What Is a Side Entry Immersion Heater?
A side entry immersion heater is fitted horizontally into the side of a hot water cylinder rather than vertically from the top. These are very common in older hot water tanks throughout Dublin homes and apartments.
Common signs your side entry immersion heater needs replacement include:
- No hot water
- Water only heating partially
- Burning smell from immersion
- Immersion tripping power
- Leaking from the element
- Noisy or scaled-up immersion heater
- Slow heating times
- Thermostat failure
We carry common side entry immersion heater sizes and parts for same-day replacement in many cases.

Standard Copper or Incoloy Immersion?
Standard copper immersion elements are suitable for many domestic hot water systems. However, in hard water areas, limescale can shorten the lifespan of a standard element and reduce heating efficiency.
Incoloy immersion elements are designed to offer better resistance to limescale build-up and are usually the better option for homes in hard water areas throughout Dublin.
We can advise on the most suitable replacement when inspecting your existing hot water cylinder and immersion setup.

Common Side Entry Immersion Heater Problems
Immersion Heater Not Working
A failed immersion element or faulty thermostat is one of the most common causes of no hot water.
Immersion Tripping Electricity
This usually indicates an internal fault in the element allowing moisture ingress or insulation breakdown.
Leaking Side Entry Immersion
Older immersion fittings can corrode or fail over time, leading to leaks around the tank connection.
Hard Water Damage
Limescale build-up can reduce efficiency and shorten immersion heater lifespan. Incoloy elements are recommended for these systems.
Slow Heating Times
Scaled-up or failing elements can take much longer to heat your cylinder, increasing running costs.
Thermostat Failure
A faulty thermostat can cause overheating, intermittent heating, or no hot water from the immersion.
