What if I forget the water heater on?
Most of us have at least once in our lives forgotten the water heater – θερμοσίφωνα τοποθέτηση – on for one (or more) days. Either due to carelessness, or because the water heater may not have an “on / off” indicator lamp or it has but it is damaged or in an invisible place.
Many questions can bother and stress you when you leave the water heater on. You will surely wonder what will be the next electricity bill that you will face or if again your water heater could explode from the long operation.
We are here to give you an answer to the basic question that concerns you: What happens if I forget the water heater on?
What if the water heater is on?
First you need to know that if you forget your water heater is open, the end of the world has not come. Most likely there will be no problem. But remember not to make it a habit. The waste of energy is great, while you increase the chances due to its continuous use, to suffer some damage and then the intervention of a plumber or an electrician will be necessary. Therefore it would be good to be careful.
How does an electric water heater work?
The electric water heater has a built-in thermostat which is set to a specific temperature. If the water heats up, it will command the electrical resistance to turn off and turn it on again as soon as the water temperature drops, even if we have not consumed any water.
Therefore, if you leave your water heater on permanently, you will definitely cause energy waste. The higher you set the thermostat temperature, the greater the energy loss you will have if you forget to turn it on.
So to reduce energy losses, you could schedule the time of day you want the water to be heated by installing an automation system.
Water heater change resistance
If you have again noticed that while you forget your water heater is open quite often, the water is still cold and not at the desired temperature, then there are two possible scenarios:
1. The thermostat has defrosted and dropped to low temperatures, which requires you to adjust to the ideal temperature according to the instructions for use.
2. There is a problem with the resistors, the solution is in their immediate replacement.
It is not recommended to solve such a problem on your own, because the possibility of causing a more serious damage is high. So you need to call a specialist immediately to help you effectively with your problem.
Inflated electricity bills myth or truth?
Most people think that if they forget to turn on the water heater, they will be faced with an unpleasant surprise at the next electricity bill. But what is really the truth? If you have forgotten the water heater is open for a whole day but without wasting a lot of hot water, then the charge you will have will be almost negligible.
The electric water heater in the beginning, heats the water and consumes a lot of electricity. When it reaches the right temperature, the thermostat will stop heating it and will simply maintain it with much lower power consumption.
Is there a risk of explosion due to continuous operation of the water heater?
Many times we have heard the phrase “turn off the water heater because there is a risk of explosion”. It is true that in older types of water heaters such a danger really existed.
However, with the development of technology and the creation of new water heaters, there is no longer such a fear, especially if you have installed it in recent years. In any case, of course, it would be good to ask the opinion of an expert.
Is the water heater safety valve dripping? Is the water heater safety valve dripping? Do not worry! It is the most common cause of leakage in a water heater. Below you will learn how to repair a water heater, if there is a problem with a leak in its safety valve.
What is a safety valve?
Initially, the safety valve is placed at the cold water inlet of the water heater and does not allow the reverse flow of water from the water heater to the water supply network.
What is the utility of the safety valve?
The installation of the safety valve in the water heater serves two purposes:
In the event of a sudden rise in water pressure and temperature inside the water heater, the safety valve releases water to balance the pressure and return it to normal levels.
As mentioned above, the safety valve prevents the return of water to the network. In the event of a water outage, the valve prevents water loss from inside the water heater.
The safety valve is activated by a certain pressure limit and above. This limit now ranges at 6 or 8 bar.
Why is the safety valve of the water heater dripping?
When the temperature of the water increases, its volume expands and increases. Therefore, the pressure inside the water heater increases and as soon as it reaches the limit, the safety valve is activated and releases water.
In older safety valves the pressure limits ranged from 10 bar. But in recent years these limits have been reduced. As a result, the valve is activated more frequently to reduce the pressure inside the water heater.
Also, EYDAP has proceeded in recent years to install corresponding non-return systems in the water network, so that water does not return to the main pipe in case of increased pressure.
As a result, as the pressure of the water heater in a house increases, the water cannot be discharged back to the mains.
Water heater safety valve dripping – What are the solutions?
There are two basic steps you can take to begin the process of preparation for mediation.
First, you need to know the pressure on your local network. Indicatively, the most common pressure value in a city network is 3-4 bar. So:
- If the city mains pressure is less than 4 bar, then you need to place an expansion tank between the water heater and the safety valve.
- If the pressure of the city network is greater than 4 bar, then you need to install an expansion tank, as well as a pressure reducer in the central cold water supply.
We hope we have helped you with any questions you may have if you leave your water heater on.
