Thermor is a leading manufacturer of heating and domestic hot water solutions, recognized for the quality and innovation of its electric water heaters, heaters, and aerothermal systems. At GroupSumi, you will find a wide catalog of Thermor products aimed at efficient installations, providing cutting-edge technology for DHW (domestic hot water) and climate control with a focus on energy savings and reliability.
Thermor has established itself as a leading brand in the HVAC sector, renowned for its expertise and commitment to energy efficiency. As part of Groupe Atlantic, Thermor brings cutting-edge solutions in electric heating and DHW to the Spanish market, tailored to the needs of homes and professional projects. At GroupSumi, we offer the full range of Thermor products so that renovators, installers, and professionals have reliable and efficient equipment to enhance the comfort and performance of their installations.
One of Thermor's hallmarks is its continuous technological innovation. The manufacturer invests in R&D to incorporate the latest technologies into its water heaters and HVAC systems. From smart digital controls to compact designs, each Thermor product leverages technical advancements that optimize performance and simplify installation. This commitment to innovation allows Thermor to offer modern solutions that adapt to industry trends and the growing demands for energy efficiency.
Thermor stands out for its focus on energy efficiency. Its equipment—whether electric water heaters, gas water heaters, or aerothermal heat pumps—is designed to consume less energy without sacrificing performance. For example, many Thermor water heaters feature high-density insulation and precise regulation systems to minimize heat loss. As a result, users achieve energy bill savings and reduce environmental impact. Choosing Thermor means opting for products that comply with efficiency standards (such as superior energy labels) and contribute to more sustainable installations.
The constructive quality of Thermor translates into reliable and durable products, ideal for professionals seeking zero surprises in their projects. The brand uses robust materials (vitrified tanks, anti-corrosion resistors, etc.) and subjects each unit to strict quality controls. Thus, a Thermor electric water heater or a gas heater undergoes rigorous testing before reaching the customer, ensuring optimal long-term operation. This reliability, backed by an official warranty (Thermor offers extended warranties on many of its products), provides peace of mind to both the installer and the end user, reducing incidents and maintenance costs.
Another advantage of Thermor is the wide variety of models and capacities available. The brand offers everything from small 15–30 liter water heaters for limited spaces to large-capacity accumulators (200–300 liters) for high demands, including Thermor condensing boilers for central heating. This diversity makes it easy for professionals to find the exact solution for each project: Thermor has equipment for every need, whether improving domestic DHW, providing hot water to a business, or implementing aerothermal systems in a comprehensive renovation.
The Thermor electric water heaters are among the brand's flagship products. Available in multiple capacities (30, 50, 80, 100, 150 liters, etc.), they efficiently provide domestic hot water in homes and small businesses. They feature advanced technologies such as sheathed ceramic resistors and anti-corrosion systems (O’Pro technology, long-lasting magnesium anodes) that extend their lifespan. Their installation is straightforward, with vertical or horizontal (Slim models) options ideal for limited spaces. A Thermor water heater guarantees reliable hot water supply, reduced maintenance, and excellent insulation to maintain temperature, resulting in daily energy savings.
For those who prefer instant hot water via gas, Thermor offers gas water heaters for both butane/propane and natural gas. The Thermor gas heaters stand out for their automatic ignition and safety systems that control the flame and combustion gases, providing peace of mind to the user. These units deliver hot water instantly and continuously, adapting to different flow rates according to demand. Thermor integrates flame modulation technology into its heaters to maintain the desired temperature with minimal gas consumption. Thus, optimal comfort is achieved in showers and faucets, with the confidence of a brand that prioritizes safety and efficiency in every appliance.
In the realm of domestic heating, Thermor offers compact and efficient gas condensing boilers. These boilers (such as the Thermor Logic range) feature low NOx systems and high modulation, maximizing performance (by harnessing the latent heat of water vapor) and reducing emissions. The Thermor boilers are prepared to meet current regulations and even support more eco-friendly gas mixtures (some models are ready for 20% hydrogen). With suitable power for standard homes, they ensure comfortable heating and combined hot water (combi boilers) with savings of up to 30% compared to traditional boilers. Their reduced size and easy maintenance make them attractive for renovation installations where thermal comfort is sought with the guarantee of a leading manufacturer.
Thermor aerothermal has positioned itself as an innovative solution for heating and DHW, harnessing renewable energy from the air. Thermor offers air-to-water heat pumps with high efficiency, capable of extracting heat from the air even at low outdoor temperatures. These systems stand out for their high COP (coefficient of performance), meaning that for every kW of electricity consumed, they generate several thermal kW. In practice, installing a Thermor heat pump (for example, for domestic hot water) can result in significant savings compared to conventional electric systems or oil boilers. Besides savings, Thermor aerothermal reduces CO₂ emissions and easily integrates into single-family homes, communities, or businesses seeking clean energy. With Thermor, aerothermal energy translates into year-round comfort: heating in winter, optional cooling in summer (in some units), and hot water all the time with a single sustainable system.
At home, Thermor products provide tailored solutions to enhance comfort and efficiency. If you need domestic hot water for showers and faucets, a Thermor electric water heater or gas heater guarantees a constant and safe supply. For residential heating, Thermor condensing boilers or aerothermal systems can efficiently climatize your home, reducing consumption. Their domestic range is designed to integrate easily into apartments and houses, occupying little space and operating quietly. Whether in a bathroom renovation (installing a compact water heater) or a comprehensive heating upgrade, Thermor provides reliable equipment that improves quality of life at home while keeping an eye on energy savings.
In commercial and small business environments (shops, restaurants, offices, boutique hotels, gyms…), Thermor is also a trusted ally. Their large-capacity water accumulators and water heaters can handle high consumption during peak hours, ideal for example for showers in gyms or multiple bathrooms in cafes. The Thermor heaters and boilers for commercial use are designed to withstand daily intensive use, ensuring uninterrupted service to customers and staff. A restaurant, for instance, benefits from a Thermor heater to have instant hot water in the kitchen and bathrooms, while an office efficiently climatizes the space with aerothermal, reducing operational costs. Additionally, Thermor ensures spare parts and technical support, which is crucial for businesses that need to minimize downtime. The brand's reliability and efficiency help companies offer comfort to their end users while keeping expenses under control.
Thermor also meets needs in light industrial applications or technical environments. For large volumes of DHW in warehouses or production processes (e.g., industrial showers, hot water cleaning, etc.), there are Thermor accumulators and modulating solutions that provide high flow rates. Their industrial aerothermal equipment can be integrated into centralized HVAC systems, providing efficiency in warehouse or workshop climatization. In industrial installations where robustness is required, Thermor products respond with industrial-grade materials and superior quality electrical components, prepared for demanding environments. From large electric backup boilers to combined solar thermal systems with accumulation (Thermor even offers solar solutions within the group), the brand provides versatility so that each industrial project has its HVAC and hot water needs covered with guarantees. Thermor understands the complex demands of the industry, and that's why its products ensure reliable performance even at full capacity, day after day.
