Product Information
Full details
This 40-litre stainless steel feed and expansion (F&E) tank from Envy is designed for domestic central heating systems, particularly those with uncontrolled heat sources like solid fuel boilers. Its key benefit is superior durability and resistance to overheating compared to plastic tanks, preventing melting or warping. A potential caveat is its size, requiring adequate installation space. Key features include premium stainless steel construction, a generous 40-litre capacity, dual functionality as both expansion and feed tank, a complete installation kit with a float valve, and a space-efficient cylindrical design.

FAQs
What is the primary advantage of a stainless steel expansion tank over a plastic one?
The primary advantage is its resistance to high temperatures. Unlike plastic tanks, stainless steel will not warp or melt when exposed to prolonged overheated water, making it ideal for systems with uncontrolled heat sources.
What is the maximum system size this tank can support?
This 40-litre tank is suitable for a maximum system size of 717 litres.
Does the tank come with everything needed for installation?
Yes, it includes a brass float valve assembly with a red ball float for automatic water level control.
How do I maintain the water level in the tank?
The included float valve automatically maintains the water level. You should periodically check that the float valve is operating correctly.
What are the physical dimensions of the tank?
The tank has a height of 390mm and a diameter of 455mm.
Can this tank be used for both expansion and as a feed tank?
Yes, it is designed for dual functionality, serving as both an expansion tank to accommodate thermal expansion and a feed tank to maintain system water levels.
Is special maintenance required for the stainless steel construction?
No, the stainless steel is durable and corrosion-resistant. Basic care involves ensuring the float valve works and cleaning with a damp cloth if necessary. Avoid abrasive cleaners.
Troubleshooting
Water level in the tank is too low or too high.
Check the float valve mechanism for obstructions or damage. Ensure the float is free to move and adjust the float arm if necessary, following the manufacturer's instructions.
Leaking from connections.
Ensure all pipework connections are properly tightened. Check that any sealing tape or compound used is appropriate for the application and has been applied correctly.
No water entering the tank automatically.
Verify that the main water supply to the float valve is turned on and that the valve itself is functioning correctly. Inspect for any blockages in the water inlet pipe.
Tank shows signs of external corrosion.
While the stainless steel is resistant, extreme environmental conditions may require additional protective measures or cleaning. Consult a plumbing professional if severe corrosion is observed.
Pros and Cons
Pros
- High durability and corrosion resistance due to stainless steel construction.
- Prevents warping or melting issues common with plastic tanks exposed to high temperatures.
- Accommodates thermal expansion and acts as a water feed for heating systems.
- Includes a float valve for automated water level management.
- Suitable for systems with uncontrolled heat sources like solid fuel boilers.
Cons
- Requires adequate installation space due to its 390mm height and 455mm diameter.
- Installation may require specialized plumbing knowledge.
- Not suitable for environments where extreme external corrosion is a significant factor without appropriate protection.
Setup, Compatibility & Care
Setup: The tank should be installed in accordance with local plumbing regulations and manufacturer guidelines. Ensure connections are secure and leak-free. The float valve assembly should be correctly positioned to allow for free movement of the float and accurate water level control. Multiple connection ports offer flexibility in routing pipework.
Compatibility: This 40-litre tank is designed for use in domestic central heating systems. It is particularly recommended for systems incorporating uncontrolled heat sources such as solid fuel boilers where water temperatures can exceed 100°C. Its maximum system size capacity is 717 litres.
Care: To maintain optimal performance, periodically check the float valve for correct operation and ensure the water level is maintained. The stainless steel construction is inherently low-maintenance; however, occasional cleaning with a damp cloth is sufficient to remove surface dust or dirt. Avoid using abrasive cleaners that could scratch the stainless steel surface.
