Small boiler,

Outstanding performance

The ETA PelletsCompact needs little space and is the ideal pellet boiler for renovations or new builds of larger residential buildings and office spaces.

It is only about 130 cm high, about one metre long and not even 95 cm deep – but it heats large residential buildings or small company buildings.

Can be set-up anywhere

The ETA PelletsCompact (only for 20- 32 kW) can be operated with external air , i.e. the combustion air can be piped directly to the boiler from outside. This means that the boiler can also be situated in heated buildings without creating unwanted draughts, or in rooms with extract ventilation.

In common with its smaller relation, the ETA PU, the boiler comes equipped with a built-in control system capable of controlling a domestic hot water cylinder, a buffer vessel and two heating circuits as standard. With an internet connection it can also be configured to send you emails when it is running low on fuel, or if the ash can needs emptying.

Its built-in vacuum system is capable of pulling fuel pellets from a bulk store up to 20 metres away to fill its day hopper, which gives you extra flexibility when siting the boiler.
