Pros: Somewhat reliable
Cons: High electric bills and high cost of service calls
I have owned this unit for few years now and recently when I installed energy meter in my house I found that this unit consumes over 4000W of electricity when it turns on - same as my electric water heater..
I thought that geothermal was much cheaper to use - is there something wrong with my Tranquility 27 unit?
So far some electronic board was replaced because it was browning from overheat and one of the loop pumps had to be replaced. Service calls are expensive and watch for the companies that send serviceman with a helper - you will get billed double for 2.
