Gas and Oil Home Heating Furnaces - tankless water heaters

Has anyone had any experience with tankless gas or electric water heaters for home or pool use? I've been looking at these as an alternative to a pump system to provide instant hot water at sinks and showers. Please let me know any experieces you might have with either. Thanks

If your basment is not finished, or you have access to the hot water pipe. Insulate the hot water pipe right to your tap if you can. This will make a difference. Also buy a solar blanket for your hotwater tank, if the tank is warm your loosing heat.Wrap it with a solar blanket,but remember not to wrap the releif valve.Cut a hole in the blanket and pull the blanket around it.Most hardware stores carry this.

Believe they are the same.An on demand (propane or nat gas) hot water heater heats water only when you need it.There is no need for a 50 or 75 gal water tank that you need to keep at a specific temp...When hot water faucet is opened the pressure drop starts gas burners.When water is shut off burners do also.The system will have to be vented properly.Some smaller resturants in Maine use these to supply hot water to dishwashers.They supply sufficient hot water to keep temp up, to health inspectors specs.PDF

Have had little experience with them but I know they won't produce enough hot water if there is a large demand at one time and can be pretty expensive to purchase.

Here is another link, and they claim their heater will run 2 showers and a 3 hotwater consumuer - at the same time. 6.4 GPM of hot water supply.
