Arca Caldaie supplier in Romania
Italian industrial boilers for heating and process applications
Founded in 1990 · Headquarters: San Giorgio Bigarello (Mantua), Italy
Who is Arca Caldaie and what does it make?
Arca Caldaie is an Italian manufacturer of boilers and heating systems, headquartered in San Giorgio Bigarello, in the province of Mantua, active since 1990. The range covers wall-hung gas boilers, biomass boilers (wood or pellets), hybrid systems that combine a boiler with a heat pump, hot air generators and pellet stoves. From the Arca Caldaie portfolio we can quote heating equipment for civil buildings and for industrial processes with a heat demand.
The company covers several combustion and heating technologies under the same brand — from classic natural gas boilers, through solid fuel boilers for areas without mains gas, to hybrid systems designed to reduce fossil fuel consumption by combining with a heat pump. The range also includes solar thermal and photovoltaic panels for combined installations.
For buildings in Romania without access to mains gas, or for installations that want to reduce dependence on a single fuel, the Arca Caldaie range of biomass boilers and hybrid systems can complement an existing installation or be the basis of a new one, in civil buildings or small to medium industrial spaces.
What do we supply from the Arca Caldaie range?
| Product | Description |
|---|---|
| Wall-Hung Gas Boilers | Wall-hung natural gas boilers for heating and, depending on the model, domestic hot water production, designed for installation in civil buildings or small commercial spaces. Compact construction, suited to new installations or to replacing an old boiler without modifying the existing installation. Typical application: heating an office building or a commercial space with moderate heat demand. The customer states the power needed and the type of installation. |
| Biomass Boilers (Wood/Pellets) | Solid fuel boilers for heating buildings without access to mains gas, with manual feeding of firewood or automatic feeding of pellets from a hopper. They reduce dependence on a single type of fuel and can be combined with buffer tanks to manage consumption peaks. Typical application: rural buildings, farms, small halls without a gas connection. The customer states the power needed, the heated area and the fuel available locally. |
| Hybrid Boiler + Heat Pump Systems | Systems that combine a classic gas boiler with a heat pump, in which the wall-hung condensing boiler manages the installation and the heat storage is fed by a renewable source (solar thermal, heat pump or biomass boiler), according to the manufacturer's description of the Sistema SUN. The customer states the heated area and the type of existing installation. |

How do we supply Arca Caldaie in Romania?
For Arca Caldaie we work from the technical documentation of the Italian manufacturer — we state plainly what we confirm for each model. Boilers and components are sourced to order through EU supply channels, usually in 1–4 weeks from order confirmation. For a quotation we need the power required, the type of fuel available and whether the installation is new or replaces an existing boiler. Availability depends on the range and on the season, and we confirm it for each model in the quotation.
Spare parts for older models, since withdrawn from current production, are checked case by case, on request.
Frequently asked questions about Arca Caldaie
What types of boilers does Arca Caldaie make?
Arca Caldaie makes wall-hung gas boilers from the Pixel range, biomass boilers using wood or pellets, hybrid systems with renewable sources (of the Sistema SUN type) and industrial steel boilers for larger installations. The range also includes water heaters, storage tanks and heat pump air-conditioning systems for complete heating projects.
What is the Sistema SUN hybrid system from Arca Caldaie?
Sistema SUN is a wall-hung condensing boiler with premixed combustion, equipped with a control and management system for heat storage produced with solar thermal, a heat pump or a biomass boiler. The boiler manages the installation, and the storage is heated only by the renewable source.
Do you supply Arca Caldaie equipment in Romania?
Yes, Arca Caldaie equipment arrives to order, usually in 1–4 weeks; we source this range project by project, on the basis of the exact model requested from the manufacturer's catalogue. We recommend stating the thermal power needed and the fuel type wanted, gas, biomass or hybrid system, for a correct quotation.
What is the difference between a gas boiler and a hybrid system from Arca Caldaie?
The gas boiler from the Pixel or Pixelfast range produces heating water solely by burning natural gas, while hybrid systems, such as Sistema SUN, manage the storage of heat produced from renewable sources (solar thermal, heat pump or biomass). The choice depends on the available budget, the solar exposure of the building and the aim of reducing the energy bill.
