Proud to be a 100% Bulgarian company

Mareli Systems originated in Bulgaria, nestled at the base of three mountains and alongside a rushing river. This environment contributes to the durability and resilience of both our company and our products against harsh weather conditions. Furthermore, as a reputable European manufacturer, we export Mareli Systems products to more than 30 countries globally, consistently ensuring top-notch quality through monitoring systems like ISO and certifications from prestigious inspection agencies.

The Four Elements of Nature in Service of Humanity

The four elements of nature – earth, air, fire, and water – are the essence of all earthly existence. Their balance brings perfectionism, harmony between body and spirit, an unstoppable flow of creative energy, merging with the environment.

Mareli Systems’ philosophy is based exactly on this – to acknowledge and master their power to perfection, using it in service of humanity. As a result, all the heating and hot water technology solutions, developed and implemented by the company, are offered at affordable prices, so that everyone can benefit from their valuable qualities.

Earth

The earth is a symbol of patience, orderliness and practicality, and life-giving energy springs from its bosom. Millions of trees are born thanks to its never-ending cycle, whose benefits humanity has known for centuries. That is why Mareli Systems manufactures a wide range of boilers, stoves and burners using biomass as their fuel in the form of wood or pellets. In this way, heat with a low carbon footprint reaches people’s homes in an environmentally friendly, sustainable and autonomous way.

Air

Air is a symbol of rationality, intelligence and the capacity for excellence. Therefore, using the latest technologies in heating and air conditioning, Mareli Systems produces its own series of heat pumps, extracting heat from the air and transferring it to the comfort of the internal environment. Air circulation also inspires the fan coils series, impressive for its efficiency, flexibility and contemporary design.

Fire

Fire is the element capable of bringing light even in the darkest moments. It is a key element in the Mareli Systems product range, harnessed to warm any home or business process, while giving peace and harmony.

Water

Water is the fluid whose power and energy is embedded in every cell of nature. It plays an important role in Mareli Systems products, carrying heat to where it is most needed. The company’s solutions in the field of hydronic heating systems have been proven over the years and have added value to thousands of customers.

The factory is the heart of our business

The Mareli Systems factory is the heart of our business. That’s why we take care of it, equipping it with machinery and equipment from the world’s leading manufacturers such as the German giant TRUMPF.

But any machine is useless if it does not have a team of knowledgeable and motivated engineers behind it, using the cutting edge technology to achieve our common goals. So, if the factory is the heart of Mareli Systems, then our team is its soul.

Sustainability

Sustainability and environmental protection are the other themes we strongly believe in, which is why our products achieve energy efficiency from A+ to A+++ and our factory produces over 1MW of renewable energy through photovoltaic panels on the roofs.
