Objectives
- Reduce energy consumption and greenhouse gas emissions by transitioning to a renewable energy heating and cooling solution.
- Improve overall indoor comfort throughout the year.
- Lower long-term heating and hot water costs.
Installation Process
The installation was carried out by a certified HVAC contractor – Hex energy. The steps involved were as follows:
1. Site Evaluation: The Hex energy assessed the properties to find the best locations for the outdoor units (condenser) and indoor unit (hot water cylinder/buffer vessel). They ensured proper spacing, ventilation, and accessibility for future maintenance.
2. Outdoor Unit Installation: The condenser were placed on concrete pads within the back garden. The units were appropriately levelled, and electrical lines were connected.
3. Indoor Unit Installation: The hot water cylinder/buffer vessel were installed in the loft. The HVAC team made the necessary connections to the heat pump and integrated it with the appropriate controls.
4. During commissioning, the entire system was thoroughly tested for heating and hot water modes to guarantee their functionality.
Performance and Results
The air source heat pump was monitored following installation to evaluate its performance and cost-effectiveness. The following results were observed:
1. Environmental Impact: The transition to the ASHP led to a considerable decrease in greenhouse gas emissions. The clients have significantly reduced their carbon footprint, contributing to a greener environment.
2. Year-Round Comfort: The ASHP’s provide consistent and comfortable indoor temperatures throughout the year, regardless of the outside weather conditions.
3. Payback Period: The initial investment in the air source heat pump is projected to be recouped within eight years due to the substantial energy savings.
Conclusion
This case study demonstrates the successful implementation of an air source heat pump in two residential properties. The clients have benefited from reduced energy expenses, improved comfort, and a positive environmental impact. Air source heat pumps offer an excellent alternative to traditional heating and hot water systems, especially in regions with moderate climates, providing an eco-friendly and cost-effective solution for homeowners.
