1. Gas Line Sizing
Tankless units can require up to 199,000 BTUs. We check if your gas line is large enough to deliver that load without starving your furnace or stove.
Endless hot water, space-saving design, and fully code-compliant installation across the Wasatch Front. Our licensed Utah technicians evaluate your gas lines, venting, and electrical capacity before every install.
Many Utah homeowners are switching to tankless water heaters to escape the limitations of traditional storage tanks. Unlike a 50-gallon tank that constantly heats water and eventually runs cold, a tankless unit heats water on demand.
At Slate Plumbing Co., we specialize exclusively in water heater installation and replacement. Our licensed technicians are experts in tankless systems, from proper gas line sizing and venting to managing Utah's challenging hard water conditions.
Perfect for large families. Fill a soaking tub without draining the tank.
Wall-mounted units free up valuable floor space in your mechanical room.
With proper maintenance, units can last 20+ years—nearly double a traditional tank.
No standby heat loss means your utility usage is more efficient.
Modern, compact, and efficient.
Before we install, we perform a thorough assessment. A tankless unit demands significant power in short bursts, so we verify your infrastructure first.
Tankless units can require up to 199,000 BTUs. We check if your gas line is large enough to deliver that load without starving your furnace or stove.
These units need special venting directly outdoors. We assess your mechanical room to ensure a safe path for intake and exhaust air.
Even gas units need electricity for digital controls and ignition. We ensure you have the proper outlets and connections in place.
Our technicians provide on-site infrastructure audits to ensure a code-compliant installation.
When you turn on a hot water tap, cold water travels through a pipe into the unit. A gas burner heats the water instantly. You don't wait for a storage tank to fill up. However, it's important to have realistic expectations.
A tankless unit's output limits the flow rate. If you run the dishwasher, washing machine, and two showers simultaneously, you might stretch the unit. We help you size the unit correctly for your household demand.
"Endless" means the heater won't run empty. "Instant" refers to heating speed inside the unit. You will still have a brief wait for hot water to travel through your pipes to the shower, just like with a tank.
If you live along the Wasatch Front, you already know our water is very hard. High mineral content causes scale to build up rapidly on the heat exchanger. That buildup reduces efficiency, shortens service life, and can create warranty issues with some manufacturers when annual descaling and recommended water treatment are ignored.
Our proven four-step process makes upgrading to a tankless water heater straightforward. From initial evaluation through final walkthrough, we focus on safety, code compliance, and long-term performance.
We perform a comprehensive evaluation of your gas load and venting route to provide a fixed-price quote.
Once approved, we set a service time that works for your calendar.
Licensed technicians remove the old unit, modify lines, and install the new system safely.
We show you the controls, explain maintenance, and bill only when you are satisfied.
Pricing varies based on your home’s readiness. We provide accurate quotes before starting work, but these are the main cost drivers:
Converting from tank to tankless is more labor-intensive than a direct swap.
Upsizing pipes to handle higher BTU loads adds to the scope.
Longer runs to an exterior wall or roof require more materials.
Higher output units for larger homes cost more than smaller models.
Condensing units need a drain line or pump for condensate water.
Maximize your high-efficiency investment. In 2026, certified gas tankless systems with a UEF of 0.81 or higher may qualify for the federal Section 25C tax credit, covering 30% of the project cost up to $600. Utah homeowners may also qualify for Dominion Energy ThermWise rebates that often reach $350 to $450 on eligible high-efficiency models.

Yes. Tankless water heaters eliminate standby energy loss by heating water only when needed. While the upfront installation cost is higher, most Utah homeowners see meaningful savings over the 20+ year life of the unit through reduced monthly utility bills.
No. Proper tankless installation requires upgrading gas lines to handle high BTU loads, installing code-compliant venting, and precise electrical connections. Incorrect installation can cause carbon monoxide poisoning or fire hazards. Always use a licensed Utah plumber.
Endless hot water means the unit will never run out, but it does not mean instant delivery. Hot water still must travel through your home's pipes. Proper sizing and strategic placement help minimize wait times.
Because of Utah's very hard water, annual flushing (descaling) of the heat exchanger is essential. Many manufacturers also expect documented maintenance, and some recommend water treatment to help protect warranty coverage in hard-water conditions.
Yes. Tankless systems are excellent for large tubs because they heat water continuously. Properly sized units can keep up with high-demand fixtures without the tank ever running cold.
Most modern gas tankless units require electricity for the ignition and digital controls. Without power they will not operate unless you have a battery backup system or a standby generator.
