4VT Series Steam Boilers
About the 4VT Steam Boiler
Available in 12 models from 10 to 130 HP, the 4VT range delivers precise, controlled temperatures to a wide variety of applications and equipment, making it an ideal choice for many steam requirements. Hand crafted at our manufacturing facility in Britain and featuring a range of class-leading innovations such as energy-saving four-pass technology and a 30% larger steam chamber, the 4VT Steam Boiler is arguably the most energy efficient, high performance, reliable, and low maintenance steam boiler on the market.
Why you need the 4VT Steam Boiler
- Energy efficient
The 4VT steam boiler is the only boiler in its class to offer four-pass technology for optimum heat transfer, low exit flue temperatures, and minimal running costs this translates to an efficiency of between 92-94 %.
- Superior quality steam
30% larger steam chamber meets variable steam loads efficiently, produces drier steam, reduces scale, and virtually eliminates boiler priming
Fast start up time of 10-15 minutes saves time and energy, and maximises production hours, while Integral heat recovery function minimises cycle times and increases energy efficiency
- Plug and play solution
Skid mounted with optional feed water systems, the 4VT is simple to connect and install
- User-friendly, automatic operation
Controls are fitted at the front of the boiler. Low water level controls with alarms are fitted as standard. Optional microprocessor control
- Reliable, low maintenance design
Durable materials and tubeless construction eliminate blustering, metal stress and refractory problems, and reduces the need for descaling
Compact vertical design makes the 4VT easy to site and install
- Money saving
No NDT test required
- Simple to service
Accessible burner for easy adjustment and servicing, flue way positioned for straightforward cleaning, and central air inlet limits dust or moisture intake
- Meticulously manufactured
Designed and built by CFB Boilers at our manufacturing facility in the UK using over 126 years of steam expertise
- Multiple fuel choice
Gas, Oil or LPG Fired
There are many reasons for requiring a hire boiler. Maybe An existing boiler plant has broken down? A short-term gap between the removal of your old boiler and installation of your new one? Planning a long-term need for extra capacity? Trialling the development of a new product that requires steam or hot water?
Whatever the reason you may need to hire a commercial boilers, or an entire packaged plant, we are the experts to turn to and here’s why:
There are no hidden extras – you will know exactly how much your boiler hire will be, allowing you to carefully manage your budget.
Quick and easy hook up: our industrial boiler hire units include everything required for the boiler to be up and running immediatelyLearn more
Our Design Service specialises in creating Computer-Aided Design (CAD) models. Our highly-trained draftsmen work with engineers, site operatives and customers to design and create 2D and 3D computer models of Boilers, Ancillary Equipment, Layouts of Boiler houses, Plant rooms, Piping Schematics, Wiring Diagrams and much more.
Working to ensure that your chosen equipment will fit into the required space and providing you with full technical information regarding all aspects of your boiler and ancillary equipment.
We also ensure that the equipment provided meets specification criteria and local regulations including Clean Air Act, Medium Combustion Plant Directive, BG01 and more.

Maintenance & Service Contracts
Achieving maximum longevity, performance and efficiency out of your steam boiler system, and eliminating premature repairs and breakdown, is easily and cost-effectively achieved with our planned preventative maintenance services. We also provide service contracts with a minimum 1 yearly contract as it is required by law that your steam boiler must have a yearly inspection.
- Free boiler clean: As part of a standard service, we will strip your boiler down and give it a thorough clean. This is not standard practice in the industry – we go above and beyond in ensuring the long-term performance and reliability of your boiler
- Fixed price service: We offer fixed rate servicing to give you peace of mind and complete cost control
- No unexpected costs: If any additional work is required, we will always conduct a site visit in order to provide an accurate quotation with us there are no hidden or unexpected costs
- Flexible packages: We will tailor a maintenance package to you so that you get the most efficiency and cost-effective service possible
- Convenient and efficient: It is our aim that your business can continue to run without disruption, so any work carried out will be completed in the most efficient way possible by our expert team of engineers

Long-term performance and reliability are built into the very fabric of our boilers, which are designed and engineered to the highest standards. On very rare occasions, or with some older boilers (some of our boilers installed in the 1950s are still going strong!), repair may be required. If it is, you can count on us for a stand-out service:
- Expert response: If a customer calls to report an issue, 99% of the time we can connect them to a trained engineer who may be able to diagnose and even help fix the problem over the telephone
- Fixed rate repair: If an on-site inspection is necessary, we offer a fixed rate repair service that ensures that the boiler is up and running quickly and within budget
- 24 hour repair time: Contract customers benefit from priority status when it comes to operational problem solving and repairs – we will always aim to start the process of repair, or resolve the problem, within 24 hours
Our courses cover all aspects of boiler management which can be taken at your site or at our purpose built workshop here in Essex. We provide users with comprehensive training on their system and ensure they are completely confident to operate it and we are always on hand with any after care advice that’s needed.
Upon completion of course, all candidates will be awarded a certificate in boiler house training.Learn more
If your boiler is in need of de-scaling, we offer acid washes.
This is a two-day process that involves circulating the vessel with acid on day 1 and it’s then left overnight. On day 2 more circulation, checks will be made to ensure the acid has done its job, depending on what kind of scale you have, nearly 9 out of 10 times you are left with a pristine boiler shell.
Common Contributing factors to scale build up:
- In sufficient Water treatment
- No salt in the brine tank
- Incorrect blow down procedures (i.e., not blowing down at all)
- Hard water (area you live in)
Your insurance inspector will check for scale on his inspection. If failed, he will ask you to give it an acid clean.
What will happen
Scale build up on internal pressure side of your boiler can cause adverse problems to the vessel
Cracks can be caused on the boiler shell as a direct result of scale build up.
1mm of scale depreciates your boilers efficiency by 10%
