Frequently Asked Questions
Q: Which water heaters is this AC to DC transformer compatible with?
A: This transformer is designed for flue-type gas water heaters that use a DC 3V battery power supply for ignition. It replaces the standard battery box, converting AC 220V mains power into a stable DC 3.0–3.5V output. Always verify your water heater's required input voltage before installation.
Q: How long is the cable and is it long enough for most installations?
A: The transformer comes with a generous 1.8-metre (approximately 6-foot) cable, which provides ample reach for most standard water heater installations where a nearby 220V wall outlet is available.
Q: Is installation difficult?
A: Installation is straightforward. The transformer connects to the same terminals as the original battery box on your water heater. Simply disconnect the old battery compartment, connect this adapter in its place, and plug the other end into a standard 220V outlet. If you are unsure, consult a qualified electrician.
Q: Will this work in countries with 110V mains power?
A: No. This transformer is specifically rated for AC 220V input. It is not suitable for 110V mains supplies without a separate step-up converter. Please ensure your local mains voltage is 220V before use.
