  • Optimum performance at a low investment cost

    Optimum performance at a low investment cost

    Thermia Solid Eco is the large-capacity heat pump for those seeking optimum performance and access to the most important functions. It is the perfect solution for less complex commercial buildings that do not need special applications. With an impressive coefficient of performance (COP) of 4.4 (Solid Eco 22 at B0/W35 according to EN14511), Thermia Solid Eco enables you to reduce your energy consumption by up to 75%.

  • Heating capacity

    Thermia Solid Eco is available in output sizes 22, 26, 33 and 42 kW. Cost-effective and economical, Solid Eco is ideal for meeting basic heating and cooling needs at a minimum cost without sacrificing performance.

  • Exceptional hot water production with hot gas technology

    Exceptional hot water production with hot gas technology

    Thermia has developed a unique patent-pending method for producing domestic hot water. At the same time as water is heated for distribution through the building’s heating system, hot water is produced at very high temperature through an extra de-superheater. This means that during the part of the year when the building is heated, you get lots of hot water at a very low cost.

  • Passive and active cooling – year-round comfort

    Passive and active cooling – year-round comfort

    The large areas of glass in many modern buildings are great during the darker months of the year but often lead to overheating in summer. Passive cooling ensures a perfect indoor climate all year round. If necessary, this can be supported with active cooling using the heat pump’s compressor. Both passive and active cooling are far more economical than traditional air-conditioning systems. Solid Eco can provide efficient cooling for your property during the summer.

  • Simple control and ease of use

    Simple control and ease of use

    Solid Eco can control two separate heating systems in the same building at the same time. The intelligent controls make it easy to monitor and control other parts of the system, such as supplementary heat, hot water, cooling, etc. The system can be fine-tuned at any time to suit current needs and conditions, creating optimum efficiency and energy savings.

  • Flexibility


    With Thermia Solid Eco, you get a complete solution to cover basic needs that is perfectly suited for larger buildings, such as schools, churches, mansions, business premises, sports halls etc., which do not need advanced additional functions. There are good opportunities to adapt the heating installation to the prevailing conditions. For example, an old system can be retained in parallel with the new system. With a wide range of accessories, Solid Eco can also provide cooling, heat a pool and work in combination with solar panels or additional heat sources.

  • Thermia Online

    Thermia Online

Incredible, but true…

Incredible, but true…

All Thermia heat pumps fully comply with the Ecodesign Directive

In their stand-alone form, heat pumps receive a maximum A++ rating. As part of integrated systems, they can be rated as high as A+++. In contrast, no heating boiler (oil, gas, bio-mass) is rated higher than A. In some cases, they can be as low as C or D.

All Thermia heat pumps come with the highest possible rating, from A+ up to A+++ depending on the model of heat pump, the choice of heat receiver and the level of system integration.

Thermia customers tell their stories

  • The new home of the Recal Foundation is a stunning, contemporary prefabricated 400 m2 building, which was designed by the famous Spanish architect Joaquín Torres and cost 1 million Euros. The building has attracted local and international attention and recognition as an innovative project, designed and constructed to minimize use of resources and environmental impact.

    State-of-the-art rehabilitation center

    Recal is a private, non-profit healthcare organization. Established in 2001, it boasts a highly professional team of human resource specialists, including doctors, therapists and volunteers. Their shared aim is to help individuals affected by addiction to any substance or behavior to reintegrate into society, including providing family support.

    “We like to take care of our patients, the environment and the resources we receive from our patronage. That is why we chose to install a geothermal system from Thermia, which takes care of our indoor climate all year round at a low cost”, commented José Manuel SAINZ Quintana, general director of the Recal Foundation.
