Water Heater Installation and Replacement Services
The right water heater installation depends on your fuel supply, space, and how many people need hot water at once. These are the systems and services we install.
Gas Tank Water Heaters
Gas tank heaters store hot water and recover quickly for busy households. We install standard and high-efficiency models, including Bradford White units, sized to your peak demand.
Electric Tank Water Heaters
Electric tanks fit homes and condos without gas service, and we match the tank size and circuit to your chosen unit.
Tankless Water Heaters
A tankless water heater heats water on demand instead of storing it. We install Rinnai, Noritz, and Navien systems with the gas line, venting, and condensate drain each unit requires.
Water Heater Replacement and Old Unit Removal
We drain, disconnect, and remove the old unit from your garage, closet, or utility area before installing the new one.
Tank to Tankless Conversions
Switching to tankless often requires upsizing the gas supply, so our gas line repair team handles that work within the same project.
Valves, Expansion Tanks, and Connections
Each install includes new supply connections, a temperature and pressure relief discharge line, a shutoff valve, and a thermal expansion tank where the system needs one.
Not sure if the old heater is finished? Our repair service can tell you if a fix still makes sense before you commit to a new unit.
What a Code-Ready Water Heater Installation Includes in Long Beach
Every water heater installation in Long Beach must meet two requirements: a City of Long Beach plumbing permit and California’s earthquake bracing law.
The City of Long Beach lists replacing a water heater in the same location, with the same size and type, as express plumbing permit work in its Express Permit Service bulletin (IB-058, revised July 2025), for units up to 200,000 BTU per hour. A change in location, size, or type, such as switching from a tank to a tankless heater, falls outside that express category.
State law adds a seismic rule. California Health and Safety Code Section 19211 requires all new, replacement, and existing residential water heaters to be braced, anchored, or strapped to resist falling or shifting during an earthquake, and home sellers must certify compliance to buyers. A heater that tips in a quake can tear its gas line or water connections loose.
At Mullen Plumbing, we include both requirements in the job. We confirm the permit path before installation, strap the new heater in its upper and lower thirds, and complete the gas, water, and vent connections so the installation is ready for city inspection.
Customers on Their New Water Heaters
An Old Leaking 75 Gallon Water Heater Replaced in Hours
Wendy Freijanes needed her old, leaking 75-gallon water heater replaced quickly. Our team installed the new heater in hours and, at her request, used small access holes and a camera to confirm the leak came from the heater, not the pipe behind it.
Confirming where a leak starts prevents a new installation from hiding a second problem in the wall. This check uses the same tools as our leak detection service. Read Wendy’s Google review.
Clean and Helpful Work on a Tankless Water Heater
Michael Brown has worked with Trevor for several years, most recently on a main bathroom shower update and a tankless water heater.
When a tankless upgrade happens with a bathroom project, planning both together keeps the fixtures and new heater working as one system. Read Michael’s Google review.
How Our Professional Water Heater Installation Works
Mullen Plumbing follows the same professional water heater installation sequence on every job. Sizing comes first because an undersized heater runs out and an oversized one wastes energy.
- Sizing and Site Check: We review household size, bathrooms, peak usage, fuel supply, venting, and installation space, then recommend a tank capacity or tankless flow rate.
- Upfront Quote: You approve the model and price before we begin any work.
- Old Unit Removal: We shut off gas, power, and water, drain the old tank, disconnect it, and remove it.
- Installation and Connections: We set the new heater and connect water lines, gas or electrical supply, venting, relief valve discharge, and an expansion tank where needed.
- Seismic Strapping: We brace the heater to meet California’s earthquake-bracing requirements.
- Testing and Walkthrough: We fill the system, purge air, check every joint for leaks, confirm temperature and venting, and show you the shutoff valve and settings.
A like-for-like tank replacement can often be finished the same day. Tankless conversions take longer because of the gas and venting work.
When to Replace Your Water Heater Instead of Repairing
Many Long Beach water heaters sit in garages, side yard closets, or tight utility spaces where slow problems go unnoticed for months. By the time water reaches the floor, the tank is usually beyond saving. These signs point to replacement.
Water Pooling at the Base
A leak from the tank body can’t be patched, so a new heater is the safe fix before the leak damages walls or flooring.
Rusty or Discolored Hot Water
Rust in the hot water only often means the tank’s interior is corroding from the inside.
Repeat Service Calls on the Same Unit
When an aging heater needs a new part every few months, that money is better spent on a reliable new system.
Hot Water That No Longer Keeps Up
A growing household, remodel, or new ADU can outpace your heater, and a properly sized replacement fixes the shortfall.

Water Heater Installation FAQs for Long Beach Homes
How do I know what size water heater my Long Beach home needs?
The right size depends on how much hot water your household uses at its busiest time, not just the number of bedrooms. For tank heaters, we look at the first hour rating, which measures how much hot water a unit can deliver in an hour of heavy use. For tankless units, we size by flow rate based on how many showers and appliances run at once. Bigger isn’t automatically better for either type since an oversized tank stores and reheats water you don’t use.
Is a tankless water heater a good fit for an older Long Beach home?
A tankless water heater can work well in an older Long Beach home once you check the gas supply, venting, and electrical needs. Many older homes were plumbed with gas lines sized for a tank heater, so a conversion may need a larger line. Tankless units also need a condensate drain on high-efficiency models and periodic descaling service to protect the heat exchanger. Those three checks separate a real tankless quote from an optimistic one, so ask any contractor what they found before you compare prices.
How long does a water heater installation take?
A like-for-like tank replacement can often be completed the same day. Tank-to-tankless conversions take longer because they involve gas line work, new venting, and wall mounting. Water heater work is permitted and inspected in California, and we schedule the inspection after the install so you don’t lose hot water. We provide a clear timeline with your quote so you know when to expect hot water again.
What happens to my old water heater during replacement?
We drain, disconnect, and remove your old water heater as part of the installation. You won’t have to move a heavy tank out of the garage or closet yourself. We clear the space before installing the new connections, and we also inspect the old shutoff valve, flex connectors, and drain pan, since those parts tend to fail shortly after a tank is replaced.
Do you install water heaters in Long Beach condos and apartments?
Yes, we install water heaters in Long Beach condos, apartments, and other multi-unit buildings. These jobs often involve tight closets, shared venting, or building rules about when work can happen. Access is usually the main constraint since a tank must fit through the same door and stairwell it came in by, which is one reason tankless suits some units better. We coordinate access with owners, tenants, HOAs, or property managers to keep the installation on schedule.
Do you offer water heater installation outside Long Beach?
Yes, Mullen Plumbing installs water heaters throughout Long Beach and nearby cities including Lakewood, Los Alamitos, Rossmoor, San Pedro, and Torrance. We apply the same sizing, strapping, and testing standards in every city we serve, including the seismic strapping California requires on tank heaters. Book online and include your city when you request a time.
