|In response to Re: Takagi tankless water heaters|
Eileen, I also installed a TK-1 and had the same problem. Now I wish I had just installed a 70 - 100 gallon water heater. When I first turned my TK-1 on, it could not keep up with the hot water demand of the shower. Consequently, we would regulate the shower water temperature with only the hot water valve (this was after changing to a low flow shower head).
Also, because my shower is on the second floor and the TK-1 is in the basement, there was a time lag of feeling the water temperature change when adjusting the hot water (maybe a couple of seconds). My family would adjust the hot water many times and never be able to get the proper temperature.
Here I'm tring to do a home improvement and the family is now revolting against me(where is the compassion)- I refer to it as "The Great Hot Water Revolt of 2000". So next, I by a 50 gallon hot water tank, an aqua stat, a grundfos pump and create a 50 gallon hot water holding tank using the TK-1 to heat the water. I can send you a diagram (plans) for the set-up. I now have about $1600+ dollars (me doing it myself) invested in this thing, but the family is happy.
Now, I only have one problem to correct. When a valve opens (toilet, dishwasher washer...) there is a knocking in the pipes. Notice I say when valves open this occurs. I have been in the house for 10 years and this never occured prior to installing the TK-1 with associated holding tank.
Recomndation: I live in MI and the water coming into the TK-1 is too cold for the TK-1 to make 5 gallons of hot water per minute. I get less that half that. Return your unit and get a hot water heater. In Japan, where the population is 100 people per square inch and water is at a premium, it works fine. However, that is not what Americans are accustomed to. At the first sign of problems, I am going to throw the TK-1 in the garbage and get a big ol'hot water heater.
