Household heat exchange units (household heat exchange stations – BOST) are an opportunity how to make each flat in a residential building independent in terms of hot water production and heating. This concept is effectively used not only for renovations and new constructions of residential buildings but also for multi-generation family houses. Household heat exchange units provide comfort and are able to provide instant hot water and heating requirements in any season, independently in each flat. Each flat has a separate meter of hot and cold water consumption allowing accurate costs monitoring.

Energy saving

Compared to the conventional concept (central heat supply), the greatest energy saving is achieved by  household heat exchange units by energy saving which represents a heat loss on the route from the heat producer to the residential building. Total energy savings can be 2 to 24 kWh/m2/year.

The concept consists of a single heat source in the house (basement) providing hot water production (primary circuit) for all household heat exchange units that are connected to the source.

UNIVENTA household heat exchange units provide:

  • contain the PM pressure regulator for precise control between heating and hot water heating
  • sound- and thermal-insulated pipes
  • a large plate heat exchanger made of high-grade steel prevents scaling in the system by its structural design
  • a modular system allows you to make household units with all necessary components
  • a slight resistance of the household unit – larger pipe dimensions than competitors
  • interchangeability of spare parts
  • adjustable circulating pump according to consumption, water temperature or the differential difference
  • the household unit can be mounted on a storage tank and also directly to a flat
  • operation via a single button
  • flow rate up to 40 l/min.

Household heat exchange units can be used for:

  • multi-generation family houses,
  • residential buildings,
  • multifunctional buildings,
  • buildings with multiple tenants.

The TW household heat exchange unit uses heated water from the source (standpipe) through an integrated plate heat exchanger made of high-grade steel. It heats hot water on a flow heating principle. Its structural design virtually eliminates scaling even in very hard water. A sufficiently large heat exchanger in different power ranges ensures a stable and constant temperature at all offtake points even at a maximum consumption. Connection tubes of high-grade steel of Ø18 mm in diameter are resistant to corrosion.

It is produced in these standard designs:

  • TW1 Mini - output of 37 kW at 65 °C, flow rate 15 l/min.
  • TW2 Mini - output of 42 kW at 65 °C, flow rate 17 l/min.

(Flow rate at ΔT 35 ºC)

In addition to standard types we can also implement production according to your requirements.

A complete WK household heat exchange unit ensures hot water production and space heating in a flat. Different power ranges of heat exchangers enable you to select the optimal design of the household unit to ensure the desired thermal comfort. A pressure-controlled proportional regulator (PM-regulator) delivers required hot water with a constant input temperature for small and large numbers of offtake points. When the water from the offtake point is not used the entire hydraulic system is reliably protected against calcium deposits.

It is produced in these standard designs:

  • WK1 - output of 36 kW at 65 °C, flow rate 15 l/min.
  • WK1M - output of 42 kW at 65 °C, flow rate 17 l/min.
  • WK2 - output of 50 kW at 65 °C, flow rate 20 l/min.
  • WK3 - output of 38 kW at 50 °C, flow rate 15 l/min.
  • WK1 Mini - output of 29 kW at 65 °C, flow rate 12 l/min.
  • WK2 Mini - output of 37 kW at 65 °C, flow rate 15 l/min.

(Flow rate at ΔT 35 ºC)
