A tank water heater costs less upfront and is simpler to replace in most Lakewood garages. A tankless heater saves space, never runs out of hot water and can be more efficient, but usually costs more to install because of gas line and venting changes. The right choice depends on your household's hot-water use, budget and how long you plan to stay.
Side-by-side
| Factor | Tank | Tankless |
|---|---|---|
| Upfront cost (published range) | $600–$3,100 installed (HomeGuide, 2026) | $1,400–$5,600 installed (HomeGuide, 2026) |
| Hot water supply | Limited to tank size | Continuous, limited by flow rate |
| Space | Large footprint | Wall-mounted, compact |
| Efficiency | Standby losses | DOE Building America: roughly 33% gas savings, varying with use |
| Gas line | Usually existing line | Often needs upsizing in older homes |
| Venting | Existing vent often reusable | New vent type usually needed |
| Maintenance | Periodic flushing | Periodic descaling |
| Typical lifespan | Roughly 8–12 years | Often longer with maintenance |

Which is right for you?
- Choose a tank if you want the lowest upfront cost, a quick like-for-like swap, and your household's hot-water use is moderate.
- Choose tankless if you run out of hot water often, want to free up garage space, plan to stay long enough for efficiency savings to matter, and your gas line can be upsized.
- Consider a heat pump tank if you have space and electrical capacity, and want high efficiency.

Many Lakewood homes from 1950–53 have garage heaters and smaller gas lines. Lakewood city water is groundwater from deep wells, so descaling matters for tankless units. See Lakewood groundwater. Garage and outdoor heaters start with planning review.

What should you ask on the call?
- Which option fits the condition and layout of my home, and why?
- What extra work would each option need, such as gas line, venting, electrical, drywall or a permit?
- What's the expected lifespan and maintenance for each?
- What warranty comes with the parts and the labor?
- Can I get prices for both options, itemized the same way?
The right answer often depends on things only a site visit can show, like pipe condition, gas line size and available space. A good provider will explain the trade-offs rather than push one option.
What about Lakewood homes affects this choice?
Most Lakewood houses were built between 1950 and 1953, according to the City of Lakewood's history. They're mostly single-story homes on concrete slabs, with the water heater in a garage, closet or outdoor shed, and many still have some original galvanized supply pipe and early sewer laterals. That shapes the options: attic routing makes repipes simpler, garage heaters raise placement and permit questions, older gas lines may need upsizing for tankless units, and old laterals may not suit aggressive cleaning. The Lakewood Building and Safety permits page lists which projects often need a permit.
