While boiler-sized storage water heaters offered hot water in the past, shrinking spaces, rising-energy bills and a greater awareness in saving resources such as electricity and gas have turned people towards instant water heaters.

Unlike a storage water heater that heats up the water and stores it until someone opens a tap or turns on a shower, an instant water heater does not have any storage facility and simply heats up water instantly before it exits out of the water heater through an outlet. Such a water heater is also known as an on demand water heater. Such water heaters use an electric element to heat up the water or use natural gas or propane. A thermostat ensures that the water exits at the right temperature at all times. Instant hot water heaters that are used to heat a single bathroom or dishwasher or kitchen faucet are known as point of use water heaters, whereas larger models that can heat up multiple bathrooms or heat up all the taps and showers in a house are known as whole house water heaters.

Water heaters that utilize gas might not require electricity at all, and you can opt for a direct vent water heater that utilizes outside air for heating up your water while also expelling used gases outside the house for added safety. If you have an electrical outlet in the bathroom or under your kitchen sink and if you have very limited space then an electric tankless hot water heater that supplies hot water instantly when you flick on a switch would be a better option. Such a type of tankless water heater installation would not necessitate major plumbing or electrical changes although the electrical outlet should be ready to take on a higher load. When choosing an instant water heater it is important to check for the power consumption of that heater and the hot water flow of that heater before you make your purchase. Both of these factors will be mentioned on the instant water heater. The hot water flow will be mentioned as GPM or Gallons Per Minute.

There are several manufacturers that make instant water heaters and notable among them are Bosch, Rheem, Stiebel Eltron, Eemax, Paloma and Noritz, among others. Prices will depend on the type of instant water heater that you choose, i.e. the electric tankless model or the gas-fired model. You should pay heed to your requirements and match the model that fulfills your needs in a cost-effective manner. You should choose a model with a longer warranty period and make sure that the spares too are priced reasonably so as to end up with lower hot water heater repair bills in the far future. In most models, tankless water heater installation is very simple and a swift flick of the switch should reward you with a continuous supply of hot water.

You can step into any home improvement store or even browse over the Internet to choose the right type of instant water heater of your choice. You should compare features and prices before you choose the right water heater for your needs. You are sure to notice a substantial drop in your electric bills when you shift from a bulky storage water heater to a compact instant water heater even as you get rewarded with instantly hot water.

Most of us have grown up with a standard tank type water heater.  As such we are used to the way our hot water system works.  Switching to a tankless water heater will have an affect on the way your hot water system works.

With a tank type heater, when you turn on a hot water faucet, the hot water, typically 140 degrees, immediately begins flowing through the pipe to get to your faucet.  As the water travels through the cold pipe, it cools off until the piping material warms up.  That is why your hot water doesn’t instantly go from cold to hot; it has to warm up the pipes first. 

Many homes have hot water circulating systems that circulate the hot water through the pipes to obtain instant hot water at every sink.  Circulating systems can save a lot of water.  They are wasteful of energy though, since the water heater will fire up more often to replace the heat being lost through the piping which acts like a big radiator even if the pipes are well insulated. 

There are also pumping systems that pump the hot water to the fixture from the heater only when you want to use hot water and you don’t run any water down the drain. You still save the water and time, but you don’t waste water.

Tankless Systems

Tankless water heaters are being promoted as providing endless hot water and as being energy saving over traditional water heaters.  While both of these facts are true, there are other things to consider.

If you are considering replacing your tank type water heater with a tankless unit, and you have a typical house, make sure you get one large enough to do the job.  Since you are heating water as you use it, you must heat it much more quickly than a tank type heater so you need to add heat much more quickly. 

For a gas type heater this means you will be using a lot more gas volume/ minute than with a tank type heater.  Your exhaust flue will need to be much larger and the gas line might need to be larger. For electric units you might have to have special wiring put in to handle the high amperage loads created by a large electric tankless water heater.

With a tank type water heater you can set the flow rate to anything you want from full-on to just a trickle.  With a tankless water heater there is a minimum flow rate required to turn the heater on.  Typically it ranges from about ½ gallons per minute to ¾ gallons per minute.  So you can’t get just a trickle of hot water. 

Most circulating systems don’t pump at a high enough flow rate to turn on the tankless water heaters.  If they do, they will void or restrict most warranties, because they will cause frequent on-off cycles for the heater.

Changes in your water temperature from winter to summer will impact the tankless heater.  The tank type heater always heats your water to the same temperature.  The tankless units increase the temperature a certain number of degrees with a given flow rate. 

For example, if your incoming water temperature in the summer is 60 degrees, and your heater raises the temperature 80 degrees at a flow of 1 gallon per minute, you have a hot water temperature of 140 degrees.  If your incoming water drops to 50 degrees in the winter, your top temperature will drop to 130 degrees.  And don’t forget, as you increase the flow rate the temperature rise will drop.

To fully heat the hot water, the cold water entering the water heater must pass all the way through the water heater.  This means that it will take longer to get your hot water than with a tank type heater, and you will run more water down the drain.

The water conservation issue can be resolved with a “demand” type hot water system. Demand hot water pumps pump the hot water from the heater to the fixture without running water down the drain. The pump only runs for a short time, usually less than a minute, and thus only consumes about .00 per year in electricity costs for a typical family. A demand pump will get your hot water to your fixture about twice as fast as normal and you won’t waste any water. Demand pumps can be found for less than 0.00 and are very easy to install.

Tankless water heaters can save you a modest amount of energy, typically around .00 - .00 a month. Since tankless units are more expensive than tank type water heaters, and more expensive to install, that savings may not be so great. They can also provide you with endless supply of hot water. However, forget getting a trickle of hot water, be prepared to wait a little longer, and adjust to having the temperature vary with the flow rate.
