FAQs

What hot water system parts do electricians most frequently replace?

Heating elements and thermostats are the most commonly replaced components in electric hot water systems. Elements typically fail due to mineral buildup or age, while thermostats malfunction when temperature control circuits deteriorate, both requiring licensed electrician replacement to maintain system safety and efficiency.​

Which element wattage should I select for residential hot water repairs?

Residential electric hot water systems typically use 2400W, 3600W, or 4800W elements depending on tank capacity and household demand. Contractors should match the original element wattage specification to maintain proper heating performance and electrical circuit compatibility.​

What’s the difference between Incoloy and copper heating elements?

Incoloy 800 elements offer superior corrosion resistance and longer service life in hard water conditions compared to standard copper elements. While copper elements provide cost-effective solutions for standard installations, Incoloy elements are preferred for commercial applications and areas with aggressive water chemistry.​

Do you stock thermostats with adjustable temperature ranges?

Our thermostat range includes adjustable models spanning 50-70°C, 60-80°C, 60-90°C, and 65-95°C temperature ranges with built-in over-temperature cut-out protection. These professional-grade controls suit various residential and commercial hot water system requirements while meeting Australian safety standards.​
