Your water heater is one of the hardest-working appliances in your home, and one of the most overlooked. It’s easy to take hot showers and clean dishes for granted until, one morning, you’re standing under a stream of icy water wondering, “Is this thing done for?”
If your water heater is acting up, leaking, or just getting older, it may be time for a replacement. But how do you know for sure? And what type of water heater is best suited for Iowa homes, with our cold winters and high demand for reliability?
At Holt Plumbing & Heating, we’ve been helping Central Iowa families with water heater installation, repair, and replacement for over 75 years. Here’s what you need to know to make the right call for your comfort and your home.
Signs It’s Time to Replace Your Water Heater
1. It’s Over 8–10 Years Old
Most traditional tank-style water heaters last around 8 to 12 years. After that, they become more prone to:
- Leaks
- Inefficient heating
- Corrosion
- Higher energy bills
If your unit is approaching a decade (or older), it’s a good idea to start planning for replacement, before it leaves you with a cold shower or worse, a flooded basement.
2. Inconsistent Hot Water
Are you running out of hot water faster than you used to? Does the water fluctuate between hot and lukewarm? These are signs that the heating elements or tank insulation may be failing.
3. Rusty or Discolored Water
If your hot water looks brown, rusty, or has a metallic taste, it could be a sign of:
- Tank corrosion
- A failing anode rod
- Rust inside aging pipes
Either way, it’s time for a professional inspection, and likely, a new system.
4. Strange Noises
Popping, rumbling, or banging sounds from your tank? That’s often due to sediment buildup, which hardens over time and causes the water heater to work harder (and louder).
5. Visible Leaks or Water Around the Tank
Even a small amount of water collecting at the base of your tank could be the early sign of a crack or internal leak. Ignoring it can lead to water damage and mold growth.
Types of Water Heaters: What’s Best for Iowa Homes?
Whether you’re replacing a broken system or upgrading for efficiency, choosing the right type of water heater is key, especially with Iowa’s long, cold winters. Let’s explore the pros and cons of each type:
Tank Water Heaters (Traditional Storage Units)
How They Work: Stores a set amount of hot water (usually 40–50 gallons) and keeps it heated continuously.
Pros:
- Lower upfront cost
- Familiar to most homeowners
- Straightforward installation
- Works well for families with steady water usage
Cons:
- Can run out of hot water
- Higher energy use (especially in winter)
- Larger footprint in your home
Best for: Households on a budget or those replacing a similar tank unit with no major plumbing changes.
Tankless Water Heaters (On-Demand Systems)
How They Work: Heats water only when you need it, no storage tank required.
Pros:
- Energy efficient (no standby heat loss)
- Endless hot water
- Compact and wall-mounted
- Longer lifespan (15–20 years)
Cons:
- Higher upfront cost
- May require gas line or electrical upgrades
- Limited output if multiple hot water sources are used at once
Best for: Modern homes, eco-conscious families, or homeowners looking to save long-term on energy bills.
Hybrid (Heat Pump) Water Heaters
How They Work: Combines traditional tank storage with a heat pump to pull in ambient heat and warm the water more efficiently.
Pros:
- Very energy efficient
- Rebates often available
- Great for warm spaces like basements
Cons:
- Higher initial investment
- Less efficient in cold spaces (not ideal for garages or unheated basements)
Best for: Iowa homeowners with heated basements or utility rooms and a desire for long-term savings.
Gas vs. Electric: Which Is Better in Iowa?
Both electric and natural gas water heaters are common in West Des Moines. The best choice depends on your home’s setup and energy goals.
- Gas Water Heaters are typically cheaper to operate and heat water faster. Great for Iowa’s cold winters.
- Electric Water Heaters are easier to install and don’t require venting, making them more flexible for some homes.
