Why does my furnace keep blowing hot air?

Why does my furnace keep blowing hot air? Furnace overheating can be the cause of your cold air dilemma. Changing the dirty air filter can solve this problem. The dirty air filter blocks the airflow, causing the furnace to run longer to heat your home until it overheats. It is important to note that constant overheating can damage your heat exchanger. Why is my furnace running in the summer? A: Nothing is wrong with the furnace. The house stays comfortable in summer because the furnace is not producing heat. During the heating season, when the outdoor air would cool down...

Why are boilers so dangerous?

Why are boilers so dangerous? A faulty boiler, or one that has a blocked or leaky flue, can release a poisonous gas called carbon monoxide (CO). As well as the dangers of carbon monoxide (CO), a gas leak from your central heating can cause a fire or explosion. This can result in catastrophic consequences. What are old boilers made of? Materials. The pressure vessel of a boiler is usually made of steel (or alloy steel), or historically of wrought iron. Is a boiler the same as a furnace? The easiest way to remember the difference is to understand that a...

Why does my gas fireplace have an odor?

Why does my gas fireplace have an odor? When burned, methyl mercaptan has an odor similar to burnt matches and rotten eggs. When vent-less logs burn in a fireplace, natural gas additives burn along with the gas. As a result of this combination, fireplaces will emit a kerosene odor when burning within a vent-less environment. Should a vented gas fireplace smell? You should not have any odor or soot enter into in your room if the fireplace chimney is venting properly. The reasons for soot going into the room may include: - Damper not open or not open far enough....

How much heat does it take for water to evaporate?

How much heat does it take for water to evaporate? Heat (energy) is necessary for evaporation to occur. Energy is used to break the bonds that hold water molecules together, which is why water easily evaporates at the boiling point (212° F, 100° C) but evaporates much more slowly at the freezing point. How many BTU does it take to change water to vapor? LATENT HEAT OF VAPORIZATION For water in an open pan, it is 970 Btu per pound, so 20 pounds of water at 212° requires 20 × 970 or 19,400 Btu to turn it into steam or...

What is on coil and off coil?

What is on coil and off coil? On coil is the temperature of air just before passing through the coil. Off coil is the temperature of air just after passing through the coil. Supply Air Temperature is the condition of air just at outlet of terminal unit / any air outlet device in the system. What is normal coil temperature? The evaporator coil is cold (about 40° F), and the air from the house is warm (about 75° F, depending on where you set your thermostat). Heat flows from warmer to cooler, so the air temperature drops, and the refrigerant...

How is energy heat created in the sun?

How is energy heat created in the sun? The core of the sun is so hot and there is so much pressure, nuclear fusion takes place: hydrogen is changed to helium. Nuclear fusion creates heat and photons (light). The amount of solar heat and light is enough to light up Earth's days and keep our planet warm enough to support life. How does sunlight heat a home? Direct Gain. In a direct gain design, sunlight enters the house through south-facing windows and strikes masonry floors and/or walls, which absorb and store the solar heat. As the room cools during the...

Which return vents should be open in summer?

Which return vents should be open in summer? Hot air rises and cool air sinks. Therefore, opening the right return vents in the summer and winter significantly improves the distribution of air by your forced-air system. You'll also enjoy more even heating and cooling throughout your home. In the summer, open your high returns and close the low ones. Should cold air returns be up high or down low? For optimal efficiency, it's ideal to have return registers installed. To ensure efficiency during the cooling season, your home should have high registers. High return registers draw hot air that rises...
