Tank-type Domestic Hot Water Heater Vaillant VIH R 200/6 B, 200 L capacity

Vaillant VIH R 200/6 B is a tank-type domestic hot water heater with 200 litre capacity, designed for indirect connection to a central heating system or an external heat source. The cylinder stores and delivers domestic hot water at a stable temperature for bathrooms, kitchens and sanitary installations. The unit is intended for residential properties and small commercial sites where a reliable buffer of hot water is required.

Advantages

The vertical tank construction provides compact floor footprint and effective stratification to maintain temperature layers. Corrosion protection and internal coatings extend service life and reduce maintenance needs. The heater is compatible with common central heating circuits and allows for simple integration with boilers, heat pumps or other indirect heat sources. Insulation around the tank minimises standby heat loss, improving overall energy efficiency for domestic hot water storage.

Suitable for

• Single-family homes and apartments with central heating
• Small commercial premises requiring domestic hot water (offices, guest houses)
• Systems using a boiler or heat pump as an indirect heat source
• Applications needing a stable hot water buffer for multiple draw-offs

How to use

Connect the unit to the central heating circuit or chosen heat source following local plumbing and heating regulations. Commission the heater with appropriate safety valves, temperature sensors and circulation piping as required by the system design. Set the control and mixing devices on the primary heat source to achieve the desired storage temperature. Regularly check valves, insulation condition and anode or corrosion protection according to the manufacturer's maintenance schedule to ensure reliable operation.

Usage recommendations

For efficient and safe operation, size the heater according to peak demand, ensure compatible heat source output and maintain installed safety devices. Periodic inspection of the tank's corrosion protection, insulation integrity and hydraulic connections will help maintain performance and extend service life.
