Biasi Riva PLUS Modulating Gas Boilers

Part of Eco-Friendly Campus Retrofits

Guelph Campus Co-operative.
By Students. For Students. Since 1913

 When the Guelph Campus Co-op was looking to update the central heating systems in several of their 8 unit apartment buildings, they were looking to do so, while fulfilling their mandate.

“Affordable and close to campus, the Co-op operates lodging houses and apartment buildings below conventional market rates.  It's more affordable because our mandate is to serve students, not make big profits. The Co-op has a mandate to pursue environmental efficiencies wherever possible. This is being demonstrated through retrofits... and procurement of energy saving appliances.”

Located on a lovely spot near the river and trails, Guelph Campus Co-operative owns and manages five identical 8 unit apartment buildings that are 45 years old. They are now heated with BIASI.

Efficient, Reliable and Affordable.

                                                                                
There were a number of factors that influenced the decision to replace the older boiler in each building with two, modern units:

• Install high quality equipment at an affordable cost.
• Improve system efficiency to reduce on-going heating expenses.  
• Replace older equipment, which would become more costly to maintain in the future.  
• Find modulating condensing gas boilers that could perform at highest efficiencies when matched with the existing high temperature radiation system in the building.
• Create the ability for system staging.
• The ability to direct vent the units.
  

The Two Riva Plus boilers were vented using factory provided powder-coated steel piping.  *Note the Riva Plus can also be vented using CPVC.

The Tekmar 262 allows for staging of the two boilers and indirect hot water heater in the system, providing a large amount of data that is very helpful and understandable.   

A separate part of the efficiency project was the addition of solar hot water heaters pictured here. The solar collection panels can be seen on roof of the building pictured above
