yes
It will increase the current since the water heater is made of a heating element and which is resistive in nature. Ohms law states that V=IR where V is the voltage, I the current and R the resistance. Now the resistance will always remain constant. Thus, when the voltage is increased, the current will also increase.
There is a thermostat inside an accessible panel on the hot water heater. The panel is typically secured by two screws. When the temperature goes below the set level the heater turns on. You'll either see a specific temperature or just an adjustment that says hotter. Some installations have an external timer that might turn off the hot water heater between midnight and 5AM, for example.
The typical flue gas temp at the inlet to the air heater is about 650-750 DegF range.
Because the heat from a heater is already in the lowest from of energy possible, physical heat at only a few degrees above the ambient temperature.
The wattage of electric base board heaters does not change because the thermostat is set on low. The wattage is a fixed value on the heater because of its internal resistance element. The thermostat set on low shuts off at a lower temperature than a thermostat that is set on high. It is the time interval that governs the amount of heat that the heater produces when the thermostat calls for heat. Once the room heats up to the temperature that the thermostat is set at, the heater shuts off. The thermostat is just a temperature switch.
Have you turned the control from Pilot to On? Have you increased the temperature setting?
If you bypass the heater core the air temperature coming into the vehicle will not be increased ( so no )
Pool temperatures can be increased by installing a pool heater. They can also be raised by using a solar blanket.
Hot
No, the pump will continue to pump water and the heater will work from the thermostat setting keeping a constant temperature.
This depends upon how high the temperature is increased. To make food cook quicker, when water is placed in a pressure cooker it is allowed to heat up to a much higher temperature than its normal boiling point of 212 degrees Fahrenheit at sea-level. But, at a certain preset pressure, the pressure relief valve will open and release steam. Without this valve the cooker would explode. The same is true for a water heater in your home.
It's all to do with the latent heat of fusion (melting(Ice to water), and the latent heat of vaporisation (boiling( Water to steam) Stands for any substance. It is because all heat created by the heater, will be used as energy to break the lattice holding the atoms in their state. Once the state is fully changed, the heat energy will then be used up by raising the temperature. More can be found here: http://en.wikipedia.org/wiki/Latent_heat
Install a bigger water heater. This would only be efficient if you had a constant need for an increased volume and could bear the added cost of installing, operating and maintaining a larger heater. Or increase the temperature on the water heater so you use less to get warm water. This also has its practical limits, where water could be delivered to the faucet at a dangerous temperature (over 130 F), unless properly controlled. Or install another water heater in parallel, giving you twice as much hot water before it starts getting cool. Larger facilities may have three or more heaters in parallel and another one in series for pre-heating the supply to the others.
The heater fan ONLY blows the air, it does not make the temperature of that air. Your heater temperature controls how hot the air is. Adjust your heater temperature for hotter or cooler air.
The correct temperature for tropical fish is 72 to 80 degrees. I keep mine at a constant 75 degrees with a heater designed for aquariums.
The heater hoses on a 305 engine run from the intake manifold to the heater core and the heater core to the radiator. This creates a constant source of heat to supply the heater.
You will need to know the current water temperature in your tank by using a thermometer, so you know if you need to increase or decrease the water temperature for your fish. Take your heater, place it in the tank according to the instructions, DO NOT plug the heater in for at least 20 minutes. After plugging the heater in, slowly turn the thermostat up until the heater light comes on and turn it back until the light goes out, if the light is on when you plug the heater in, slowly turn the thermostat down until you find the point where the light goes out. You have now just adjusted your heater thermostat to the current water temperature, turn it up or down as needed, but only by a small bit and allow 24 hours for the water to heat up or cool down, before adjusting the heater again.
