Thinking About Installing a Tankless Water Heater in Langley

I'm considering upgrading to a tankless water heater for my home in Langley and would love to hear about others' experiences. Are they more energy-efficient than traditional water heaters? I'm looking for a reliable company that offers professional installation, fair pricing, and quality workmanship. If you've recently had a tankless water heater installed in Langley, I'd appreciate your recommendations and any tips before making a decision. Thanks!
