Yorkshire and the Humber
Overview
Thermodynamics South Yorkshire installed a Riello air source heat pump and full central heating system in a cottage with solid stone walls and no existing central heating in place. Portable electric radiators were used as primary heating.
The property is a stone built 1800’s cottage, converted from a factory building with a long history of vinegar production. The property is next to a canal and the heat pump needed to be sited on the side wall facing the canal so the customer’s boat was used as a platform to work from.
Challenges
The property has 450mm thick solid stone walls with no insulation and the survey calculations established a 8962w heat loss, requiring a 10kw heat pump. As the property had no existing central heating system in place and the central heating system was designed to be open loop and not use hydraulic separation, the challenge faced was installing the appropriately sized pipework through 3” joists covered with multiple layers of floor boards and plywood without weakening the structural integrity of the floors.
Due to the property having external walls buried to the back of the property these walls required the external temperatures to be calculated at the average ground temperature rather than the external average lowest air temperatures which positively impacted the heat loss of the affected rooms.
Costs
The total installation price was £13,817.
