conventional sprinkling snow melting systems and manual snow removal was used, but ensuring the ability to sprinkle water on the ground was also prioritized, leading to the selection of an exposed method using high-rigidity SGP piping on the roof. Despite the presence of many existing structures and a complex piping configuration, efforts were made to average the circuit lengths, resulting in improved melting efficiency. 【Case Overview】 ■ Tsunan Town, Niigata Prefecture ■ Kerosene Boiler ■ 477m2 *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case study of roof snow melting (electric heater type, exposed method) installation. When constructing a new radiation therapy building on the grounds of a general hospital, we planned measures against snow eaves that were a concern for the flat roof perimeter. As a countermeasure against scattering due to strong winds, we adhered a special rubber-based adhesive to the parapet cap surface, and on the flat roof surface, we installed it in a linked manner using brackets, creating a string of beads. Since the mat will be installed year-round on the rooftop, we adopted high weather-resistant products and designed it so that future damage can be replaced on a module basis, enhancing the system's robustness. 【Case Overview】 ■ Nagaoka City, Niigata Prefecture ■ Heater mat ■ 77m2 *For more details, please refer to the PDF document or feel free to contact us.

Mr. K from Tokamachi City, Niigata Prefecture, used to be confident in his physical strength and would go sea fishing with heavy loads on his back. However, after experiencing health issues and being hospitalized following a vaccination, he began to be advised by his sons about roof snow melting systems. He researched various companies and came across "Hokuetsu Yusetsu" in his hometown of Tokamachi City. He thought that directly melting the snow on the roof would be a better approach. After using the roof snow melting system for one season, he found that the dangerous work at heights was completely eliminated, and his physical burden was significantly reduced. Previously, he would handle the snow that fell to the ground with a snow removal machine, but now he uses a snow dump to transport the snow to a nearby river to wash it away. As a result, this season he didn't need to use the snow removal machine at all, and his sons are pleased, saying, "Dad, this is really great!" 【Benefits of Implementation】 ■ No more dangerous work at heights ■ Significant reduction in physical burden ■ No need for a snow removal machine *For more details, please refer to the PDF document or feel free to contact us.
