St Andrew’s Church, an 18th‑century landmark in the UK, recently underwent a sensitive heating upgrade that preserves its historic character while delivering modern comfort. Faced with uneven warmth, slow heat‑up times and visual intrusion from the original radiator network, the project team specified an innovative air source heat pump system to replace traditional radiators.
After an international tender, Airosd was chosen for its leading heat pump technology and experience in historic buildings. The proposed solution centers on a modular air source heat pump system, combining three high‑efficiency units with custom controls and renewable integration.
Project Highlights
Heritage‑Sensitive Air Source Heat Pump System Installation
– The new air source heat pump system fit discreetly into existing service voids, avoiding any disturbance to St Andrew’s stone walls or stained‑glass windows.
– Concealed pipework connects to the air source heat pump system and feeds underfloor heating and fan‑coil terminals, replacing bulky radiators without altering the nave’s appearance.
Advanced Heat Pump Technology
– Each air source heat pump system unit draws ambient air and upgrades it to usable heat via inverter‑driven compressors.
– EVI jet‑injection and smart defrost algorithms ensure reliable operation even in sub‑zero conditions, extending the scope of air source heat pump system applications and geothermal heating alternatives.
Smart Controls & Efficiency
– A central controller monitors indoor and outdoor sensors, automatically modulating output for maximum efficiency. This air source heat pump system can adapt to varying attendance patterns—from quiet weekday services to full‑house Sunday worship.
– Integrated BMS compatibility means the air source heat pump system links seamlessly with lighting and ventilation, further reducing energy demand.
Renewable Energy Integration
– To complement the air source heat pump system, rooftop PV panels feed a battery bank. Surplus electricity powers pumps and circulation, minimizing grid reliance and cutting carbon emissions.
– When sunlight is insufficient, the air source heat pump system draws only the necessary grid energy, optimizing life‑cycle costs.
Performance & Comfort
Since commissioning, the air source heat pump system at St Andrew’s has delivered a 40% reduction in heating energy consumption compared to the old radiator network. Thanks to underfloor circuits and fan coils powered by the air source heat pump system, warmth is uniform and responsive—an outcome traditional geothermal heating retrofit approaches could not achieve without extensive excavation.
Why Heat Pump Technology?
– Sustainability: Zero on‑site combustion and up to 5.0 COP (Coefficient of Performance) yield dramatic CO₂ savings.
– Versatility: Whether on frosty winter mornings or mild autumn days, the air source heat pump system adapts output, maintaining a stable interior climate.
– Heritage‑Friendly: Minimal visual impact and non‑invasive installation protect historic fabric.
– Integration: The air source heat pump system can tie into existing building services and smart controls for holistic energy management.
By choosing Airosd’s air source heat pump system, St Andrew’sChurch now combines centuries‑old grandeur with 21st‑century efficiency, setting a benchmark for historic building retrofits across Europe.
