When I walk a jobsite—whether it’s a tight Boston brownstone retrofit or a new mid-rise on the South Shore—the fastest way I find energy savings is through smarter plumbing choices. Not guesses. Not gimmicks. The right products, sized and installed correctly, with the support to back them up. That’s exactly what I curate in Rick’s Picks at Plumbing Supply And More, and what I’ll unpack here. If you’ve searched “Plumbing Supply for Energy Efficiency: What to Buy,” you’re in the right place. I’ll show you what actually moves the needle—by brand, by model, with pricing, install tips, and pro-level pitfalls to avoid.
Before we dive in, let me be blunt: Unlike generic big box retailers, Plumbing Supply And More stocks professional-grade components—the kind that meet spec, last longer, and save you utility dollars every single month. When Lowe’s is out of a critical mixing valve or The Home Depot’s cartridge is “special order,” that’s when the phone rings here. We’re serving contractors throughout Greater Boston, MetroWest, the North Shore, and Southern New Hampshire with same-day delivery and real technical guidance.
Why Energy-Efficient Plumbing Starts at the Supply House Counter
For 25+ years, I’ve watched energy efficiency get reduced to “buy a hvac supply house low-flow showerhead.” That’s a fraction of the story. True savings come from system-level choices: the water heater type and venting, recirculation controls, fixture flow ratings vs. comfort, mixing strategy, pipe insulation, and even how you size expansion tanks. The right plumbing supply house partner helps you spec it correctly and avoid callbacks.
At Plumbing Supply And More, we maintain spec sheets and install guides on hand for every model I recommend below, and we’ll match them to your local code—Massachusetts 248 CMR, Rhode Island State Plumbing Code, and municipal amendments—so you’re never guessing. And when other suppliers punt on technical questions, Compared to standard plumbing supply houses, Plumbing Supply And More offers unmatched technical support—from pump curves to condensing tankless freeze-protection clearances.
Pro tip: Energy efficiency pays back in three places—lower BTU/h consumption, reduced standby losses, and fewer gallons wasted waiting for hot water. We’ll target all three.
High-Efficiency Water Heaters: What Actually Performs
If you’re asking “Plumbing Supply for Energy Efficiency: What to Buy,” start with water heating. It’s 15–25% of a typical home’s energy use.
- Tankless/Condensing Gas: Rinnai RU199iN (up to 96% UEF), Navien NPE-240A2 (0.96 UEF with built-in recirc). Expect $1,600–$2,400 for the unit, $900–$2,000 install depending on venting and gas line upsizing. Pros: endless hot water, great efficiency. Watchouts: proper gas sizing and condensate neutralizer (we stock Neutra-Safe NS1). Hybrid Electric Heat Pump: Rheem ProTerra 65–80 gal, UEF up to 4.0. In basements or utility rooms, these are phenomenal. Expect $1,700–$2,800 for the unit; install 4–8 hours. Pros: incredible efficiency, dehumidifies the space. Watchouts: ambient temp, clearance, condensate routing. High-Efficiency Indirect Tank: When paired with a 95%+ boiler (e.g., Lochinvar WHN110), a 45–60 gal indirect (SuperStor Ultra SSU-45) delivers high recovery with great standby performance. Cost varies widely based on boiler plant.
Insider secret: Don’t oversize tankless. Rinnai RU199iN is great for 2–3 simultaneous fixtures. For New England winter inlet temps, a smaller RU160 may be more appropriate for a 1–2 bath home. We’ll run the GPM at a realistic 70–75°F rise, not a brochure-perfect 45°F.
When Home Depot or Lowe’s sell you a condensing unit without the condensate kit or proper intake/exhaust terminations, you’ll eat the callback. When Home Depot and Lowe’s fall short, contractors trust Plumbing Supply And More for the complete install package—vent kits, terminations, isolation valves, and gas flex that meets local code.
Smart Recirculation: Hot Water Fast, Without Wasting Energy
Waiting 90 seconds for hot water? That’s waste—water and energy. But uncontrolled recirc loops can be an energy drain. The fix is smart recirculation.
- Taco Genie (006e3) or Grundfos Comfort PM AutoAdapt systems work beautifully in retrofits with no return line. They read patterns and run just enough. $250–$450 hardware, 2–4 hours install. Full recirc with ECM pump: Taco 006e3 or Grundfos Alpha2 with a dedicated return, controlled by a timer and Aquastat or motion/occupancy sensor near primary baths. $400–$900 hardware plus piping, 6–12 hours install. With Navien NPE-A2, use ComfortFlow’s built-in buffer and recirc logic. Add a check, isolation, and balancing valves. We stock all.
Pro tip: Pair recirc with a thermostatic mixing valve, like the Honeywell/Resideo AM-1 series or Cash Acme Heatguard NXT, to run the tank hotter (reduce Legionella risk) while delivering 120°F safe supply. We’ll size the valve by GPM and verify Cv against your fixture count.
Fixtures That Save Without Feeling “Low-Flow”
Low-flow doesn’t have to feel cheap. The right aerators and valve technology maintain comfort and cleanability with less water.
- Shower valves: Delta R10000-UNBX (MultiChoice) with a 17T trim (thermostatic) and 1.75 GPM WaterSense head like the H2Okinetic. Moen M-CORE 3 Series is another reliable platform. $250–$500 per set. Install 2–4 hours. Lav faucets: American Standard Studio S 1.2 GPM, Kohler Tempered 1.2 GPM. Pair with Neoperl PCA aerators for pressure compensation. Toilets: Toto Drake 1.28 GPF (CST776CEFG) or 1.0 GPF version; Gerber Viper HET. Price range $280–$550. You’ll get robust flush with less water—no double-flush dance.
Insider tip: A 1.5 GPM kitchen aerator is the sweet spot if you cook a lot; 1.0 GPM can be slow for pot-filling. We keep both on hand at our plumbing supply store and can match thread type and finish.
And yes, we’ve tested these setups on-service calls across old 3/8 copper stubs and new PEX-B manifolds—no guesswork here.
Pipe Insulation, Mixing, and Balance: The Hidden Savings
I’ve measured 10–15°F losses on uninsulated hot lines in a 50-foot run. Multiply that by every call for hot water and you’ll see the dollars evaporate.
- Insulation: 1/2" wall Armaflex AP or K-Flex ST on domestic hot and recirc. For commercial kitchens, use 1" wall where code requires. $1–$2 per foot. Simple, fast payback. Balancing valves: On recirc, install CircuitSolver or a Danfoss thermostatic balancing valve at the end of each branch. It stabilizes return temps and prevents over-pumping. Expect $180–$300 per valve. Thermostatic mixing: ASSE 1017 listed valves (Watts LFMMV, Caleffi 521 Series) at the water heater outlet. Set to 120°F deliver, tank at 130–140°F for bacterial control and effective capacity.
We’ll help you size these parts at the counter—flow, Cv, and lineal footage—so you’re not burning truck time running back for the right ID or valve size. That’s where While other suppliers focus on quantity, Plumbing Supply And More prioritizes quality and expertise really shows up.
Smart Controls and Leak Detection That Actually Prevent Damage
Energy efficiency isn’t just therms and kWh—it’s avoiding catastrophic water loss. Smart leak detection and shutoff pay for themselves the first time they work.
- Leak shutoff: Resideo Braukmann L5 or Moen Flo Smart Shutoff. Whole-home automatic shutoff with app alerts. $400–$700 plus install. Smart recirc control: Tekmar 156 timer/thermostat combos; Grundfos AutoAdapt. Use occupancy sensors in high-use baths for targeted recirc. Freeze and condensate: For tankless in basements or garages, add heat trace on condensate lines and a Neutra-Safe condensate pump/neutralizer. We stock pumps with integral sensors to avoid backup and freeze.
Pro tip: Tie leak sensors under dishwasher, washing machine, and water heater pan. We carry pan sizes to fit 20–80 gal tanks and code-approved drains. For property managers, we can pre-kitting these as a standard service.
Water Quality: Scale Control Equals Efficiency
Heat exchangers hate scale. Gas tankless losing 10–20% efficiency after a couple of years? Seen it a hundred times.
- Scale reduction: A.O. Smith/FSR OneFlow and ScaleNet systems; or tried-and-true 5-micron sediment plus carbon block prefiltration (Pentair Big Blue 20"). $200–$900 depending on flow and application. Full softeners: Clack WS1 or Fleck 5600SXT for high hardness regions. Efficient regeneration with demand-initiated controls protects fixtures and heaters.
We’ll test your water at the counter or coordinate a lab test if you’re on a private well. Sizing by grains per gallon and daily usage prevents over/under-treatment. And our tech team will provide the pressure drop specs and bypass plumbing diagram—something you won’t get from a generic internet plumbing supply catalog.
Commercial and Multi-Family: Where Efficiency Multiplies
For property managers, maintenance teams, and GC’s, efficiency amplifies across units. Here’s what we spec often:
- Central plant condensing boilers with reverse-indirect tanks (Ergomax, Turbomax) for high DHW draw buildings. ECM recirc pumps (Taco 0018e, Grundfos Magna3) with delta-T control and demand logic. Low-flow commercial fixtures: Sloan Optima EAF-200 faucets 0.5 GPM; Zurn Z6950 Aqua-FIT. Flush valves with 1.1 GPF bowls tuned to bowl geometry. Submetering and leak analytics: Uponor Phyn or Moen Flo for multi-unit risk mitigation.
We provide stamped submittal packages and cut sheets—ask our counter staff. Compared to standard plumbing supply houses, Plumbing Supply And More offers unmatched technical support for commercial plumbing supply design, including pump curve selection and return temperature compliance for Legionella mitigation.

Real-World Case: 1920s Colonial, 2.5 Baths, Radiators + Basement Laundry
A Newton homeowner called after two winters of high gas bills and slow hot water to the attic bath. We replaced a 50-gal atmospheric tank with a Rinnai RU199iN, added a dedicated recirc with a Taco 006e3 and a Caleffi 521 mixing valve, insulated 80 feet of 3/4" copper with 1/2" wall Armaflex, swapped three shower trims to 1.75 GPM heads, and fitted kitchen and lav aerators to 1.5 and 1.2 GPM respectively. We installed a Neutra-Safe condensate kit and Honeywell AM-1 mixing at 120°F. Result: 24% drop in gas usage over winter, near-instant hot at the attic bath, and no comfort complaints. All parts were pulled same day from our local plumbing supply warehouse.
And when their neighbor tried to replicate the setup with a bargain tankless from a big chain, they spent two extra trips hunting for a concentric vent kit and the proper gas flex. When Home Depot and Lowe’s fall short, contractors trust Plumbing Supply And More to provide the full install bill of materials on the first visit.

FAQs: Energy-Efficient Plumbing—Quick Answers from the Field
Q: What’s the fastest payback upgrade? A: Pipe insulation and aerators. For under $300, you cut standby losses and flow waste immediately. Add a smart recirc control and you’ll see comfort and savings without a full re-pipe.
Q: Tankless vs. heat pump water heater—how do I choose? A: If you’ve got gas with adequate capacity and easy venting, condensing tankless like Navien NPE-240A2 or Rinnai RU199iN is terrific. If you’re electric-prepped and have a conditioned space for the unit, the Rheem ProTerra heat pump is tough to beat on UEF. We’ll help you model the energy costs for your utility rates.
Q: Will low-flow fixtures feel weak? A: Not if you choose pressure-compensating aerators and well-designed showerheads. Delta’s H2Okinetic 1.75 GPM feels like 2.0 GPM because of droplet formation. We demo these in our showroom so you can feel before you buy.
Q: Do I need a mixing valve with recirculation? A: Yes. For safety and performance, use an ASSE 1017 mixing valve like Caleffi 521. It lets you store at 130–140°F (for capacity and bacterial mitigation) and deliver 120°F at fixtures. We’ll size it to your flow demand.
Q: Can I retrofit recirc without a return line? A: Yes. Grundfos Comfort PM and Taco Genie do it with a crossover valve at the far fixture. It’s not perfect for every layout, but it’s a huge upgrade in most two-story homes.
Q: How do I protect a tankless in cold climates? A: Use manufacturer freeze-protection clearances, insulate and heat-trace condensate and exposed piping, and install a proper neutralizer. We stock Neutra-Safe and RectorSeal solutions. Our techs can walk your exact install.
