Here’s something most plumbers won’t tell you: that high-power propane water heater you’re considering might actually use less fuel than your old tank model. Counterintuitive? Absolutely. But after a decade in this industry, I’ve seen homeowners cut their propane consumption by 25% within three months of switching to properly sized tankless units.
I once watched a family of six fight over morning showers for years. Their “solution” was cranking up a massive traditional heater. The result? Sky-high bills and still running out. When we installed a Westinghouse 120K BTU unit, their propane costs dropped 30% in the first quarter.
Why Continuous Hot Water Isn’t About Size
Most people think bigger tanks mean endless hot water. Here’s what I mean: a 50-gallon tank might hold 50 gallons, but once it’s depleted, you’re waiting 60-90 minutes for recovery. With tankless? The Westinghouse APOLO Performance delivers 5.1 gallons per minute indefinitely. That’s enough for two showers plus a running dishwasher simultaneously.
The myth-buster: Bigger storage tanks don’t solve high-demand problems. They just delay the cold shower by 20 minutes.
Thinking Like a Pro: The Flow Rate Framework
Here’s how I calculate real-world needs for clients:
- Standard shower: 2.0 GPM
- Kitchen faucet: 1.5 GPM
- Washing machine: 1.2 GPM
Add simultaneous uses, and suddenly that 5.1 GPM capacity makes perfect sense. The Westinghouse unit can handle three fixtures at once without temperature drops. And yes, I learned this the hard way early in my career – nothing teaches like a client calling from a cold shower.
The Smart Home Advantage You Haven’t Considered
Remember when adjusting water temperature meant trudging to the basement? The Westinghouse Wi-Fi capability changes everything. Last month, I helped a retiree set vacation modes from her smartphone while visiting grandchildren. No more heating water for an empty house.
Here’s what most installers miss: that ±1°F temperature stability matters more than people realize. Ever jumped in the shower when someone flushes? With traditional heaters, you get scalded. With the advanced flow servo in this unit? You wouldn’t even notice.
A restaurant client was losing customers over inconsistent hand-washing temperatures. We installed two Westinghouse units in series. The result? Perfect temperature consistency across all seven sinks, and they saved $400 monthly on energy.
The Marathon Runner Analogy
Think of traditional water heaters as sprinters – explosive energy then complete exhaustion. The Westinghouse 120K BTU unit? It’s the marathon champion. Steady, consistent performance that doesn’t quit when you need it most.
This analogy hits home when you consider most households use hot water in waves: morning rush, evening cleanup. The tankless approach matches this natural rhythm perfectly.
Installation Insights From the Front Lines
That “professional installation recommended” note? It’s not corporate CYA. I’ve seen DIY attempts that voided warranties and created safety hazards. The 3/4″ NPT connections make integration straightforward, but the venting and gas line requirements need expert eyes.
Here’s a pro tip: always install isolation valves. When maintenance time comes (and it will), you’ll thank me. The alternative involves shutting down your entire water system.
| Consideration | Traditional Tank | Westinghouse 120K BTU |
|---|---|---|
| Energy Waste | Standby heat loss 24/7 | Only when water flows |
| Space Required | 16+ square feet | Mounts on any wall |
| Lifespan | 8-12 years | 15-20 years |
The Freeze Protection Most People Discover Too Late
That freeze protection system isn’t just marketing fluff. Last winter, a client’s basement hit -10°F during a power outage. Their traditional heater burst, causing $15,000 in water damage. The Westinghouse unit next to it? Completely fine once power restored.
But here’s the crucial detail many miss: the freeze protection requires power. No electricity, no protection. That’s why the manual emphasizes draining during extended cold spells.

Your Reality Check
Does every home need 120,000 BTUs? Honestly? No. But if you regularly run multiple showers while doing laundry, or operate a small business with high hot water demand, the question becomes: can you afford not to have this capacity?
Picture your busiest morning. Kids showering, coffee brewing, dishwasher running. Now imagine perfect temperature consistency through it all. That’s the difference between coping and thriving.
Next Steps That Actually Make Sense
First, audit your current hot water usage for one week. Count simultaneous uses and note temperature fluctuations. Second, get three quotes from licensed propane specialists – not general handymen. Third, ask about the Westinghouse warranty registration process (those 5 years on heat exchangers are gold).
The industry is shifting toward modulation over brute force. The Westinghouse APOLO’s self-modulating technology represents where all water heating is heading. Getting there now means skipping a generation of obsolete technology.
Still wondering if tankless is right for you? Ask yourself this: when was the last time you truly enjoyed your home’s hot water system? If the answer doesn’t come quickly, maybe it’s time for a change.
