My New Navien Tankless Water Heater

Tankless Hot Water Heater

My wife and I had a new Navien tankless hot water heater installed at our residence on 5/14/09. We had been considering exchanging our old hot water tank for something much more energy efficient for a while now. The new tankless heater has been in use for about two weeks now, and we are more than pleased! It is comforting to know that the heater is not just sitting there, heating up water when it is not needed. In fact, it does absolutely nothing until a demand is put on it. The other great thing is the tax credit we will receive from the Federal Government for installing an energy efficient appliance!

We have 4 adults living in our house, and we have yet to run out of hot water from the heater. It is not uncommon to have both showers in use, and be running the dishwasher and washing machine at the same time.

We are going to be tracking energy savings on our gas bill in the coming months, comparing the same months from last year to these next 12 months.

Join us as we track our bills online!

A couple things to note on these bills. in 2008, we had 3 adults in the house. This year we have 4 adults. We have a significant demand increase, but our bill is 50% less!

May 2008, $27.92. May 2009, $15.85

June 2008, $36.88 June 2009, $18.39

July 2008, $30.89 July 2009, $16.18

August 2008, $25.87 August 2009, $18.06

On a side note, It should be pointed out that you could obtain an even lower gas bill if you chose to go with a standard tankless unit. Due to the distance from the heater to the kitchen Jack decided to go with a recirculating model. They use a bit more gas than the standard. I suspect as much as another 50% drop in his bottom line.

Personally, I love tankless water heaters. It seems to me that the people who are having trouble with tankless water heaters, didn't buy the right type of water heater for their needs, or they didn't install it properly.

In other words, after turning on the hot water at a fauce it takes considerable longer for hot water to reach the faucet than in does with some other tankless water heater. This person said these complains were not isolated.

What is you experience? What are you thougth.

Thanks

Jim

PS This person said the heater is great if you can live with this "delay"

All tankless have to purge the coil, before you get hot water. 1/2 a gallon seems like more that I would expect. the .5 gal would purge in about 30 seconds in most lavatory faucets. Ironical the Navien is the only tankless that offers the internal recirculation that keeps the water hot so there is no delay. It seems that your friend did not get this model, or he is not set up correctly. The down side to the internal recirculation is it has the heater working when you are not using water. You should look into the High Efficiency Rinnai. These are very nice units, and If you are not planning on a recirculating loop they are probably the best product out there.
