At Arne Nielsen A/S we stock Ferroli spare parts for a wide range of oil and gas boilers, along with selected boilers from the Ferroli Atlas series — and we make it simple to keep installations running. We hold a large selection of spare parts in stock and top it up continuously, so the shelves stay full. We also keep Atlas-series boilers ready for delivery.
Whether you need a single wear part in the middle of a service call or a complete boiler for a new installation, we can usually dispatch straight away.
A large spare-parts stock — your shortcut to fewer return visits
For a heating engineer or service technician, it is rarely the part itself that costs the most. The real cost is usually the downtime. An installation standing idle while you wait for a spare part is expensive for both you and your customer.
That is why we focus on holding a broad range of Ferroli spare parts in stock — both original and compatible parts: wear and service parts for the boiler types common across the market, along with the components typically replaced during routine service and fault-finding. Just as importantly, we reorder as needed and keep the range up to date as requirements change.
Our Ferroli range covers, among other things:
- Thermostats: operating, hot-water, high-limit and safety thermostats.
- Controls and sensors: weather compensation, outdoor sensors and PT100 sensors.
- Electronics and motors: main circuit boards and fan motors.
- Hydraulics and pressure: circulation pumps, expansion vessels and low-water cut-offs.
- Mechanical parts: draught regulators, gaskets and wear parts.
If you need a specific part you cannot find, call us — and if we cannot supply it from stock, we will get it in quickly.
The result is shorter response times, fewer return visits and a more predictable day for you out on site.
The Atlas series — robust cast-iron boilers in stock
Atlas is Ferroli’s floor-standing cast-iron boiler, built around a robust cast-iron block with three-pass flue technology. The design delivers high efficiency and a solid, long-lasting boiler engineered for many years of service.
Some of the features that make Atlas a popular choice:
- Cast-iron block with three-pass technology for efficient heat transfer and high efficiency.
- High-density rockwool insulation that retains heat and keeps the jacket temperature down.
- Quiet operation thanks to low flue-gas turbulence.
- Conic flue outlet, so the boiler adapts easily to different chimney and flue diameters.
- For oil or gas burner — the boiler body is supplied without a burner and can be combined with a suitable single- or two-stage jet burner to match the job.
For the installer, that translates into a dependable boiler with familiar technology, easy service access and a long service life.
Atlas covers a broad output range and suits both family homes and larger heating duties in commercial and institutional settings. As a heat-only boiler, it is a straightforward, dependable choice where a classic, robust solution is preferred over a compact wall-hung model.
We have boilers from the Atlas series in stock now, and we are happy to advise on model and burner selection so that boiler and burner are matched to the installation.
