Hi,
New to this site and was hoping I could get some opinions on the Synergy 3D system. Does anyone out there have this dual system? Do you recommend it? Is it worth the extra money to go for the dual heating methods or should a person pick one (forced air or infloor heat) and go with the single method. Also anyone that may have this dual system hooked up , do you find the electric bill still make it worth while and cost effective? Basically i am looking for some input, and advice as the most comfortable way to heat a house as well as stay green and and cost effective. At the end of the day infloor heat is nice, but so too is the A/C available through the forced air , so was really intrigued by the Synergy 3D system which has both.
Any input would be greatly appreciated!
Thanks everyone

Curiously the lions share of the equipment complaints are with systems that make hot water as well as warm air. Water furnace is newer at it, but we've heard grumbling about their handling of warranties lately.
If you wish to go the way you describe, you might get with a local DX dealer, or go with a water to water geo.
Good Luck,

We are getting ready to install this exact unit in our home/shop. Our contractor has been installing geo for 25 years and has several Synergy units in the field. He is confident that it will do exactly what it is supposed to do. He even says it is best of breed because it allows you to shut off the floor heat in the spring and fall, and use forced air heat if needed, since here in Iowa the temperatures can swing quickly that time of the year. I will have more experience with it in about a year.

We just installed one too. Hope it works as good as they claim.LOL

any updates? I'm interested, too.

The key to the Synergy is proper design and installation, as in any system.
Adding the load water side into the equation makes this more of a challenge.
Pick your installer carefully.
WF has been manufacturing the Synergy for 12 years now.
 

Our guy is good. he's been doing it for decades and installed 300+ WaterFurnace units. He has the Synergy in his home, too. On paper it's less efficient than the Envision but my basement will be a family room someday, and forced air from the ceiling seems like a much inferior way to heat the basement comfortably. Thanks for the help. I'm leaning toward Synergy. I was just scared by some threads here.

I'l throw my hat in here also. I'll be building this year with ICF and would like radiant in the basement floor and in at least part of the main floor. Still thinking about what method to use, warm board or 1.5" thin slab. Here in central Illinois we have to have the central air so we still need to move some air be it warm air or cool. One concern is how to set the thermostat(s). One for setting the floor temp and one on the wall for the air portion? I don't think I would plan on using the radiant for chilling in the summer.

http://welserver.com/WEL0267/ Happy camper so far. Yep, 2 thermostats would be the way to go. you need to tell the Unit what to prioritize on, radiant or forced air heat. The radiant part conditions a buffer tan, larger than normal, and then a simple thermostat turns on the circulation pump for a radiant floors. The forced air is through a 3-stage thermostat...actually quite simple. No radiant for chilling, too much risk of condensation. Check it out above...

As an installing contractor and reading the comments above you can only appreciate the ability to do all three things from one unit, It greatly minimizes the installation costs associated with a water to water unit and the chilled water lines that you have to deal with due to condensation problems. radiant basement or main level too this provides what many applications are requiring these days. Using a buffer tank with electric back up when needed and locked out when not needed is essential to providing the savings that a customer is looking for as well as backup or emergency heat if that comes into play as well. installing a Tekmar 152 controller is a great controll for minimal amount of money to lock out the electric element with the 1st stage sensor and then using the second sensor allows you to sense the load out to be sure it stays where you want it, use the timer in the control to allow enough time for catch up to happen before you finally energize it.

We have it and it good. This is our first winter with it. Brand new house in Ontario, Canada. We are using about 112 kwh a day for a a 4500 square foot house. That heat and hydro for 2 adults and 3 kids
