Heating solutions for apartment buildings

The buffer storage tank – the heart of heat distribution
Heat is stored here, which in turn can be accessed at any time if more energy is needed. So the buffer storage tank evens out peak and reduced loads and thus ensures a uniform and more efficient operation of the heating system and also a longer lifetime of the boiler. A well-adjusted stratified buffer significantly enhances comfort as well.

Efficient heat storage using solar power
As a central element in the heating system, the stratified buffer storage tank plays a key role: In addition to absorbing energy from biomass, it also absorbs the heat generated by the solar thermal system and makes it available as needed – for hot water preparation as well as for heating support. This enables intelligent utilisation of energy surpluses, balances load fluctuations, and protects the boiler. This ensures not only consistent and economical operation but also significantly enhances living comfort—sustainably and efficiently.

Heat recovery via condensing heat exchanger
The condensing heat exchanger extracts the energy from the exhaust gases produced during combustion and feeds it into the heating system.  This process enables fuel savings of up to 10% with the right operating procedures!

Always hygienic, always fresh
The fresh water module ensures that the buffer storage tank is used even more efficiently. When hot water is needed in the house, the fresh water module kicks in: using the instantaneous water heater principle, it heats fresh cold water as needed and hygienically – exactly when it is required. For maximum comfort and consistently clean hot water.

Optimally harnessing the power of the sun:
The perfect stratification of solar heat into the buffer storage tank is made possible by the stratified charging module. This ensures optimal use of solar thermal energy for hot water preparation and heating support. For example in the morning when the sun is weak, the module supplies the lower half of the buffer. Once the sun is sufficiently strong to heat the upper, warmer buffer strata, the system switches to the upper half.

Clean separation for safe systems
Whenever heating circuits need to be separated, the ETA system separation module is used – for example, to separate residential heating from frost-protected areas such as workshops, stables or open areas. Separation also protects against damage in old underfloor heating systems or stable heating systems that introduce oxygen or pollutants into the system. The media are reliably separated from each other using a plate heat exchanger – similar to solar thermal systems.

Heat distribution has never been easier: plug it in, and you're done!
This is how quickly a whole system can be installed: you've got your heat distribution under control with just a plug and a data cable. The ETA heating circuit module is suitable for all types of heat distribution - i.e., underfloor, wall and/or radiator heating as well as fan heaters.

The ETA heating circuit module for 2 mixing heating circuits saves a lot of time and money during installation, because there is no need to lay sensor lines, pump and mixing cables. All components are connected to the already integrated control system.
