Is your shower turning cold halfway through? Is your utility room smelling like rust? If your water heater is over 10 years old, it's probably trying to tell you something.
Replacing a water heater is a major household investment—one that impacts your comfort, utility bills, and daily routine for the next decade or more. With advancements in technology, there are more options than ever, ranging from high-efficiency heat pumps to endless tankless hot water systems.
At Lakeside Heating, Cooling & Plumbing, we want to help you make the best choice. Here is your ultimate guide to the different types of water heaters available and what you need to consider before buying.
Conventional Storage Tank Water Heaters
These are the most common heaters, holding 40–80 gallons of water and keeping it hot 24/7.
Best for: Homes with a strict upfront budget, traditionalists, or quick replacement scenarios.
Pros: Lower initial purchase and installation costs. Reliable performance.
Cons: Less energy-efficient (constantly heating water). Takes up significant floor space. Limited capacity; can run out of hot water.
Key Consideration: Look for high-efficiency models with longer warranties.
Tankless (On-Demand) Water Heaters
These systems heat water instantly as it flows through the unit, eliminating the need for a storage tank.
Best for: Small spaces, eco-conscious homes, and families who run out of hot water frequently.
Pros: Endless, on-demand hot water. High energy efficiency (no standby loss). Longer lifespan (often 20+ years). Compact, wall-mounted design.
Cons: Higher upfront cost. May require upgrading gas lines or electrical panels.
Key Consideration: Sized by "gallons per minute" (GPM). Our team can ensure you get a unit that handles simultaneous showers and appliances.
Heat Pump (Hybrid) Water Heaters
These are the most energy-efficient option available. They use electricity to move heat from the air into the tank rather than generating heat directly.
Best for: Energy savings-focused homeowners in moderate to warm climates.
Pros: Can cut water heating energy costs by up to 70–75%.
Cons: Highest upfront cost. Needs ample space for airflow, best suited for garages or utility rooms with adequate clearance.
Key Consideration: They also dehumidify the surrounding air, which is a bonus for humid garages.
What to Consider When Purchasing (The Checklist)
Before you buy, answer these five questions to narrow down your search:
1. What is your fuel source?
Do you have natural gas, propane, or electric? While you can switch types, it is usually cheaper to stick with your current infrastructure.
2. How big is your household?
A family of four typically needs a 50-gallon tank or a high-capacity tankless unit to avoid cold showers.
3. How much space do you have?
If your utility closet is cramped, a tankless unit is ideal. If you have a large garage, a hybrid heat pump is a great choice.
4. What is your budget?
Tank heaters are cheapest upfront, but tankless and hybrid units often offer better long-term savings through lower utility bills.
5. Is it "Smart"?
Modern units offer WiFi connectivity, letting you control temperatures from your phone and providing leak detection to prevent flooding.
