Installing tankless water heater equipment is one of the most common upgrades homeowners ask us about, and it is also the one where the details matter most. We are Riley Plumbing Heating and Air Conditioning, and we have been installing and servicing both tank and tankless systems across the Carson Valley, Reno, and the Tahoe basin since 1999. A tankless unit can absolutely deliver endless hot water, a smaller utility footprint, and lower operating costs, but only when it is sized correctly and the supporting gas, venting, and water treatment work is done right. Here is what goes into the job, and how to tell whether it is the right call for your house.
Why Homeowners Consider Going Tankless
A conventional tank keeps forty or fifty gallons hot around the clock whether anyone is home or not. A tankless unit fires only when you open a hot tap, heats water as it passes through a heat exchanger and shuts down when you close the tap. That difference in standby loss is where most of the energy savings come from.
The second draw is capacity. With a properly sized system, the shower does not go cold because someone started the dishwasher, and a family can run back-to-back showers without waiting for a tank to recover. The third is longevity and space. A well-maintained tankless unit often outlasts a tank heater by a wide margin and mounting it on a wall frees up floor area in a garage or utility closet. For homeowners weighing installing tankless water heater equipment against replacing a tank in kind, those three factors usually drive the decision.
Sizing Is Where Most Installations Go Wrong
Tankless units are rated by how many gallons per minute they can raise to a target temperature, and that rating collapses as incoming water gets colder. This is the single most important local consideration in installing tankless water heater systems in Northern Nevada. Our groundwater runs genuinely cold in winter, which means the temperature rise your unit must produce in January is far greater than in July. A unit that looks generous on paper at a sixty-degree rise may struggle badly at ninety.
So, we start by counting fixtures and how you use them. A shower runs roughly two gallons per minute, a kitchen faucet about one and a half, a washing machine two or more. If you want two showers and a sink running simultaneously in February, the required capacity is a specific number, not a guess. Riley Plumbing Heating and Air Conditioning runs that calculation before recommending a model, because an undersized unit produces exactly the cold-water sandwich complaint that gives tankless a bad reputation.
What The Installation Actually Involves
Installing a tankless water heater is not a like-for-like swap, and any contractor who quotes it that way is skipping steps. Gas-fired units draw significantly more BTU on demand than a tank heater, which frequently means upsizing the gas line or the meter to supply adequate volume without starving other appliances. We size and run that gas piping as part of the job.
Venting is the second requirement. Condensing tankless units need dedicated stainless or approved PVC venting and a condensate drain, and the old atmospheric flue serving your tank is almost never reusable. There is also an electrical connection for the ignition and controls, and on electric tankless models the service demands can be substantial enough to require a panel evaluation. We also install isolation valves at the unit so future descaling can be done without cutting pipe. Every one of these steps is code-governed, and Riley Plumbing Heating and Air Conditioning pulls the permits and carries NV License #85622 C-1 and #85623 C-21B so the work is inspected properly.
Hard Water Is The Long-Term Enemy
Our regional water is hard, and scale is the leading cause of premature tankless failure. Minerals deposit on the heat exchanger, restrict flow, force the burner to work harder, and eventually trigger error codes and reduced output. Manufacturers typically require periodic descaling to keep the warranty valid.
We recommend flushing a tankless unit annually, more often on untreated well water. Many homeowners choose to pair installing tankless water heater equipment with a water softener or treatment system, which protects the heat exchanger and extends the life of every fixture and appliance in the house. Riley Plumbing Heating and Air Conditioning installs water treatment and purification systems, so we can address both in one project rather than sending you to a second contractor.
When A Tank Is Still The Better Choice
We will tell you honestly when tankless is not worth it. If your household hot water demand is modest and predictable, if the gas service cannot be economically upsized, or if the venting path would require significant structural work, a high-efficiency tank or a heat pump water heater may deliver better value. Vacation properties that sit unoccupied for stretches, or homes where the payback window is longer than the owner plans to stay, are also worth a second look before committing.
We specialize in State brand equipment across residential, commercial, conventional, tankless, solar, heat pump, and high-efficiency product lines, so our recommendation is not driven by having only one option in the truck.
