Mounting of oil nozzle

Annual nozzle replacement and why it’s important for oil boiler performance

Avatar for Lisa HimicsLisa Himics

The Crucial Role of a Nozzle in an Oil Boiler

Oil boilers depend on a precise system of components to deliver heat efficiently, and one of the most critical parts is the nozzle. Its main job is to atomise the fuel — breaking it into fine droplets that allow for cleaner, more efficient combustion.

Key factors such as the nozzle’s spray pattern, angle, flow rate, and droplet size all determine how effectively the fuel mixes with air. A well-functioning nozzle helps maintain flame stability, reduces soot build-up, prevents harmful emissions, and improves overall energy efficiency.

However, when a nozzle becomes clogged or worn, the results can be costly: poor combustion, higher fuel bills, and even damage to the boiler. That’s why it’s essential to follow the manufacturer’s guidance and replace the nozzle annually. Regular servicing and inspections ensure your boiler continues to run safely, efficiently, and reliably.

Danfoss Oil Nozzles: Service and Replacement

At EOGB, we supply a wide range of heating spares, with Danfoss nozzles holding a key position. Known for their quality and precision, Danfoss is a trusted name when it comes to reliable, high-performing oil nozzles.

The Danfoss range is designed to suit a variety of burner systems, offering different spray patterns and angles to meet the unique demands of each application.

From their expert perspective, Danfoss strongly recommends replacing the oil burner nozzle once a year. This is not just a suggestion but a proactive step that delivers several important benefits: improved operating performance, enhanced reliability, lower heating costs, and reduced environmental impact.

Symptoms of a failing nozzle can include a noisy burner, sooty flames, reduced heating efficiency, or the boiler failing to ignite properly. Annual replacement is the best preventative measure.

“It is essential that you keep your oil fired boiler serviced to optimize efficiency, reliability and safety of your system. Replacing the nozzle is a hugely important part of the service and will ensure the best possible performance and also help keep emissions to a minimum”.

Stephen McElroy, Danfoss Key Account Manager Burner Components

What information should I look for when buying a replacement Danfoss nozzle?

Manufacturers design each nozzle with precise characteristics, and even small variations can affect combustion quality. If you order nozzles at EOGB, our Sales team will make sure you choose the right one for your burner.

The key details you should check are:

Spray angle: Affects how the fuel is distributed within the combustion chamber and must match your burner’s design (30 °, 45 °, 60 °, 80 °).

Flow rate Spray pattern: Ensures proper fuel-air mixing and efficient combustion for your specific burner type. (H, S, EH, ES, B).

Imagine you’re using a Danfoss 0.60 GPH 60°S nozzle. The 60° angle means the fuel spray is distributed in a medium-wide cone, suited for most standard combustion chambers. The 0.60 GPH figure indicates the nozzle delivers 0.60 gallons of fuel per hour at a set pressure (usually 7 bar/100 psi). The “S” stands for Solid spray, which evenly distributes fuel across the spray cone — ideal for certain chamber designs.

Bear in mind that throughputs differ between S and H gas oil nozzles compared to EH and ES kerosene nozzles. Always check the boiler data to ensure you are using the correct nozzle for the application.

“Danfoss Nozzles come in many patterns and sizes. The most common nozzles among EOGB customers are the 0.60 x 60ES and 0.75 x 80EH. The E before the S or H spray pattern stands for Enhanced for Kerosene applications. This means it has been calibrated with Kerosene, predominantly the most common domestic heating fuel in the UK. ES/EH Nozzle begin at 0.40Usgal – 1.10Usgal. The reason they don’t make Kerosene Enhanced nozzles past the 1.10-gallon size is because not many domestic properties running on Kerosene will require a larger output than 40kW and above”.

Dispelling Myths About Modulating Oil Boilers

Avatar for Lisa HimicsLisa Himics

The Benefits of Sapphire Heat Solutions fully modulating range

In the world of heating technology, particularly with oil boilers, there are many misconceptions about the effectiveness and benefits of modulating systems compared to traditional on/off models. Martin Cooke, owner and managing director of EOGB Energy Products Ltd and Sapphire Heat Solutions, discusses the current landscape of the modulating boiler market, emphasizing the growing demand for more efficient and environmentally friendly heating solutions. He highlights that as homeowners become increasingly aware of energy costs and environmental impact, the shift towards modulating systems like those offered by Sapphire is not just a trend but a necessary evolution in the industry. 

Sapphire Heat Solutions has developed innovative fully modulating Opentherm oil boilers that challenge these myths and offer significant advantages for homeowners, particularly for the Combi version that will be launched in January 2026. Let’s take a closer look at some common misconceptions and the reality behind Sapphire’s technology. 

Myth 1: Modulating Oil Boilers Are Not Worth the Investment 

Reality: 

Independent Testing Results: Recent data from Notified Test Houses showed that Sapphire’s modulating oil boilers achieved savings of 15% in fuel consumption compared to a leading condensing boiler model using an on/off burner, which interestingly has the same test house data efficiency rating, confirming that modulation improves overall system efficiency considerably. This data is supported by anecdotal evidence from satisfied customers, all backed up by stringent independent lab testing. This demonstrates the superior efficiency of Sapphire’s technology in real-world conditions. 

Long-Term Savings: While the initial cost of a modulating oil boiler like Sapphire may be higher than traditional models, the long-term savings on fuel can quickly offset this. Multiple Sapphire customers claim that their systems can reduce oil consumption by at least one tank fill per year, translating to approximately 1,000 litres of oil saved annually. Given the current price of kerosene, this can result in savings of around £550 or more each year.

Proven Performance, Trusted by Homeowners

“Upgrading existing boiler and heating control has improved the energy performance of the building from Band A to Band A. Our new energy-efficient boiler works on HVO and we often forget that we’re no longer using kerosene.”

Matthew Thompson & Emma Freeman

Marginal Cost vs. Savings: The initial extra marginal cost of the Sapphire oil boiler fades into insignificance when you consider the substantial annual savings. This makes it the only oil boiler on the market that truly provides a return on investment. Homeowners can expect to recoup their investment in a short period through consistent savings on heating costs. 

Energy Efficiency: Sapphire’s modulating technology allows the boiler to adjust its output based on real-time heating demands. Traditional oil boilers often overshoot on temperature, wasting energy and leading to inefficient operation. In contrast, Sapphire’s unique modulation reduces overshoot by maintaining a steady temperature. Once the desired setpoint is achieved, the boiler modulates to low power rather than cycling on and off, which not only improves efficiency but also reduces wear and tear on critical components. This is important because there’s a reason why the gas industry uses modulation as a standard practice both domestically and commercially, oil boilers were more complex to modulate initially before the technology was perfected, which is why the industry has been slower to evolve in this area. 

Higher Water Content: Sapphire boilers have a similar water content compared to other oil boilers of similar output, yet they achieve a higher overall system efficiency. This dispels the myth that modulation is only suitable for lower water content boilers, demonstrating that Sapphire’s boiler design enhances performance without compromising efficiency. In fact, in the early days of the Sapphire burner development, it was fitted to a number of leading manufacturers’ heat exchangers with great results, showing that boiler manufacturers don’t necessarily need to redevelop their heat exchangers to accommodate modulating burners, although return temps need to be observed. 

One-Piece Fire Tube Heat Exchanger: Sapphire’s innovative design includes a one-piece fire tube heat exchanger that offers significant advantages over commonly used primary and secondary oil boiler designs. This construction minimizes the risk of leaks and enhances thermal efficiency, making Sapphire boilers a superior choice for homeowners.

OpenTherm Technology: Sapphire is the only oil boiler in the marketplace that uses OpenTherm technology. This advanced feature enhances communication between the boiler and the heating controls, allowing for more precise modulation and control of heating outputs. This results in improved comfort, efficiency, and further energy savings. 

Myth 2: Modulating Systems Are Too Complicated 

Reality: 

User-Friendly Technology: Sapphire’s fully modulating oil boilers are designed with user-friendliness in mind. Sapphire is fully compatible with advanced controls, such as smart thermostats and remote monitoring capabilities, allowing homeowners to easily adjust settings and monitor energy usage from anywhere. From a service and commissioning point of view our installers once experienced, don’t have any issues compared to any other boilers in the marketplace. The fact that the Sapphire boiler has no baffles to remove and only one heat exchanger makes the whole service process far easier and cleaner than many other boilers, no more sooty baffles lying in the customer’s kitchen! 

Myth 3: Modulating Boilers don’t help towards Net zero 

Reality: 

Lower Emissions: By operating more efficiently and modulating only to the requirements of the system, Sapphire’s modulating oil boilers contribute to reduced CO2 emissions. The system can lower greenhouse gas emissions significantly, which reduces the environmental impact compared to traditional boilers. Additionally, the incorporation of renewable HVO (Hydrotreated Vegetable Oil) or a blend of kerosene and HVO also significantly decreases the carbon intensity of the system. This aligns with the net zero targets set by governments and environmental initiatives. 

The Benefits of Stainless Steel Heat Exchangers 

A crucial feature of Sapphire’s fully modulating oil boilers is the use of stainless steel heat exchangers, which offer several advantages over standard mild steel options: 

Reduced Corrosion: Stainless steel is inherently more resistant to corrosion, especially in low-temperature return applications. This is crucial because standard mild steel boilers often suffer from corrosion due to condensation and low-temperature returns and dirty system water, leading to costly repairs and shorter lifespans. The use of stainless steel helps mitigate these issues, enhancing durability. The Sapphire boiler proudly offers a 25 year warranty on the heat exchanger! 

Longevity: The resistance to corrosion translates into a longer lifespan for the heating system. Homeowners can expect fewer replacements, resulting in lower overall costs and less environmental impact associated with manufacturing and disposing of heating equipment. 

Conclusion 

The myths surrounding modulating oil boilers, particularly those related to Sapphire Heat Solutions, often stem from a lack of understanding about the technology and its benefits. By investing in a Sapphire fully modulating oil boiler, homeowners can enjoy long-term savings, improved comfort, and a more environmentally friendly heating solution. With high efficiency ratings, significant cost savings, advanced stainless steel heat exchangers, and a commitment to reducing emissions, Sapphire’s technology represents a smart choice for modern heating needs. It’s time to look beyond the misconceptions and embrace the innovative technology that Sapphire offers for a more efficient and comfortable home heating experience.
