Project Overview: This project involved the full refurbishment of a residential property, including the installation of a Viessmann Vitocal 151-A air-source heat pump system. The project provided efficient heating solutions for both the ground floor (with underfloor heating) and the upper floor (with aluminum radiators). The system integrated a 100e thermostat for precise temperature control and a seamless indoor and outdoor unit setup. The heat pump system was designed to ensure energy efficiency, sustainability, and long-term comfort in the home.

Key Components:

1. Viessmann Vitocal 151-A Heat Pump:
   • Type: Air-source heat pump
   • Outdoor Unit: Mounted on the roof of the boiler house, ensuring optimal performance and minimal disruption to the home’s aesthetics.
   • Indoor Unit: Located in the plant room with the associated manifold and distribution equipment.
   • Efficiency: Designed to deliver high efficiency, reducing energy consumption while providing consistent heating and hot water throughout the home.
   • Capacity: Suitable for the size and thermal load requirements of the home.
2. Underfloor Heating (Ground Floor):
   • The ground floor was equipped with underfloor heating, providing even and comfortable heat distribution.
   • Installation: The underfloor heating system was embedded in the flooring, enabling low-temperature heating that worked seamlessly with the Viessmann Vitocal heat pump.
   • Energy Efficiency: Underfloor heating proved to be a highly efficient solution, reducing energy consumption while maintaining a comfortable indoor climate.
3. Aluminum Radiators (Upstairs):
   • The upper floor was fitted with sleek and stylish aluminum radiators, which provided effective, rapid heating where needed.
   • Design: The aluminum radiators offered a modern aesthetic and were highly efficient, working in combination with the Viessmann Vitocal heat pump to ensure even heating distribution across all rooms.
4. 100e Thermostat:
   • A 100e thermostat was installed for precise and user-friendly control over the heating system.
   • Smart Features: The thermostat allowed for remote management and programmable schedules, enhancing energy efficiency and user convenience.

System Configuration:

• Outdoor Unit: The Viessmann Vitocal 151-A’s outdoor unit was mounted on the roof of the boiler house. This ensured optimal airflow and reduced the footprint of the system within the property.
• Indoor Unit: The indoor unit, located in the plant room, was connected to the underfloor heating manifold and the aluminum radiators. The system was configured for both heating and hot water supply.
• Plumbing & Distribution: The system was connected to the underfloor heating manifold, ensuring optimal flow and distribution of warm water throughout the ground floor.
• Thermostat Control: The 100e thermostat was strategically installed for easy access and control of the temperature settings for both the ground floor and upstairs.

Scope of Work:

1. Planning & Design:
   • The home’s thermal needs were assessed, and the heat pump system was appropriately sized.
   • The outdoor and indoor units were placed for optimal efficiency and aesthetics.
   • The Viessmann Vitocal 151-A was integrated with the underfloor heating and aluminum radiators.
   • The 100e thermostat was placed and configured for maximum control and ease of use.
2. Installation:
   • The outdoor unit was mounted on the roof of the boiler house.
   • The indoor unit was installed in the plant room, with proper connections to the manifold and heating circuits.
   • Underfloor heating pipes were laid on the ground floor and connected to the manifold.
   • Aluminum radiators were installed upstairs and connected to the heating system.
   • The 100e thermostat was wired and configured to control the system efficiently.
3. Commissioning & Testing:
   • The full system was tested to ensure the heat pump operated at optimal efficiency.
   • The underfloor heating and radiator circuits were balanced to ensure consistent heating throughout the home.
   • The thermostat was configured to ensure accurate and responsive temperature control.

Expected Outcomes:

• A fully integrated, energy-efficient heating system that ensured consistent warmth and comfort across the home.
• Improved energy efficiency and reduced heating costs due to the use of the Viessmann Vitocal 151-A heat pump and underfloor heating.
• A modern, aesthetically pleasing system with minimal disruption to the home’s layout and design.
• Enhanced control and convenience with the 100e thermostat.

This system was designed to meet the heating needs of the home, offering a sustainable solution that was both efficient and comfortable for all inhabitants.
