Water Heater Installation requires careful planning and professional installation. It involves working with natural gas, electricity and plumbing. Incorrect installations can lead to immediate and long-term problems.
Incorrectly sized water heaters can lead to poor energy efficiency, and frequent outages. The plumber must conduct measurements to ensure that the new water heater will fit your home’s needs. Click Here to learn more.
Water Heater Installation is a complex task that requires professional expertise and experience to complete. Attempting to do-it-yourself (DIY) could result in costly mistakes that impact the function, safety and compliance of your water heater. A DIY installation also poses risk of immediate or long-term damage to your home, not to mention possible personal injury. Many manufacturers require professional installation to qualify for their warranties.
Your Water Heater Installation cost will depend on the type of unit you choose, its location and the access to your plumbing system and electrical connection. Some models have a lower upfront price than others, but some have higher monthly operating costs due to higher energy consumption. Natural gas water heaters have the lowest initial price point, but they’re more expensive to operate than electric models.
If you’re upgrading from an electric tank-style water heater to a direct vent gas model, your installer will have to install new venting that brings combustion air outside and exhaust gasses away from the house. This can add an additional $500 to your overall installation cost.
Your water heater’s plumbing connections may be made with copper tubing, corrugated flexible metal connectors or flexible plastic tubing known as PEX. If your home uses PEX, review manufacturer’s literature to understand the specifics of working with this material before hiring a plumber for your project.
Some water heaters have a drain at the bottom to remove excess water and sediment from the unit. This is necessary to maintain your unit’s performance and extend its lifespan. It’s a good idea to have this drain piped to an adequate drain, which you should verify is in place and accessible for future maintenance.
Your plumbing and electrical system is typically connected to the water heater through a junction box on the top of the unit. Before starting work, check that the power is OFF at your circuit breaker or fuse box to reduce the risk of injury or fire. Upon completion, turn on the power and recheck connections for leaks. Consider insulating your hot water pipes to help save money on energy bills and extend the life of your new water heater.
Materials
If you are planning to install your own water heater, be sure you have the proper materials before starting. The list of supplies includes water and electrical wires, a new gas line if required by your local gas code, copper pipe fittings, soldering iron and pipe cutters. Some installations also require insulation. You may also need a carpentry kit if you must remove part of an existing wall or add part to an attic in order to install the water heater.
Make certain that the power to the water heater is OFF before working on it. Failure to do so could result in severe injury or death from electric shock. Check the wiring with a volt meter or circuit tester to be sure it is not energized. When working on an energized circuit, wear rubber gloves to protect yourself from shock. Install any plumbing and electrical wiring in an approved conduit to reduce fire risks. Then, remove the cover from the junction box on the top of the water heater and insert the conduit connector and power wires through the hole in the cover. Connect the home’s bare copper or green ground wire to the water heater’s green ground screw. Connect the hot and cold water pipes to the water heater with compression or soldering fittings. Use fittings appropriate for the type of pipes in your home (copper, PEX or CPVC). For ease of future removal for repairs, use dielectric unions to connect the water pipes to the water heater.
You must provide a sediment trap that keeps the sediment and natural gasses away from the water heater. If you are installing a gas water heater, you will need a gas supply line and a venting system that complies with your local codes. The gas supply line must be of sufficient size for the new water heater. Venting systems must have a draft hood to prevent condensation and be accessible for servicing.
Once the water heater is in place, a rigid foam pad and drain pan are needed for protection of the floor and to help maintain an even temperature. If the tank is located in an area prone to earthquake danger, seismic straps may be required.
Code Requirements
Your water heater is essential to the life of your home, so it’s important that it’s installed properly. If not, it could pose safety hazards and damage your home’s structure. There are several code requirements that must be met during the installation of your new or replacement water heater. These requirements include location, ventilation, and a temperature and pressure relief valve. The valve regulates the heat and pressure within your water heater to prevent explosions, and it also protects your house from fires caused by water leaks.
The location of your water heater must be in a space that allows for easy access for maintenance and repairs. The space must be free of any flammable or toxic materials, and the gas line must be located away from bedrooms, bathrooms, closets, and stairway landings. You must also have a clear path for water circulation to your water heater. The water heater must also be placed on a stable support surface and have a vent to the outside of your home.
The ventilation system of your water heater should be sized to match the size and BTU rating of your unit. The vent pipe should terminate not less than two feet above the roof, and an additional height is required if the roof has more than a six:12 slope. The vent pipe should be insulated and be made from metals such as galvanized steel or aluminum, and plastic is not permitted.
If your water heater is fueled by natural gas, you will need to install a thermal expansion tank as well. The expansion tank helps to reduce pressure in the plumbing system, and it is a requirement by the city of Richmond Heights. The tank must be connected to the hot and cold water lines, and it should have a shut off valve on the cold water line. It should also be labeled and have the highest allowable pressure marked on it. You must also install a temperature and pressure relief valve on your gas water heater. This valve is designed to protect your house from explosions caused by the sudden build-up of pressure.
Installation Location
While water heater installation varies by location and type of heater, the basic steps are generally the same. The first step is to shut off the power and water supply to the heater. For an electric water heater, this is done by switching off the circuit breaker. For a gas water heater, the valve at the incoming cold water line should be closed. You should also disconnect any hoses from the water heater. Once these tasks are complete, you can begin disassembling the heater.
You should also choose a location for the new water heater. Ideally, the heater should be located in a space that doesn’t require any major plumbing alterations and is accessible for future servicing. It is also a good idea to situate the water heater close to hot water applications, such as the kitchen and bathroom faucets. This will reduce the wait time for hot water and help you save energy.
Conventional water heaters are large, and they can take up a lot of space. Therefore, they are usually installed in a garage or basement. However, you should avoid installing them in a closet or attic, as these spaces can be difficult to access in the event of a leak. Additionally, if the water heater leaks, it could damage the lower levels of your home.
A tankless water heater is smaller and can be installed almost anywhere. This makes it a great option for homes with limited space or those that want to save energy by not heating the water they don’t use. However, if you’re planning on installing a tankless water heater, make sure that you consult the manufacturer’s instructions and your local codes to ensure that it is in compliance with all regulations.
Most areas require that gas water heaters have a flue vent to carry combustion fumes outside of the house. The location of this vent is critical because it must be located away from combustible materials and have at least 6 inches of clearance. In addition, the flue should be protected from rain and snow. If the venting isn’t in compliance with code requirements, dangerous carbon monoxide may build up in the house and cause illness or death.
