Leaking Hot Water Cylinder? Repair vs. Replacement Guide – Laser Plumbing Wellington East
A leaking hot water cylinder can be a major inconvenience, potentially causing water damage and increasing energy bills. When faced with this issue, homeowners must decide whether to repair the existing cylinder or invest in a new one. The right choice depends on the extent of the damage, the age of the cylinder, and your long-term hot water needs.
At Laser Plumbing Wellington East, we specialize in hot water cylinder repairs and replacements, helping homeowners make the best choice for efficiency and cost savings. Here’s a detailed breakdown to guide your decision.
How Bad Is the Damage? Assessing Your Hot Water Cylinder
Before deciding between repair or replacement, inspect the location and severity of the leak:
Small Leaks (Fixable Issues) – If the leak comes from a valve, pipe connection, or seal, it may be repairable without replacing the entire system.
Major Leaks (Replacement Likely Required) – If water is leaking from the body of the tank, corrosion may be the cause, meaning replacement is the safest option.
Key Factors to Consider
Age of the Cylinder – Older cylinders (10+ years) are more prone to corrosion and wear, making replacement a better long-term solution.
Rust and Corrosion – Visible rust or a metallic taste in your water indicates deterioration inside the tank, which often requires replacement.
Water Heating Efficiency – If your cylinder struggles to maintain hot water supply or causes high energy bills, upgrading to a modern, energy-efficient model may save money in the long run.
Repair vs. Replacement: What’s More Cost-Effective?
Cost of Repairing a Leaking Hot Water Cylinder
Repairing a minor leak is generally cheaper than installing a new unit. Common fixes include:
Replacing faulty valves, seals, or thermostats
Fixing leaks from pipe connections
Repairing minor damage to external components
However, if repairs become frequent, the cost adds up, making replacement a better long-term investment.
Cost of Replacing a Hot Water Cylinder
A new hot water cylinder has a higher upfront cost but offers:
Lower energy bills with high-efficiency models
Long-term reliability (new cylinders last 10-20 years)
Better water heating performance
Did you know? Upgrading to a heat pump water heater or a modern electric system can significantly reduce your household’s energy costs.
Choosing the Best Hot Water Cylinder for Your Home
When replacing your hot water cylinder, consider:
Capacity Needs – Larger households may require a 250-300L system, while smaller homes can manage with a 135-180L cylinder.
Energy Source – Electric cylinders are more efficient, while gas continuous flow options provide unlimited hot water.
Heat Pump Water Heaters – These cut energy costs by up to 70% compared to standard electric cylinders.
At Laser Plumbing Wellington East, we help homeowners choose the best replacement system for their needs, ensuring energy efficiency and cost savings.
