How long does a tankless water heater last compared to a tank?
A well-maintained tankless system typically lasts 20 years or more, roughly double the lifespan of a traditional tank water heater, which usually needs replacing every 8 to 12 years.

What to Expect from the Hive's Tankless Water Heater Service
Our colony starts by listening to your hot water concerns, whether it's a unit that won't fire, temperatures that fluctuate, or a new install for a renovation. A licensed master plumber explains the issue in plain language and walks you through your options. For repairs, our worker bees diagnose using manufacturer-specific tools to pull the real error code rather than guessing. For installations, we assess your home's gas line capacity, venting, and hot water demand to recommend the right-sized unit, not just the most expensive one. We test everything fully before we leave, clean up thoroughly, and won't consider the job done until you're 100% satisfied. That's the hive standard, every time.
The Hive5 Difference
Tankless Work Done Right, Bee-yond the Surface
A tankless installation might seem straightforward, but doing it properly means checking gas line sizing, venting, and real household flow-rate demand, not just mounting a unit on the wall. These details determine whether your system runs sweet for 20 years or leaves you with lukewarm water and short-cycling within months.
Proper Sizing, Every Time
Undersized tankless units are the number one cause of "not enough hot water" complaints. Our worker bees calculate your home's actual simultaneous demand before recommending a unit.
Manufacturer-Trained Diagnostics from Our Hive
We use brand-specific diagnostic tools for Rinnai, Navien, Rheem, and other major tankless brands, so repairs address the real problem, not just the symptom.

If you are looking for an exceptionally skilled, expert plumber, Demitri from Hive5plumbing is the absolute best. We were stressed out by an urgent leak under our basement laundry sink, while also needing our old kitchen and laundry faucets replaced. Demitri responded to our inquiry right away and got us onto his schedule for the emergency repairs. He did an absolutely excellent job with everything! He is very reliable, meticulously thorough and highly knowledgeable at what he does. We are incredibly happy with his work and will definitely use his plumbing services in the future. If you are looking for a skilled plumber who delivers flawless work with complete honesty, we highly recommend him!
Anna
We had a cracked drain pipe in my kitchen sink so we called Hive 5 plumbing & spoke to Demitri explained the problem and what had to be done.He was efficient, knowledgable, fixed the problem & cleaned up afterwards. I would definitely recommend him for any plumbing job.
John
Had a great experience with our plumber Demitri today. We had a pretty messy sewage ejector pit that needed a full clean-out, and he handled it incredibly well. He was extremely clean and careful throughout the entire process—something I really appreciated given the nature of the job. There was no mess left behind, and everything was handled in a very sanitary and respectful way. On top of that, he was professional, courteous, and easy to communicate with from start to finish. Highly recommend if you’re dealing with anything similar—especially jobs that require extra care and cleanliness. Will definitely hire again for future plumbing jobs.
Federico
2020-April my entire drain assembly under my kitchen dual sink basin was replaced. We talked on the phone and i shared some images. Demitri shared his recommendation and cost and made himself available the very next morning. During covid-19 pandemic period, I asked what precautions he would take and he wore his mask in my home. Demitri is pleasant and comfortable person to speak with. Replaced entire drain in just over an hour; readjusted the slope of my external drain, answered all my concerns, questions and fully explained his work. Demitri will definitely be in my contacts for future plumbing needs. Thank you again, Edward. 2024-April: ...late post. Last year I contacted Demitri again this time to replace a shower valve. Great job but even better was when there was a leak problem, he took responsibility and coordinated help to fix the problem. When a tradesperson does not hesitate to take responsibility for a problem even after leaving and receiving payment; and then make it "good", then this means a lot for me! Thank you Demitri
Edward
Dimitri has serviced our home on two occasions. We first had him install 3 new toilets which were completed with attention to detail. He's also very friendly and explains the work being done. Most recently we had Dimitri at our home to sort out faucet issues.
Andre
I had toilet installation that required rerouting the waterline in order for the new style toilet to fit. This was beyond what I could handle for DIY, and I am glad I called in the pros when I did. He gave me good advice for pausing the work I started to avoid a leak, and defer the service to avoid an after hours service call until Monday morning. First thing on Monday, he rerouted the water line and positioned it neatly for easy access and replaced the leaky shutoff valve. He also noticed the existing flange was not screwed in to the floor and fixed that for me too, which I would not have known was a problem. He installed the toilet, shimmed it level, and caulked it cleanly. He also installed the bidet for me so everything is ready for my family to use now. Price was fair and communication excellent. I found Hive 5 Plumbing as a referral on NextDoor app, so they were recommended by people in my community.
Joel
Quick and efficient service. I ended up needing a plumber when I decided to change my dishwasher due to old style connections. Dimitri gave me an appointment right away, showed up on time and did a great job. Would recommend 100%.
Kiarash
Hive 5 Plumbing did a fantastic job with my 4 bathrooms. Shutoff valves on sinks and toilets. He also noticed some hose plastic hold were cracking or in poor condition. The very last minute my wife wanted a new kitchen motion sensor faucet and he gladly installed it. Thank you Demitri for the updates, quote prior to work and other suggestions post service. Price was reasonable. 100% trust worthy and on time with great communication A+++++++
Saturn
I had Hive 5 Plumbing & Drains work on 2 bathrooms (install 4 lock-off values, 2 faucets, and 2 sink drains). During the installation, Demitri noticed that one of the drains was partially clogged and debris removed, which to me demonstrates a high quality of work. It was quick to schedule the service call, Demitri arrived on time, was very friendly, and left the work area very clean. I would highly recommend Hive 5 Plumbing & Drains for any plumbing work.
Perry

I am very satisfied with his work and will definitely use his services again in the future.
Nina
Easy 5 stars! I needed plumbing services, Demitri came same day within a couple hours. Very professional, knowledgeable, skilled and fairly priced!

Darren
My family have trusted them before and we’re not let down again. Clear discussion of the issue, what the solution could look like and likely causes before starting and clear understanding of costs. Then during and after the fix they show you what occurred and answer any questions etc.
Stephen
Excellent service! Dima was very professional and knowledgeable. Would highly recommend.

Frequently Asked Questions
Common questions about tankless water heater installation, repair, and maintenance across Vaughan, Woodbridge, and surrounding communities.
Why does my tankless water heater run out of hot water when two things are running at once?
This usually means the unit is undersized for your household's simultaneous demand. Running a shower and the dishwasher together may exceed the unit's flow rate, causing it to prioritize or fall short. A flow-rate assessment can confirm whether your unit is properly sized.
Do tankless water heaters need regular maintenance?
Yes. Hard water causes mineral scale to build up inside the unit over time, reducing efficiency and eventually causing failures. Most manufacturers recommend descaling annually, especially in areas with hard water.
Can I convert from a tank water heater to tankless?
In most cases, yes. Conversion may require upgrading gas line sizing or venting to meet the tankless unit's requirements. A quick assessment during your free estimate will confirm what's needed for your home.
Is a tankless water heater worth the higher upfront cost?
Tankless systems cost more upfront but use less energy since they only heat water on demand rather than maintaining a full tank around the clock. Combined with a longer lifespan, most homeowners recover the difference over time through energy savings and fewer replacements.
