Jaga Low-H20 selected as the most economical radiator

After the Belgian WTCB (Belgian building research institute) and the British BRE, the Dutch KIWA institute also awarded the highest score for Jaga's Low-H2O heat exchanger.

Jaga's Low-H2O radiator has been thoroughly tested over the years by a variety of independent bodies in various countries. The Low-H2O radiator achieves the lowest carbon emission output, using the least amount of energy, time and time again. It will therefore be no surprise that more than 10 million of these radiators with their innovative design have already been installed worldwide. The Jaga Low-H2O radiators have proudly held this prestige for some time now, accompanied with it's 30 year guarantee the Low-H2O radiator provides confidence in being the most reliable solution as well as the most energy-efficient and comfortable heating solution.

9 to 16% energy saving

9 to 16% energy saving

The savings proved by Kiwa will reduce the total characteristic energy consumption of an average home by 36 Megajoule per m2. An average home of 140 m2 will save 141 m3 gas per year, just by opting for Low-H2O radiators!

Lower CO2-emissions

The lower the energy consumption, the lower the CO2--emission. A saving of 141 m3 gas per home means a reduction of 293 kg/year in CO2--emissions. This is quite significant, if you remember that an average car can cover 2000 km with the same CO2-emission!!

Less material use

The fact that a Jaga Low-H2O radiator is lighter and smaller than traditional radiators at the same power, means not as much raw material is cunsumed for production. Low-H2O radiators also have a longer life – they have a 30-year guarantee – and at the end of their life, they can be completely recycled. Nature wins hands down which every way you look at it!

Lower investment

Since Jaga Low-H2O radiators are also efficient at high water temperature, a compact, cost-effective installation can also achieve an acceptable energy consumption. With Jaga Low-H2O radiators, these installations almost always earn the same number of EPC points under Dutch law, as low temperature installations with underfloor heating systems or panel radiators. A smaller investment will bring you the same advantage!

Maximal E-level reduction in EPB-software

The EU directive on the energy performance of buildings EPBD should significantly help to reduce the energy needs of member countries and the extent of their carbon emissions. These directives, always tightened throughout the years, are implemented in all countries: EPB in Belgium and the Netherlands, CEP in France, DGNB in Germany. In many countries, like in the Netherlands (through the Kiwa quality declaration) or in Belgium and France, better energy certificates can be realized with Low-H2O radiators.

The quickest and most adjustable radiator

A small mass heats faster than a large mass. That's a law of nature. Low-H2O radiators hold to 90% less water. Unlike traditional radiators with their heavy steel plates and high-volume water systems, the heat generated by a Low-H2O radiator can be experienced immediately. Not only is the heat generated faster, but the heat can also be stopped many times faster. When the temperature goes up due to sunshine radiating into a room, or from another heat source, the Low-H2O adjusts the heating level very quickly. That results in a constant indoor temperature at the desired level.

The quickest and most adjustable radiator

The Jaga Low-H2O heat exchanger is not made of steel, but of super - fast conducting copper and aluminium, which immediately transfers its heat to the room. The advantage of this excellent conductivity increases as the water temperature falls! The serial matrix irrigation with up to 16 copper tubes and the optimised corrugated shape of the aluminium fins maximises heat transfer from the central heating water to the air. As soon as the thermostatic valve opens, the heat is quickly, evenly and accurately distributed throughout the room.

Ecodesign with 30 year garantuee

Jaga Low-H2O radiators consume less energy. But it is not only during their life that they are more environmentally friendly. Since a Jaga Low-H2O radiator is much lighter and smaller than an equivalent capacity of a steel panel radiator, the raw material requirement in manufacturing is also significantly reduced. Furthermore, Low-H2O radiators last longer, they have a 30-year guarantee, and are also fully recyclable at the end of their life cycle. Compared to other heating systems, the Low-H2O radiator scores remarkably better in LCA measures , which compare the environmental impact of a variety of products.

The Low-H2O technology makes the difference

"There is a clear correlation between the weight of a radiator, its reaction time and its energy efficiency."

The low mass radiator with super fast heat exchangers

A small mass heats up faster than a large mass. That is a law of nature. Low-H2O radiators are much lighter and contain far less water than other radiators or underfloor heating systems. Thus they need no prior self-heating, and also immediately transfer the heat to the room. The ultra-modern aluminium and copper Low-H2O heat exchanger responds several times faster than underfloor heating or other radiators. The heating also stops after reaching the optimal room temperature. For this reason, the Jaga Low-H2O radiator provides greater comfort with lower energy consumption.

Low-H2O now even more compact with dbh option!

Heat pumps, solar energy systems and condensing boilers are most efficient at relatively low water temperatures, sometimes even as low as 35°C, which means that much bigger, more powerful radiators are normally required. No such problem for Low-H2O radiators, because when combined with Jaga's innovative DBE technology, the same radiator emits 2 to 3 times the heating output, with no increase in size. The new top of the range DBE Pro version is also able to deliver free, passive cooling in conjunction with reversible heat pumps. DBE technology gives you the opportunity to make the best use of the full range of new, environmentally-friendly systems. Prepare yourself for the future!

Jaga Low-H20 and the Amazon forest

On this view of the amazon forest made from the Messenger Spacecraft, the wavelength of infrared light is substituted for blue light. The resulting image is crisper than the natural color version and gives a clearer view, but it makes plants appear red. An unwanted side effect which makes the image even more meaningfull because red is the color of danger! The Amazon forest covers 50% of the total tropic forest surface on earth and it is the most important carbon (CO2) absorber. It absorbs almost 20% of the 38 billion tonnes of carbon dioxide created by mankind every year. In spite of the enormous importance for the earth's climate, almost 10 000 km2 is destroyed every year by deforestation. If mankind wants to achieve an important improvement of the global cycling of carbon and therefore the speed and severity of future climate change, a significant reduction of global CO2-emissions and a severe protection of the world's forests is needed! Jaga LOW-H2O radiators can reduce the energy consumption of an average home of 140 m2 by 141 m3 gas/year, corresponding to CO2- emissions of no less than 293 kg/year! This is a significant amount if you consider that an average car can drive 2,000 km with these CO2-emissions.!

*The LCA or Life Cycle Assessment is a system to compare products and to improve their environmental profile. Government authorities are trying to standardise LCA systems and integrate them into the law. Jaga uses the Belgian Ecolizer 2.0 of Ovam [Public Waste Agency of Flanders], based on the Eco-Indicator EI-99 database. The lower the LCA score, the lower the adverse impact on the environment. Jaga Low-H2O radiators also consume less raw material than other radiators or heating systems. **Weight of the heat exchanger and the casing, although unlike conventional radiators, the casing does not affect the warm-up time and the energy consumption.
