  • Perfect! Just perfect!

    My husband and I bought this for our double shower head shower and it works wonderful! It's so nice to be able to do the dishes and then know I didn't waste all the hot water (I can even do the dishes while my husband is showering.) We run the wash machine at the same time as the showers too and it's no big deal. Don't forget to get the piece that goes with it to install!

    I have this water heater and it is fantastic. Quiet, powerful and efficient. I can take a shower, wash clothes and wash dishes at the same time. I can fill my jacuzzi in one shot now. I don't have to wait for the water heater to catch up. I wish I had purchased this much sooner. Great price here too.

  • Really nice!
    Verified Purchase

    It really is more than what we need at the time but, my husband said once we build we can use this for our laundry/guest bath. We had to learn that there really isn't "instant" hot water as with a water tank. We also never realized how often we turn the hot water on just to rinse our hands or dishes. We're finished washing our hands before the water gets hot... hence a waste of propane! Like my husband says it's a learning experience. Love that I can be in the shower without worrying if I'll run out of water! Plus I can take my time and my husband will still have hot water for his shower!! LOVE THAT!

  • Eccotemp Propane Tankless Heater
    Verified Purchase

    Purchased a small cottage that had an electric hot water heater in corner of the bathroom. The electric heater took up most of the bathroom. In July, replaced the old electric with the Eccotemp 6.3 GPM Liquid Propane Indoor Tankless. Put the new heater in the laundry room now the bathroom has so much more room. The Eccotemp works like a champ!!! Heats the water quickly. We are very happy with this product. We would definitely recommend this product.

    So glad to finally get rid of conventional water heater and go with this. For those who want instant gratification, you might be a tad frustrated w/ waiting the 20 sec or so it takes for the water to come up to temp, but that's so minor compared with the amount of propane you don't use and the money you save. Also, the temp on the unit is easily set to whatever the task at hand requires. I usually keep it on 117 degrees because I like hot baths. For washing the dog, I can set it to 105; something that needs a really hot washing, 130. Excellent unit. You don't have to pay the big bucks for a Rinnai.
