Right-sizing your water heater
We ask about your home's size, number of occupants, and hot water usage to recommend the right tank size or tankless capacity. Proper sizing prevents cold showers and wasted energy.
Water Heater Installation
New water heater installation in Dallas & DFW — done right the first time.
Whether your current water heater is failing or you're upgrading to a more efficient model, 448 Plumbing handles the full installation process: sizing, permitting, installation, code checks, and haul-away. We install gas, electric, and tankless units designed to match your home's needs.
Code-compliant installation
Our technicians follow local codes for venting, gas line connections, electrical requirements, pan and drain setup, and seismic strapping where applicable. We obtain permits when required and leave your space clean.
Old unit removal
We disconnect, drain, and haul away your old water heater so you do not have to figure out disposal. Before we leave, we verify proper operation and show you how to use any new controls.
Tank vs. tankless — which is right for you?
Tank-style heaters are often more affordable up front and work well for many homes. Tankless heaters cost more initially but can offer endless hot water and improved efficiency when sized and installed correctly. We'll walk you through real numbers for your household so you can choose with confidence.

Water heater installation FAQ
How long does water heater installation take?
Most standard replacements take 2–4 hours once we arrive, depending on access, venting, and any code upgrades needed. More complex tankless installs can take longer.
Do you provide the water heater or can I supply my own?
We can provide and install recommended models that we trust, or install a customer-supplied unit as long as it meets local code requirements. We'll explain pros and cons of each approach.
Will my new water heater be more efficient?
Newer heaters are generally more efficient than older units, and high-efficiency or tankless options can reduce energy use further. We'll estimate potential savings based on your usage.
Can you upgrade me from tank to tankless?
In many homes, yes. We'll evaluate gas line capacity, venting, and electrical needs to determine what upgrades are required and provide a clear, itemized estimate.
