"I used to think of buying a boat"

1.0 rating
Very Unsatisfied

I used to think of buying a boat was the most expensive way to spend your money until I was talked into a WaterFurnace Geothermal HVAC. The installer has disappeared and the WaterFurnace people just tell me to call local installers but first ask if there is anyone that they shouldn't recommend. The cost per month to heat my home in Michigan is outrageous. Then there are the multi-year repairs now that my system is 8 years old. Always needed repairs but when it was new it only needed repair every other year. Now it's multiple times per season. Take your money and heat your home by burning it in your fireplace before buying one of these geothermal systems!

"Love my geothermal system"

5.0 rating
Very Satisfied

I just want to say that using a waterfurnace HVAC system in our home build back in 2007/2008 was one of the best decisions we made in building our home. I read some of these other reviews giving the system bad reviews. What I have noticed is that it seems to me that their installers were the majority of the issues and not the Water Furnace system as the issue. Our only issue with our system was back in the beginning the thermostat controller going out which was under warranty. But other than that it has worked flawlessly. I did a lot of research before deciding on going with a geothermal HVAC system and I would do it all again in a heartbeat. The system does what they claimed it would do and it saves money and is literally maintenance free other than cleaning or changing the air filter. I think the only thing I would change would be to have gotten a system that does force air and hydronic heating. I wouldn't hesitate to buy another Water furnace product in the future. I believe that they are the top company in the geothermal HVAC systems.

"Mechanical Breakdowns"

1.0 rating
Very Unsatisfied

We have had a Water Furnace Geothermal system for 10 years. It breaks down every six months. My electric bill runs over 700 dollars a month. When it is not working I run electric space heaters., My electric bill dropped to 225 a month. Don't waste your time or money with geothermal. It's expensive, unreliable, and is no way energy efficient. It is not good for the environment either.

"Geothermal Heat Pump"

5.0 rating
Very Satisfied

It's been all it was advertised to be. I've kept meticulous records and the average monthly utility bill has been $175 (for a 5,000 sq. Ft home). That includes heating, air conditioning, hot water, lights and appliances. I've looked at other manufacturers and in the end, found they did not have the package WaterFurnace does. I'm a big fan of WaterFurnace.

"Boring, but satisfied"

5.0 rating
Very Satisfied

I am reviewing a WaterFurnace NSW050 water-to-water geothermal heat pump, configured to deliver heat or cooling with a desuperheater to preheat domestic hot water. I have a closed source loop with 167 feet of well depth per ton of heating/cooling. It is custom configured with an external controller for easier use. I had it installed 7 years ago to replace an oil burner and air-to-air a/c unit. The best word I can use to describe this unit is "boring." It does what it is supposed to do reliably and without fuss. My system requires no maintenance, and it is easy to switch between heating and cooling modes. The only problem I have to report is that the Intellistart burned out near the end of the warranty period. Moving one wire allowed it to work until the replacement part arrived. I replaced it myself at no cost. My only two complaints are minor: 1. The insulation surrounding the heat exchangers, out-gasses and irritates my respiratory system, but this is only a problem when I have the unit open. 2. (technical) There is only one freeze point detection setting, so I have to change it when I switch from heating to cooling and back. Otherwise, I could do it with the flip of a switch. Overall, I am extremely happy with the unit, and I highly recommend it.
