Many people use wood stoves for their beautiful flames and powerful heating capabilities. However, it seems that as time goes on, some people find the seasonal tasks of gathering and preparing firewood, which they once enjoyed in their youth, becoming increasingly burdensome. Air conditioners and electric heaters are far from providing the warmth that penetrates to the core of the body, and with the relentless rise in electricity prices, there are concerns. While kerosene stoves and gas fan heaters may provide warmth, they take away the joy of watching the flames... but here’s some good news for you. You may be able to connect a pellet stove exhaust pipe using the existing chimney of your wood stove. With a pellet stove, you don’t have to give up the warmth from the infrared heat directly from the flames or its powerful heating capabilities. Additionally, pellet fuel can be reliably purchased at nearby home centers or stove retailers, freeing you from the hassle of making your own fuel. Please feel free to consult with us. *For more details, please refer to the PDF document or feel free to contact us.*

The increase in energy demand due to economic recovery from the spread of the novel coronavirus, irregular weather and disasters, as well as the Russian invasion of Ukraine since February 2022, has disrupted the balance between energy demand and supply, leading to high energy prices. In Japan, over 70% of the power generation mix is from thermal power, and the fuel for this is largely dependent on imports from overseas. In the related links, we provide detailed information about the increasingly popular "pellet stoves" and "pellets." Our company began handling pellet stoves in 2011, initially selling only a few units per year while receiving technical guidance from domestic manufacturers. However, from 2014, we started importing and selling stoves from the Italian company EDILKAMIN, and from 2018, we began importing stoves from the Belgian company Stuv. *For more details, please refer to the PDF materials or feel free to contact us.

When objects burn around us, it is necessary for three conditions—combustible materials, oxygen, and a heat source—to be met, which is commonly referred to as the "three elements of combustion." On the other hand, the combustion pot of a "pellet stove" has slits and ventilation holes to take in fresh air, but if these become clogged with ash or clinker, combustion cannot be sustained due to lack of oxygen, causing the flame to gradually turn dark red and eventually leading to a misfire. In the related links, we provide detailed information about stoves from CS THERMOS. CS THERMOS stoves are equipped with an eco multi-burner that crushes and discharges combustion ash at regular intervals, allowing for long continuous operation without opening the front door of the stove. In the future, we plan to introduce a sealed (shield) model compatible with high airtightness and high insulation homes to the Japanese market. It is expected to arrive in Japan as early as early April. *For more details, please refer to the PDF materials or feel free to contact us.

In late autumn 2021, we received an inquiry from a customer in Ojiya City, Niigata Prefecture, stating, "We would like to implement snow melting on the road surface." As a second proposal, we re-planned the idea of bending the "H" shaped large roof from the middle on the road side, modifying the large roof and the small roof, which previously required manual snow removal, for snow melting. The snow falling from the large roof to the back area remains unchanged from before, and since the area for adding thermal energy is small, we can now avoid worrying about snow removal from the small roof and the subsequent snow disposal on the road. [Challenges] - The customer is a company owner, and it is quite difficult to approach snow removal in perfect physical and mental condition. - Snow falling from the large roof on the road side accumulates on the small roof directly below, requiring manual snow removal again. *For more details, please refer to the PDF document or feel free to contact us.*

Recently, I tried burning all-wood pellets made mainly from cedar wood in a stove, and I observed the formation of a noticeable "clinker (fused ash)," so I would like to share this experience. The pellets I tested this time are classified as "all-wood pellets," and compared to "white pellets," they look quite different even before combustion. When I burned these pellets in the EDILKAMIN POINT, which we handle, for a full day (about 9 hours), a large mass of ash remained in the combustion pot, resembling biscuits. In the case of home pellet stoves, since they are heating appliances that you interact with daily, I think it is best to try several types of pellet fuel while paying attention to factors like "availability" and "heat output," and choose the one that feels most suitable for you. *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) in a detached house. The hot water concealed method can be applied to both new and existing homes. In this case, the old roof metal was removed, and snow melting panels were installed. After 25 to 30 years of construction, the house itself tends to deteriorate, and family structures change, leading to a situation where there are no longer any snow removal helpers, making snow melting a more common choice. In mountainous areas, heavy snowfall can occur in a short time, with snowfall rates of 3 to 5 cm per hour, so a powerful kerosene boiler is used as the heat source in combination. 【Case Overview】 ■ Tokamachi City, Niigata Prefecture ■ Kerosene Boiler ■ 119 m² *For more details, please refer to the PDF materials or feel free to contact us.

We would like to introduce a case study of roof snow melting (hot water type, exposed method) for detached houses. For existing houses with new finishing materials or stainless steel sheet metal on the roof, the exposed method is suitable if you only wish to melt snow in certain areas. We manufacture fixed brackets to match the working range of the finishing materials and arrange stainless steel piping, which has excellent long-term durability, or SGP piping, which has superior rigidity. Compared to concealed methods, the atmospheric radiation from the surface of the snow melting pipes is greater, so it is necessary to increase the temperature of the circulating liquid, which tends to result in about a 10% increase in fuel consumption. 【Case Overview】 ■ Tokamachi City, Niigata Prefecture ■ Kerosene boiler ■ 134m2 *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, concealed method) in a detached house. For small roof areas, combining PTC characteristic electric heaters with snow melting panels and using a concealed installation method can result in relatively low construction costs. PTC heaters have the characteristic of high output at low temperatures, with output becoming milder as the temperature increases, allowing for both fuel efficiency and overheating prevention. However, it is important to note that the breaker capacity needs to be about twice the rated output, and in areas with heavy snowfall in a short period, it may not keep up. 【Case Overview】 ■ Nagaoka City, Niigata Prefecture ■ PTC Heater ■ 21m² *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) 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 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.

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.

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.

Every year, multiple accidents during snow removal are reported, and it is necessary to ensure sufficient safety by conducting the work with multiple people and to remain vigilant to prevent accidents. However, in heavy snowfall areas where regular snow removal is necessary, the aging population means that some households are unable to perform snow removal at all, and there are often cases where busy work schedules lead to snow accumulation that becomes unmanageable after just a short period. In cases where snow remains, workers often go up onto roofs to manually remove the leftover snow. Our snow melting system is called "non-water-spraying snow melting equipment," which directly applies thermal energy generated by boilers, heat pumps, and electric heaters to roofs and road surfaces to melt the snow. *For more details, please download the PDF or feel free to contact us.

"I want to install a roof snow melting system because my work is busy." We often receive such inquiries. However, if we try to address this with electric heater-type snow melting systems, it requires a significant amount of energy, about 300 to 350W per square meter. This means that even for a house of around 30 tsubo (approximately 100 square meters), the equipment would need to be around 30kW. In years with heavy snowfall as well as light snowfall, the basic fees will be a burden based on the equipment capacity. Our snow melting system is called a "non-water-spraying snow melting system," which directly applies heat energy generated by boilers, heat pumps, or electric heaters to the roof or road surface to melt the snow. The output can be easily adjusted through temperature control, and in years with light snowfall, fuel costs can be significantly reduced, making hot water systems suitable for heavy snowfall areas. *For more details, please download the PDF or feel free to contact us.*

We would like to introduce our "Snow Melting for Tile Roofs (Tile Roofing / Concealed Copper Pipe System)." For snow melting on tile roofs, many systems involve exposed piping on the surface of the tiles, primarily using rubber hoses or SUS flexible pipes arranged along the surface of the tiles. However, our installation allows for a "concealed" method where copper pipes are laid beneath the tiles. In our snow melting system for tile roofs, we raise the tile battens and place thin copper pipes between the sheathing board and the tiles. However, due to the increased resistance in the piping, we cannot extend the piping length for each circuit, which tends to result in a higher number of branches. [Features] - Raise the tile battens and place thin copper pipes between the sheathing board and the tiles. - Due to the increased resistance in the piping, we cannot extend the piping length for each circuit, leading to a tendency for a higher number of branches. *For more details, please refer to the PDF document or feel free to contact us.

In the past, polybutene pipes were used for road surface snow melting, but now high-density cross-linked polyethylene pipes (PEX), which are lightweight, flexible, and rich in workability and durability, have become mainstream. In the event of a leak in road surface snow melting, it becomes difficult to identify the leak location and repair the piping when embedded in the pavement. To minimize this risk as much as possible, we use a continuous piping system with one circuit per roll and ensure that there are no joints in the embedded sections. [Features] ■ Generally, we plan for embedding within concrete pavement slabs. ■ When embedding within asphalt pavement slabs, we use high-temperature resistant aluminum polyethylene composite pipes. ■ There are cases where construction is carried out while cooling with cold water. *For more details, please refer to the PDF materials or feel free to contact us.

We would like to introduce the points and examples of our roof snow melting system. In cases where the central part of the roof has melted snow but snow remains at the eaves and gable ends, workers have to climb onto the roof to manually remove the leftover snow. To prevent such situations, we install piping all the way to the outer edges, and particularly increase the piping density at the eaves. 【Key Points (Partial)】 ■ Areas where snow tends to remain, such as eaves and valleys, are designed with increased piping density to enhance heat dissipation. ■ In the case of horizontal tile roofing, vertical piping is generally used, while horizontal piping is employed only at the eaves to prevent snow cornices. ■ We investigate the usage of the floor directly beneath the roof and design increased piping density for rooms directly above the north side, which tend to have lower usage rates. *For more details, please refer to the PDF document or feel free to contact us.

Road surface snow melting primarily aims to melt snow in areas such as residential entrances and in front of garages. Our company predominantly uses hot water piping for snow melting, but in cases of smaller areas, such as all-electric homes, we may select embedded electric heaters. Additionally, depending on the budget and the usage conditions of the building, we may also choose to install electric heater mats when it is difficult to dismantle existing pavement slabs. Due to its nature, road surface snow melting cannot retain accumulated snow like roof snow melting, which often leads to longer operating times.
