About

Our company is a Hungarian family business that has been operating for more than 40 years. Our main activities include the manufacturing of solid fuel (wood, biomass, and pellet) boilers, the distribution of heating systems, and building engineering products. Our goal is to offer outstanding quality and reliable Celsius products to both domestic and international markets, meeting the requirements and challenges of the modern age.

The founder of the company, Ferenc Perlaki, started the business alone in 1982 in a roofless garage, manufacturing solid fuel boilers on a contract basis. Over time, there was significant interest in the high-quality work performed. In addition to the production of wood-fired boilers, he also received orders for the manufacturing of heat exchangers for gas boilers.

The real opportunity for significant change came with the political transformation in 1989. As a result of Hungary’s gas program, there was a sudden high demand for gas-fired equipment. We began manufacturing our own designed solid fuel and gas boilers. Initially, we produced about 50 self-designed boilers per month, and by the 2000s, this number increased to 10,000 units per year. Production had to be adapted to meet the increased demand, leading to the mechanization of production, an increase in workforce, and expansion of our facilities.

Following the decline of the gas program, solid fuel boilers and equipment came back into focus as an alternative heating method. Our Celsius boilers can operate on a variety of fuels, such as wood, coal, biomass, pellet, oil, and vegetable oil. Our wide range of products spans from 19 kW to 500 kW, thus meeting all needs, whether for a family home or an industrial facility.

During our developments, we have always kept our company's three core principles in mind: safety, efficiency, and comfort. We have aimed to meet our customers' needs with a wide selection and aesthetic design. As a result, pellet-fired boilers and complete heating system packages were also created.

Over the past four decades, we have weathered numerous economic challenges, always adapting to the era's needs and challenges. This flexibility and commitment have allowed our products' reliability and quality to remain market-leading today.

Every member of our family-run business is dedicated to excellent quality and continuous development. Therefore, you can be assured that with Celsius products, you can safely and efficiently ensure the warmth of your home.
