Are other vertical boilers green with envy?
22 January 2019
We’ve all read the claims, “class-leading”, “energy-efficient”, “superior steam quality”, but do they stack up?

According to Fulton there are really only two vertical tubeless steam boiler solutions available in the UK. One is based on decades-old technology and the other is Fulton’s all-new, double-award-winning VSRT. But how does Fulton’s VSRT-60 compare to equivalent 60HP steam boilers?
Efficiency
With full operating performance curves available throughout the full range of output – and at various operating pressures – Fulton’s VSRT provides exceptionally high operating efficiencies (84% gross thermal efficiency compared to approximately 80% from equivalent models), which result in lower operating costs. Additionally, a Fulton-designed modulating burner and furnace also achieves ultra-low NOx emissions of <20ppm and >10:1 turndown capability.
Steam
At 1,306 litres, the water volume of the VSRT-60 is almost 120% greater than equivalent 60HP boilers yet the VSRT still boasts a start-up time of 10-15 minutes and its installed footprint is up to 25% smaller. The VSRT also achieves a 99.75% steam quality, a figure most manufacturers are unwilling to publish.
Durability
Fulton believes the VSRT will beat the competition in every category of durability, which is why all models come with a 10-year “unparalleled” warranty on the pressure vessel, double that of the industry standard.
Compliance
The VSRT complies with the City of London Air Quality Strategy and anticipated MCPD regulations, is constructed to BS EN 12953 and CE marked to PED.
So, before committing to your next tubeless vertical steam boiler, Fulton urges you to consider the “class-leading” claims about energy efficiency, performance, reliability and maintenance and instead look at the figures that speak for themselves.
