Why Mazzoni Hot Boxes Make All the Difference
At Roundhouse UK, we believe that great results come from a combination of experience, dedication, and the right tools. That’s why we invest in high-performance, eco-conscious equipment, like the Mazzoni Hot Box, a cutting-edge hot water generator that transforms our cold water pressure washers into powerful steam-cleaning machines.
But what does that mean for you, our customer? And why does it matter for the planet?
Let’s take a closer look.
What Is a Mazzoni Hot Box?
Think of it as the engine behind our elite cleaning capabilities.
The Mazzoni Hot Box, also known as the “Firebox” connects to our standard pressure washers, heating water to up to 150°C. This intense heat allows us to tackle jobs that cold water alone simply can’t touch. From stubborn grease and chewing gum to algae, graffiti, and even sanitisation work, this system delivers outstanding results across all types of surfaces.

Why This Benefits Our Customers
✅ Superior Cleaning Power
Hot water cuts through grease, oil, and grime faster and more effectively. Whether we’re restoring a car park or refreshing a building façade, heat-activated cleaning ensures a deeper, longer-lasting clean.
✅ Faster Results = Less Disruption
Because heat accelerates cleaning, we complete projects up to 50% faster than with cold water alone. That means less downtime for your business, reduced access disruption, and faster turnaround times.
✅ A Safer, Healthier Environment
Hot water isn’t just about appearance—it’s also about hygiene. It kills bacteria and viruses more effectively, making it perfect for commercial settings like healthcare, food prep areas, or anywhere public hygiene matters.
✅ Fewer Chemicals = Lower Costs
Thanks to the power of high-temperature cleaning, we can often reduce or eliminate the use of harsh detergents. That’s good news for your budget—and even better news for the planet.
Built for Performance, Designed for Safety
We chose the Mazzoni system because it’s built to last. With stainless steel construction, robust safety features (like flame control, flow switches, and LED alarms), and strict compliance with European emissions standards, it ensures every job is done safely, reliably, and responsibly.
Our equipment handles up to 250 bar pressure and delivers 25 litres per minute, giving us the muscle to clean large surfaces quickly, perfect for car parks, industrial sites, retail properties, and public buildings across York, Harrogate, Leeds, and Ripon.
