A water heater lasts a decade or more, so a little thought at replacement time pays off for years. Three questions cover most of the decision: tank or tankless, what size, and how to handle Colorado's hard water.
1. Tank or tankless?
A tank keeps 40-50 gallons hot and ready; it is cheaper upfront and simple to replace. A tankless unit heats on demand, never runs out, and saves standby energy, but costs more upfront. Our companion piece on tankless vs. tank breaks the tradeoffs down in detail.
2. Sizing
For a tank, size to your household's peak demand so you do not run out mid-shower — or overpay to keep water you never use hot. For tankless, sizing is about flow rate: how many fixtures might run at once. A large household running multiple showers and appliances simultaneously needs a properly sized unit or more than one.
3. The Colorado hard-water factor
Front Range water is hard, and that mineral scale is hard on every water heater — see how hard water wrecks water heaters. Pairing your new unit with water treatment and flushing it periodically meaningfully extends its life.
What else matters
- Fuel type: Gas and electric models differ in operating cost and installation needs.
- Warranty and installation: A quality unit installed correctly outlasts a premium unit installed poorly.
- Financing: For tankless or larger jobs, ask about financing.

Frequently asked questions
What size water heater do I need?
For tanks, it depends on household size and peak demand — a common range is 40 to 50 gallons, larger for big households. For tankless, sizing is about flow rate and how many fixtures run at once. Proper sizing avoids running out of hot water or overpaying.
Is tankless worth it in Colorado?
It can be — tankless offers endless hot water and lower standby energy use, but costs more upfront and needs periodic descaling because of our hard water. Whether it is worth it depends on your household size, habits, and budget.
How does hard water affect a water heater?
Front Range hard water leaves mineral scale that insulates heating elements and shortens the unit's life. Pairing any water heater with water treatment, and flushing it periodically, protects your investment.
