Tankless Water Heaters

Tankless Water Heater Installations in Alameda & Oakland

Tankless water heaters are pretty commonplace now and many of the brands are extremely reliable, so much so that Big Blue offers a full 15 year warranty on some of our models. Tankless water heaters have several advantages over traditional storage tanks: energy efficiency, running cost, endless hot water and reduced carbon emissions. Some models are completely weather proof and can be mounted directly on the exterior of the home which can free up space in an interior closet, kitchen or laundry room. Because they do not store hot water and heat water as you use it, the water hot water supply will never run out, you could literally get in the shower on Tuesday and not get out until Friday and you would still have hot water. The flip side to this, when you are not running hot water, you are not spending anything on keeping a 50 Gallon tank hot, so this is where some of the savings come in.

There are some considerations to understand about tankless hot water. The number one issue is that it can take longer for you to get hot water than you are used to and this can cause concerns about wasting water, particularly in a drought. The unit must be sized and located properly in order to give you the hot water you are expecting, it is important to avoid long pipe runs with tankless heaters to avoid having to wait a long time for your water to get hot. To avoid maintenance issues and to ensure you get the maximum life expectancy from your tankless water heater, the correct gas pipe sizing is crucial.
The oddly named “Cold Water Sandwich” occurs when water in the pipe is already hot so when you turn on the faucet or shower hot water comes out but you are starting the firing process at the heater anew. This cause a few seconds of cold water to come through the pipe before the new hot water is delivered. These “quirks” with a tankless water heater are easily overcome and I do not know of anyone who would switch from a tankless to a traditional tank.

The initial investment when installing a tankless is increased over the cost of a traditional but as the life span is longer, the running costs are lower and the warranty is so much better, if you plan on living in your home for more than 8 years, it typically is a better investment.

Permits: According to the Contractors State License Board, “It shall be considered un-lawful to install any water heating appliance without an inspection by the local authorities”. Big Blue plumbing can purchase and manage the permit process.

When I called in for service for a clogged drain I spoke to Ebony, who right off the bat was helpful and informative on what I could expect from them during their visit.

We were serviced by RJ Mattson. Who was prompt and understanding of our loud and obnoxious pit bull which is a plus because some people are afraid of loud barks…

He quickly realized our problem was not just a clogged drain but that we potentially had a much bigger problem and proceeded to explain in detail what issue we were dealing with. He even offered to explain the issue with our landlord which was very helpful. After all he is the expert, he could explain it much better than me.

The visit was relatively short being we weren’t prepared to handle the repair cost immediately.
But with the visit being short RJ was kind enough to offer to take the $67 dollars they charge for a diagnostic and put it towards the estimate total. We will be using BBP without hesitation!

We are in the process of selling our home and the city of Oakland requires a lateral sewer inspection. Long story short….we needed to replace the hook-up from the house, install required regulatory items, and replace the sewer pipe to the street.
Nick, RJ, and Cesar “teaspoon” Rivera were all very helpful in explaining the process and requirements.

All of this work included extensive digging in the front yard and street. Cesar was really helpful during the pipe replacement. He checked on the contractors to ensure the work was being done correctly and he even replanted a plant that had to be dug up. He listened to me and and showed empathy when I discovered my prize hydrangea would not be able to replanted due to the meters they had to install. He made sure everything was back in order.

There was quite a lot of dirt and debris left from the project. Crispin Orozco made sure it was cleaned up and back in the condition it was before all the work started. Crispin even replaced some of the garden mulch that had been lost in the digging process and evened out the wood chips around the plants.

Big Blue is our go-to Plumbing company. They do great work and all of the people I have met have been very professional, friendly, and knowledgeable.

I can’t say enough good things about this company. They are professional, friendly, efficient, and hard working. We have a pretty serious plumbing situation that will require more work, but on day one the team came out and worked their you-know-whats off for about 8 hours. They explained everything to us clearly and gave us multiple options on how to proceed before starting anything. I have never had such a positive experience with any plumbing company before, and I would definitely recommend Big Blue to anyone who needs a plumber. Totally top notch.

the best plumbing and heating company bar none. for nearly a month, we experienced intermittent hot water outages. we called two other plumbing companies who did nothing but waste our money. one of them, Leapfrog, after gladly charging us a handsome sum simply told us that they didn’t know what was wrong and told us to call the boiler company directly. ridiculous. Paul and Zach, unlike other companies, were professional and knowledgeable from the start. they took the time and effort to understand our house’s heating and water systems. after patiently troubleshooting everything, they found the root cause. we now have hot water and consistent heating throughout our house thanks to their work. these guys are busy and in high demand for a reason – they’re simply the best and worth every single penny. don’t waste your time with others who claim to be experts at what they do. Big Blue Plumbing are true masters of their craft. we’ll be lifetime customers and proud advocates for this great business.

Big Blue really helped us out. I reached out with a very unconventional request and they were able to fulfill it in a prompt and kindly fashion. Very compassionate despite the circumstances. I had called every plumber in town and Zack’s response really saved the day. I can’t recommend enough. Thanks so much Big Blue!

I am an architect in Berkeley and know value in the trades when I see it and experience it. Big Blue replaced our broken sewer lateral and never complained when the job was harder (pipes deeper) than they anticipated. Great at details and communication. 5 star plus

The people they send are always top notch. Nick is who you want to request if you can get him. I am a member of the Big Blue program which gives you priority service and cost discounts. You pay a few bucks a month to be in the program. With an older house like ours it is worth it. You need those discounts too because these guys tend to be a bit more pricey than other plumbers I have priced out. But as the saying goes, “cheap plumbing can get expensive”.

I found Big Blue Plumbing on a Yahoo search. From the start they were great. The office receptionist Briana was very courteous. She was knowledgeable of the different heating systems and set up an appointment for me right away.

Today Zack from Big Blue Plumbing came in to check on our unit. His arrival time was set up for between the hours of 8 – 10am. He called me prior to arriving, he got here at 8:45am., unfortunately our heat/air system is not one they service. However, Zack stayed and checked our unit, troubleshooting the problems we were having. He was able to let us know what he found he took several pictures for us (to further help us as we find someone who works with Hydronic heating systems.

Zack was very professional, explained everything clearly and left us with some help to make our search a lot easier.

Thanks Zack, you were excellent and we really appreciate your help and dedication to your work.
