1. You're talking local on-demand tankless. Most people in North America get whole-house tankless, as a replacement for a tank.Tankless is so your aged parent can wash her hands with warm water after peeing in the middle of the night without having to wait for the hot water to get there. She has a small unit under her bathroom sink.
Since a tankless unit isn't keeping a tank full of water hot 24/7 why doesn't it save energy?
2. Tankless will save energy, but it won't save money in most cases, because of the higher up front costs and because of the somewhat increased maintenance costs (unless you do all the maintenance yourself).
3. Part of the energy savings may also be lost by increased hot water usage. One study in the US suggested that homes that switched from tanks to tankless did on average use a bit more hot water.
