Tankless Water Heaters in Salt Lake City, UT
Upgrade your comfort with a tankless water heater installed by SameDay Heating & Air that delivers hot water exactly when you need it without waiting or running out. With improved efficiency and a space-saving design, a tankless water heater is a smart, modern solution for homeowners ready to get more from their hot water system.
Planning and Estimating a Tankless Water Heater
At SameDay Heating & Air, Plumbing and Electrical, we begin every tankless installation with a thorough evaluation to ensure your system is properly sized and ready to perform in Salt Lake City conditions. We account for local factors and verify that your home’s infrastructure can fully support the upgrade. Here are some steps:
- Calculate household hot water demand
- Factor in temperature adjustments from climate and elevation
- Inspect gas lines
- Review ventilation layout and performance
- Evaluate electrical panel and circuit requirements
- Note any upgrades needed to infrastructure
Benefits of a Tankless Water Heater
Endless Hot Water
Need to run appliances and get the whole family showered in a row? No problem! Tankless water heaters provide hot water on demand.
Long-Term ROI
Increased energy efficiency and fewer system replacements means that over time a tankless unit can become the cost effective solution.
Longer System Lifespan
Tankless water heaters typically last nearly twice as long as tank water heaters. We carry brands known for their quality and longevity.
Better Energy Efficiency
Not only can your utility bills be lower than a traditional tank model, but tankless water heaters may qualify for energy rebates!
Reduced Water Damage Risk
Because there is not a large storage tank full of water that can rupture, risk of major water damage is significantly lower.
Space Savings
Water heater tanks can take up a fairly large footprint. A tankless water heater is compact and wall mounted, freeing up space on your floor and within the room.
Removal and System Upgrades
Next, the existing tank water heater is drained and removed to make way for the new system. At this stage, our technicians complete any required upgrades, such as increasing gas line capacity, running new electrical circuits, or installing updated venting for safe exhaust. This phase is often the most labor-intensive, as it ensures the home infrastructure can properly support the tankless unit long term. SameDay has a team of HVAC, Plumbing, and Electrical experts and our team is able to perform updates for both gas and electrical tankless water heaters.
Installation and Testing
Technicians will then install the tankless water heater. Most are wall mounted, and we install in a way for any future accessibility needs and ensure the unit is securly anchored. Then, our certified technicians connect the hot and cold water lines, typically with isolation valves (which is beneficial for future maintenance such as descaling). After everything is connected, we test out your tankless water heater and make sure things are aligned and that hot water is flowing. Prior to job completion we check:
- Water pressure flow rates
- Temperature consistency
- Gas pressure or electrical load
- Venting and exhaust functionality

Frequently Asked Tankless Water Heater Questions
Get answers to common questions about our services and coverage area
Why do tankless water heaters last longer than a tanked one?
Tankless water heaters typically last longer because they don’t store water continuously like traditional tanks do. In a tank system, water sits inside the unit for years, which leads to internal corrosion, sediment buildup, and eventual deterioration of the tank itself. Tankless systems, on the other hand, only heat water as it flows through the unit, reducing prolonged exposure to moisture and stress on components. They’re also built with more durable parts, such as heat exchangers that can often be serviced or replaced instead of requiring a full system replacement. With proper maintenance, this design allows tankless units to operate efficiently for many more years than traditional tank water heaters.
Why are tankless water heaters so much more expensive upfront than a tank water heater?
Tankless water heaters are more expensive upfront because they involve both more advanced equipment and a more involved installation process. The units themselves use high-performance heat exchangers and sophisticated controls to heat water on demand, which increases their cost compared to traditional tanks. Beyond the equipment, installation often requires upgrades to gas lines, electrical systems, or venting to handle the higher output and meet safety standards, which adds to labor and material costs. Additionally, the installation typically takes longer and requires more specialized expertise. While the upfront investment is higher, many homeowners find that the improved efficiency, longer lifespan, and reduced operating costs help offset that expense over time.
How do I know if my home is ready for a tankless water heater?
Our technicians would need to inspect your home gas and electrical systems to appropriately and accurately answer that question. Because we look at these items as well as venting and interior space, we recommend an appointment with our team.
Do I need a water softener to get a tankless water heater?
Because of the hardness level of Salt Lake City water, it is strongly recommended to have or install a water softener. Tankless systems use a high-efficiency heat exchanger that’s more sensitive to mineral buildup. This means water heater flushes would need to be done more frequently if you opt to install a tankless water heater without a water softener. Adding a water softener helps protect the system and improve long-term performance.
How much does a tankless water heater cost?
Tankless water heater costs are dependent on the scope of the entire project, not just the cost of the unit. Our team would need to evaluate your existing setup and systems to give an accurate project quote. We offer a "good, better, best" approach to pricing which gives you some flexibility depending on your comfort needs and budget. We also offer financing and can assist with rebates. When you call to schedule an appointment, ask about any active discounts and our team will let you know if there are any applicable tankless water heater discounts.
