Calorifier Ancillary Equipment

For safe and compliant operation of unvented commercial calorifiers, World Heat Cylinders offers comprehensive unvented system kits and individual components. Specifically, these kits are meticulously specified to integrate seamlessly with our large commercial calorifier range, thereby ensuring optimal performance and adherence to UK regulations, including G3 Building Regulations.

Our standard unvented kits typically include:

• Inlet Control Group: Comprising a pressure reducing valve (PRV), strainer, check valve, and balance cold water take-off. PRVs are available for various pressure requirements and connection sizes up to 6".
• Expansion Vessel: To accommodate the expansion of heated water. We supply expansion vessels correctly sized for systems up to 3,000 litres and beyond, crucial for preventing overpressure.
• Temperature & Pressure Relief Valve (T&P Valve): An essential safety device to release excess temperature or pressure.
• Tundish: To provide a visible discharge point from safety valves.

Consequently, by choosing World Heat Cylinders' unvented component kits, you benefit from:

• Guaranteed Compatibility: Components are selected to work flawlessly with your chosen calorifier.
• Regulatory Compliance: In addition, all parts meet relevant UK standards for safety and performance.
• Simplified Specification: Furthermore, you save time by specifying a complete, proven kit.
• Quality Assurance: Crucially, we provide durable, high-quality components for long-lasting reliability.

Moreover, we can also supply individual unvented components to suit your specific project requirements. Therefore, contact our technical team to discuss your calorifier system design.

To facilitate essential routine maintenance, cleaning, and inspection, World Heat Cylinders offers robust inspection openings for our calorifier ranges. Indeed, these access points are crucial for prolonging the life of the calorifier, ensuring optimal performance, and also assisting with compliance for Legionella control (as per ACoP L8 guidelines).

Our inspection openings typically feature:

• Durable Construction: Manufactured from materials compatible with the calorifier shell for longevity.
• Secure Sealing: High-quality gaskets and bolted flanges (for manways) to ensure a watertight seal.
• Variety of Sizes: Standard inspection manways and handholes are available with common diameters such as 250mm, 350mm, and 450mm, suitable for various calorifier capacities and access requirements. Bespoke sizes can also be accommodated.

Specifically, benefits of incorporating appropriately sized inspection openings include:

• Simplified Maintenance: Easier access for cleaning scale build-up and sediment.
• Thorough Inspections: Furthermore, this allows for visual inspection of internal surfaces and components like coils.
• Enhanced Safety: Importantly, it supports water quality management and Legionella risk assessment.

Therefore, specify inspection openings on your WH Cylinder calorifier to ensure ease of service throughout its operational life.

Thermal stratification within a calorifier – where layers of water at different temperatures form – can, for instance, lead to reduced energy efficiency and subsequently create potential breeding grounds for Legionella bacteria in cooler, stagnant zones. However, World Heat Cylinders offers pre-plumbed de-stratification pump sets designed to counteract this issue effectively.

Essentially, our de-stratification pump sets work by:

• Actively Circulating Water: The pump gently circulates water within the calorifier, mixing the layers to achieve a more uniform temperature throughout the stored volume.
• Eliminating Cold Spots: As a result, this circulation prevents the formation of cold spots at the base of the cylinder, which can be a prime area for bacterial growth.
• Improving Energy Efficiency: Furthermore, by maintaining a consistent temperature, the primary heat source can operate more efficiently, and hot water delivery is more predictable.

Key benefits of installing a World Heat Cylinders de-stratification pump set include, for example:

• Even Stored Temperature: Moving hot water from the top of the calorifier to the base reduces cooler zones, a design feature that can help a Legionella control regime set by the site's risk assessment (see the HSE's ACoP L8 and HSG274).
• Increased System Efficiency: Additionally, it reduces energy waste associated with stratified water.
• Improved Hot Water Availability: Moreover, this ensures more of the stored water is at the desired temperature.
• Pre-Plumbed Convenience: Finally, it is supplied as a ready-to-install unit for ease of fitting and reduced site time.

In conclusion, our de-stratification pump sets are suitable for a wide range of commercial calorifiers. Therefore, discuss your system requirements with our team to ensure the correct specification for your application.
