Heatrae Sadia 95606988 Titanium Immersion Heater Lower

The Heatrae Sadia 95606988 titanium lower immersion heater is a genuine replacement element designed for use across a wide range of Megaflo unvented cylinders, including Eco, Eco Plus, Slimline, Solar and PV-ready systems.

Installed in the lower section of the cylinder, this element is responsible for heating the full volume of stored water, ensuring consistent hot water availability throughout the system.

Manufactured with a titanium element, this immersion heater offers exceptional resistance to corrosion and aggressive water conditions, making it an ideal choice for long-term reliability in demanding environments. 

🔧 When do you need to replace the lower immersion heater?

You may need to replace this part if:

• Your cylinder is no longer heating fully
• Hot water supply runs out quickly
• Recovery times are slower than normal
• The immersion trips the electrics
• The existing element has failed due to scale or corrosion

As the lower element heats the entire tank, failure will directly impact overall system performance. 

🔬 Why choose a titanium immersion heater?

Titanium elements are designed for maximum durability and corrosion resistance, particularly in systems exposed to:

• Hard or aggressive water conditions
• Solar heating systems
• High-demand hot water usage

Benefits of titanium over standard elements:

• Superior resistance to corrosion
• Longer lifespan in challenging environments
• Ideal for solar and PV-ready Megaflo systems
• Reduced risk of premature failure 

🔥 Titanium vs Incoloy vs Copper – What’s the difference?

Choosing the right immersion heater depends on your system and water conditions:

• Copper elements – Standard option for general use
• Incoloy elements – Improved resistance to limescale in hard water areas
• Titanium elements – Maximum corrosion resistance for demanding or specialist systems

🔁 Upper vs Lower Immersion Heater – What’s the difference?

The lower immersion heater is responsible for:

• Heating the entire cylinder
• Providing the main hot water supply

If your system only heats a small volume of water, the issue may instead lie with the upper immersion heater, which provides boost heating.
