Why Rhode Island homeowners go tankless
A tank water heater keeps 40 to 80 gallons hot around the clock, whether you're home or not, and when it's empty, you're taking a cold shower until it recovers. A tankless unit heats water only as it flows, on demand, so it never runs out and never burns fuel keeping a tank warm for nobody. In older Rhode Island homes where the water heater is eating a corner of a tight basement, going tankless can hand that space back too.
- Endless hot water: back-to-back showers, laundry and the dishwasher without a cold surprise
- 20+ year lifespan: roughly double a tank's, with serviceable parts instead of a rusting shell
- Lower energy bills: no standby loss from reheating a tank all day; often 20-30% less fuel for hot water
- Space savings: a wall-hung unit the size of a carry-on frees the floor a tank occupied
- Home value: an efficient, modern system buyers notice and appraisers credit
Tankless services we provide
- Installation: new tankless systems sized to your household's real peak demand
- Replacement: swapping a failing or undersized tankless unit
- Repair: ignition faults, error codes, flow and temperature problems, no hot water
- Maintenance: annual descaling and flushing, critical in Rhode Island's harder water
- Tank-to-tankless conversion: the full changeover, including gas and venting upgrades
The brands we install
We're a certified Navien installer. Their NPE tankless line is one of the most reliable, high-efficiency systems on the market, and factory certification means we install to spec and honor the long warranty. We service all major tankless brands, so if another company installed yours, we can still maintain and repair it.
Gas vs. electric tankless: which fits your home
| Gas tankless | Electric tankless | |
|---|---|---|
| Best for | Whole-home hot water, higher demand | Point-of-use, additions, smaller homes |
| Flow rate | High (5-10+ GPM) | Lower (2-5 GPM) |
| Upfront cost | Higher (gas sizing + venting) | Lower to install |
| Operating cost in RI | Lower where gas is available | Higher, RI electric rates run high |
| Venting | Required (sealed / direct-vent) | None |
| Electrical / gas needs | Adequate gas line + meter | Dedicated 240V circuits, panel capacity |
| Typical RI choice | Most common for whole-home | Cottages, additions, boosters |
Most Rhode Island whole-home conversions land on a gas unit for the flow rate and running cost; electric shines for a single bathroom, an addition or a seasonal cottage. We'll size it from your actual fixtures and tell you honestly which makes sense.
How a tankless install works
- 1. Assessment & sizing: we measure your peak hot-water demand and check gas, venting and electrical, then quote a flat price
- 2. Remove the old unit: the tank comes out and is hauled away
- 3. Upgrade the connections: gas line sizing, sealed venting, water and (for electric) the dedicated circuits, all to code
- 4. Mount & commission: the wall-hung unit goes in, we start it up, verify temperature and flow, and walk you through it
- 5. Permit & inspection: pulled and passed, with clean paperwork for your records
Financing available
A tankless conversion is an investment that pays back in lower bills and 20+ years of service. If you'd rather spread the cost, we offer financing through Wisetack, 0% terms up to 24 months for those who qualify, plus standard plans with interest. Checking your options takes a minute and doesn't affect your credit score.

Good questions
Asked before every tankless water heaters job.
How much does it cost to install a tankless water heater in Rhode Island?
It depends on whether you go gas or electric and what your home already has for gas sizing, venting and electrical. We diagnose on site and give you a flat, upfront price before any work starts, and financing is available through Wisetack, including 0% terms up to 24 months for those who qualify.
Is a tankless water heater worth it in Rhode Island?
For most households that value endless hot water and lower bills, yes. A tankless unit lasts 20+ years, roughly double a tank, and cuts the standby energy a tank wastes keeping water hot all day. In our harder water we recommend annual descaling to protect that lifespan.
How long do tankless water heaters last?
Typically 20 years or more with annual maintenance, versus 8-12 for a standard tank. Because the parts are serviceable, a tankless unit is usually repaired rather than replaced when something fails.
Can you convert my tank water heater to tankless?
Yes, tank-to-tankless conversion is a core service. We remove the old tank, upgrade the gas line and venting (or add the dedicated electrical for an electric unit), mount the new system, and handle the permit and inspection.
Do you service and repair Navien tankless units?
We do. We're a certified Navien installer, and we also repair and maintain other major tankless brands, including units another company installed.
