Not much, it gets warm as everything else within the heater's range.
The warmed water next to the heater becomes hotter when the heater is switched on.
yes
It may be next to it but never above it.
it will heat up..
One hazard is being next to water when you play.
replace your heater hoses going into and out of the heater core. One of them is probably split.
The electrical unit on the water heater may be shorting or you may need to install a filter before the water heater as particles may be breaking the element inside.
Any reaction occur.
It is probably right next to the water heater. There should be a shutoff at the floor, if not then at the meter is the most likely shutoff.
the heater box is under the dashboard most of the time in the middle. The heater blowing system have doors . The door for the foot is next to your leg he have one metal cable could be this come out. If yes, have to clip it back. This electric its more difficult but just check first
The life expectancy of a tank-type hot water heater is 13 years. For most of this time, the water heater will perform without any attention, then all of a sudden, you find water all over the floor. Before you rush out and make an emergency call to your plumber, there are several things to consider. The first is what size hot water heater your family needs now and for the next few years. Perhaps the size of your family has changed. If the kids are growing up, you may want to consider getting a larger heater. Teenagers tend to take longer showers and consequently use up more hot water. On the other hand, maybe the kids have moved out of the house and you can get by with a smaller size. What is the availability of different fuel types? If you have both natural gas and electric available, you can change if it makes economic sense. Electric water heaters cost less initially and are simpler to install. However, electric utility rates tend to be higher so the operating costs over the years will be higher when compared to natural gas. Gas water heaters are a little more complicated. They need adequate venting for the flue gases and a sufficient air supply for combustion. This makes the location of the heater more critical. Gas backdrafting is also a consideration and carbon monoxide detectors may need to be installed. The efficiency of the water heaters is a major factor. Electric water heaters have energy factors above 95%, while natural gas heaters are in the range of 60% to 65%. Tankless water heaters have become more popular in recent years. Their efficiency is higher, around 80%, because they do not have standby heat losses from a tank. Based on average gas rates, a tankless water heater will save about $100 per year for the average homeowner. The initial cost of a tankless heater is higher compared to gas and electric. Determine the payback period to see if the annual fuel savings justify the additional cost of the unit.
