Hurst Vertical Boilers

Hurst Vertical Boilers are compact, space-saving, and are offered in tubeless, tubed and hand-fired models. All of Hurst’s Vertical Boilers are highly fuel-efficient, durable, and easy to install and inspect. Hurst also offers Skid-Packaged Boiler Systems for ease of transport and installation.
The 4VT Cyclone Hot Water
This vertical, tubeless hot water boiler is extremely fuel-efficient, due in part to its optimal four-pass design, is shock-proof, ruggedly constructed, compact, and offers easy "eye high" access to its burner. It runs fully automatic, has easy-to-use Solid State controls, and includes low water pressure safety drops.
The 4VT Cyclone Steam
The Cyclone Steam is essentially the steam-boiler equivalent of the Cyclone Hot Water, sharing its fuel-efficiency from four-pass design and many other features. The Cyclone Steam is a high-pressure boiler with exceptionally large steam storage capacity. It handles swing/spike loads well, and has a large steam release surface to minimize condensate/scaling and to achieve calmer operation.
The VIX Series
The VIX Series is a fully-submerged, vertical firetube model with high-efficiency X-ID finned firetubes, and its carbon footprint is less than half that of most vertical boilers. The VIX also has a two-pass design, ultra-efficient heat transfer tubes, all-water-backed exhaust of flue gases, a spacious steam chamber, a water separator that produces dry steam, and water calming/stabilization features.
The VHF Series
VHF (Vertical Hand-Fired) Boilers are hybrids that represent new advances in solid-fuel boiler technology. These units thrive on dense, solid fuels like wood pellets, but they can also be run on coal and other fuels high in BTUs. Both hand-fired and stoker configurations are available, and all units have a modular, "container-shipping friendly," design.
