1. What are the different components of a water heater and what are they for?

The tank type water heater is the most common. Components include the flue pipe which is used to evacuate the deadly gasses which contain carbon monoxide created upon combustion. The cold water shut off valve which shuts the cold-water supply down when a heater needs to be drained or replaced. The draft diverter is a fitting on the end of the flue pipe that gather the gasses to be safely evacuated into the flue and then to the outside. The temperature and relief valve allow excess heat or pressure to be released from a hot water tank so it doesn’t explode. The overflow pipe which is attached to the T&P valve and that if the T&P valve releases excess heat/steam the pipe allows the water to drain safely away from the heater. The hot water outlet is the pipe that drops down into the heater that allows the hot water to exit the heater and enter the potable water supply in a home or business. The anticorrosion anode rod is installed at the top of the tank and are generally made of magnesium or aluminum with a steel core. The dip tube allows the cold water to enter at the bottom of the tank where there is heat rising to the top always self-circulating. Insulation wraps the metal tank to keep the heat in the tank. The drain valve is installed at the bottom of the tank and allows the tank to be drained down. The thermostatic control valve controls how hot the water gets in a water heater. The main burner ignites natural gas or propane and heats the tank. The thermocouple is a small electric generator made of two different metals that are firmly joined and is used as a safety device for gas powered appliances.

2. What are the advantages of an in – line water heater?

An in-inline water heater is also known as tankless water heater and can use up to 50% less energy. They reduce costs because it requires less of the storage tank. One of the advantages is this in-line water heater provides hot water immediately verses waiting for the stored water in the water

3. What are stack vents for?

Stack vents are used to allow air to the plumbing system and provide an outlet for sewer gasses. It is typically a terminal for other pipes.

4. Discuss two or more reasons for venting a plumbing system.

The plumbing vent, also known as vent stack, is used in residential plumbing to regulate air pressure in the plumbing system. It removes gas and odors. It also allow fresh air into the plumbing system to help water flow smoothly through the venting pipes.

When a plumbing vent stack is blocked then negative pressure will build up in the plumbing system creating problems as slow drainage or bad odors.

1.      What are the different components of a water heater and what are they for?

 As we know, water heaters are house appliances that their main purpose is to heat water and distribute it throughout the house/building. As stated in chapter 6 of the textbook, there are two types of water heaters, gas and electric, and their components which are built to resist high pressure and temperatures are the following;

 Gas Water Heater

Main Burner – the utilization of liquified petroleum gas (LPG) or natural gas to make a combustion to produce heat.

T&F Relief Valve – designed to protect pressure vessels not exceeding their design limits.

Storage Tank – water container

Top Cover – which consist of three openings, cold inlet which is cold water coming in from the source to the inside of the tank, draft hood which is used to vent out any gases from the burner out the house and the hot water outlet which is heated water that will supply the rest of the fixtures.

Drain Valve – design to flush/drain any particles that have built up at the bottom of the tank, which could cause damages to the heater.

Thermostatic Control – design to control the temperature of the water inside.

 Electric Water Heater

1.   Main Burner – heat is generated by the flow of electricity through a resistance wire.

2.   Immersion Element – heating device that transfer its energy to the water inside the tank once in contact with it.

3.   Dip Tube – distributes cold water from the cold-water inlet to the bottom of the tank via             a tube

2.       What are the advantages of an in – line water heater?

A tankless water heater provides hot water in seconds and can be shared simultaneously throughout a household or facility. By not having to let the water run until it begins to heat, the tankless heaters are energy and water efficient.  The expected life cycle of these tanks is about 20 years, reducing costs and waste.

3.       What are stack vents for?

Stack vents provide venting and is a direct extension from a waste stack that must reach the outside air. The purpose is to vent sewer gas and allow toilets and drains to work properly. Stack vents help prevent gas and particle blockages that could cause foul odors or result hazardous to your health.

2.     What are the advantages of an inline water heater?

The main advantage is that they eliminate the extra cost of keeping 40 to 50 gallons of water hot in a storage tank, so you waste less energy. They’re more compact than a standard water heater and mount on a wall.

3.     What are stack vents for?

A stack vent is the extension of a soil or waste stack above the highest horizontal drain connected to the stack. A vent stack is a pipe provided specifically to prevent  trap siphonage and  backpressure 

4.     Discuss two or more reasons for venting a plumbing system.

Vent pipes ventilate building sanitary drainage systems and prevent trap siphonage and backpressure. Air circulation within drainage systems allows wastewater to flow freely through the pipes and also removes objectionable gases from the sanitary drainage system
