Water Heater Safety: Is Tankless Water Heater Safer?


Water Heater SafetyThe safety of water heaters have not been fully enhanced by many manufacturing companies. In turn, this has predisposed many users to dangers and health risks while handling the water in the bathrooms or at the water heater systems. This is through direct exposure of human body with electric power or extremely hot water which may damage skin or other body parts.

Many people have always complained about cases of injuries, burns, and even explosion while using their water heaters. Although many heaters are made in regard to the required safety measures, many incidences occur where users face safety issues while handling them. These include;

a) Explosion Hazards

Explosion of water heaters without a safety device, can cause damage to property, injuries, burns, and sometimes death. However, with a safety device such as; Temperature and Pressure Relief valve (TPR), a water heater can easily dump water in cases of high temperatures and pressures. Therefore, there should be a discharge pipe in buildings through which such waters can be wasted to prevent injuries and other risks.

Water heaters should be elevated above the floor, preferably 18 inches. This would reduce any chances of explosion or fire occurrences. Tank-type heaters should also be placed in positions adjacent to the wall. This will prevent any possible chances of breakages and tipping over in case of occurrences such as earthquake.

Automatic shutoffs together with TPR valve should be fitted in old buildings. Where temperatures rise to over 99 degrees C, shutoffs should be automatically conducted to prevent more heating and gas supply.

b) Thermal Burns

Water Heater SafetyHuman skin burns is a major problem and a risk posed by water heaters. Scalds are more susceptible to old people due to the disabilities and also slow reaction. Therefore, installing a tempering valve is essential on the water heater’s outlet. It mixes the hot water and cold water to reduce its risk in causing scalding.

Since sanitation requires hot water, a supplemental heater may be necessary in order to ensure that the water remains at a favorable temperature. Dishwashing machines are necessary for this purpose.

c) Bacterial Contamination

Warm water is a favorable breeding area for bacteria. This, in turn, calls for hot water able to kill the bacteria at about 55 degrees C. However, such water is responsible for causing scalding. Therefore, water should be kept at 60 degrees C so that though distribution and supplemental heating, a temperature of 55 degrees C can be secured by the time of use.

Water stored at 60 degrees C may encourage limescale deposit. Also, limescale deposits may be associated with bacteria in the water storage. One may use an outlet thermometer to detect the water temperature. However, storing hot water might be dangerous in causing the Legionnaire disease which thrives in the favorable temperature for domestic water use. Therefore, a household should consider using heating storages which heat water as it flows out.

Is Tankless Water Heater Safer?

According to the editors over at the www.tanklesswaterheaterguy.com in their tankless water heater reviews blog they claim that tankless water heater is among the most popular water heaters in the present times. Many refinements have been done to it in order to make it safer to being handled and used by human beings.

The heater is designed to heat water as it flows out for usage. The heated water is replaced by cold water. Thus, the heater prevents any cases of Legionnaire bacteria breeding. This makes the tankless water heater safer water storage.

At the same time, tankless water heater is set to heat water in favorable temperature for domestic use. This prevents occurrence of cases such as; scalding and explosions. However, you need to maintain your tank well in order to ensure it is correctly working.


Once you consider installing water storage, be sure to check the safety measures so as to secure yourself and your family. This will make it possible for you and your family to avoid risks associated with poor water safety. In addition to that, consider regular maintenance and repairing.
