Description:
VIADRUS U22 heating boilers are made of cast iron sections that are pressed together and anchored with through-bolts.
This is a tried and tested technique that ensures a very long service life for your heating boiler.
Chimney-sweeps, plumbers and the entire HVAC sector are in agreement about the superior properties of cast iron heating boilers. This is because of cast iron’s high torsional rigidity and resistance to corrosion (rust).
By way of comparison, nobody would come up with the idea of manufacturing a car engine out of normal welded sheet metal.
The Viadrus Hercules U22 is a perfect heating boiler for all houses and small apartment blocks. Over the years, more than 200,000 satisfied customers across Europe have purchased this cast iron boiler. A U22 cast iron boiler places low demands on your chimney. It works both in pump-based systems with a charging unit (this is the standard solution) and in systems employing self-circulation, and is very easy to use. It is simple to load the heating boiler with large chunks of wood thanks to the large hatch, a feature that is appreciated by many of our satisfied customers. You are recommended to position a Viadrus heating boiler on a stand or base, approximately 500 mm in height. Also bear in mind that a heating boiler should be positioned a safe distance from easily flammable materials.
- Lower demands placed on the chimney than is the case with many heating boilers
- Potential to burn wood with a moisture level of up to 20%
- The boilers are available in several sizes, and the number of sections controls the output
- A service life of 50 years is common for a cast iron boiler (A normal heating boiler made of welded sheet metal can rust out in less than 8 years).
- Can withstand approximately 100% higher pressure than heating boilers made of welded sheet metal.
- No electronics or ceramics that can cause problems.
- Can also easily be converted to a pellet boiler with our pellet burners
