Tankless water heater FAQs
How much does a tankless water heater cost?
Tankless units cost more upfront than a traditional tank, largely because installation may involve new venting, gas or electrical work. But they use less energy and last far longer, so they often cost less over their lifetime. You'll get an upfront written quote at your free estimate, and financing is available to spread the cost.
Is a tankless water heater worth it?
For many homes, yes — endless hot water, lower energy bills, a 20+ year lifespan, and reclaimed floor space add up to real long-term value. It's an especially smart move if your current tank is failing anyway. We'll assess your home honestly and tell you whether it's the right call for you.
Do you really never run out of hot water?
Correct — a tankless unit heats water continuously as it flows, so it doesn't drain a reserve the way a tank does. The key is proper sizing: we calculate your home's peak demand so the unit keeps up even when multiple fixtures run at once.
Do tankless heaters need maintenance?
A little. Periodic descaling keeps them running efficiently, especially in hard-water areas — and if your water is hard, a water softener helps protect the unit. RoyalShield members stay ahead of this with seasonal maintenance reminders.
How long does installation take?
A straightforward tankless replacement is often done in a day. Converting from a tank can take longer if new venting or a gas-line upgrade is needed — we'll give you a clear timeline as part of your estimate.
