Water heater installation includes a variety of steps. Depending on the type of unit being installed, it may require connecting electrical or gas lines.
First, shut off the water supply to your old water heater by opening the circuit breaker or pulling the fuses. Then, drain the water from your water heater. Go to https://www.mrheatfurnaceorillia.ca to learn more.
Installation Location
Many homeowners don’t realize that the location of a water heater can have significant impacts on the unit’s efficiency, longevity and safety. Whether you have a tank or a tankless model, it’s important that you follow the instructions from your manufacturer to make sure that your installation is safe and complies with local building and plumbing codes.
If you have a traditional water heater with a tank, it’s important to choose a location that has plenty of room for the unit and the associated components. You also want to ensure that the area has easy access for maintenance. Measure the space in your home to make sure that the unit will fit, and consult the product manual for specific dimensions and clearance requirements.
In general, tank water heaters take up a lot of space. However, if you have a smaller home, a tankless model may be able to accommodate the unit in a closet or even underneath the sink. Tankless models are also much more energy efficient, as they don’t use gas or electricity to keep hot water flowing through your pipes.
Another consideration when choosing a location is ensuring that it has easy access to your home’s hot and cold water lines. It’s essential to have clear, unobstructed pathways from the water lines to the unit, as well as an accessible drain valve and shut-off valve. You’ll also need to maintain the recommended distances from combustible materials specified in the product manual to avoid fire hazards.
You’ll also want to consider the climate where you live when choosing a location for your new water heater. If your home is located in a colder region, you’ll want to install the unit in a garage or other sheltered outdoor location to protect it from freezing weather.
If you live in an earthquake-prone region, your water heater may require seismic straps during installation to help keep the unit upright and secure in case of an earthquake. Talk to your local water heater installers about the code requirements for your area and ask them to install these straps during your installation.
Installation Time
Water heaters are large, heavy units and the installation process takes a considerable amount of manual labor. Professional plumbers typically have the equipment to lift and move them. They also have access to tools and equipment that aren’t available to homeowners, including electrical cords and gas hoses.
Prior to installation, a licensed plumber will assess your home and plumbing system to determine the best type of water heater for your needs. This consultation can be done over the phone or in person, and will help you decide between a tank or tankless water heater. It will also help you set a timeline for the installation.
During the installation, your licensed plumber will drain and disconnect your old water heater. Then, they’ll connect the new unit to your home’s water lines and gas or electricity supply, as applicable. This includes insulating and sealing the connection points to prevent leaks and ensure efficiency.
If you’re replacing a tank with a similar model, the entire installation can take two to three hours. This includes about an hour for disconnecting and removing the existing water heater, and about an hour to install the new one. If you’re switching to a tankless water heater, the installation process will be longer, as your licensed plumber may need to create new air vents or install new power lines.
Once the water heater is in place, your licensed plumber will make sure the connections are snug and secure. They’ll also test the unit to make sure it operates correctly and is safe to use. They’ll also add safety features, such as pressure and temperature relief valves.
To get started with your water heater installation, turn off the water supply at your home’s main shutoff valve or at the isolation valve on the incoming cold-water line. Then, disconnect the water heater’s electrical wires at the junction box, and remove the gas line from the unit if it’s a gas model. If the water heater is being installed indoors, it’s a good idea to install insulation around the cold and hot water pipes, especially if they’re exposed to freezing temperatures or are in an uninsulated area.
Materials
Water heaters come in a variety of materials to accommodate different local code and plumbing requirements. The choice of water heater parts and materials will also influence installation cost and ease of use. High-quality units, parts and materials help to minimize risks of leaks or malfunctions. Depending on your municipality, you may have to apply for a permit and schedule an inspection to ensure the proper and safe water heater installation.
Before beginning your water heater installation, turn off the power to your unit at the circuit breaker and use a voltmeter or circuit tester to ensure that all the electrical connections are completely disconnected. Attempting to work on an energized circuit can cause serious injury or even death from electric shock.
Remove the cover on the electrical junction box at the top of your new water heater and disconnect the wire connectors from the appliance service wires. Then find the green ground screw on the water heater and unscrew it to release the ground wire. Lastly, remove the electric cable and wire nuts that connect your home’s two power wires to the water heater using a pair of pliers or pipe wrench.
Now you can begin hooking up the new water heater. First, install the cold water supply line, a ball valve and a pressure relief valve. Next, connect the hot water pipe with compression fittings that match your existing piping, such as PEX or CPVC (do not use iron pipes). If you plan on installing rigid CPVC or PB plastic tubing, then you will need to use “transition unions” between the metal heater threads and the plastic piping to distance the unions from conducted burner heat.
For a gas water heater, follow the manufacturer’s guidelines and your local codes for venting. Most newer gas heaters with a capacity of 55 gallons or more cannot be vented into a chimney, but must be vented through a double-chambered vent pipe. Most of these vent pipes are made from non-metallic plastic to avoid rusting the inside of your house’s structure. Now you can install the flue hood and the gas exhaust pipe that vents out of your home, connecting both with sheet metal screws.
Safety
The water heater installation process involves handling electricity and hot elements, which poses safety risks. Make sure that you have the right safety equipment for your job to minimize injuries. This includes gloves, eye protection, and durable footwear. Also, hire a licensed electrical worker to do the wiring for you if necessary. This will prevent faulty wiring, which could lead to fires or electrocution.
Water heaters require proper ventilation to avoid carbon monoxide buildup, which can be dangerous if levels get high enough. It is also important to install the correct temperature pressure relief valve and to adhere to regulations for venting.
A discharge pipe from the relief valve should be as wide as the outlet and made of a material that is suitable for water pipes. It should be positioned within 6 inches off the floor or receptor and not blocked by tee fittings or blockages. For gas water heaters, the vent should be a minimum of 6 inches from combustible materials. A sediment trap should be installed to keep debris and contaminants out of the venting system.
It is also important to read governmental safety bulletins about water heaters. These will let you know about new standards, potential hazards, and tips for using your water heater. For example, a faulty pilot light will stop the water heater from turning on and supplying heat, and a gas valve that malfunctions could cause an explosion or lack of hot water.
Before starting the installation process, disconnect the existing water supply and vent pipes from the old tank. This will help you remove the old heater safely and minimize the risk of leaks during the removal process. If possible, use a hand truck or a helper to lift the old water heater. This will be much easier than carrying it by yourself. Place the new water heater on cinder blocks or concrete blocks that are the same size as the heater to minimize the risk of it shifting during the installation. It is also important to align the new water heater with the cold and hot water lines so that they are pointing in the same direction.
