Is this a reasonable price?

Hi,

We are building a detached garage - total dimensions of 32x34 feet. The floor will be poured concrete. The garage will contain partitioned space for our laundry room, a dog room, mud room, pressure tank/controls, solar water heater controls, hot water tank and possibly a small work bench space. The space is 8X34 feet. The other side of the partition will contain a large two car garage with storage along the wall and possibly a small work bench space. The garage doors will be 12’ wide and 10’ tall. The space is 24x34. Since it’s a new slab we are interested in going the radiant floor heat route. We would like to run a couple of loops in the car garage to maintain an above freezing temp for storing liquids. The partitioned room containing the laundry area would have to be well above freezing. We would also like to run a loop on the concrete apron for the garage to melt ice. I may use the work bench and garage to service my tractor and vehicles. I would consider this infrequent use – in other words it’s not a full time shop. I am pretty comfortable working in 45-60 range anyway. My thinking is that I could always uses a propane direct vent heater to provide a “boost” if necessary. Initially I would probably take a wait and see attitude as the hydronic radiant may be enough.

Also, I just received a quote on the Radiant for the garage. He quoted me an estimate of $7-$9 a square foot. His package would include installation of 2” foam board under the slab, 6” wire mesh, tie the tubing to the mesh at 9”-12” centers, install the sensors, boiler, pump, controls, glycol filled system.

Does this sound like a reasonable quote? We live in Redmond Oregon.


Thanks in advance,

Bill

Which comes to approx $6500 for your heating system
I've had a couple of the online material "quotes" returned to me for a 32x48', both came in at around $3500 for materials, including the heat source(lower end models), obviously if I go to a $3000+ heat source the price will be higher.
If you can do the install yourself you'll be way ahead, if not you're in the unfortunate position of being at the mercy of the contractors.
The labor on the in floor system is pretty easy by anyone's standards, take that into consideration.

Thanks for the reply. That's a reference point I should have researched before my post! Good info. Sounds like you were able to get quotes for a "package". Who did you use?

Thanks again,
Bill

2 places I've gotten quotes from:

http://www.radiantec.com/index.php
http://www.radiantcompany.com/

Not endorsing either, just came across the quote request forms on their websites.

Depending on your choice of heat source, I can help you with DIY packages in the following price ranges for a 1088 SF project:

Standard Electric Water Heater: $2.20 to $2.50 per square foot.
Standard NAT or LP Water Heater - $2.55 to $3.00 per square foot.
Electric Boiler - $4.00 to $4.75 per square foot (high eff.)
Oil fired water heater - $4.15 to $4.65 per square foot.
Higher efficiency (94%+) Nat or LP Sources - $4.75 to $6.00 per square foot.

If you'd like me to put a fair and firm quote together for you (no cost or obligation) just click here:

My bottom-line goal is to provide people with a DIY radiant heating solution that is simple, efficient and cost effective.

I recently posted a page with pictures from my in-slab radiant heat project here:

I hope that helps you as you move forward and make decisions about your project.
