Tankless Water Heater Installation in Sun City, AZ
Tank-to-Tankless Conversions | Options You Can Decline | Google 5.0 Rated
Somebody has left a tankless quote on a Sun City kitchen table with more lines on it than a two-bedroom house looks like it needs. Some of those lines are real options, and some address problems a larger household has, and telling the two apart is easier here than anywhere else because the houses are a known size.
A one- or two-bathroom home has a modest busiest moment, and most of what lengthens a tankless quote is there to serve a busier one. Saying which lines those are is the first thing that happens on the call, before anyone measures anything.

Here is the hinge. Census estimates for Sun City (2020 to 2024) count about 26,600 homes, and roughly two in three have two bedrooms; add the one-bedroom homes and about three in four have two bedrooms or fewer. A house of that size has a small, well-defined set of fixtures, and a small, well-defined busiest moment. That makes it unusually easy to say what a quote does not need to contain.
Many tankless jobs start as conversions from a tank. Once the tank is emptied and removed, a wall-hung unit takes its place or is moved to a better wall, and the gas supply, venting, and, for a condensing model, the condensate drain are fitted to it. Every major make is serviced, whichever one is already on the wall.
Maricopa County's code exempts a licensed, like-for-like swap of a storage tank from a permit, but says the exemption does not apply to on-demand heaters of any size, so a tankless install here is permit work.
In homes built before 1978, we only take on work that leaves painted surfaces undisturbed. If a vent or gas route would need a painted wall opened, that part goes to a lead-safe certified contractor you hire directly; we do not perform or arrange it.
Small-House Tankless Calls
“I have to open the bathroom tap nearly all the way before any hot water shows up.”
Below the flow, the unit needs to start.
With a low-flow faucet opened partway, and cold water mixed in at the handle, the hot side can carry less water than the unit's starting point, and the burner stays off. Navien lists a near-zero minimum-flow option on some models; that, or a unit specified for it, settles a tap that leaves the burner asleep.
“The company that quoted us picked its largest model. Is bigger the safe choice in a house this size?”
In a small house it can be the wrong end of the problem, because a bigger burner also has a higher floor to clear.
A unit is meant to cover the fixtures that run at once. In a two-bath home, that is often a shower and a sink, and the flow those two draw is simple to add up from their ratings. A larger unit than that peak brings more gas demand and more heating than the house will need.
“When I shut the shower off for a moment and turn it back on, a slug of cold water comes through.”
The gap while the burner restarts.
Water sitting in the pipe cools while the unit is off, and the burner needs a moment to relight. Some models carry a small built-in buffer tank for exactly this. Navien describes its NPE-A2 condensing series as including one, along with a recirculation pump.
Sizing by the Taps, Then Hanging the Unit
How many of these run at the same time?
Showers, sinks, the washing machine, the dishwasher. Most households in a house this size name one or two, and that answer forms the basis of the rest of the quote.
Add up the peak, once
The rated flows of the fixtures that actually overlap are added together. It is a short sum in a house of this size, and it is the sum that decides which items belong on the quote.
Check the smallest draw
The least a tap in the house is likely to draw, usually a hand rinse at a bathroom sink with the handle partway open, is compared with each candidate unit's minimum flow.
Strike what the peak does not justify
A model that covers that peak and still lights at the low end is chosen, and any option the peak does not call for comes off the page with a reason said out loud. The gas line, vent, and condensate route are planned to the wall the unit will hang on.
Mount, connect and test
With the tank gone, the unit is hung and connected, and the new gas piping is leak-tested before the first hot water run.
A trickle test before we leave
The least-used faucet in the house is opened just a little, the way it would be for a quick rinse, to confirm the unit fires, and if the unit has service valves, you are shown where they are.

Keeping a Sun City Quote Short
Four Things a Sun City Quote Can Usually Do Without
None of these are bad products. Each solves a real problem faced by larger households. On a two-bedroom, one- or two-bath home, they are worth looking at hard before they go on the page, because a quote is easier to read when everything on it is doing something.
A model sized for a household you do not have
The EPA sets a standard showerhead at 2.5 gallons per minute, a WaterSense head at no more than 2.0, and a WaterSense bathroom faucet at 1.5, compared to a standard 2.2. In a two-bath home, the realistic peak is one shower and one sink, which lands between roughly 3.5 and 4.7 gallons a minute depending on what is on the wall. A model chosen for a five-fixture peak is answering somebody else's question.
A recirculation loop on a short run
Recirculation earns its place when a tap sits a long way from the heater and the wait is real. In a single-story home of this size, the heater and the bathrooms are rarely far apart, and the pump, its return line and its controls are three items on the page. It is worth timing the wait at the far tap before the loop is agreed.
A second unit, or a unit cascaded with another
Cascading applies to houses and small commercial buildings whose peak exceeds what a single unit can cover. It has no business on a two-bedroom home, and it is worth saying so plainly, because it appears on quotes where a peak was assumed instead of counted.
A softener specified past the household
Treatment ahead of a tankless heater is often sensible. What is not is a unit sized for a family of five in a house of one or two people, because a softener regenerating on a schedule made for a bigger household is doing work nobody asked for. The setting and the size both follow the house.
What is worth keeping on the page
The service valve set, because every later descale runs through it. The gas run to the wall the unit will hang on, itemized separately. And the model's minimum firing flow written next to its rated flow, because in a house with water-saving fittings the low end is the number that decides whether a half-open tap wakes the burner.
Tankless Sizing, Asked and Answered

They can at a trickle, most often when a sink is left at its lowest setting for a slow rinse. Opening the handle further toward hot is the first thing to try, and the model's minimum firing flow is the number to check if it keeps happening.
Yes, once gas reaches the spot. That means a new line from the meter or from existing gas piping, sized for the unit. Our Sun City gas page covers the buried line between the meter and the house.
A flow sensor tells the burner when water is moving. Below the maker's minimum, the sensor reads the tap as closed, so the unit stays off to avoid firing on water that is barely moving.
On one shower and one bathroom sink, a cascade is out, and a recirculation loop is usually out, because the run to the tap is short. The service valves stay, and so does the gas run to the wall. That is most of a short quote.
Yes. Its model number gives its rated and minimum flows from the maker's table, and those two numbers are compared against the fixtures in the house before anything is swapped.
