The answer to 'which is better water heater installation or' is that water heater installation is generally better than DIY water heater replacement. Professional installation by a licensed plumber ensures the job is done safely and up to code, while DIY work can be risky and lead to leaks, water damage, or even fire hazards if not done properly.
Some key benefits of professional water heater installation include proper sizing and placement of the new unit, ensuring all connections are secure and leak-free, and proper venting and electrical/gas hookups. Plumbers also have the right tools and expertise to dispose of the old unit safely. While DIY may seem cheaper upfront, the potential for costly repairs or replacements down the line makes professional installation the better choice for most homeowners.
