Install Your New Water Heater Correctly

Water Heater Installation in Salem for homes replacing a failed unit or upgrading capacity

All Set Plumbing LLC handles water heater installation in Salem, Oregon for homeowners replacing a unit that has failed, upgrading to a larger tank to meet increased demand, or switching fuel sources during a remodel. A properly installed water heater delivers years of consistent performance without leaks, code violations, or efficiency losses.


We size the new unit based on your household's actual hot water usage, the number of bathrooms, and whether you run high-demand appliances simultaneously. Installation includes removing the old water heater, disposing of it according to local guidelines, running new supply and discharge lines if required, setting the new unit in place, and making all gas, electric, and water connections to current Oregon plumbing code. We install code-compliant expansion tanks on closed systems, verify proper venting on gas models, and set the temperature to a safe and efficient level before we leave.

How We Size and Install Your Unit

You provide details about your household size and hot water usage patterns, and we calculate the first-hour rating needed to meet peak demand. A typical three-person household with one bathroom may only need a 40-gallon tank, while a five-person home with two bathrooms and a high-efficiency washing machine may require a 50-gallon or larger unit. We account for recovery rate, which varies depending on whether the unit is gas or electric.


Once the new water heater is installed, you will have a full tank of hot water within an hour on gas models or within two hours on electric models. The unit will maintain consistent temperature, refill and reheat efficiently between uses, and operate without the leaks, rust stains, or temperature swings that indicated your old unit had failed.


We install earthquake straps where required, use dielectric unions to prevent galvanic corrosion between dissimilar metals, and verify that the temperature and pressure relief valve drains to an appropriate location. Installation does not include structural modifications, dedicated circuit upgrades beyond standard replacement scope, or gas line extensions that exceed fifteen feet from the existing connection point.

What Homeowners Ask About Water Heater Installation

When replacing a water heater, homeowners want to know how the process works, what it costs, and whether they should change fuel types or capacities during the installation.

How long does water heater installation take?

A standard replacement on an existing gas or electric line takes between two and four hours. If we need to run a new vent, upgrade electrical service, or relocate the unit, the installation takes longer and may require a separate electrical or gas permit.

What size water heater do I need?

You need a unit with a first-hour rating that matches your peak hour demand. We calculate this based on the number of people in your home, bathroom count, and appliance usage during the busiest part of the day.

Can I switch from electric to gas or gas to electric?

Fuel conversions are possible but require either a gas line extension or a dedicated 240-volt electrical circuit, along with proper venting for gas units. In Salem, we handle both fuel types and can walk you through the cost difference and permit requirements.

What is the difference between a tank and tankless water heater?

A tank water heater stores and heats a set volume of water and is ready to deliver hot water immediately. A tankless unit heats water only when you open a tap, providing endless hot water but requiring higher upfront cost and sometimes a larger gas line or electrical service.

How long will my new water heater last?

Most tank water heaters last eight to twelve years depending on water quality, usage, and whether you drain sediment annually. Units installed with expansion tanks and proper anode rod maintenance tend to last toward the higher end of that range.
