Installation of a Sharp ZU1 Wall-Mounted Heat Pump | 18,000 BTU on the roof in Pierrefonds

A technical installation on a flat roof in Pierrefonds: performance, reliability and energy efficiency

At AirGreen , every wall-mounted heat pump installation project is unique. We recently completed a flat roof installation in Pierrefonds , west of Montreal, featuring the Sharp ZU1 18,000 BTU Wall-Mounted Heat Pump , a high-performance, quiet model perfectly suited to the Quebec climate. This type of roofing work requires precision, expertise, and special attention to the stability and durability of the anchors.

A wise choice: the Sharp ZU1, a concentrate of technology

The model installed here, the Sharp ZU1 18,000 BTU , uses R-32 refrigerant , known for its low global warming potential (GWP). This wall-mounted mini split is ENERGY STAR® certified for cold climates and offers heating performance down to -27°C . It is a popular choice among homeowners in Pierrefonds and across the island of Montreal , looking for an eco-responsible energy solution without compromising on comfort.

Technical specifications of the Sharp ZU1:

• Heating capacity down to -27°C

• SEER2 : 24.0 | HSPF2 : 10.0 | EER2 : 13.0

• Built-in Wi-Fi for smart remote control

• Outdoor noise level : 52 dB(A) | Indoor: between 25 and 49 dB(A)

• Eligible LogisVert grant: $2,640

• R-32 refrigerant , more ecological and efficient

• Exceptional warranty: 10 years parts, labor and compressor

Special features of flat roof installation

This project in Pierrefonds presented a unique installation challenge: installing the outdoor unit directly on the roof of the residential building. To achieve this, our team opted for a raised, stabilized base consisting of:

• Anti-corrosion metal legs mounted on treated wooden beams , well anchored to prevent any movement .

• Optimized fan orientation towards the outside to ensure good air release.

• Frost and heat resistant supports , allowing durability in all seasons.

• A secure power supply with a circuit breaker box mounted on the brick chimney.

Why install a heat pump on the roof?

Installing a heat pump on a flat roof is sometimes a necessity, especially when there is limited floor space or the client wants to free up the facades. This has several advantages:

• Saves floor space , ideal in urban areas such as Montreal

• Less noise at ground level , a significant advantage in quiet residential areas

• Protection against potential ground damage (snow, debris, animals)

However, this requires in-depth expertise to ensure long-term sealing, stability and proper functioning.
