Saint Andres health care facility in Biddeford is another example of one of our best commercial contractors work. Eastern Mechanical in Biddeford Maine was subcontracted to replace the (2) existing oil boilers at the facility and replace them with (2) new Viessmann Vitocrossal high efficiency condensing boilers.
Ron Dunsmoor of Eastern Mechanical was awarded the project and Coastal Winair assisted with product application and design.
The main scope of the project was the boiler replacement, swapping the existing oil boilers to the new Viessmann Vitocrossal condensing gas boilers was quite an undertaking. It included venting the new high-efficiency condensing boilers with 8″ poly-propylene piping – which had to be vented up an existing chimney. Also on the scope was the addition of (2) Viessmann 120 gallon stainless steel indirect water heaters for domestic hot water for the building. The Viessmann storage tanks have the feature of stackability, which fit nicely into the new mechanical room.
Eastern also installed a Viessmann staging control with a lead-lag feature. The control has numerous functions; including modulation of the boilers gas valve in order to provide just the needed energy for the building. Although the (2) boilers have the heating capacity of over 2,000,000 BTU/hour; the control can evaluate the system and provide just the right amount of energy the building asks for. This feature – along with the higher combustion efficiency, will provide increased fuel savings for years to come.
The St. Andres health care facility was a rewarding project for Coastal Winair – it allowed us to work closely with the contractor on the heating system design and provided the flexibility and timing he needed to make changes necessary along the way . We are confident St Andres will achieve the energy savings and long-term sustainability that they are looking for with the Viessmann boilers.
