Water Heater Replacement in Luxembourg – Tank vs Tankless Guide

Water Heater Replacement Guide for Luxembourg

If your water heater is over 10 years old, it's time to consider replacement before it fails — usually at the worst possible moment.

Tank vs Tankless — Which is Better?

| Feature | Tank (Boiler) | Tankless (Instantaneous) | |---------|-------------|------------------------| | Hot water supply | Limited by tank size | Unlimited | | Energy efficiency | 60–70% | 90–98% | | Space needed | Large (150–300L tank) | Wall-mounted, compact | | Installation cost | €800–€1,500 | €1,500–€3,000 | | Running cost/year | €400–€600 | €200–€350 | | Lifespan | 10–15 years | 15–20 years |

When to Choose a Tank Water Heater

• Multiple bathrooms needing hot water simultaneously
• Lower upfront budget
• Replacing an existing tank system (simpler swap)

When to Choose Tankless

• Small apartment with limited space
• Energy efficiency is a priority
• You want unlimited hot water
• Long-term cost savings matter
