If you think tankless water heaters are not ideal to cover the hot water requirement of an entire household, you should think again. There are now available whole-house tankless water heaters that are specifically designed and made for households.
It is not surprising how many consumers prefer to invest in such fixtures. Many retailers are now carrying and selling such appliances because demand is constantly increasing.
Households that are aiming to significantly cut on costs would find whole house tankless water heaters ideal. These heaters could significantly lower overall water-heating bill by about 5% to 50%.
The savings could be possibly greater. This fixture is designed to heat water that is moving through the system. In comparison, the conventional water heater system is heating an entire tank of water and keeping it hot.
Supply of hot water heated through the whole house tankless water heater could be endless. There is no possibility that you would empty thewater heater tank because of a tall bath.
This is because there is actually no water tank to empty. The issue intankless water heaters is not capacity but flow. The water heatersystem would not run out of needed hot water unless flow surpasses the tankless water heater’s ability to heat.
Thus, the heating capacity of the tankless water heater for the whole house could be altered if use is simultaneous. For instance, if you use two showers and a washing machine exactly at the same time, the heater might not be able to provide water that is hot enough.
The water provided could be lukewarm instead of hot. To remedy the situation, you would need to stagger the use of showers and the washing machine just for several minutes and the operation of the whole house tankless water heater would be normal.
Thus, with the tankless water heater for the whole house, you could easily fill even an oversized bathtub. However, you could not easily do so if you are using another fixture or appliance that uses hot water at the same time.
Whole house tankless water heaters are usually using burners that are fully gas powered (by either kerosene of propane). Thus, venting may also be required. The flues could possibly be bigger than those that conventional gas water heaters require. Some models feature pilot lights, while others have electronic ignitions that are requiring electrical hookups.
