Energy saving Improves energy eﬃciency and comfort whilst reducing bills.

A radiator that A radiator that produces more reduces energy bills comfort at less cost by up to !".#%

The power we use in buildings accounts for !"% of global Your choice of radiator determines how comfortable the consumption, and that has a massive impact on the heating in your home feels, and how much that comfort environment. But with smarter energy management, our costs. You know how a draught-free room at $"°c can still buildings can emit up to #"% less CO$. That’s something feel uncomfortable? the European Union are moving towards, by making energy consumption standards stricter. The energy saving radiant heat of the Stelrad Eco will soon fix that. And with the outstanding energy efficiency delivered by At Stelrad, we believe the heating industry has a major role to its preset valve, it reduces your bills by up to &".'%, too. play, by developing systems that work efficiently so that they produce more heat at lower temperatures. Thanks to the controlled flow of our unique direct intake technology, the water in the front panel reaches a That’s why we’ve developed Stelrad Eco, the energy saving temperature up to '"% higher than in a traditional radiator. radiator. It produces more radiant heat than traditional radiators - saving energy while raising comfort levels, all at a The Stelrad Radical energy saving radiator reaches reduced cost to the user and to the environment. its maximum temperature $(% faster than a traditional radiator.

It reaches its optimum performance level while a traditional heater is still heating up.

After only $ minutes it oﬀers up to '"% more radiant heat.

With higher radiant heat, the feeling of $"°C can be achieved at a lower temperature setting. The Stelrad Eco energy saving radiator’s unique and innovative technology raises comfort levels, and by working more eﬃciently, it reduces energy bills - with a saving of up to &".'%. In a traditional radiator the heat generated consists, on Raising comfort levels average, of "#% convection heat and $#% radiant heat - with more radiant heat limiting the feeling of warmth. The Stelrad Eco energy saving radiator increases radiant heat A radiator that delivers more heat, more eﬃciently. by up to %#%.

Domestic heating is usually based on convection and radiation. With convection heating, hot air rises from the heating elements, cools down, descends via the wall and is heated again. With radiant heating, infrared radiation is sent directly around the room regardless of airﬂows like wind or draughts.

Radiant heat heats up the room, furniture and people and is reﬂected back to create a more comfortable feeling, similar to the rays of the sun. Standing in the sun always feels much warmer, even if the surrounding temperature is no higher than in the shadow - because it is radiant heat. So the comfortable feeling of a room at $#ºC is achieved at a setting of & degree less (or even lower).

Up to !"% more At " minutes with %#% radiant heat means of nominal flow more comfort - at a lower cost At " minutes with nominal flow These thermal images demonstrate the improved radiant heat of the Stelrad Eco radiator.

So depending on the radiator size and type it is compared to, the Stelrad Eco energy saving radiator offers up to %#% more radiant heat. Supported by a Fast, convenient and RIBA & CIBSE CPD flexible fitting

Energy savings tested, Angle H Block Straight H Block with couplings assessed and declared by KIWA

KIWA is a highly respected Pan-European institute providing internationally recognised declaration services for systems and products. As an independent expert KIWA also carries out specialist testing, and the KIWA Gas Technology division has rigorously trialled the Stelrad Eco radiator to assess and declare its energy saving performance.

Compatibility Simple and quick to connect with Hydro Bock (H Block)

The Stelrad Eco radiator is compatible with the following:

Gas boilers

Electric boilers

Solar PV

Ground source heat pumps (GSHP)

Air source heat pumps (ASHP)

Biomass installations Preset thermostatic valve

The thermostatic valve regulates the water supply in the radiator. This valve is preset in the factory according to the radiator’s size, which guarantees optimum eﬃciency.
