Water Heater Installation, Repair & Replacement

A reliable water heater is essential for showers, laundry, dishes, and everyday household use. Baker Heating, Air Conditioning & Duct Cleaning installs, repairs, and replaces traditional tank, tankless, and heat-pump water heaters, with recommendations based on household demand, fuel source, available space, and budget.

Water Heater Options

Traditional Tank Water Heaters

Storage water heaters keep a set volume of hot water ready in an insulated tank. They are widely available, usually cost less upfront, and can be a straightforward replacement when the existing fuel source and connections are already in place.

Tankless Water Heaters

Tankless systems heat water as it flows through the unit. They take up less space and can provide continuous hot water within the unit’s flow-rate limits, but installation can require gas-line, venting, electrical, or plumbing changes.

Heat-Pump / Hybrid Water Heaters

Heat-pump water heaters move heat from surrounding air into a storage tank. They can use substantially less electricity than conventional electric-resistance models, but need appropriate installation space, airflow, condensate drainage, and ambient conditions.

Tankless vs. Traditional Tank Water Heaters

Traditional Tank Water Heater

Typical lifespan: About 10–15 years; DOE estimates average storage-water-heater life around 14–15 years.

Typical installed cost: Roughly $900–$1,800 nationally for many replacement projects, though size, fuel type, permits, and code upgrades can move the price higher.

Advantages:

  • Lower upfront cost in many homes
  • Familiar technology and widely available replacement options
  • Can handle several simultaneous draws until the stored hot water is depleted
  • Often simpler to replace like-for-like

Tradeoffs:

  • Uses floor space for the tank
  • Has standby heat loss because stored water is kept hot
  • Once the tank is depleted, recovery time is required
  • Tank corrosion or leakage becomes more likely as the unit ages

Tankless Water Heater

Typical lifespan: Around 20 years for gas tankless equipment when properly maintained; some units can last longer.

Typical installed cost: Roughly $1,400–$3,900 nationally. Converting from a tank system can cost more if larger gas piping, new venting, electrical upgrades, condensate drainage, or other modifications are needed.

Advantages:

  • No large storage tank
  • Heats water only when there is demand
  • Can provide continuous hot water as long as demand stays within the unit’s flow capacity
  • Longer typical service life than many tank models

Tradeoffs:

  • Higher upfront installation cost
  • Must be sized for simultaneous hot-water demand and incoming-water temperature
  • May require periodic descaling, especially with hard water
  • Gas models may require venting and gas-line upgrades

Cost figures above are broad 2026 national installation ranges for comparison only, not a Baker HVAC quote. Actual project cost depends on equipment size, fuel type, existing plumbing, gas or electrical capacity, venting, permits, and site conditions.

Which Type Is Better for Your Home?

A traditional tank model may make sense when:

  • Upfront cost is the primary concern
  • You are replacing a similar unit in the same location
  • The existing gas, electric, and venting setup already fits a tank model
  • Your household has short periods of high simultaneous hot-water demand

A tankless model may make sense when:

  • You want to free up floor space
  • You value longer typical equipment life
  • You want continuous hot water within the system’s flow-rate limits
  • The home can support the required gas, electrical, venting, and plumbing changes

Sizing Matters More Than the Label

For tank heaters, capacity and recovery rate matter. For tankless systems, flow rate and temperature rise matter. A system that is too small can struggle during peak use, while an oversized or unnecessarily complex system can raise project cost without adding useful performance.

Maintenance & Common Warning Signs

  • Rusty, discolored, or metallic-smelling hot water
  • Water around the base of a tank or visible plumbing leaks
  • Reduced hot-water capacity or inconsistent water temperature
  • Popping, rumbling, or other unusual noises from a storage tank
  • Tankless error codes, ignition problems, or reduced flow at fixtures
  • Frequent cycling, long recovery times, or noticeably higher operating costs

Maintenance needs vary by system. Tank heaters may benefit from sediment flushing and anode-rod inspection, while tankless units commonly require periodic descaling and filter cleaning based on water quality and manufacturer guidance.
