The Water heater is among those neglected appliances in homes, typically tucked away in some corner of their garage. We do not pay much attention to it till it breaks. It has existed in its current form for quite a long moment. It had been invented in 1889 by Edwin Ruud and it hasn’t changed much since then. It is made up of a 40 or toaster cylindrical container using a gas burner or sometimes an electrical component. It heats the water slowly and keeps it hot all the time.
Its burner has a pilot light that is burning gas constantly and the primary burner comes periodically into actions to heat the water because the water in the container has cooled off. Well, that goes on day in day out even if the water is not used. That is because the water loses its heat to the surrounding. It is like having a kettle full of water on the cooktop all the time. The newer tank water heaters tend to be much better insulated than before to reduce the standby heat loss but not the less they lose heat and the water has to be continuously repeated. In today’s times where energy is now expensive and will become even more that’s an entire waste of energy and money. It burdens the environment unnecessarily and leads to earth warming and climate change.
The tank water heater is also quite inefficient, not only loses its heat, standby heat loss, but it also does not do a good job heating the water through its inherent design. When new they have an efficiency of about 55%. Depending upon the hardness of the water it may rapidly fall to 30 or so percent because of water sediments buildup at the base of the tank, exactly like the pot where water sediments build up when water in it is heated over and over. The tank WH has health problems as well. Bacteria and germs adore the standing warm water and grow easily and rapidly in that environment.
The water is usually not hot enough to kill them. Over time there may also be rust build up in the water tank that reduces the heating efficiency of the WH in addition to it being delivered to the bathroom faucets and the kitchen sink. Sometimes you can see the rust in the tile grout discoloration. Not all that is unhealthy but a lot of times simply undesirable. The tank WH does push out a number of those sediments and some of it remains in the tank and keeps setup. It isn’t only in the bathrooms we use hot water but most of it is being used for bathing. We use hot water also to wash dishes occasionally and prepare meals. Now if you could see those microscopic foreign elements, bacteria, and sediments you’d think again of utilizing it for food or even bathing the kids in the tub with water.
It has happened to all of us we ran from hot water carrying a shower or a tub. And there isn’t any rapid heating of the water. The WH is simply not designed for this and it requires a lot of energy and time again to warm 40 or more gallons of water. A lot of families have to schedule their showers since in a family with numerous persons you immediately run out of warm water. To create that warm water last a bit longer you can run the WH in a higher temperature; state 180 degrees Fahrenheit so you combine more cold water with the warm water. Running the WH at greater temperature wastes much more energy and with it of course cash.
Typically people take showers in the morning before leaving home. The WH isn’t intelligent to understand that after the shower you all leave the house and will not be needing warm water before later in the day when everybody gets home again. So it heats up the water and keeps it hot all day by heating and heating it over and over. And of course it doesn’t understand you won’t be needing warm water following a shower and going to sleep, so it warms the water up and keeps it hot throughout the night.
Storage tank water heater leaks can be costly.
Well, another issue with tank WHs is they tend to flow water with time. Occasionally this occurs for a very long time without being noticed. Since most water heaters are placed in the garage they are usually out of sight and nobody pays attention to them. So water damage due to a water leak may go on for a lengthy time unnoticed and cause considerable damage to the house and encompassing along with wasting water and energy. Water damage to subfloors or alternative structures of homes is not uncommon and the fix of it will be costly because it wasn’t detected early.

In earthquake-prone areas, water heaters pose a different problem too. If not properly anchored they can tip over and cause water damage, physical damage and of course fire. Water heaters have dropped on cars parked near to them in the garage and considering the burden of a 40 approximately gallon WH filled with water is approx. 330 pounds plus approx. 120 pounds for the heater itself, therefore a total of 450 pounds decreasing let’s state on a car’s hood. Now that will do considerable damage not just into the hood of the car but also to what is under it.
And in this case, it is also going to disconnect the gas line and we’ll have a gas flow as well that can result in fire and further harm. So it’s extremely important to make sure the tank WH is properly anchored to something which can hold the weight in case. Steel and aluminum straps should be strong enough and anchored to main wood studs or masonry walls.
The pressure relief valve on Tank Water Heaters
One other thing to pay attention to is your pressure relief valve. As its title implies it releases the water pressure to the exterior by discharging excess water from the tank to avoid an explosion of the tank WH. You may be surprised to know how frequently that occurs that a small pressure valve fails and the water heater actually explodes. The excess water from the pressure valve, of course, should be hauled to the exterior or a drain that won’t lead to water damage. enersure.ca/
