Which is better for a cold-climate home?

Both deliver 27 kW, so hot-water output is essentially the same. The Titan markets itself for 2 baths in cold climates with incoming water in the 50s. Pick on price and electrical setup, not climate.

The Ecosmart carries a 5-year limited warranty; the Titan listing states no warranty. That makes the Ecosmart the safer bet on paper, though both use copper and stainless components.

Is the Ecosmart worth the extra $54?

If the warranty and digital temperature control matter to you, yes. If your panel favors two 60 amp breakers and you want the lowest price, the Titan is the better value.

What electrical service do they need?

Both draw about 112 amps at 240 V. The Titan uses two 60 amp double-pole breakers; the Ecosmart uses three 40 amp double-pole breakers and calls for a 200 amp panel.

Can either go in an RV or mobile home?

The Ecosmart ECO 27 is rated for RVs and mobile homes. The Titan listing does not state that rating.

Do either qualify for ENERGY STAR?

No. Neither is ENERGY STAR certified, though both claim high efficiency and savings versus tank heaters.
