Reliance Water Heater Replacement Elements
Replacement heating elements for Reliance electric water heaters — screw-in and flange styles, matched to your tank's wattage and voltage.
Reliance is one of the most common electric water heater brands installed across Canada. Unlike our coil-wound kiln and HVAC elements, water heater elements are sealed, waterproof units built by a specialty manufacturing partner — we match a replacement to your Reliance tank's wattage, voltage, and thread or flange pattern, and ship across Canada.
- Compatible replacements for Reliance equipment.
- Send your model number for an exact match.
- Correct fit, spec, and connections — no guesswork.
- Canada-wide shipping through a trusted manufacturing partner.

Frequently asked questions
Will your elements fit my Reliance water heater?
We match replacement elements to Reliance units by wattage, voltage, and dimensions — not just the brand name. Send your model number or a photo of the old element's data tag and we'll confirm the exact fit before you order.
How do I find my Reliance model number?
Check the rating plate on the unit — usually inside the access panel or on the cabinet. It lists the model and serial number, which is all we need to match the right element.
Do you carry elements for older or discontinued Reliance models?
Often, yes — many Reliance tank models share the same industry-standard element sizes, so a compatible replacement is usually available even for older tanks. Send us the details or a photo and we'll confirm.
Can I use an element from one Reliance model on a different Reliance model?
Usually not directly — even within the same Reliance lineup, models can differ in chamber or cabinet size, wattage, or voltage, so elements aren't universally interchangeable across models. Send us both model numbers (or a photo of the data tag) and we'll confirm whether the same element fits, or spec the right one for your exact model.
