Project Background

The building is a located in a beautiful neighbourhood in the heart of the city on the banks of the Red river.  A concrete 10 storey apartment building with 30+ units, Five Fifty Five River was served by a boiler system (space heating) that was near the end of its life.  Additionally there were issues surrounding adequate domestic hot water to all suites.

Project Solution

NRG worked to design a hydronic system that would replace the aging boiler, including designing a new hydronic distribution that would provide a more even service.  This resulted in the installation of (2) Camus Dynaflame units (natural gas fired) and all related piping.  To satisfy domestic hot water needs (2) Thermo Turbomax indirect tanks (electrically fired) were added, as well as (2) Taco plate heat exchangers that use excess boiler heat from the return loop as a preheat to the domestic hot water supply.  This allows the return hydronic loop to shed heat to the domestic hot water loop, so as to drastically reduce the amount of electricity consumed by the domestic hot water system while only marginally increasing the natural gas consumption on the boilers.

The heat recovery aspect of the system helps boost the Internal rate of return of the project, and the fuel conversion aspect allows disparate energy sources to help mitigate risk of future spikes in either electrical or natural gas rates.  This system ensures that tenant comfort is satisfied while minimizing utility bills.
