RGL Services delivers industrial boiler cleaning and economiser cleaning across the UK using ultra-high-pressure water jetting at up to 2,800 bar. Operating since 1984, we remove scale, soot, ash and fused deposits from boiler tubes, economiser surfaces and furnaces to restore heat transfer, lower fuel costs and prevent downtime. Our water-only method works on fire-tube and water-tube boilers across power generation, manufacturing and industrial sites.
As specialist boiler cleaning contractors, we developed UHP systems that deploy rapidly in almost any industrial environment, for emergency response and scheduled maintenance alike. Rentajet offers nationwide cover with Romsey, London and Manchester support and a direct response service for outages and urgent requirements.
When boiler tubes, economiser surfaces and furnaces become choked with scale, soot, ash or fused deposits, heat transfer is severely restricted. The boiler works harder to hold output, fuel consumption rises sharply, and the risk of overheating, tube stress and unplanned downtime grows. Fouling is in effect an insulating barrier between the fire side and the water side.
Ultra-high-pressure water jetting at 2,800 bar removes even the hardest ash and fused deposits from fire-tube and water-tube boilers without chemicals, restoring heat transfer surfaces and efficient operation. The process is fast, contained and chemical-free, which suits both emergency restoration and scheduled cleaning as part of a routine maintenance programme.
That combination is what gets UHP boiler cleaning and economiser cleaning specified on critical plant where lost efficiency, fuel cost and downtime risk all carry a direct and growing penalty.
Rentajet operates a full range of UHP boiler cleaning services configured to the boiler type, the deposit and the access on site.
Boiler tube cleaning of fire-tube and water-tube boilers to remove scale, soot and fused deposits, restoring heat transfer on both the fire side and the water side.
Economiser cleaning removing ash and fused deposits from economiser surfaces, where fouling commonly restricts flue-gas heat recovery and raises stack temperature.
High-pressure water jetting of furnace ceilings and walls to clear deposits and blockages that restrict combustion and heat transfer.
Boiler and economiser cleaning scheduled into planned outages and shutdowns, sequenced to minimise the off-line window.
Rapid-response cleaning to restore a fouled boiler that is limiting output or efficiency between planned outages, with 24/7 attendance across the UK.
Routine boiler tube cleaning and economiser cleaning under planned maintenance programmes to keep efficiency consistent and prevent the build-up of fused deposits.
UHP boiler tube cleaning changes the efficiency, cost and reliability profile of boiler maintenance compared with mechanical and chemical methods.
Heat transfer surfaces are returned to efficient operation, recovering output and lowering fuel use.
UHP jetting clears fused ash and hard scale that mechanical methods struggle to shift.
Uses only water, with no chemicals to handle, neutralise or dispose of.
Clean surfaces transfer heat efficiently, cutting fuel consumption and operating cost.
Regular cleaning prevents the overheating, tube stress and unplanned outages that fouling causes.
Removing deposits reduces under-deposit corrosion and thermal stress, extending boiler life.
Mechanical de-scaling and chemical cleaning remain common where specialist water jetting is not available. They are familiar but bring chemical handling and waste, risk of tube damage, and often incomplete removal of fused deposits. UHP water jetting carries an equipment day rate but removes the chemical burden and the tube-damage risk, which on most boiler scopes makes it the lower total cost route.
| Factor | UHP Water Jetting | Mechanical / Chemical Cleaning |
|---|---|---|
| Fused ash and hard deposits | Removed completely | Often partial |
| Tube damage risk | None, no abrasion | Possible wear or thinning |
| Chemicals used | None, water only | Often required, with neutralising |
| Fire side and water side | Both cleaned | Limited by method |
| Waste handling | Contained wastewater | Chemical or contaminated waste |
| Downtime | Minimal, fast cleaning | Extended by dwell or rodding |
| Efficiency recovery | Near-original heat transfer | Partial |
| Emergency response | 24/7 UK attendance | Often slower to mobilise |
UHP boiler and economiser cleaning is specified wherever fouling is restricting heat transfer and raising fuel cost. Rentajet delivers across three primary application sectors.
Boiler tube, economiser and furnace cleaning on coal, gas, biomass and Energy-from-Waste plants during outages, restoring heat rate and efficiency.
Fire-tube and water-tube boiler cleaning in manufacturing and process plants where steam supply and fuel cost depend on efficient heat transfer.
Cleaning of economiser and heat-recovery surfaces where ash fouling restricts flue-gas heat recovery and raises stack temperature.
Rentajet delivers economiser cleaning and boiler cleaning to UK operators across the sectors most reliant on efficient steam and heat.
Boiler, economiser and furnace cleaning on coal, gas, biomass and Energy-from-Waste plants during planned and emergency outages.
Process boiler and heat-recovery cleaning on refineries and chemical plants where steam efficiency affects operating cost.
Boiler and economiser cleaning in food and beverage production where steam supply and fuel cost are critical to the process.
Boiler cleaning to maintain steam efficiency and reduce fuel cost in chemical and paint manufacturing plants.
Boiler and furnace cleaning on heavy manufacturing and industrial sites where heat transfer efficiency affects production.
Cleaning of boilers and economisers ahead of inspection, decommissioning or recovery on end-of-life plant.
RGL Services has been delivering water jetting services to UK heavy industry since 1984 and has developed UHP systems that deploy rapidly in almost any industrial environment, for emergency response and scheduled maintenance alike.
Boiler and economiser cleaning sits inside a wider water jetting capability that includes heat exchanger and tube bundle cleaning, pipeline cleaning and blockage removal and tank, vessel and column cleaning, which means cleaning teams arrive with the full scope of supporting services on the same mobilisation.
• Forty years of UHP water jetting experience: established 1984, with delivery across UK drainage, sewer and flood-prevention systems.
• Precision in-pipe cutting: purpose-built rigs that cut concrete, piles and debris in pipes from 95mm upwards without excavation.
• ISO 9001, ISO 14001 and ISO 45001 registered: Water Jetting Association membership and full adherence to the WJA Code of Practice.
• Bespoke rig engineering: custom tooling designed to the site conditions and obstruction type on complex projects.
• UK-wide mobilisation: Romsey HQ with London and Manchester support, and a direct response service for blocked critical systems.
The result is a contractor that plant, reliability and energy managers can specify with confidence on boiler cleaning scopes where efficiency, fuel cost and uptime all matter.
Rentajet follows a five-step process on every boiler cleaning mobilisation, from initial enquiry through to performance handover.
We survey the boiler, the deposit type, the access and the outage window, and confirm the cleaning method for tubes, economiser and furnace. A method statement and risk assessment are produced covering water management and WJA Code of Practice compliance.
UHP pumps, lances, rotating heads and recovery plant are mobilised to site. Pump units run at up to 2,800 bar, with all hoses and connections inspected under WJA Code of Practice.
Lances and heads are configured to the tube and surface type. Pressure and traverse are set and confirmed before bulk cleaning starts.
Tubes, economiser surfaces and furnace areas are cleaned to remove scale, soot, ash and fused deposits while wastewater and debris are contained and recovered. Cleanliness is checked against the specification.
The cleaned boiler is inspected, a record is issued, and the plant is handed back ready to return to service at restored efficiency.
Cost depends on the boiler type and size, the deposit, the access and the outage window. UHP water jetting carries an equipment day rate but typically pays back quickly through restored efficiency and lower fuel cost, and by avoiding the downtime that fouling causes.

Yes. Ultra-high-pressure water jetting at 2,800 bar removes even the hardest fused ash and scale from fire-tube and water-tube boilers, which is one of the main reasons it is specified over mechanical de-scaling. Pressure and tooling are matched to the surface.
No. Water jetting removes deposits through water pressure without the wear or thinning that mechanical rodding can cause. Settings are matched to the tube specification and confirmed before bulk cleaning.
Yes. We provide 24/7 all-year-round site attendance across the UK for emergency restoration of a fouled boiler that is limiting output, as well as scheduled cleaning within planned outages.
Yes. We clean boiler tubes, economiser surfaces and furnace walls and ceilings, since fouling on any of these restricts heat transfer. The survey confirms which surfaces need cleaning and the best method for each.
