The new and innovative tankless water heater systems can save you about $10 to $50 or so on average per month, on your heating bill. This is because they do not run very often at all, since they are instant hot water heaters. This means that no longer do you have to have a big bulky, in-efficient water heater tank that needs to keep a large amount of water hot 24/7. Obviously having to keep the water hot 24/7 is never going to be nearly as energy efficient as just heating up the water right on the spot. In fact, you can’t even compare the the normal water heaters to the tankless water heater systems.
The Rinnai tankless water heater system is one of the most popular ones on the market today. it works very well, and costs about $800 if you buy it from Amazon.com. We certainly recommend checking it out on Amazon, since it has tons of great reviews on there.
