The heating requirements in apartment buildings and industrial buildings are often very high, and so are the running costs for heating and hot water – especially if you still use fossil fuels. The conversion is worth it – especially when it’s as easy as with ETA. Already during the development of the ETA PE-K pellets boiler, the quality company from Upper Austria had not just new builds in its sights, but particularly also renovations. In most cases, no large conversions are required for boiler replacements, and existing conditions can be used optimally. For example, a pellet store can be placed up to 20 metres away – for instance where the oil tank used to be.
