Vaillant VU 35CS/1-5 ecoTEC plus IoniDetect + VIH R 150 B + sensoCOMFORT 720
Code: 0010044678Related products
Product detailed description
If a house or business premises has several bathrooms or other draw-off points used at the same time, comfort depends mainly on the hot water reserve. This package therefore adds a 144 l floor-standing cylinder to the wall-hung condensing boiler with an output of up to 34.8 kW – the largest of the three variants with the VU 35CS/1-5 boiler and the sensoCOMFORT 720 controller (the other two have 68 l and 117 l cylinders). It is suitable for buildings with a higher heat loss and, at the same time, higher hot water consumption.
Scope of supply
- Vaillant VU 35CS/1-5 ecoTEC plus IoniDetect boiler – wall-hung, condensing
- uniSTOR VIH R 150 B floor-standing cylinder, 144 l, class B insulation
- sensoCOMFORT 720 controller
- hot water temperature sensor fitted in the cylinder
The supply does not include the connecting pipework between the boiler and the cylinder, the hanging kit or the under-boiler spacer frame. According to the Vaillant price list, these two mounting parts are only included in the packages with 10 and 25 kW boilers. If you want to control the heating remotely via the app, add the sensoNET internet module.
uniSTOR VIH R 150 B cylinder
Of the three cylinders in the 35 kW packages, this one has the largest heat exchanger surface area (0.9 m²) and a heat exchanger with a maximum output of 35.9 kW. With continuous draw-off it produces 674 l of hot water per hour, heats up from 10 to 60 °C in 18.8 minutes, and its daily heat loss is 1.2 kWh. Both the steel vessel and the heating coil are enamelled on the inside and complemented by a magnesium anode; the drain valve makes maintenance easier and the adjustable screws make levelling on the floor easier. The height of 988 mm, the dimension of 590 mm and the weight of 79 kg without water are important when planning how to move it into the boiler room.
The boiler and its capabilities
The VU 35CS/1-5 ecoTEC plus IoniDetect boiler works with a 1:10 modulation ratio and a rated output of 4.0–34.8 kW at 80/60 °C (4.3–37.7 kW at 50/30 °C). For hot water heating it reaches up to 39.7 kW. IoniDetect technology evaluates combustion and fine-tunes it automatically when the gas composition is different. The boiler, the controller and other devices communicate via the eBUS – the system can therefore be extended with a heat pump in a hybrid configuration, solar water heating or central heat recovery ventilation.
sensoCOMFORT 720 controller
The wall-mounted system controller provides weather-compensated control of the heating and, at the same time, controls cylinder heating based on the sensor included in the package. On the 3.5" display with backlit touch buttons, you can set time programmes with the help of the assistant, as well as the heating curve and the screed drying programme. In a larger building, you can take advantage of control of up to 9 heating circuits with expansion modules and the connection of up to 4 remote controls; the controller also supports a cascade of 2 to 7 boilers.

Frequently asked questions
When is a 144-litre cylinder worth choosing over a smaller one?
When hot water is drawn at several points at the same time, for example when showering in several bathrooms. The VIH R 150 B has a continuous output of 674 l/h and the largest capacity of the three 35 kW packages with the sensoCOMFORT 720.
How much space does the cylinder need?
It is a floor-standing cylinder with a height of 988 mm, a dimension of 590 mm and a weight of 79 kg without water. It is installed on the floor and levelled using the adjustable screws.
Which parts are not included in the package?
The connection between the boiler and the cylinder (the boiler has G 1/2" connections, the cylinder has an R 3/4" heat exchanger connection). The hanging kit and the under-boiler spacer frame are not included with the 35 kW packages, nor is the sensoNET module.
Can a heat pump or solar water heating be connected to the system later?
Yes. Both the boiler and the sensoCOMFORT 720 controller are ready via the eBUS for hybrid operation with a heat pump, solar water heating and central ventilation.

Easter Bunny in the logo - intended for the success of the company
Pink dwarfs and cute animals stand around and admire the miracle of the egg. Johann Vaillant is fascinated by the scene and decides to buy both the picture and the copyright. For Vaillant, this means the establishment of its brand and an extremely successful story.
Very distinctive brand profile
Since 1899, the motif has adorned all products, catalogs and brochures. In a few short years, Vaillant built an excellent reputation that spread throughout Germany and even beyond its borders. Vaillant gave its logo clear lines and outlines. "The Bunny in the Egg" remains the central theme, but the word "Vaillant" is added.
Many Germans know that the Vaillant Bunny belongs to a company based in North Rhine-Westphalia. Moreover: more than 70% of all Germans have heard of the company Vaillant. In Austria and the Netherlands, the company achieves similar results for its image.
