What is the best water heater to buy for a home in Taunton, MA?

The best water heater depends on household size and hot water demand, since a tankless unit fits homes with steady high demand and limited space, while a traditional tank works well for lower budgets and simpler installation. Tankless units can last 20 years versus 10 to 15 for tank models. Cotti Johnson HVAC helps homeowners in Taunton, MA choose the right fit.

How much does it cost to install a tankless water heater?

Installing a tankless water heater typically costs $1,500 to $3,500 for the unit and labor, though homes converting from a tank system may pay more if gas line upsizing or venting changes are needed. Electric models cost less upfront but need adequate amperage. Cotti Johnson HVAC provides upfront tankless water heater pricing for homes in Taunton, Massachusetts and Bristol County.

How long does tankless water heater installation take?

A straightforward tankless water heater swap usually takes about half a day, while switching from a tank system to tankless can take a full day if new gas piping, venting, or an electrical upgrade is required. Cotti Johnson HVAC schedules tankless installations around each home's specific setup for customers throughout Taunton and Plymouth County, Massachusetts.

Is there an IRS tax credit for a tankless water heater?

The federal government has offered energy efficiency tax credits for qualifying high-efficiency tankless water heaters in past tax years, though the exact credit amount and eligibility rules change, so homeowners should verify current IRS guidelines before purchasing. Cotti Johnson HVAC installs ENERGY STAR-rated tankless units for customers throughout Norfolk County, MA that may qualify.

Can I install a tankless water heater myself?

Installing a tankless water heater yourself is not recommended because it involves gas or electrical connections, proper venting, and code compliance that requires a licensed professional to get right. A mistake can create a carbon monoxide or fire risk. Cotti Johnson HVAC installs tankless water heaters correctly the first time for homeowners in Taunton, Massachusetts.

How long does a tankless water heater typically last?

A well-maintained tankless water heater typically lasts 20 years, roughly double the 10 to 12 year lifespan of a standard tank water heater, largely because it only heats water on demand instead of constantly reheating a stored tank. Annual descaling helps it reach that lifespan. Cotti Johnson HVAC services tankless water heaters for homes across Norfolk County, Massachusetts.

What should I do if my tankless water heater stops producing hot water?

If a tankless water heater stops producing hot water, first check that the gas or power supply is on and the unit is not showing an error code, since many models display a fault light for airflow or ignition problems. Mineral buildup is a common cause in hard water areas. Cotti Johnson HVAC troubleshoots tankless water heater failures for homeowners in Taunton, Massachusetts.

Do tankless water heaters need regular maintenance?

Tankless water heaters need a descaling flush about once a year to clear mineral buildup from the heat exchanger, especially in areas with hard water, since skipped maintenance can reduce efficiency and shorten the unit's lifespan. The filter screen should also be checked. Cotti Johnson HVAC performs annual tankless water heater maintenance for homes in Taunton and Bristol County, Massachusetts.

Benefits of Tankless Water Heaters

Why choose a tankless water heater? These units offer several benefits, including:

Hot water on demand: Unlike traditional tank heaters that store hot water, tankless water heaters provide hot water as needed, so you’ll never run out.
Space-saving design: Tankless units are much smaller than traditional tank water heaters and can be installed in tight spaces like closets or cabinets.
Longer lifespan: Tankless water heaters typically last longer than traditional models because they don’t suffer from sediment buildup.
Lower energy bills: Tankless water heaters are more energy-efficient, as they only use energy when hot water is needed.

How Do Tankless Water Heaters Work?

Tankless water heaters use a heat exchanger to warm the water as it passes through. When a hot water tap is opened, cold water travels through a pipe into the unit, where a gas or electric element heats it to the desired temperature. The unit heats only the volume of water needed, rather than keeping a large tank of hot water ready.

Benefits of an On-Demand Water Heater Installation in Greater Taunton–Raynham, MA

An on-demand water heater, also known as a tankless water heater, heats water only when needed—there’s no storage tank keeping water hot 24/7. When you turn on a hot water tap, the unit instantly heats the water as it flows through, giving you a continuous supply.

Endless Hot Water: Ideal for families or those with high water usage.
Energy Efficient: Heats water only when needed, reducing energy consumption and associated costs.
Long-Lasting: Can last 15–20 years with proper care.
Space Saving: Compact and wall-mounted design.
Cleaner Water: A no-tank system means a lower chance of rust or sediment buildup.

Navien & Rinnai Tankless Maintenance Schedule in Silver City (Taunton) & South Shore

While tankless water heaters are lower maintenance than their tank-style brothers, they’re not maintenance-free. Both Navien and Rinnai are leading brands in tankless water heater technology, and to keep these systems running at peak performance, regular maintenance is needed. If you own a Navien unit, be sure to schedule professional Navien service to ensure proper cleaning, descaling, and system checks for long-lasting efficiency. Here’s what to do:

Every 12 Months:

Descale and flush the system
Clean the inlet water filter
Inspect the venting system
Check for error codes

Every 2-3 Years:

Inspect the burner and ignition system
Check the heat exchanger for scale and corrosion

While handy homeowners can do basic flushing and filter cleaning, it’s recommended to have a professional plumber perform a full inspection once a year to maintain the warranty and ensure safe operation. This is especially important for Rinnai systems—scheduling expert Rinnai repair and maintenance ensures your unit runs efficiently and avoids costly breakdowns.

Repair vs. Replacement for Old Tankless Units in Bristol and Plymouth Counties

Tankless water heaters are reliable, and many systems run for 20 years or more. However, once they develop issues, it may be difficult to decide between repairing and replacing them. Here’s our take:

If your tankless water heater is under 10 years old and the issue is minor—such as a clogged filter, a dirty sensor, or an ignition problem—repair is usually the best choice. However, if the unit is over 12–15 years old, needs frequent repairs, or has a failing heat exchanger, replacement is often more cost-effective. Upgrading can also improve energy efficiency and hot water capacity.

As a general rule, if the repair costs more than half the price of a new unit, it’s time to consider replacement. A professional technician can help determine the best option based on your system’s age and condition.
