Why is a permit needed for water heater replacement?

Most people think they only need a permit for a new house or major home renovations. However, this is not always the case. The permit for replacing or installing a water heater is not to get permission.

The permit ensures that the installation or replacement will be inspected once it has been completed. Many jurisdictions in the US require a permit because of the dangers involved in installing a new water heater or replacing an old one.

For example, gas-powered water heaters require a connection to the gas line. If this line is not installed properly, it is a fire hazard to the house and community.

An electrical water heater needs wiring and a breaker to function properly. It is important, therefore, that all electrical components are correctly installed.

Additionally, water heaters need a temperature and pressure relief valve. Without this, the pressure could build up and cause an explosion.

Water from the water heater could leak and destroy surrounding structures. Carbon monoxide can leak into your house and cause you and your family harm.

A plumbing inspector can identify potential problems and address them before they can be a hazard for you, your family, and your home.

These are some of the reasons why an experienced plumber is required to properly install a water heater. The upside of this is that most professional water heater installers can get the permit for you for a hassle-free experience.

Where should a water heater be placed in a house?

Like water heater replacement permits, state and national regulations specify locations where to install water heaters. Most of these regulations require that water heaters are installed against an external wall of the house.

This requirement is one of the reasons why most water heaters are installed in the basement or garage. Installing a water heater against an external wall is a good idea to easily make room for the flue.

Other Considerations for Water Heater Placement

Another factor to consider is to place your water heater close to the faucets or showerheads where hot water will be accessible. Hot water moves from the hot water tank, and the water rapidly cools as it travels through the pipes to where it will be used.

The farther away the faucets are from the water heater, the more energy will be wasted along the way and the harder the water heater needs to work to provide the needed amount of hot water. Placing the water heater as close as possible to your kitchen and bathrooms helps save energy.

Drainage

In addition to installing your water heater on a level floor, it should also be installed close to a floor drain in case there are water leaks. The relief valve of a water heater also needs to go to an open drain.

Most regulations allow the installation of a drain pan under the water heater because installing it close to a floor drain isn’t always possible.

The drain pan should be at least two inches deep. It should also be at least two inches longer and wider than the water heater dimensions. Install a pipe to connect the drain pan and the drain for adequate water disposal.

Power & Insulation

Most water heater manufacturers prefer to have water heaters installed close to power sources so that the wiring can be as short as possible. Pipes and wires should be insulated so that damage from leaks will not short out the electrical system of your house.

Can I install my water heater outside the house?

How much would it cost to install a 50-gallon water heater?

A new 40- to 50-gallon water heater can cost anywhere from $330 to $2,000 for the unit.

In addition, the installation labor can cost $200 to $1,000. The installation can take two to six hours to complete for most tank-type units. The installation cost for gas water heaters is normally $100 to $700 more than the electric water heater installation cost.

Annual operating costs for tank-type units are $225 to $580, while tankless units have an operating cost of $150 to $535.

Can a water heater be enclosed?

Water heaters are often installed in the basement. However, if the basement is repurposed, the water heater can be left in plain view and diminish the room's appearance.

The water heater can be enclosed with walls and turn the enclosed area into a utility closet. So, would a wall four inches away from the water heater be sufficient?

Concrete Network explains that the enclosed space of water heaters should remain accessible without removing any permanent construction. This is to ensure that the water heater can be easily inspected, serviced, repaired, and replaced.

If you have a gas water heater, the enclosure should have access to a sufficient amount of fresh air for the fuel to burn efficiently.

In addition to having adequate space, you’d need to install a double door on one of the walls. Double doors ensure that you have enough room to remove the old water heater out of the enclosure and bring in a new one.
