When a water heater fails, you usually find out the cold way — mid-shower, or by stepping into a puddle in the garage. Houston Flow Plumbing installs and replaces water heaters across the metro, often the same day, with licensed plumbers who size the unit correctly, pull the right permit, and bring everything up to current Texas code. Whether you want a like-for-like swap or an upgrade, you'll get a flat price in writing before any work starts.
We install every common type. Traditional tank heaters (typically 40- and 50-gallon for Houston homes) remain the most affordable upfront and are a straightforward replacement. Tankless units heat water on demand, never run out, and last longer — a strong fit for larger Memorial or Katy homes and anyone tired of waiting on a recovery cycle. If you're weighing the two, our tankless water heater page breaks down the trade-offs, and our plumber will give you a straight recommendation based on your home's size, gas supply, and hot-water demand rather than just selling the priciest option.
Houston is genuinely tough on water heaters. Our hard, mineral-heavy water leaves sediment in tank bottoms and scale on heating elements, which is why local units often need replacing sooner than the manufacturer's estimate. Pairing a new heater with a water softener is one of the smartest ways to protect your investment and extend its life. We'll flush and inspect the new setup, replace worn shutoffs and flex connectors, and make sure the T&P valve, expansion tank, and venting all meet code — details that cut-rate installers skip.
Permits and code aren't optional, and they protect you. We pull the proper City of Houston permit, install drip pans and drain lines where required, and ensure gas and venting are done safely on gas units. That matters for resale and for insurance if anything ever goes wrong. Every install is performed under Texas Master Plumber License #M-41872, and it's backed by the same 4.9-star service that's earned us more than 2,030 reviews.
On pricing: a standard tank water heater installed in Houston typically runs $1,400 to $2,800, while tankless installations generally fall between $3,500 and $6,000 depending on gas line and venting needs. We offer GreenSky financing so a sudden failure doesn't blow your budget, and if your old unit is leaking now, our 24/7 team can handle it tonight. If your heater can still be saved, we'll tell you that too — see our water heater repair options. Call (713) 555-0164 for a free, no-pressure assessment.
