Reliable domestic hot water – all day long!

Vitotrans 300 is a packaged high-performance, high-output domestic hot water (DHW) heater, designed for commercial applications requiring high volumes of DHW, such as resorts, recreation and hospitality complexes, and hospitals. Vitotrans 300 works in conjunction with a heating boiler and employs a plate heat exchanger to quickly and efficiently heat the required domestic hot water – no more need for multiple DHW tanks.

Guaranteed on-demand hot water – all day long
Used as an extension to any hot water heating system, the on-demand design of the Vitotrans 300 provides a consistent flow rate all day long for systems with varying load requirements. It accurately provides 5 to 180 GPM of DHW when combined with a DHW buffer tank.

Completely hygienic
The unit's on-demand design avoids lengthy DHW storage, thereby eliminating the risk of legionella and limiting the build-up of bacteria. A selectable sanitation function also allows customization of temperatures and times of operation (buffer tank systems only).

The benefits at a glance

  • Efficiency.  Designed as an extension to the primary heating system, the Vitotrans 300 only requires a 30% increase of a building's overall BTU requirements to cover all DHW heating needs.
  • Increased sustainability.  Energy savings realized by eliminating the need for a dedicated boiler for DHW production.
  • Decreased cost of installation.  No need to install batteries of DHW storage tanks. No need for gas piping or wall venting penetrations.
  • Ease of installation.  Compact size of pre-assembled unit reduces required floor space. Easy access to all componentry and no gas piping or wall vent requirements allow for stress free installation.
  • Easy system integration.  Bacnet IP communication for easy integration into BAS/BMS systems.
  • Maximum life expectancy.  As a result of its burnerless design, sediment buildup and thermal stress are reduced, ensuring minimal maintenance and prolonged service life.
  • Flexibility.  Accommodates a wide range of system applications and flow rates, from 5 to 180 GPM.
