Wall-mounted condensing gas boiler Hi-Therm VITA CONDENSE

A wall-mounted, dual-circuit boiler with a closed combustion chamber for heating and domestic hot water. It is particularly well suited to low-temperature heating systems, including water-based underfloor heating.

Four models: VITA CONDENSE 23, 30, 36 and 42. Heating modulation is 20–100%; heating energy efficiency class A and NOx class 6. Hot-water flow is 11–20 l/min at ΔT = 30 °C, depending on the model.

A stainless-steel primary heat exchanger recovers heat from the flue gases, while a separate plate heat exchanger provides domestic hot water. The variable-speed pump and fan help the boiler adapt to changing demand.

Efficient low-temperature heating

Condensation depends on the return-water temperature: a lower return temperature allows more heat to be recovered. The efficiency figures in the technical table apply to the specified test conditions, not to every operating mode.

Comfort and control

The LCD panel controls heating and hot-water settings. An outdoor temperature sensor, room thermostat or modulating Wi-Fi SMART thermostat can be connected as optional accessories. Built-in diagnostics display fault codes; the closed combustion chamber is part of the multi-level safety system.

Features and controls

  • Closed combustion chamber and premix burner; NOx class 6.
  • Stainless-steel primary heat exchanger and separate plate heat exchanger for domestic hot water.
  • Variable-speed circulation pump and fan; 20–100% modulation.
  • LCD control panel; supports an outdoor sensor, room thermostat and modulating Wi-Fi SMART thermostat (MRTR). These controls are optional accessories, not built-in Wi-Fi.

Fuel: models 23/30/36 support natural gas and LPG propane after the appropriate professional conversion; model 42 is for natural gas only.
