Finally replaced our old tank water heater with the John Wood JWT-540H-N and couldn’t be happier with the change. The biggest difference is having hot water whenever we need it without waiting for the tank to recover.
The unit is compact, quiet, and works very efficiently. It also freed up a lot of space in our utility room compared to our old traditional tank.
Great choice for a family home. The performance has been excellent so far.

After researching several tankless options, we decided on the John Wood JWT-540H-N, and it was absolutely the right decision. Living in Canada, having a reliable hot water system during the winter months is extremely important, and this unit has performed perfectly.
The 10 GPM flow rate gives us enough capacity for multiple showers and regular household use without the temperature dropping. We previously had issues running out of hot water in the morning when everyone was getting ready, but that problem is completely gone now.
I really like the design of this water heater. It is wall-mounted, takes up much less space than our old tank, and the electronic ignition means there is no standing pilot light constantly running. The condensing technology and high efficiency were also important factors for us because we wanted something that would help reduce energy waste over time.
The installation went smoothly, and the system has been reliable from day one. The water temperature remains consistent, recovery is immediate, and the overall quality feels much higher than that of our previous unit.
Very satisfied with this purchase and would recommend it to anyone looking for a long-term hot water solution.

Excellent tankless water heater. We upgraded from an older storage tank system and immediately noticed better hot water availability and more space in our basement.
The John Wood JWT-540H-N provides steady hot water, runs quietly, and feels like a well-built product. We especially appreciate the compact design and the fact that it only heats water when needed.
A reliable choice for Canadian homes. Very happy with the performance and overall quality.
