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 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 Installation – The new 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 underfloor heating and fan‑coil terminals, replacing bulky radiators without altering the nave’s appearance. Advanced Heat Pump Technology – Each air source heat pump 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 geothermal heating alternatives. Smart Controls & Efficiency – A central controller monitors indoor and outdoor sensors, automatically modulating output for maximum efficiency. This 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, 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 heat pump system draws only the necessary grid energy, optimizing life‑cycle costs. Performance & Comfort Since commissioning, St Andrew’s has seen a 40% reduction in heating energy consumption compared to the old radiator network. Thanks to underfloor circuits and fan coils, 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 adapts output, maintaining a stable interior climate. – Heritage‑Friendly: Minimal visual impact and non‑invasive installation protect historic fabric. By choosing Airosd’s air source heat pump system, St Andrew’s Church now combines centuries‑old grandeur with 21st‑century efficiency, setting a benchmark for historic building retrofits across Europe.

Heat pump efficiency hinges on proper use and care. Avoid extreme thermostat changes, skipped filter or heat‑exchanger cleaning, blocked outdoor units, unauthorized refrigerant handling, continuous full‑load operation, placement in damp areas, uninsulated piping, frequent full power‑cycling, and ignoring manuals or warranties. Mindful operation protects your initial heat pump installation cost and minimizes future heat pump replacement cost, whether for air source heat pump installation or geothermal heating and cooling.

Air and water source heat pumps offer efficient cooling, heating, and hot water. From air to air to water to water geothermal systems, each fits unique needs for sustainable comfort year-round.

AIROSD, the only invited heat pump manufacturer from Foshan, showcased its dryer heat pump, heating cooling and hot water, and swimming pool heat pump solutions at the China–ASEAN trade summit, promoting green energy.

AIROSD’s air source heat pump provides reliable heating in Xinjiang’s harsh climate of cold, sandstorms, and temperature swings. Using four technologies—EVI ultra-low-temp heating to −40 °C, AI-driven defrosting, V-type evaporator for sand resistance, and AI smart control—AIROSD ensures stable, efficient heating. Installed in 120 + public buildings, it champions green heating in high-cold areas.
