Rinnai tankless water heaters
Why Choose Rinnai Tankless Water Heaters?
When opening a hot water tap, or starting the dishwasher, the Rinnai tankless water heater recognizes the need for hot water and starts the heating process. The temperature of the incoming water is used to calculate how much heat the burners must produce to deliver water at the desired temperature. When the demand for hot water ceases, the unit shuts down and uses no energy, waiting until more hot water is needed. The end result is hot water that is not limited to what’s available in your tank. You always have clean, hot water when you want it for as long as you need it!
How Much is a Tankless Water Heater?
In general, the purchase and installation costs of a tankless water heater can be 2 to 2.5 times as much as a conventional tank-style water heater. However, energy savings with a tankless water heater typically result in a payback within just a few years for a family of four, making a tankless water heater a better long-term investment.
Three Ways Rinnai Tankless Water Heaters Saves Money
1. Lowers Your Energy Bill
Rinnai tankless water heaters reduce energy consumption by up to 40%. They heat more efficiently and only heat water when it is needed, avoiding standby loss.
2. Conserves Water
The compact design of a Rinnai tankless water heater allows flexible installations located closer to fixtures and appliances. This reduces the wasted water while “waiting” for the heated water to arrive.
3. Buy Only Once
The service life of a Rinnai tankless water heater lasts up to 20 years. That is 2-3 times longer than traditional tank water heaters. They are also significantly smaller in size, using less material and reducing what may end up in landfills.

We had a great experience with Nick and his team on the repair and maintenance of our furnace and radiators. I called multiple companies that told me they couldn’t come out for a month+ and Nick came by the next day to take a look at our furnace and they started the work the following day. Our furnace is 26+ years old and it required some new parts and a lot of maintenance. The team was extremely detail oriented and never rushed the job. They ended up encountering some additional issues and worked on the problem until it was complete. They were all extremely professional and nice, and they communicated with us every step of the way. We will definitely be using them for all of our future heating needs.

Love the services we've received from JM Plumbing and Heating. Dimetri has been our service tech twice now and each times he's been expidiéndote and super knowledgeable. I've appreciated how responsive Nick has been whenever we've had a concern as well and they've always been on-the-money with the recommendations. Great prices as well!

We contacted JM out of desperation because the previous company could not figure out what was wrong with our tankless water heater. Nick was amazing. He came to our home that same day and had the entire system working properly. These guys are our new plumbers from now on. Very professional and compassionate. We did not feel like just another client, they made us feel special.

For various reasons having to do with the particular space in our house where our old water heater was located, we were having a really tough time finding a company that could replace our tank water heater with an electric tankless. JM was incredibly responsive right off the bat, listened to our questions and concerns, and did incredible work. We're really happy to have worked with them and appreciate their professionalism and quality work! Will highly recommend them to others in the future.
