Thermia Mega Eco

The Thermia Mega Eco inverter-controlled commercial ground-source heat pump is the ideal choice for all types of commercial buildings with advanced heating and cooling systems and very high demands on both energy-efficiency and functionality. This makes it the perfect solution for large commercial and public buildings needing an advanced control system and special applications. With an impressive seasonal coefficient of performance (SCOP) of 5.44 (Mega Eco XL at B0/W35, according to EN14825, cold climate) Thermia Mega enables you to reduce your energy consumption by up to 80%.

At Thermia, we are committed to healthier lifestyles and reducing our environmental footprint. That’s why Mega Eco is the first commercial ground source heat pump on the market with the more climate-friendly refrigerant R454B and the lowest GWP* value – 466. Moreover, thanks to its unique design, it requires a smaller volume of refrigerant than other heat pumps, resulting in a very low C0₂ equivalent.

The R454B refrigerant represents innovation in every way. It is an excellent heat transfer medium that leads to greater energy efficiency and cost-effectiveness.

* GWP stands for Global Warming Potential and is today the most accurate measure for the assessment of environmental impact level.

Thermia Mega Eco is available in five sizes:

• Mega Eco XL 21 – 85 kW
• Mega Eco L 14 – 58 kW
• Mega Eco M 11 – 44 kW
• Mega Eco S-E 10 – 33 kW (+ 5/10/15 kW)
• Mega Eco S 10 – 33 kW
  

It is possible to cascade-connect up to sixteen machines to achieve up to 1350 kW. Cascade-connected pumps start one after the other depending on energy need, thus ensuring minimum energy consumption regardless of the output. With a unique feature called Energy Source Control, heating capacity is adapted to the currently available energy source (boreholes or exhaust air).

Installing a Thermia Mega Eco pays off in a short time thanks to large energy savings for both heating and cooling. With a wide range of accessories, Mega Eco can also heat a pool and work in combination with solar panels or additional heat sources.

Thermia has developed “hot gas” a unique method of producing domestic hot water. At the same time as water is being 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.

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. Mega Eco can provide efficient cooling for your property during the summer.

Simultaneous heating and cooling enables you to reduce operating costs even more. To achieve this, multiple heat pumps are connected in parallel between hot and cold buffer tanks. The hot tanks connect to the heating zones and the cold tanks to the cooling zones. Mega Eco then simply exchanges hot for cold, depending on the needs of the building. For example, as a hotel conference room is cooled down, the excess heat removed is re-used to produce hot water for the swimming pool or SPA.

The controller coordinates and controls the heating system. Thermia heat pumps work with complete precision to give your home the best possible indoor climate at the lowest possible cost. Our controller is very easy to use.

New features:

• Menu and algorithms developed by Thermia
• New color touchscreen
• User friendly, intuitive menu with icons and info-graphics
• Full overview of temperatures from refrigerant circuit
• Compressor “envelope” visualization
• Heat curve with 7-point adjustment
• Plug-and-play software update via USB slot
• Ready for building management systems (BMS) via Modbus

The new controller in the Mega Eco heat pump boasts a color touchscreen display and user-friendly icons that are easy to understand.

Mega Eco features Thermia Online, a function that allows remote control and monitoring using a smartphone or computer. Our online system provides installers with comprehensive diagnostics data and also enables them to respond promptly to notifications or access a live feed on system performance. Online control and monitoring optimizes energy efficiency for property owners with buildings in different locations.

The built-in online function is part of the intelligent control system. The Thermia Online app is available for both Android and iPhone.

The advanced control system of this commercial heat pump constantly monitors all functions, providing you with a reassuring overview. Mega Eco can communicate with other control systems (building management systems) via Modbus. It can also be controlled and monitored via a management system that gathers information on alarms, ventilation and other systems in the same building.

By continuously adjusting the heat pump’s output to current demand, inverter technology enables the heat pump to supply 100% of your energy requirements. This in turn means that the user does not have to pay for any auxiliary heating. Inverters can combine large heating demand in winter and smaller hot water demand during summer, without the need for large hot water tanks. In addition, inverter technology is more friendly for power grid soft start and lower starting current.

Thermia heat pumps are designed, tested and manufactured in one of the harshest climates in Europe – Sweden. Swedish winters can be extreme. February is usually the coldest month, with temperatures dropping as low as -30°C or even lower in the north and heating is essential from September to May.

All our products are designed and built from top-quality European components with authorized Thermia consultancy for system design. Thermia Mega Eco is built on over 40 years of experience in developing and supplying heat pumps.
