What Is Electric Tankless Water Heater Installation Suitable For?

There are a variety of scenarios where tankless water heaters help homeowners save money. Depending on the size of the home, it’s possible that multiple units might be required to handle different appliances – like washers and dryers; or if you are needing hot water at the same time in different parts of the house.

Noritz tankless water heater and Spotify logo

Are Tankless Water Heaters the Spotify of the Appliance Industry? We Examine Five Main Similarities and Benefits

Spotify logo and Noritz tankless water heaters

Spotify announced last month that it will begin offering political coverage and news to expand on its already dominant market share in the music streaming market.

Similarly, the market for tankless water heaters is expected to experience more growth in North America than all other global markets in the next six years.

As big fans of both of these products, we at Carini got to asking: just how similar are these two industry innovators?

1) Limitless Hot Water

Tank-based water heaters offer a finite amount of hot water. Just like Spotify’s endless streaming, tankless water heaters provide limitless hot water by heating only the water that flows through them from pipes they’re connected to. Say goodbye to cold showers because another family member used all the hot water!

2) Tankless Water Heater Installation Increases Efficiency and Reduces Costs

In a traditional tank-based water heater, the tank heats water all the time. With a tankless unit, the water is only heated when you need it, which means you save money and energy. We love being as efficient and cost effective with our water usage as we are in our music streaming and discovery!

3) Twice the Life Expectancy of Storage Water Heaters

Most tankless units last about 20 years, which is double the life expectancy for tank-based units. Tankless water heaters are already the norm in Europe and Japan – only time will tell if they make traditional heaters obsolete in the US like Spotify has done to CD sales.

4) Tankless Design Saves You Space

Traditional water heaters’ large storage tanks make them inconvenient and cumbersome to place in your home. Because tankless units don’t have tanks, they’re much smaller. They’ll save you space just like Spotify’s cloud saves you space on your hard drive!

5) Recirculation Pumps Give Instant Hot Water

We love how Spotify Discover adapts to our music taste. With new technologies like smart recirculation systems, now our water heaters can learn our preferences, too!

These systems learn your peak water usage times and begin heating the water just before you need to use it. This way, there’s no wait time for hot water.

The top manufacturers of tankless water heaters include Navien, Noritz, Rinnai and Rheem.

mini splits heating in san diego

Not Just for Air Conditioning: 4 Hi-Tech Ways Mini-Splits Keep You Warm, Too 

Ask the average San Diego homeowner or business owner about ductless mini splits, and most
will tell you they believe mini splits are for air conditioning only. We’re here to correct this
common misconception by summarizing some of the features and benefits of mini split
technology as it relates to providing energy efficient heating in particular!

Heat Pump Technology Makes For All-In-One Solution

Mitsubishi mini split systems employ heat pump technology, which allow the same compressor
to provide heat and air conditioning. Because one compressor provides both heating and air
conditioning, you won’t need a separate furnace to couple with your air conditioning system.

Consistent Performance With Hyper Heating Technology

Our complete line of Mitsubishi ductless mini splits feature an innovative and exclusive
technology called “​Hyper Heating​.” ​An enhanced compressor system reliably keeps you
comfortable, even at super-frosty outside temperatures down to sub-zero levels of -13° F. Since San Diego’s perfect climate rarely approaches freezing, you’ll never have a problem heating even your coldest rooms quickly and efficiently.

Immediate Warmth With Hot-Start Technology

An integral component in all Mitsubishi mini split models, Hot-Start Technology quickly delivers
warmth when turned on. This reduces drafts and enables you to enjoy the heated
air right away.

Intelligent 3D i-see Sensor™

Some models of the Mitsubishi mini split line use advanced features like the ​3D i-see Sensor™​ to monitor the number of people in rooms and adjust the temperature automatically. These units can even sense when a room is empty and automatically switch to energy saving mode without being controlled by a user.


So don’t just consider ductless mini splits for air conditioning! They provide the same, on
demand, energy efficient heat wherever you need it most – without having to heat every room
at once like traditional heating and air conditioning systems.

drain cleaning service San Diego

Don’t Do It Yourself, San Diego! 5 Mess-Ups That Show Why You Need a Drain Cleaning Service

Many residents of America’s finest city think they can save money on drain cleaning by renting a snake or using drain cleaner instead of consulting a San Diego drain cleaning service. However, using an experienced drain cleaning company means you’ll get vital expertise to evaluate many factors and make sure your repair is properly executed.

The age, material, and length of your pipes, as well as clog type and possibility of sewer inspection camera, are all intricately interrelated and therefore best interpreted by an expert. So-called quick fix solutions like Drano and other drain cleaners are less effective and acidic and harmful to the environment.

Avoid These Scenarios By Calling a San Diego Drain Cleaning Company!

1) Sewer Snake in the Pipes

Our plumbing manager Ron helped a client who had rented a sewer snake from home depot to unclog their drain. Due to improper use, 100 feet of cable became stuck underneath asphalt. “Two days of downtime were necessary to dig up the ground, remove the cable and put the pipes back together,” says Ron. Total repair cost $9000.

2) Blown Pipe from Botched Clogged Drain Remedy

Another former client of Ron’s rented a jetting machine and used it on extremely old pipes in an attempt to remedy a persistent clog. “The client blew up a sewer line underneath concrete,” he said. “They didn’t know for two months that it was broken until water began seeping up from it.” Total repair cost: $8000

3) Wrong Sewer Snake

Choosing the wrong snake for a job can also lead to costly repairs. “I helped a gentlemen who had used too powerful of a snake and destroyed the drain fittings under his home,” said Ron. “We had to replace numerous damaged fittings and it was a real headache for everyone.” Total repair cost: $2000

4) Clogged Toilet Catastrophe!

Even using the right size snake can be an issue if it’s not right for particular fixture. “I can still remember the disappointment on this homeowner’s face when she saw that her husband had turned the inside of their toilet black by pushing a sewer snake down it. The porcelain was severely damaged and they had to purchase a new toilet.” Total replacement cost: $700

5) Possible Danger

“An electric drain snake can also be super dangerous if it catches your arm, hand or clothing,” he said. “The last thing I would want is a customer to hurt themselves doing something that would be quick and affordable to contact a drain cleaning company for.”
