What is a tankless water heater?

Tankless water heaters, also known as demand-type water heaters, provide hot water only as it is needed. They heat water directly without the use of a storage tank.

What are the advantages of tankless over tank-type models?

Tankless water heaters help to avoid the standby heat losses associated with storage water heaters. They operate only when there is a demand for hot water. This reduces energy costs by as much as 35% a year. Tankless water heaters never run out of the water and it’s available in seconds. They require significantly less space and the majority of parts are replaceable and recyclable.

How do tankless water heaters work?

Tankless water heaters heat water without the use of a storage tank. An electric element or gas burner warms the water as it travels through a pipe. They can provide a continuous supply of hot water.

How long does a tankless water heater last?

Most tankless water heaters have a life expectancy of more than 20 years. They also have easily replaceable parts that can extend their life. In contrast, storage tank water heaters last around 10 years.

Tankless Water Heaters FAQs

Customer Reviews

When it comes to servicing and repairing heating systems, they are the greatest technicians I've ever worked with. My parents had scheduled a boiler inspection. Only them, I guess, can fix things. The whole process from ordering to installing my new heating system was excellent. Thanks!

About 10 days ago we had to turn to The HVAC Service because of our heater. Jason, the technician, finished everything fast, and he said the machine is going to perform well from here on out. Instead of saying "no, sorry, I have to go," he complied with our request for a water heater inspection. Each and every detail was examined carefully. Thankfully, there was no need for any repairs. The whole thing has beyond our expectations, and we would recommend them.

To put it simply, they have talent. They are kind over the phone and provide a courtesy call 30 minutes before the technician is due to arrive. Chris stayed with us after he repaired our overheated furnace to ensure we understood how to maintain it properly and that his work would endure. Each and every one of the possible stars should be given to this service. Their tune-ups are excellent.

It was a catastrophe to move after checking the heating systems. The previous owners were concerned about possible boiler leaks and wanted to get them fixed quickly. With the assistance of The HVAC Service, we were able to. Dave showed on the same day for his scheduled visit. Dave was a pro at working with rusty pipes. Nothing; I'm hopeless when it comes to heating system repairs, and I've learned nothing from online tutorials. This company was referred to me when my tankless water heater started leaking. Their expert diagnosed the mineral deposit and fixed the problem effectively.

Wow, that's very great! They were devoted to selling a good furnace, not the most expensive one, when I called them to buy one. My relief upon learning that competent installation was included into the price was palpable. After arriving at our place, he had everything up and running in within 90 minutes. Thanx.

Professionals from The HVAC Service are always sent out swiftly to inspect and fix the heating systems (we have turned to this company thrice!). Chris fixed the broken limit switch on the furnace. Once he had inspected the furnace, he got to work with everything he needed. He changed out the machine's limit switch and cautioned us against neglecting it, saying that clogged filters would make further maintenance impossible. Good!

Without a doubt, I would recommend my friends and neighbors to use this service. Thank you for sending us a great technician like Derek. He is smart and acknowledgeable, and he quickly figured out why the Carrier boiler stopped heating water. He was quickly able to fix it. Awesome.

I've been using The HVAC Service for a couple of years and can say only good things about these guys. The service is always excellent. I told everyone about it, so now when my family or friends need help, they go to them. I can recommend this service because I believe in it.

I'd recommend Daniel, one of their techs. He is very good at what he does. He came right away when he got a phone call and fixed a Lennox AC. No questions asked, 5 points.

Excellent work! Andrey is in charge of the installation, and I want to thank him for being helpful and doing a good job. Everything was done quickly and easily. The HVAC Service is 100% the best.

The HVAC Service is my choice. I always go to their experts when I have a problem. A water heater should only be fixed or put in by people who know what they are doing. Dave caught a broken-down Trane boiler in time to keep my house from catching fire.

If you haven't talked to The HVAC Service yet, you should. Don't worry if you don't know which to choose yet. You're in the best place to get help. Last week, Derek tuned up my new Carrier boiler. I've been happy every time.

Technician Derek, thanks for doing a good job. My Lennox furnace is no longer making noise. This company has the best people working for it.

Thank you a lot. How many times have your people helped me with tech issues? Oh, countless, you are my personal magic wind. The last time Daniel fixed a Goodman furnace. While I was away, I didn't worry about my home because I knew it was fine.

This company is without a doubt the best when it comes to getting things done. You can be sure that the work will be done well and that the people who come to your house will do a good job. They only hire technicians who have gone to school and worked for a long time.

Excellent work! My water heater took a long time to heat up. My husband tried to fix it, but it didn't work. I was lucky to have The HVAC Service's number. The repairman came out the same day and quickly and easily fixed the Goodman water heater. We're both happy, me and my husband.

Last month, I was on the verge of saying goodbye to my heater. When I woke up, I discovered a large leak with a specific smell. My boiler began making whistling sounds shortly after that. As a way to alleviate my stress, a friend of mine suggested The HVAC Service to me. I'm hoping that their fix will prevent me from having any further problems.

Having this company in my area is a real relief. Thanks for your quick visits when I have huge problems with my boiler. One day, I could hear noises, another day I saw leaks. If you have the same, I insist that maintenance is a must. Their technician Chris helped us deal with temperature issues, and loose panels. I guess they can approach other boiler problems as well. Besides, their prices are reasonable. No worries.

I was worried about my tankless water hater which produced small leaks, and after, there was more and more water underneath. I didn’t reinvent the wheel and contacted the HVAC Service for a repair. Their expert Daniel approached the problem and told me that there was something with a pressure relief valve. Luckily, it was fixed. No complaints at all.

I needed help with my furnace for worn-out ball bearings that simply deprived the motor of proper functioning. We heard the scraping sounds and knew that it was a sign to consult the professionals. This company upon examining the problem explained to us that no repairs were possible but replacement. I agreed on that, and the issue was quickly dealt with. Al in all, thank you very much.

I am busy and single mom who whenever comes across HVAC system malfunctions always rely on professionals rather than try to fix it all alone. The last time, I needed to check my water heater because of its strange noises. The HVAC Service Solutions was the one I called. Their HVAC expert Sam diagnosed the issue and provided me with the estimates. The whole work took half an hour. Liked the service.

My overall impression of the HVAC Service Solutions is just fine. We requested a visit of their expert for a boiler checkup. It has a little-little leak, and I knew, from my previous experience with these systems, that it was only the beginning of the disaster. He tightened some pipes, and checked the thermostat for its optimal running. The problem was fixed within 40-50 minutes. Thanks.

Clogged filters in the furnace is a common problem within my house, and my parents 'house We regularly turn to plumbers, but once were told about this company. They sent their technician pretty much quickly. He overlooked the problem, and prevented the damage of the switch. As for the prices, I believe it depends on the issue, however, we didn’t pay much. However, again, I truly believe that you should call them whenever you see the first signs of malfunctions.

I never knew that a boiler might have something like a frozen condensate pipe. For me, it was a warm , hot unit, ha. The HVAC service told me that it was good to contact them early, because it could cause a shutdown, and then damage. The expert poured some water on the pipe, alongside some other technical nuances. As a result, my boiler is safe and sound. Thanks a lot.

The HVAC service solutions is a company inspiring confidence on longevity of their repairs. Last time, I turned to them because of a cracked furnace heat exchanger. It was a really costly thing, however, what to do, when you forget about the proper maintenance. Their technician made sure I understood the cost involved, and picked the right exchanger. The whole work took one hour. Thank you very much for your help.

I looked for a reliable company near me that can satisfy my playing capacity with repairs. I encountered the HVAC service solutions, and didn’t regret it a day. They basically prevented me from a boiler major leakage, and double-checked whether heating elements perform their duties, strange it may sound. The prices are fair, not cheap ones and not expensive ones. Good to choose.

Needed a consultation on boiler repair and requested an appointment. What a relief it was to discover my unit didn't need any replacement. They cleaned it, and did some magic, sorry I am not tech-savvy. They don't charge a lot. Totally recommend them to all those hesitating.

Wanted to ensure my air conditioner runs optimally, and turned to the HVAC Service Solutions for a turn up. The team told me that this procedure will reduce any future issues and save my money for the purchase of the new machine. I am satisfied. Thanks a lot.

Last week I bought wholehouse carbon Filtration system in pursuit of making our eater cleaner and safer because my family has little kids. I cannot tell the difference, however my wife believes it really works. Thanks to the HVAC service solutions for your guidance and affordability. Cheers.

After moving to a new house I found out that was no water heater, or it was previously damaged. Who knows? Anyways, before buying a new one, our family decided to rent a water heater with the HVAC service Solutions. The team was very kind to recommend us a unit fitting our paying capacity. Water softener included as well.
