Question: What is the minimum temperature that it can be set back to?
Document: This heater is tops for a 35' x 15' ground floor rental studio with bathroom that has 2 exterior uninsulated walls. After checking the specs on a number of gas and electric heaters (including Williams), this one installed easily, is whisper quiet, and warms the entire unit and adjacent bath and closet in minutes. Its multi-stage gas burner and fan apply just the right amount of gas and forced air to raise and maintain the temperature for pennies.
it took some time to install it but it was worth the effort. It's ery effecient and quiet. Good product.
Well worth the price...Love my Rinnai :)
After researching, my engineer husband found this heater with the best price on Amazon. We got it for our log cabin and were having a larger furnace installed next door. The owner of the furnace company said his customers never had problems with the furnace we got from Amazon and he considered it the best around.
Answer: no
