Introduction to the Installation of a Central Heat Pump in an Old House
At AirGreen, we take pride in overcoming the technical challenges presented by installing central heat pumps in historic buildings. One of our recent installations in a stone house dating back to 1875 in Montréal highlighted the expertise required to integrate modern technology into an older environment, while maximizing the energy benefits for homeowners.
The Challenge of Installing a Central Heat Pump in a Historic Home
Older homes, particularly those built in the late 19th century, often present unique constraints when it comes to renovation and the installation of new heating, ventilation, and air conditioning (HVAC) systems. In this particular case, the stone house from 1875 had thick walls and a complex structure, making the installation of modern air conditioning systems a difficult task.
Assessing the Client’s Needs
Before we began the installation, it was essential to understand the client’s specific needs. The stone house had insufficient insulation, leading to significant heat loss in the winter and stifling heat in the summer. The client was looking for a solution that could regulate temperature efficiently while reducing energy costs. We opted for a central heat pump from Bosch, a brand known for its reliability and energy efficiency.
Choosing the Model and Capacity of the Heat Pump
The model we installed was the Bosch BIVA IDS Premium R-454B, a unit compatible with installations in older homes, offering a perfect balance between heating and cooling power and energy efficiency. With a capacity of 3 tons (36,000 BTUs), this heat pump is designed for medium to large spaces, making it ideal for the layout of the stone house. The use of the R-454B refrigerant enhances the environmental benefits of the installation, ensuring optimal performance while meeting environmental standards.
Installation Details
One of the major challenges of this installation was integrating the system into the existing structure. The thick walls of the stone house required a more careful approach to drilling openings and running the necessary ducts. Additionally, air distribution through such a space demanded thoughtful planning to ensure optimal comfort in all rooms.
Preparation and Planning
Before beginning the installation, our technicians conducted a thorough feasibility study. They analyzed the dimensions of the rooms, checked the existing systems (including plumbing and electrical), and designed an installation plan that would minimize impact on the historical integrity of the house. With clear communication with the client, we obtained approval to proceed without compromising the building’s architectural structure.
Duct Installation
The installation of the ducts was one of the most delicate aspects of this project. In a stone house, it is crucial to minimize invasive work, which required the use of flexible and discreet ducts that would not detract from the aesthetic of the rooms. Our technicians ensured that each duct was carefully installed, using modern materials without disturbing the visual integrity of the house.
Installing the Outdoor Unit
The outdoor unit of the Bosch BIVA IDS Premium R-454B heat pump was installed in the garden, at a sufficient distance to ensure good thermal performance while minimizing noise. The available space was limited, which made it necessary to use a custom support structure to secure the unit and avoid damaging the surrounding plants.
The Benefits of This Installation
This installation allowed the client to enjoy several immediate and long-term benefits:
-
Energy Efficiency: The Bosch model is designed to optimize energy use, significantly reducing heating and cooling bills.
-
Thermal Comfort: With precise temperature control, the house remains comfortable year-round, while improving indoor air quality.
-
Eco-Friendly: The choice of the R-454B refrigerant helps reduce the home’s carbon footprint while maintaining optimal performance.
-
Subsidies: The client also benefited from subsidies provided by Hydro-Québec through the LogisVert program, which helped reduce the installation cost.
Conclusion: The Importance of AirGreen’s Expertise
