Tankless Heaters

One thing I like about our new place is that the hot water was installed before we moved in. This avoided the problem of having to install outside hot water heater units which can look a little cumbersome. However, I recently read about a new product called tankless water heater which you can install easily into your bathroom without ugly tanks sticking out of your wall. Maybe I should find out more about it and install it into my new place when I take it back from the tenant.
