Understanding your system

Crafted from high-grade marine stainless steel, this cylinder offers inherently clean, durable hot water storage without needing a sacrificial anode.

Anode-free design

Stainless steel doesn't require a sacrificial anode rod, which means lower long-term maintenance needs and zero risk of the chemical "rotten egg" odors that can sometimes affect enamel tanks in specific water profiles.

Lightweight and efficient

Highly efficient heat retention properties keep standby energy losses to an absolute minimum.

Routine servicing and system care

To prolong thelifespan of your cylinder and keep it running smoothly, follow this simplemaintenance schedule.

Every 6 months - Homeowner Check

Ease the TPR valve

Gently lift the lever on your Temperature & Pressure Relief (TPR) valve for a few seconds to flush out any trapped grit. Verify the line completely stops dripping once closed.

Check the Safe Tray

Ensure any internal safety trays under the unit remain dry and unobstructed.

After 12 months - Professional Service

After the first 12 months, this initial service is vital as it determines the level of ongoing maintenance needed specific to your location and environment. To keep your system running optimally for its full lifespan, book this annual check-up with Hot Water Shop. Our technician will check element integrity, test electrical connections, clean inline filters, and ensure all pressure reduction valves are working flawlessly.

Quick Fixes

Before calling for service, double-check these simple fixes:

No hot water at all

Check your home's main switchboard panel to ensure the hot water switch hasn't tripped off.

Reduced pressure

If your hot water pressure suddenly drops while cold water stays normal, your inline cold water expansion or pressure reduction valve might be clogged with water-main debris.

Tim’s Efficiency Tips

The 60°C sweet spot

By law in NZ, stored hot water must be kept at a minimum of 60°C to prevent legionella bacteria. Your cylinder's internal thermostat is calibrated to balance maximum health safety with efficient power usage.
