Quick Answer: The best Titan tankless water heater for most homeowners is the N-120 (SCR2, 11.8 kW/54A at 220V, up to 4.0 GPM at a warm inlet, roughly $220–$270) — it’s Titan’s most widely stocked model and fits a small home or single bathroom. For a mid-size 2–2.5 bathroom home, the N-160 (SCR3, 16 kW/66A, roughly $330–$380) adds output at the same rated flow. For a larger home or colder climate needing more simultaneous fixtures, the N-210 (SCR4, 21 kW/88A, up to 5.0 GPM, stainless steel case, roughly $440–$450) is Titan’s largest common residential unit. Titan is made by Niagara Industries and competes with EcoSmart on price at Home Depot and Ace Hardware — none of its models have WiFi, which keeps the unit cost down.
Last verified August 27, 2026: re-checked pricing across three retailers — Ace Hardware lists the N-120 at $269.99 (within the previously cited $220–$270 range), usatankless.com lists the N-160 at $333.00 and the N-210 at $441.00 (both within the ranges cited below). No price drift found; figures below hold.
Titan shows up in budget electric-tankless searches for the same reason EcoSmart does: it’s a no-frills brand sold at major big-box retailers rather than through HVAC contractors, so the unit price undercuts Rheem and Stiebel Eltron by a wide margin. The catch is that Titan’s model numbers (N-120, N-160, N-210) don’t map cleanly to a simple small/medium/large scale — the GPM ceiling barely moves between the N-120 and N-160 even though the kW rating jumps, and the real difference is how much cold-water headroom and simultaneous-fixture capacity each unit has. This guide ranks the three models people actually search for so you can match the right Titan to your panel and home size.

N-120 price per Home Depot listings (~$219–$265 depending on region/promotion); N-160 price per Ace Hardware's current listing ($379.99); N-210 price per Home Depot's current listing (~$446). Amazon pricing fluctuates and can run above or below these figures.
By the numbers
- 54 to 88 amps is the amp-draw range across Titan’s residential lineup (N-120 to N-210), per the manufacturer’s spec sheets — always confirm your panel has that much spare capacity before ordering, since undersizing the breaker is the most common install mistake with high-kW electric tankless heaters.
- 24–34% more energy efficient than a standard storage tank for a home using up to roughly 41 gallons of hot water a day, per the U.S. Department of Energy — the baseline efficiency case for electric tankless heating generally, independent of brand.
- 10 years is Titan’s warranty on water-carrying components for the SCR4 (N-210) line, per the manufacturer, versus a shorter 1–2 year components warranty on the entry SCR2 (N-120) line — a meaningful gap if you’re weighing the price difference between models.
1. Titan N-120 — Best Small Home / Single Bathroom
Titan N-120 SCR2 Electric Tankless Water Heater
- Titan's most widely stocked model at Home Depot and Ace Hardware — a digital LCD readout shows real-time output temperature, and a manual-reset thermostat guards against overheating.
- Sized by Titan for a 2-bathroom home in a warm climate, or a single bathroom/small apartment in a colder one — don't expect two showers running at once anywhere outside the South.
- Needs a dedicated 60-amp double-pole breaker and #6 gauge wire, which most panels have room for even without a full electrical upgrade.

The N-120 is the Titan most people land on because it’s the cheapest way into the brand and the model Home Depot and Ace Hardware both keep in stock. At 11.8 kW it draws far less power than the N-160 or N-210, which matters if your electrical panel is already close to capacity — a 60-amp breaker is a much smaller ask than the 90-amp breaker the N-210 needs. The tradeoff is flow: Titan rates it for a small home or single bathroom, not a house where two people might shower at the same time. If you’re replacing a similar-size unit from another brand, see our best electric tankless water heater roundup for how the N-120 stacks up against EcoSmart’s comparable ECO 11.
2. Titan N-160 — Best Mid-Size Home
Titan N-160 SCR3 Electric Tankless Water Heater
- Steps up to 16 kW (or a 208V/12 kW mode for buildings on that voltage) while keeping the same rated 4.0 GPM ceiling as the N-120 — the extra power buys more headroom in colder incoming water, not a higher top-line flow number.
- Titan rates the N-160 for a 2.5-bathroom home up to 2,500 sq ft in a warm climate — still climate-dependent, so expect less real-world capacity anywhere the groundwater runs cold.
- Digital display shows live power draw, voltage, and delivery temperature, and Titan backs the water-carrying components with a 10-year warranty on this line.
The N-160 sits in an odd spot on paper — it costs meaningfully more than the N-120 without raising the rated GPM ceiling — but the extra 4.2 kW is what keeps output stable when the incoming water is genuinely cold, not just warm-climate groundwater. That makes it the better pick for a mid-size home in a moderate climate that the N-120 would struggle with in winter, even though both units share the same 4.0 GPM spec sheet number. Confirm your panel supports a 70-amp double-pole breaker before ordering; see our tankless water heater electrical requirements guide for how to check.
3. Titan N-210 — Best Larger Home / Colder Climate
Titan N-210 SCR4 Electric Tankless Water Heater
- Titan's SCR4 line raises the rated ceiling to 5.0 GPM and adds a stainless steel outer case, versus the painted-steel housing on the SCR2/SCR3 lines — a durability upgrade Titan aims at larger residential and light commercial installs.
- Draws up to 88 amps at 220–240V, which typically needs a 90-amp double-pole breaker and heavier wire gauge — confirm your panel has that headroom before buying, since this is the biggest electrical ask in Titan's lineup.
- Backed by the same 10-year water-carrying-components warranty as the N-160, with the added durability of the stainless case for households running the unit harder.
The N-210 is Titan’s answer to a bigger or colder-climate home, and it’s the model that competes most directly with EcoSmart’s largest units and Marey’s ECO270 on price. The 88-amp draw is a real constraint — many existing panels need an electrician’s sign-off before adding a breaker that large — so budget for that possibility separately from the roughly $440–$450 unit price. For homes that need even more headroom than the N-210 offers, see our best whole house tankless water heater guide, where higher-output gas and electric options are covered side by side.
How to choose a Titan tankless water heater
- Small home or single bathroom, tight electrical panel: the N-120 — the lowest amp draw and the cheapest entry point.
- Mid-size 2–2.5 bathroom home, moderate climate: the N-160 — more power for cold-water headroom at the same rated GPM.
- Larger home or colder climate needing more simultaneous flow: the N-210 — Titan’s highest rated GPM and most durable case, at the cost of the largest breaker requirement.
- Panel can’t support Titan’s amp draw: consider a gas-fired option instead — see our best gas tankless water heater guide, which sidesteps the electrical-capacity question entirely.
- Comparing against other budget electric brands: Titan’s price point lines up closely with EcoSmart — see our best EcoSmart tankless water heater guide for that side-by-side.
The bottom line
Titan’s three residential models solve the same basic problem — hot water without a storage tank — at three different electrical-capacity tiers: the N-120 for a small home on a modest breaker, the N-160 for a mid-size home that needs more cold-water headroom, and the N-210 for a larger or colder-climate home willing to budget for a bigger panel allowance. None of them offer WiFi or app control, which is exactly why the unit prices undercut Rheem and Stiebel Eltron.
