About

Our company is a Hungarian family business that has been operating for more than 40 years. Our main activities are 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 the domestic market that meet the requirements and challenges of the modern age.

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

The real opportunity for major change came with the political shift in 1989. The Hungarian gas program created a sudden demand for gas-fired equipment. We began manufacturing our own designed solid and gas boilers. Initially, we produced around 50 self-designed boilers per month, but by the 2000s, this number grew to 10,000 units per year. Production had to adapt to the increased demand, leading to mechanization, an increase in workforce, and expansion of our premises.

After the end of the gas program, solid fuel boilers and equipment re-emerged as alternative heating solutions. Our Celsius boilers can operate with a wide variety of fuels, such as wood, coal, biomass, pellets, oil, and vegetable oil. Our broad product range, from 19 kW to 500 kW, meets all needs, whether for a family home or an industrial facility.

In our developments, we have always adhered to the three principles of our company: safety, efficiency, and comfort. Our wide range and aesthetic appearance aim to satisfy the needs of our customers. As a result, pellet-fired boilers and complete heating system packages were also born.

Over the past four decades, we have weathered numerous economic challenges, always adapting to the demands and needs of the time. This flexibility and commitment have made it possible for the reliability and quality of our products to remain market-leading today.

As a family-run business, every member of our company is dedicated to excellent quality and continuous development. This is why you can be sure that with Celsius products, you can safely and efficiently ensure the warmth of your home.
