Cast iron boiler
Ideal for high temperature applications.
Benefits of natural gas iron boiler
Capable of producing hot water at low or high pressure (up to a maximum of 620kPa), the cast iron boiler maintains water temperature for a long time (120 °C or 248 °F). The natural gas cast iron boiler achieves desired water temperature more quickly and maintains it longer than a steel boiler, thanks to its heaviness and thermal inertia
Reduce your energy costs
Cheaper than fuel-oil - Lower your energy bill by installing a natural gas cast iron boiler. Not only is natural gas more powerful than fuel-oil, it also costs less.
Consume less, spend less - With energy efficiency as high as 95%, a condensing boiler can generate substantial savings while improving performance! It’s the ideal solution when energy efficiency is a must, as in LEEDS projects, for example.
Choose performance
The advantage of the natural gas cast iron boiler is its ability to heat water to extremely high temperatures. Cast iron has excellent thermal conductivity and is highly resistant to corrosion.
