Characteristics

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

Ideaal voor warmtepompen

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

Ideaal voor warmtepompen

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.

Technical details

Planar VENTO

The Planar VENTO ultra-low-temperature radiator is the decorative version in our VENTO range. The fully automatic radiator with integrated fans provides an enhanced convection. This This makes the radiator extremely suitable for low and ultra-low supply temperatures, such as with heat pumps. In addition, the VENTO can provide non-condensing cooling in combination with a heat pump.

Specification text

• Product:	decorative ultra-low-temperature valve radiator with a flat front and integrated fans for a boosted convection
• Finishing:	decorative flat front, upper grille and side panels
• Pre-installed:	fully automatic fans, preset Heimeier 4368 or 4369 valve insert, air vent and blind plugs
• Valve insert:	The integrated adjustable valve insert (without thermostatic head) is factory-fit on the right side of the radiator, CEN certified, tested in accordance with EN215 and compatible with thermostatic heads M30 x 1,5 mm. The thermostatic valve insert is factory-set in relation to the size of the radiator. This presetting ensures optimum throughput in the radiator. Factory setting for two-pipe systems, also suitable for one-pipe systems (as long as the valve insert is adjusted to position 8).
• Also supplied:	AC/DC adapter 240V/12V with 1,5 m power cable, VDI brackets with anti-lift (type Monclac), screws, plugs 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.
• Cooling:	in combination with a heat pump. The inlet temperature must remain above the dew point. 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
• Connections:	6 x ½” female connection (2 x ½” lateral bottom connection included).
• Lugs:	2 pairs of mounting lugs up to 1.600 mm and 3 pairs from 1.800 mm
• Packaging:	Every radiator is sturdily packaged in high-quality cardboard and wrapped in plastic. The radiator’s characteristics are shown on the label: type – height – length.
• Warranty:	10 years for the radiator and 2 years for the electrical components, as long as the installation instructions have been followed and Stelrad’s warranty conditions have been met.
• Paint process:	All radiators are degreased, phosphated, cataphoretically primed and powder-coated in Stelrad white 9016 as standard.

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
