If you currently have a tank type water heater, I would replace it with the same type. A tankless unit will cost more money to buy and to install. You may need to modify your gas service and possibly your electrical service. Also, if the tankless water heater breaks down, how long will you be without hot water if the technician needs to order a part? A tank type water heater can usually be replaced within a day or less by almost any plumber. I don't think the advantages will be worth the cost, if there are any measurable advantages.
