Des Moines homeowners near the Des Moines Marina ask us the same question about tankless water heaters: is it really worth it for my house? Greener Cleaner answers honestly, with real numbers on gas line capacity, venting, and installation cost before you commit.
Every tankless installation in Des Moines is completed by a licensed, bonded, and insured technician (Plumbing Lic. GREENCH741OS, HVAC Lic. GREENCH769NG). Because our team works on both plumbing and gas-fired equipment, we evaluate the whole system, including gas line size, venting path, and condensate drainage, rather than just mounting a new unit on the wall. You get a written quote that covers those upgrades before work begins.
Honest answers for Des Moines homeowners, before you spend a dollar.
Watch for the signs that a tank has reached its limit: hot water that runs out when two people shower back to back, a unit more than ten years old, rust-colored water, or a tank that has started to leak. If any of those describe your Des Moines home, it’s worth pricing tankless alongside a standard replacement. For homes near the Puget Sound shoreline, where a mix of older coastal and marina-adjacent homes is common, we often find that the water heater closet or garage space can be reclaimed once a wall-mounted unit goes in.
The biggest question with tankless is whether your home can support it. A tankless unit needs a gas line sized for a much higher burn rate than a tank, a vent path to the outside, and a water supply with enough flow to keep the burner firing. For Des Moines homes near the Puget Sound shoreline, we check each of those before recommending a model, and we size the unit to the temperature rise you actually need in winter rather than the number on the box. That prevents the classic tankless disappointment: a unit that handles one shower but struggles when the dishwasher and a second bathroom join in.
One local detail worth knowing in Des Moines: many homes near the Des Moines Marina were built with a water heater closet or garage corner sized for a 40- or 50-gallon tank, and a wall-mounted tankless unit frees that space for storage. We measure the existing space, the gas meter location, and the likely vent route during the estimate, so you can see exactly what the finished installation would look like before you decide.
Plenty of Des Moines homeowners come to us after a tankless installation elsewhere left them with weak flow or error codes. Most of those problems trace back to sizing, gas supply, or venting, which is why we check all three before recommending a unit, and why we’re comfortable servicing tankless systems we didn’t install.
We also serve nearby communities including Redmond, Renton, and Seattle. Dispatch is coordinated across these areas, so a technician already working nearby can often reach you faster than a scheduled appointment would suggest.

Plan on an annual flush to remove mineral scale from the heat exchanger, plus a periodic check of filters and venting. It's quick service that protects efficiency and your warranty.
Yes, tank-to-tankless conversions are a core service. Expect changes to venting, gas supply, and piping at the new wall location, all of which we include in the estimate.
It can be, mainly for the space savings and the absence of standby heat loss. For very low hot water use, the efficiency savings are smaller, and we'll tell you if a high-efficiency tank is the better value.
Most gas tankless units need electricity for the controls and fan, so they stop without power. A small battery backup is an option if that matters for your home.
Sizing depends on how many fixtures run at once and the temperature rise from your coldest incoming water to your target temperature. We calculate it for your home rather than guessing.
Some models are rated for outdoor mounting, which can simplify venting. In our climate, freeze protection is the main consideration, and we'll advise whether it suits your property.
A tankless unit still has to push water through the pipes from the heater to the fixture. A recirculation system can shorten that wait, and we can quote one if it bothers you.
Utility and manufacturer incentives change from year to year and vary by provider. Check your utility's current programs, and we'll provide the model and efficiency details you need for an application.
Codes usually point to venting, gas supply, flow, or scale issues. Call us with the code and model number and we can often narrow down the cause before the visit.
Yes, we repair and descale tankless units from major brands regardless of who installed them.
A straightforward replacement is often completed in a day, while conversions with new gas or venting work can take longer. We'll give you a realistic timeline in the quote.
