VENTO – THRIFTY WITH ENERGY, UTTERLY COMFORTABLE

A VENTO low-temperature radiator heats your home at the lower water temperatures, saving money without compromising on comfort.

ENERGY EFFICIENT

Heat sources like heat pumps are more efficient when running on a low temperature supply, even as low as 35°C. The temperature of a modern heating system will be between 35°C and 60°C, which is precisely VENTO’s optimal temperature range. Traditional central heating systems on the other hand run on water heated to 80°C. Lowering the temperature reduces your energy bill and your carbon emissions. And you help achieve the EU’s goal of carbon neutrality by 2050.

WHISPER IT: JUST PERFECT

The modulation system ensures you achieve your optimal temperature without needing a lot of technical knowledge. And you won’t be disturbed by the ventilators that generate additional convection heat. While other classic systems usually have three settings, the VENTO convection technology has a modulating thermostat to ensure it reaches your desired temperature quickly and noiselessly. The VENTO only works at full tilt when the temperature in your home has fallen to a low level. In that case the sound intensity at 1 meter of a model measuring 600mm by 1000mm is just 32dB(A), the level of a whisper.

But that’s not all, because when you use it with a heat pump set at no lower than 17°C you can also use a VENTO radiator to cool down your home. Homes are increasingly being well insulated, which increases the risk of overheating in the summer. The cooling kicks in automatically, generating a pleasant breeze.

Compact VENTO

The Compact VENTO is the ultra-low-temperature radiator that, thanks to its modulating control and integrated fans, provides you with pleasant heating comfort even at low temperatures. The big advantage of this model is that the fans are controlled fully automatically. This radiator has also been specifically developed for use in combination with renewable energy sources such as a heat pump. In addition, the VENTO can provide non-condensing cooling in combination with a heat pump.

Specification text

• Product:	ultra-low-temperature radiator with integrated fans for a boosted convection
• Finishing:	upper grille and side panels
• Pre-installed:	fully automatic fans
• Also supplied:	AC/DC adapter 240V/12V with 1,5 m power cable, VDI brackets with anti-lift (type Monclac), screws, plugs, air vent, blind plug and installation instructions
• Control:	fully automatic, modulating control. When plugging in, the fans will briefly operate to check their proper functioning. During their normal operation the fans will start when the bottom side remains warm during a certain amount of time. This may take 10 – 30 minutes.

For optimal cooling, the direction of the water through the radiator must be reversed, and the thermostatic head fully open. If the room temperature is higher than the maximum temperature setting of the radiator thermostat, the thermostatic head must be temporarily removed.
• Sound pressure:	max. 32 dB(A) at a distance of 1 meter, for a radiator with a length of 1.000 mm and a height of 600 mm

Sound pressure

The VENTO radiator is modulated. This minimises the amount of noise generated, making it virtually silent. The VENTO only works at full tilt when the temperature in your home has fallen to a low level. In that case the sound pressure at 1 meter of a model measuring 600mm by 1000mm is just 32dB(A), the level of a whisper.

How loud is a given decibel level?
dB(A)	Perception	Examples
10	Virtually inaudible	Breathing, falling leaf
20	Just audible	Radio studio, rustling leaves
30	Very quiet	Library (30-40), whispers
40	Quiet	Living room, quiet classroom, gentle hubbub, fridge
50	Moderate	Airconditioning, normal conversation, dishwasher

Connections

* = a reduction in heat output will occur when combining low temperature heating with a high temperature difference between inlet and outlet. Not suitable for cooling.
