I really want a tankless water heater

My house has only one major closet.

What really stinks is that the indoor air handler takes up half of it and the water heater takes up the other half.

I have been plotting on how to free up space. I want to be able to store coats, shoes and cleaning supplies there. The indoor air handler can go when the HVAC dies. I plan to have a ductless HVAC unit in my house. The indoor air handler will then be a wall mounted unit in every room of the house. I then can free up one half of the closet. When the water heater goes I am going to choose a tankless water heater. A tankless water heater is about the size of a small suitcase and fits onto the wall. I would free up near the ceiling and the floor space. A tankless water heater works better too. You get hot water on demand. Right now when I want to shower I need to start the water and wait for it to heat up. With a tankless model. I get it right away. There is no running out of hot water either. In the winter when I want to warm up, I always have to rush so my husband gets a hot shower. A tankless model also frees up that issue. It will be expensive and require a licensed plumber to do the water heater installation. I am more than ready though. I am sick and tired of dealing with a giant water heater and all sorts of problems. It is only ten years old though. I think I am going to be stuck with it for a while.
