Preparing for the death of my home water heater. Since the space in my house is small like on many boats, I thought that a tankless system might be worthwhile. Anyone have one or know if the initial cost is worth the investment?

Looked in to it last year Cost No Problem, availability No Problem ,Space saved HUGE Problem!! just One, Cost of additionial Generator.!
Unfortunitily the amount of Amps drawn would give you a brown out. Not to mention wiring up grades needed.
I appreciate the insight. Also wondering how long it takes for hot water to reach the end use and how much water can be created?
Rennai makes several gas fired units. They are terrific. Temperature can be set. When there is no need for hot water, they are off. They do require a small amount of electricity to run a purge fan for the exhuast. These are designed for home use. The drawback is that you do have to run it for a minute for the water to heat up, in other words, you must run wate through it for a minute. Turn the water off, the unit goes off. Pressure demand switch. So yes, you do waste some water, until you get the hang of it, you can use the initial water to do things like brush your teeth with cold water... etc.
We have had one for about 3 years now, and love it.
Great information, thank you. Currently we have no gas appliances, is there a benefit to choosing gas appliance over electric?
Typical domestic uses of hot water are for cooking, cleaning, bathing, and space heating. In industry, both hot water and water heated to steam have many uses.

Sorry to disagree with jlyacht, but we installed two of them (side-by-side) in the lazarette on our West Bay Sonship to replace the single tank-type residential-type electric heater. We have had zero problems with electrical overload or wiring harness issues. We saved a significant amount of space, they are easy to access, are simple to install and we never even had to change as much as a circuit breaker. Additionally, they have far less sheet metal...actually none...which is one less item to rust in the salt air. They are encased in a heavy pvc or plastic of some sort. One of the best conversion we did. Best part is that the hw is instantaneous and the recovery time is non-existent....as fast as you can use the water, these babies keep up and keep right on giving all the HOT water you'll ever need.
