How Does a Tankless Water Heater Work?

01. When a hot water tap is opened, the tankless water heater detects the flow
02. The flow sensor activates to determine the amount of hot water needed
03. The igniter activates
04. The gas control valve opens to supply the correct amount of gas
05. The fan and venturi activate to provide the correct amount of gas and fuel
06. The premix burner ignites providing a flame to heat the water
07. Cold water is pre-heated in the secondary heat exchanger
08. Pre-heated water passes from the secondary to the primary heat exchanger
09. The unit determines outgoing set temperature and adjusts the flame to heat the water
10. Heated water moves to the buffer tank
11. Desired hot water amount delivered to the faucet

Hear it from our customers

“Mango was able to provide same day service to replace our water heater. He was very professional, very friendly and was able to locate a Bradford White water heater that we researched and feel confident will be a good choice for us. He did a very good job.”
Wayne E.
“Melissa was fantastic! She had great customer service and was very efficient. We are so grateful to be able to get our hot water tank fixed in such a timely manor. We will absolutely be recommending her and your company to others!”
“One of the best companies I have dealt with! Highly recommend Papa Grant Mechanical for all your plumbing and heating needs! They are 100% reliable and provide exceptional customer service.”
Amrit K.
“Mango came super fast and went above and beyond to clear our blocked sewer line. We will definitely use these guys again for any plumbing or HVAC work we need done.”
Jay B.

“During a visit to our house to install detection equipment, we found a water leak. It was our water heater. On the same day, Papa Grant Mechanical was able to remove the old water heater and install a new water heater. Thank you for your quick and professional service. I would highly recommend them for any plumbing requirements. They are timely and cost effective too. Much appreciated.”

Breakthrough Business Insights

“Mango, Karan and the team did an exceptional job. They installed a dual fuel system (heat pump and high efficiency furnace), tankless water heater, water softener, thermostat and humidifier in my home, replacing the old and defective equipment that was previously in place. All at what I felt – after doing a lot of research and getting multiple quotes – was a very fair price.

The end result was a nice clean install, and as a homeowner the sense that the job was done to a high standard. They took all the old equipment away and left the space clean.

I’m happy with my choice to go with Papa Grant and would strongly recommend the same for anyone needing plumbing or HVAC work.”

Cameron Spurr

“On a referral from a friend, I gave Pap Grant a call for quote. They were quick with eh quote, very friendly and ended up being slightly better pricing than Costco. Installation was done very well and everyone was polite and efficient. AC unit is running great. The guys had great advice and suggestions and would definitely recommend them to my friends.”

Brett Johnson

“Overall incredible experience. From the superb customer service over the phone with Susan, to the 24hour advance reminder, and the timeliness and professionalism of the team on site, I honestly could not have been happier with Papa Grant Mechanical.

Extremely professional, courteous, and respectful all around.

Easily higher than a 5/5 if that was possible. Thank you so much :).”

Jeremy Hunter

“Papa-Grant saved us again! On the coldest day of this year our old furnace quit working. We phoned Pap-Grant to get it repaired. They were onsite within a couple of hours. Although our 48 year old furnace may have been repairable we decided to upgrade to a new energy efficient furnace. The next morning Karan arrived with a new furnace and worked very hard to get it installed in a very professional manner. We are very appreciative of the Papa-Grant team and the work they did.”

Trevor Williams

“Very good customer service . We got a quote on a heat pump. Turned out the unit he quoted us on was on back order. Cary got us a better unit for the same price. Installed the next week . Always available for questions.”

Brews Dalton

“We used Papa Grant to install a ductless AC unit in our condominium complex where connecting to our internal furnace and air flow was not practical. They quoted and installed for us a Daikin AC unit which was installed on our deck and has turned our very warm condo unit into a marvel of cool air for the hot days we have since experienced this summer. The Daikin unit is very quiet and has functioned very well to keep our entire living space cool with much less noise that running portable AC units. Papa Grant was able to do the install in a single day including running a new 220V electrical circuit from the back of our fourplex condo to the front through the attic crawl space. All work has been very well done at a very reasonable price and just in time to handle the warmest weather we have had to deal with this summer. 100% recommendation of their service for the installation and AC solution for us.”

Paul Gifford

“Papa Grant team is very professional and responsive. I am satisfied with their service; I have both my AC and heating system installed by them.”

Simret Gheb

“We had an issue with the toilet and were able to get an appointment first thing the next day. Mango fixed the issue very efficiently. He was knowledgeable, friendly and professional, and fixed the problem in no time. Would definitely recommend.”
