If you are looking for a great way to lower your monthly expenses you will probably want to buy a Rinnai tankless water heater at some point. The Rinnai tankless water heater is hands down the best way to save on your hot water / electric bill, since it does a much better job at heating water than a traditional water heater tank. The Rinnai tankless water heaters are far more efficient because they do not store hot water; they actually heat it up instantly, right on the spot, which means that they only use propane gas when you turn on your faucet.

A regular water heater must keep a large amount of water hot at all times, so the heating element will cycle on and off all the time throughout the day. This is very expensive, since it uses a lot of electricity every time it has to run the heating element. This problem is eliminated with the Rinnai tankless water heater, and that is why it is called an “instant hot water heater”.
