Tankless Water Heater Maintenance

Annual tankless water heater maintenance can prevent costly repairs, preserve efficiency, and extend your unit’s life up to 20 years. A water heater flush removes sediment and minerals found in San Diego tap water.

What We Do During Maintenance:

• Descale system to remove hard water mineral buildup (especially in Julian, Alpine, Lakeside)

• Flush the water heater and clean the screens

• Check burners, flame sensors, and venting

• Test electrical components and gas connections

• Review any manufacturer firmware updates

Standard vs Tankless Water Heaters

Choosing between a traditional tank water heater and a tankless model depends on your household’s size, energy goals, and long-term budget. Tankless water heaters provide endless hot water, last nearly twice as long, and take up less space — making them a smart investment for many San Diego homes. However, standard tank systems offer lower upfront costs and may be sufficient for smaller households with predictable usage. Use the comparison chart below to see how each option stacks up and let Carini help you choose the best fit for your needs.

Gas Tankless vs Electric Tankless

Gas and electric tankless water heaters both provide on-demand hot water, but they differ in energy source, efficiency, and application. Gas tankless water heaters use natural gas or propane and typically operate at 80% to 95% efficiency, offering higher flow rates and longer service life than traditional tank systems—making them ideal for larger households with high water demand. Electric tankless water heaters, on the other hand, are even more efficient—often reaching 98% or higher—and are great for smaller homes or places without gas access. They’re environmentally friendly, cost-effective to operate, and offer a reliable long-term solution. Our plumbing experts can help you decide which type best fits your San Diego home and lifestyle.

💡 Electric tankless systems are ideal for smaller households or homes without natural gas access.
💡 Gas tankless systems are best for larger homes with higher water usage and existing gas infrastructure.

Pros and Cons of Tankless Water Heaters

Not sure if a tankless water heater is right for your San Diego home? Here’s a quick breakdown of the key benefits and considerations to help you decide. Our licensed plumbers will help you weigh the options and choose the system that’s best for your home, family, and budget.

❌ Cons:

• Higher Upfront Cost – More expensive to install than standard tank systems.

• Flow Rate Limits – May struggle if multiple appliances are used simultaneously.

• Maintenance Required – Descaling is important in areas with hard water.

• Retrofitting Needs – May require electrical or gas line upgrades.

Why Choose a Tankless Water Heating System in San Diego?

San Diego’s climate, home styles, and rising energy costs make tankless water heaters a smart, long-term investment. Unlike traditional tank systems that constantly reheat 40 to 80 gallons of water, tankless units heat water only when you need it, reducing standby energy loss and lowering your utility bills; especially important in Southern California where energy rates are high.

Tankless systems are also compact and wall-mounted, freeing up valuable space in older homes and smaller properties common in neighborhoods like North Park, La Mesa, Mission Hills, and Talmadge. Plus, their longer lifespan (15–20 years with maintenance) means fewer replacements over time.

For homeowners without access to natural gas, hybrid heat pump water heaters are another highly efficient alternative. These units draw heat from the surrounding air and are especially effective in San Diego’s warm climate. While both systems cost more upfront than standard tanks, they often qualify for local rebates and federal tax credits, making them a cost-effective, eco-friendly choice in the long run.

Whether you’re considering a gas tankless unit or an electric heat pump water heater, Carini’s plumbing experts will help you choose the best system for your San Diego home, water usage, and budget.

Signs You Need a New Water Heater

Higher Utility Bills

One of the key benefits of tankless systems is energy efficiency. If you’ve noticed an unexplained increase in your gas or electric bill, your unit may be working overtime due to internal wear and tear.

Frequent Repairs

If you’ve had multiple service calls in the past year, it might be more cost-effective to replace the system rather than keep repairing it. A new unit can save you money in the long run.

Age of the Unit (10-15+ Years)

Tankless water heaters generally last 15 to 20 years with proper maintenance. If yours is over a decade old, start planning for a replacement — especially if other issues are popping up.

Protect Your Water Heater with Water Treatment Solutions

Hard water is a common issue in San Diego neighborhoods like El Cajon, Scripps Ranch, and Escondido, and it can dramatically reduce the lifespan of your tankless water heater. Mineral buildup from calcium and magnesium can clog the heat exchanger, reduce efficiency, and cause costly repairs.

Installing a whole-home water softener or advanced water filtration system can protect your water heater and your other plumbing fixtures from scale, corrosion, and sediment. Not only will this extend the life of your unit, but it can also improve your water quality, reduce spotting on dishes and fixtures, and make showers feel better.
