Water Heater Installation
If your morning shower suddenly turns cold — or your water heater’s making more noise than it should — it may be time to consider a replacement.
At Onyx Plumbing & Gas, we specialize in expert water heater installation that keeps your home running reliably and efficiently. Whether upgrading to a modern, energy-efficient model or replacing a tank that just gave out, our licensed, St. Louis Park-based plumbers handle every detail of your installation with care and precision!
Today’s water heaters offer better performance, greater energy efficiency, and longer lifespans than the models of even 10 years ago. From high-efficiency tank systems to tankless on-demand options, we install quality water heater systems built to handle Minnesota’s seasonal swings and your family’s daily needs.
We partner with trusted brands, offer flexible venting and sizing solutions, and make sure every install meets the code. You’ll also get a 1-year labor warranty with every installation — plus transparent pricing and no gimmicks.

It’s not always obvious when your water heater is on the way out. But catching the signs early can prevent a complete breakdown or even costly water damage.
Here are the common red flags that it’s time to call Onyx Plumbing & Gas for a new install:
If your water heater is more than 8–12 years old, it’s already running on borrowed time.
Older systems are more prone to failure, leaks, and inefficient heating. Replacing it now can save you money and hassle later.
Are you running out of hot water too quickly? Dealing with long reheat times?
A newer system will provide consistent hot water — and better energy savings — with fewer performance dips.
Rust on the tank, pooling water underneath, or discoloration around fittings are signs of corrosion and internal wear.
These aren’t cosmetic issues — they’re early indicators of potential failure.
Popping, banging, or sulfur-like smells from your water heater usually point to sediment buildup or bacterial growth.
If flushing doesn’t fix it, replacement may be your best option.
