Typically, a hot water heater that uses a tank will run for three to five hours per day. So, a 4,000-watt heater used for three hours a day at $. 10 per kWh will cost $1.20 per day, about $36.50 per month, or $438 per year.
Water Heater
Water heaters, even those that burn a fuel like natural gas, need electricity to run. All water heaters use electricity for some of their functions. Natural gas based water heaters generate their own electricity, but electricity-based water heaters must have the power supplied. No power means no hot water.
Electric water heaters are essentially the same as gas water heaters, with the only difference being that they use electricity as their fuel source to heat the water through upper and lower heating elements. Gas water heaters only use a lower heating element.
In most cases, even if the power has gone out, you will still have some hot water that is being stored in the tank and will be there until you run through it. Whenever it runs cold, you will have to wait for the power to come back on to reheat the system.
Using your plumbing during a power outage is completely safe. Obviously, if you are worried about electrical surges or other rare occurrences then you shouldn't take the risk for a hot shower. Your safety comes first during a power outage which is why it is important to have flashlights ready for just such an occasion.
Can I Shower if the Power Is Out? In order to shower during a power outage, your home has to be equipped with a traditional tank-style water heater. Additionally, it needs to have hot water already in reserve, which it should but might not. And finally, if you plan to take a shower, you need to do it soon!
The pump won't work when the power goes out. There may still be room in the septic tank for a few flushes, but you risk overfilling it and a nasty sewage backup if you flush too often.
Keep refrigerator and freezer doors closed. If the doors stay closed, food will stay safe for up to: 4 hours in a refrigerator. 48 hours in a full freezer; 24 hours in a half-full freezer.
Unplug Electronics
Sensitive items like computers, televisions, and microwaves should be unplugged after a power outage occurs. Sudden power surges can destroy these items, and it's always better to be safe than sorry when it comes to your appliances!

Gas water heaters cost less to operate than electric water heaters—about 33% less.
Hot water systems are more expensive upfront. However, given the many benefits they provide, we here at American Vintage Home encourage customers to consider everything they stand to gain from hot water heating. Cannot add an air conditioner to a boiler.
Showers make up a huge share of water and energy consumption. In fact, showering for one minute consumes more energy than using the lights in a 3-person household for an entire day. For example, an average European household requires 2,6 kWh to heat up the water to a pleasant temperature.
The cold water pipe brings water to be heated into the bottom of the tank where the heating elements are located. As the water warms, it rises to the top of the tank to be removed on demand by the hot water pipe. If hot water is not being used, it sits in the tank, being continually heated.
The main reason that a natural gas furnace won't provide heat if it doesn't have electricity is because the blower motor that powers the blower fan requires electrical power. The furnace can produce heat inside the combustion chamber—but that heat won't go anywhere if the blower fan isn't running.
All things plugged in will bleed some energy. Called "standby" electricity loss because it's so often associated with electronics in standby or idle mode, it's also known as "phantom" or "vampire" electricity (for obvious reasons). Even turned off, many appliances keep drawing power.
You should disconnect your desktop computer, monitor, laptop, printer, scanner, modem, or anything connected to these elements after use. Turn them off every night and when they are not in active use.
In advance of the storm, prepare your home by unplugging unnecessary appliances as they could be damaged when power is restored. Using high-quality surge protectors can help with protecting appliances.
As the USDA notes in Keeping Food Safe During an Emergency, your refrigerator will keep food safe for up to 4 hours during a power outage. Keep the door closed as much as possible. Discard refrigerated perishable food such as meat, poultry, fish, eggs, and leftovers after 4 hours without power.
The following items are safe (if they had been opened/refrigerated): Peanut butter, jelly, mustard, ketchup, olives, pickles, Worcestershire sauce, barbecue sauce, hoisin sauce, fish sauce, soy sauce, vinegar-based dressings, fruit, raw vegetables and hard cheeses (including grated).
Refrigerated foods that can be held at temperatures above 40ºF until power returns include: hard cheeses, butter, margarine, fresh fruits, fruit juice, fresh unpeeled vegetables, salad dressing, ketchup, mustard, olives, pickles, jams, jellies and peanut butter.
While older stoves may be usable during a power outage, most new models will not be. Before trying to cook with your gas stove, check your range's manual to see whether it includes an interlock. The interlock is a feature that prevents any gas from entering the appliance unless there is electricity.
Fill the bathtub with water to be used for toilet flushing during a loss of power. If your well is flooded or damaged by the hurricane, assume that it is contaminated and do not use it until it has been flushed, disinfected and tested for bacteria. Turn off utilities if instructed to do so.
Swimming pools, hot tubs, and nearby bodies of water can also be good sources of water for flushing toilets. Because of the chemicals in pool water and the unknown substances in natural bodies of water, please don't use it for any other household or drinking purposes.
