I have been given a quote with the Quietside dual purpose water heater DPW 099A to replace our heat/hot water tank in a condo. The quote for the unit and to install it which includes a new coil and drain plan is $4,500-5,000 US. Two questions: Is this a good product? Is this a reasonable price for what I'm getting? I've seen the unit for sale online for about $1000 US. Part of my hesitation is that I live in Canada and Quietside has limited business in Canada. Concerned that servicing could be a problem.
