Sizing for Nevada winters
Tankless capacity depends on how much the water temperature has to rise. Incoming groundwater in Reno can drop into the 40s °F in winter, so a unit that seems large enough on paper can fall short in January. We size for your coldest month and peak simultaneous use.
What a conversion involves
Most tank-to-tankless conversions require a larger gas line, new stainless or PVC venting, a dedicated electrical outlet and isolation valves for future descaling. We include all of it in one price so there are no surprises.

Tankless Water Heaters FAQs
Is a tankless water heater worth it in Northern Nevada?
For most households planning to stay five years or longer, yes. Energy savings, longer lifespan and endless hot water typically offset the higher upfront cost.
Does hard water damage tankless water heaters?
Hard water causes scale in the heat exchanger if it is never flushed. Annual descaling through the isolation valves we install keeps a tankless unit running efficiently.
Can a tankless water heater run two showers at once?
A properly sized whole-home unit (typically 180,000–199,000 BTU) can run two showers and a faucet simultaneously in most Reno homes.
Are there tax credits for tankless water heaters?
Qualifying high-efficiency models may be eligible for federal energy tax credits. Ask us which models qualify and consult your tax professional.
