What homeowners in Herriman should know about tankless water heater
Tankless water heaters in Herriman solve the two biggest complaints about traditional tank water heaters: running out of hot water mid-shower (especially the 50-gallon tank in a 5-person Herriman household) and watching utility bills slowly drain off keeping 50 gallons of water hot 24/7 even when you're at work. Tankless heats on demand, lasts 20+ years vs 8-12 for a tank, and our Herriman's 20+ grain hard water means tankless owners benefit even more (no tank scale = no premature failure). But the install has more gotchas than most contractors warn you about: gas line may need upsizing from 3/4" to 1", venting needs PVC sidewall (not B-vent), and a softener loop becomes nearly mandatory at Herriman's hardness levels to keep the heat exchanger from scaling shut.

Tankless Water Heater FAQ — Herriman edition
How much does a tankless water heater cost installed in Herriman?
Most Herriman tankless installs run $3,800-$7,500 including gas line upsizing (if needed), PVC sidewall venting, condensate drain, electrical, and pulled permits. Variables: brand (Rinnai/Navien/Rheem $400-$900 spread), whether existing gas line is 3/4" needing upsize to 1" (+$650-$1,100), and whether you're adding a softener loop on the inlet (+$800-$1,400).
Will a tankless work for a large family in Herriman?
Yes — sized right. The right unit for a 4-5 person Herriman household running 2 simultaneous fixtures (shower + dishwasher) is a 199K BTU non-condensing or 180K BTU condensing model. Larger households or homes with body-spray showers need a 199K condensing OR a tankless + small storage tank combo. We size based on peak flow rate in GPM and Herriman's incoming water temp (40-45 degrees F in winter).
Do tankless heaters work well with Utah hard water in Herriman?
Only with proper maintenance. Herriman water at 20 grains/gallon will scale up a tankless heat exchanger and kill it in 4-6 years if you don't either (a) install a softener loop ahead of the heater, or (b) schedule annual descaling. We strongly recommend softener loop installs on every Herriman tankless — adds $800-$1,400 to the install but extends the heater life from 8 years to 20+.
How long does tankless installation take in Herriman?
Standard install replacing an existing tank: 1 day, 6-9 hours. New install with gas line upsize from 3/4" to 1": 1.5 days. Conversion from electric tank to gas tankless: 1.5-2 days (new gas line run, venting). Permit pull and inspection adds a couple days to the overall calendar but doesn't extend on-site time.
What maintenance does a tankless need in Herriman?
With a softener loop installed: annual flush/descale (we include in Service Partner Plan), inlet filter screen clean, condensate trap clean. Without softener: same plus 2x/year descaling minimum to avoid scale buildup. Either way: $99 flat-rate tune-up via our maintenance plan (the tankless-specific Service Partner tier is $169/visit).
