If your water heater originally runs on DC 3V batteries, this converter is likely compatible. We recommend checking your water heater's battery compartment voltage requirement before purchasing to confirm compatibility.\u003c\/p\u003e\n\u003ch4\u003eQ: How difficult is it to install the power supply transformer?\u003c\/h4\u003e\n\u003cp\u003eA: Installation is straightforward — the unit is designed to replace the existing battery box on your flue-type water heater. Simply connect the output leads to the contacts where your battery holder was connected, and plug the transformer into a standard AC 220V wall outlet. Always ensure the mains power is switched off before making any electrical connections, and consult a qualified electrician if you are unsure.\u003c\/p\u003e\n\u003ch4\u003eQ: How long is the power cable, and is it long enough to reach a wall socket?\u003c\/h4\u003e\n\u003cp\u003eA: The transformer comes with a 1.8-metre (approximately 6-foot) cable, which is sufficient for most standard installations where the water heater is located near a wall outlet. If your outlet is further away, a suitable extension lead may be used.\u003c\/p\u003e\n\u003c!-- production-packaging-notice --\u003e\n\u003ch3\u003eProduction \u0026amp; Packaging Notice\u003c\/h3\u003e\n\u003cp\u003eTo maintain high stock availability and fast shipping times, our items are sourced from multiple verified manufacturing facilities.
