<strong>ELCO</strong> boilers helped to solve flue pipes<br />
problem for modern residential complex.<br />
Mercato is a modern residential complex that consists of<br />
three 17-storey buildings with penthouses on top. From the<br />
windows of the apartments, there is a beautiful view of the<br />
sea and mountains. On the grounds of the complex there is<br />
a playground and sports ground, as well as a heated pool.<br />

The challenge<br />
The first concept for heat supply for this project was a standalone<br />
boiler plant room with traditional fire-tube boilers located about<br />
20m from the buildings. Due to the high emissions produced by<br />
this type of boiler, a high chimney was required. This would have<br />
needed a horizontal pipe to have been installed from the boiler<br />
house to one of the buildings, then a high chimney mounted<br />
on its facade. The total length of flue pipe would need to be<br />
approximately 80m. Obviously, such a chimney installation was quite<br />
costly - and, aside from that, it would also ruin the visual appeal of<br />
the complex, as the flue pipe would be installed close to playground<br />
and even block the view from one of the penthouses.<br />
Comment<br />
As a solution for this problem, we recommended installing <strong>ELCO</strong><br />
TRIGON® XXL SE boilers. These boilers have very low emissions<br />
that fall below most strict limits. It was calculated that for <strong>ELCO</strong><br />
boilers it would be enough to install pipework just 13m high in order<br />
to comply with emission requirements. Savings on the flue pipe<br />
covered the difference in cost between modern <strong>ELCO</strong> boilers and<br />
traditional fire-tube boilers.<br />
TRIGON® XXL SE — Class-leading<br />

The <strong>ELCO</strong> solution<br />
For this project, we supplied three TRIGON® XXL<br />
SE 1000 boilers. Flue gases from three boilers are<br />
discharged into common pipe. Simple chimney<br />
mounted outside close to the boiler house.<br />
