Product detailed description
Vaillant uniSTOR plus VIH RW 200 is the newer generation of a stationary indirect water heater from the uniSTOR plus product line, designed to work with Vaillant air/water heat pumps. Compared to the older uniSTOR VIH RW series, it offers more compact dimensions, lower weight, and an improved energy efficiency class for hot water preparation, while maintaining the same principle - a large-surface smooth-tube heat exchanger optimized for the lower output temperatures of the heat pump.
What the "plus" range brings compared to the older generation
The uniSTOR plus range is the current development generation of Vaillant water tanks for use with heat pumps. Compared to the original model uniSTOR VIH RW 200 (rated volume 193 l, height 1 340 mm, empty weight 103 kg), the uniSTOR plus VIH RW 200 model is more compact (height 1 253 mm, smaller footprint 596 × 596 mm) and significantly lighter (empty weight 80 kg), which makes handling and installation in the technical room easier. The tank also achieves an A+ energy efficiency class for hot water preparation, which is several steps higher than the older generation, thanks to improved PU foam insulation and lower standby heat loss (1.25 kWh/24 h).
Technical specifications
- Actual tank volume: 185 l (suitable for a household up to 5 people)
- Dimensions (height/width/depth): 1 253 / 596 / 596 mm
- Turning dimension: 1 388 mm
- Empty tank weight: 80 kg
- Operating weight (filled with water): 277.6 kg
- Heat exchanger surface area: 1.9 m²
- Volume of the heating (primary) side of the heat exchanger: 12.6 l
- Maximum temperature of hot water: 85 °C
- Maximum operating pressure (heating and hot water side): 10 bar
- Cold/hot water and circulation connections: 3/4"
- Heating circuit connection: 1"
- Daily standby loss: 1.25 kWh/24 h
- Energy efficiency class for hot water preparation: A+
Construction and materials
The tank is made of steel with an enamel-coated (glazed) inner surface, ensuring the hygiene quality of hot water and long-term resistance to corrosion. As an additional anti-corrosion protection, a magnesium protective anode is used. The external thermal insulation consists of PU foam insulation with low thermal conductivity, which, in combination with the more compact dimensions of the tank, contributes to lower standby losses compared to the older generation of uniSTOR VIH RW.
Why choose this model
The uniSTOR plus VIH RW 200 model is a suitable choice for households that want the latest generation of tank with a better energy efficiency class and lower space requirements in the technical room - more compact dimensions (almost 9 cm lower height and 4 cm smaller footprint compared to the older VIH RW 200) can be decisive especially during renovations, where space in the boiler room or technical room is limited. The lower weight of the tank (80 kg vs. 103 kg) also simplifies the transport and installation of the tank at the installation site.
Installation
The tank is installed as a stationary (floor-standing) unit, with a footprint of 596 × 596 mm and a height of 1 253 mm. When planning the space in the technical room, it is necessary to also consider the turning dimension of 1 388 mm, which determines the minimum space required during the actual placement of the tank (e.g., door passage). It is connected to the heat pump heating circuit via 1" connections and to the hot water distribution in the house via 3/4" connections for cold/hot water and circulation.
Installation and commissioning must be carried out exclusively by a qualified installation company authorized for the installation of heat pumps and heating technology, according to the current installation and service manual from Vaillant for the uniSTOR plus VIH RW 200. We recommend also planning regular annual service, including inspection of the protective anode and setting of safety and control elements of the system.
Compatible accessories and assembly
- Vaillant air/water heat pump (e.g., aroTHERM plus series) - the main heat source for heating water in the tank
- Vaillant VPS R 100/1 M or VPS R 200/1 B buffer tank for stabilizing the heating circuit during hot water preparation
- Control and safety accessories (safety valve, expansion tank on the hot water side, etc.) according to current project documentation and local regulations
Difference compared to the uniSTOR VIH RW 200 model
Although both models (uniSTOR VIH RW 200 and uniSTOR plus VIH RW 200) serve the same purpose - hot water preparation in combination with a heat pump - they differ mainly in dimensions, weight, and energy efficiency class. The older generation has a slightly larger rated volume of the heat exchanger and a higher maximum hot water temperature (95 °C vs. 85 °C in the newer generation), while the newer "plus" generation offers a more compact and lighter design with a better hot water preparation energy efficiency class (A+) and lower standby losses. The choice between models therefore depends on specific space requirements, energy efficiency, and the availability of a particular model at the time of implementation.
Common questions
Is the uniSTOR plus VIH RW 200 a replacement for the older uniSTOR VIH RW 200?
Yes, it is the newer generation of the product line with improved parameters, mainly lower weight, more compact dimensions, and a better energy efficiency class for hot water preparation.
For how many people is the tank suitable?
The manufacturer states suitability for a household up to 5 people, but we recommend always verifying the specific sizing with the designer according to actual hot water consumption habits.
Why is the maximum hot water temperature lower than in the older model?
The newer generation is optimized for typical operation with a heat pump, where lower temperatures are used compared to gas boilers, which also contributes to higher overall system energy efficiency.
What is the warranty on the tank?
Warranty conditions are governed by the current commercial terms of Vaillant and the seller - we recommend checking the specific warranty duration at the time of purchase and ensuring installation by an authorized installation company, which is usually also a condition for full warranty coverage.
Recommended assembly with a heat pump
In a typical installation of a family house, the uniSTOR plus VIH RW 200 tank is combined with an air/water heat pump and usually also with a separate buffer (accumulation) tank for the heating circuit (e.g., Vaillant VPS R 100/1 M or VPS R 200/1 B). This division of tasks - one tank for hot water, the other for heating water accumulation - allows the heat pump control to independently prioritize hot water heating and heating according to the current needs of the household, without these two functions competing with each other in a single shared tank.
Switching between hot water heating and heating modes is ensured by a three-way switching valve controlled by the heat pump regulation - the system usually prioritizes rapid heating of the hot water tank and then returns to heating via the buffer tank.
Thermal disinfection and water hygiene
Even in the case of the uniSTOR plus VIH RW 200 tank, regular thermal disinfection (legionella protection) cycles are part of proper operation to eliminate any possible multiplication of legionella bacteria in the hot water distribution. This cycle can be programmed in the Vaillant heat pump regulation, and it is necessary to consider that the maximum hot water temperature in this model is 85 °C - we recommend consulting the frequency and temperature settings of the disinfection cycle with the installation company in accordance with current hygiene regulations.
Choosing the size of the tank in the uniSTOR plus VIH RW range
The uniSTOR plus VIH RW range offers, in addition to the 200-liter model, larger volume variants for households with higher simultaneous hot water consumption or for buildings with multiple bathrooms. When choosing the correct tank size, the most important factor is the number of people in the household, the number of simultaneously used consumption points (e.g., shower and bathtub at the same time in multiple bathrooms), and hot water consumption habits. The 200-liter class model with the stated rated volume of 185 l is a suitable choice for a household up to 5 people with normal, not extreme, simultaneous consumption.
Why to buy through an authorized partner
We always recommend purchasing and having the uniSTOR plus VIH RW 200 tank installed by an authorized Vaillant dealer and installation company. This ensures not only correct installation and system setup in accordance with the manufacturer's instructions, but also full validity of the warranty conditions and availability of original spare parts (e.g., protective anode) throughout the entire lifetime of the device.
