Tankless water heater is one that provides hot water whenever you need, without actually storing the hot water. This is why it is also called a demand water heater or an emergency shower water heater. It heats the water directly as it comes through the pipe to the shower through an electric element or a gas-fire system. Although the initial cost of a Tankless Water heater may be high, it will definitely be worthwhile when you look into long term. The following points can help you understand how Tankless water heaters can be better than the conventional ones:
Energy Efficient: In case you use about 41 gallons of hot water or so, on a daily basis, a tankless water heater can help you save about 24 to 34% of energy when compared to a conventional one. If you want to save more, you can do so by installing a separate emergency shower water heater for each hot water outlet. By doing so you can save about 50% of your energy costs
One water heater for the entire house: While you may have to install one conventional water storage heater at each hot water outlet, one Tankless water heater would be sufficient to heat the water for the entire house. If you have more number of bathrooms in your house this will work as a convenient option.
Space Saving: By eliminating the need to install too many conventional storage water heaters, a tankless water heater will help you save on a lot of space. It will also make your bathrooms look airy and spacious.
No Heat Loss: In case of a storage water heater, it will heat the entire amount of water irrespective of how much water you are going to use. This will result in loss of energy or heat. A Tankless water heater on the other hand, can help you avoid such a loss completely. It will only heat the exact amount of water that you may need to use.
Constant Supply of Hot water: As against the conventional storage water heaters that heats up water in batches, tankless water heaters heat up water in a stable manner. Therefore once you install a tankless water heater you will be assured of a constant supply of hot water.
No Waiting Time: You get hot water almost instantly in case of a tankless water heater. However, in case of a conventional water heater you may have to wait until the water gets heated up which might take a long time especially during winters.
Long-lasting: While conventional water heaters have a life span of about 10 to 15 years, tankless water heaters have a life-expectancy of at least twenty years. The parts of these heaters can be easily replaced, which means you can extend their lives by even more number of years.
Once you have decided to go tankless your next step would be to decide upon the type of water heater to install. You can go in for an electric model or a gas-fired one. Nevertheless, it is better to know a few things before deciding on the type:
- An electric Tankless water heater will need proper voltage, a circuit breaker and amperage while a gas-fired model may need proper ventilation
- An electric tankless water heater is 99% efficient while a gas-fired one is 60% efficient
- You qualify for a rebate if you go for a gas-fired model depending upon the state you live in
It is definitely worthwhile to go for a tankless water heater. However, one has to ensure he goes in for a good plumber / electrician for proper installation and maintenance of the tankless water heater.
