Gas vs Electric Water Heaters: Which Is Better for Denver Homes?

Replacing your water heater? One big decision stands out: gas or electric? Denver homeowners often wonder which is the smarter pick for our local climate and energy prices. Here’s a side-by-side look at how each type measures up, along with some pros, cons, and practical advice to help you decide.

What We're Comparing

Here’s what we’ll focus on:

• Upfront Cost
• Recovery Rate (Speed of Heating)
• Operating Cost
• Venting and Space Requirements
• Performance in Colorado Winters

Head-to-Head Comparison: Gas vs Electric Water Heater

Criteria	Gas Water Heater	Electric Water Heater
Upfront Cost	$1,200–$2,500 (includes installation) Extra expense if you need a new gas line	$800–$1,800 (includes installation) Needs enough electrical capacity
Recovery Rate	Heats quickly, good for bigger families or busy homes	Slower recovery, so heavy use can empty the tank
Operating Cost	Monthly costs are lower—natural gas is cheaper than electricity here	Tends to cost more to run in Colorado
Venting & Space Needs	Needs venting and combustion air, takes up more space	No venting required, so it fits in more spots
Winter Performance	Handles cold incoming water well—stays hot even in winter	May struggle to keep up when it’s freezing outside

Pros and Cons

Gas Water Heaters

• Pros:
  • Heats water fast
  • Lower bills (as long as gas stays affordable)
  • Works reliably through those cold Denver winters
• Cons:
  • Costs more upfront, especially if you need a new gas line
  • Installation needs more space and proper venting
  • There's a risk of gas leaks and it needs yearly checkups

Electric Water Heaters

• Pros:
  • Cheaper to buy and install
  • Easy swap when replacing an old unit
  • No venting—just plug in and go
  • Runs quietly
• Cons:
  • Heats up slowly and may not keep pace with heavy use
  • Monthly costs are higher with Colorado’s electric rates
  • Struggles a bit in the dead of winter

Switching Considerations

Thinking about switching from electric to gas? A new gas line might be required, which bumps up the price. Switching from gas to electric? You might need an electrical upgrade first. Either way, check your home’s setup before making the call.

What About Tankless?

Want endless hot water or a more efficient setup? Tankless water heaters (gas or electric) are worth a look. They cost more up front but can offer savings over time—and you won’t run out of hot water.
