If you’ve ever had the hot water turn cold halfway through a shower, you know how annoying it is. That’s usually when people start wondering if a tankless system might be the answer. Both tank and tankless water heaters get the job done, but they work very differently. The best choice for your Sacramento home depends on how you use hot water, your space, and what you want out of your plumbing long-term.
At Gilmore Heating, Air & Plumbing, we help homeowners all over Sacramento, Antelope, and Rocklin figure this out every week. Let’s break it down in plain language.
How Tankless and Traditional Systems Differ
A traditional water heater uses a storage tank. It keeps 40 to 80 gallons of water hot all day, whether you’re using it or not. That means hot water is ready when you turn the tap, but it also means energy is spent reheating water that sits in the tank.
A tankless water heater heats water only when you need it. When you open a faucet, cold water runs through the unit, passes over a heat exchanger, and comes out hot in a few seconds. No big tank, no standing supply, and no constant reheating.
So: tank models store hot water. Tankless systems make it on the spot. That single difference changes how each one performs.
Pros and Cons of Each Option
Traditional Water Heaters
You’ve probably got one now. They’re simple and dependable.
Pros:
- Lower upfront cost.
- Works for households that use a lot of water at once.
- Easy to install and maintain.
Cons:
- Only so much hot water before you have to wait for it to reheat.
- Uses energy 24/7 to keep the tank warm.
- Takes up space in the garage or closet.
- Usually lasts around 10 to 15 years.
They’re tried and true, but they’re not built for maximum efficiency.
Tankless Water Heaters
Tankless systems are newer technology and built for convenience.
Pros:
- Endless hot water.
- Compact, wall-mounted design saves space.
- Uses energy only when you need hot water.
- Can last 20 years or more.
Cons:
- Higher installation cost since venting or gas lines may need upgrades.
- Can struggle if multiple showers or appliances run at once (unless sized correctly).
According to Energy.gov, tankless units can be up to 30 percent more efficient than standard tanks. For homes with moderate water use, that difference adds up.
Which Water Heater Fits Sacramento Homes Best
Homes around Sacramento aren’t one-size-fits-all. Older ranch homes might have limited space, while newer builds in Rocklin are already set up for high-efficiency systems. The right choice depends on a few key things.
Space:
If space is tight, go tankless. It hangs on the wall and frees up the floor.
Hot water habits:
If your family runs laundry, showers, and the dishwasher all at once, a tank model may still be the safer bet. Smaller households or staggered schedules usually do great with tankless systems.
Energy savings:
If you’re watching energy use, tankless is better. It heats only what you use instead of keeping a big tank hot all day.
Longevity:
Tankless systems last longer. If you plan to stay in your home for years, that lifespan helps offset the higher install cost.
Water quality:
Sacramento’s hard water can wear on both systems. Routine flushing or adding a softener protects either type and keeps efficiency up.
Installation Considerations
Swapping systems isn’t always simple. A tankless upgrade may need venting changes or gas and electrical upgrades to handle the load. That’s normal and part of why a pro should handle the job.
A traditional-to-traditional replacement, on the other hand, is usually quick. We can often install it in one visit using your existing setup.
At Gilmore, we start with a site check. We look at your current plumbing, your hot water habits, and your household size. Then we talk through options so you understand exactly what will work best. No pressure, just honest advice.
Professional Installation with Gilmore
However you decide, the installation makes all the difference. A water heater that’s too small or hooked up wrong won’t deliver the comfort or efficiency you expect.
Our licensed plumbers install both tank and tankless systems all over Sacramento, Antelope, and Rocklin. We remove the old unit, make sure your lines and vents are safe, and test everything before we leave. We also help you maintain it, flushing sediment, checking valves, and keeping the system running efficiently year after year.
We’ve worked in this region long enough to know what works. Sacramento water is hard, the climate swings, and homes here need systems that can handle both.
Ask Gilmore About Upgrading to a Tankless Water Heater Before Winter
If your current system takes too long to heat or runs out of hot water too quickly, it might be time to upgrade. Sacramento winters aren’t freezing, but they’re cool enough that you notice when the water’s not hot. A tankless system can fix that and save energy at the same time.
Gilmore Heating, Air & Plumbing can inspect your setup, explain your options, and handle the installation start to finish. We’ll help you choose a water heater that fits your home and your lifestyle.
