I put the restriction back in the line and ran it as I had before. It worked fine all winter. Kept the garage as warm as I needed it. My longterm plan is still to install a gas boiler that will provide the heat to the garage floor, basement floor, and DHW. As I mentioned before, propane...

So what is different between an electric tankless water heater and an electric tankless boiler? Other than the price tag? I did not purchase the Ecosmart planning to modify it. I checked the suppliers website and it was rated for radiant heating so I figured it should work in such an...

The unit in question is not a whole house heater, that is correct. A large whole house heater was not necessary for this application. The unit in question was rated at taking 70 degree water to 120 degree water at a flow rate of 2 gpm. I am asking it to handle a 20 degree delta T at about the...

When I drilled the hole out to 3/8", the flow meter didn't recognize enough flow to turn the unit on (I will work on a solution for that when I find some time, maybe next week). I believe Fastback on here had success using a Titan tankless water heater by drilling out the restriction on the...

So what? It is a heating source just like many others. If it will meet the heating demand, what difference does it make what heat source you use? It it up to the owner to decide which route is most cost beneficial or meets his needs? Yes they have minimum flow requirements, most...

with one pump or are you using it in a primary/secondary system? Here is your picture that I had originally used, post #122 in this thread: http://www.garagejournal.com/forum/showthread.php?t=49557&page=7 You used a Titan tankless unit, which has the hot water outlet on the right hand side...

I purged the floor lines again with the portable pump, can only get .7-.8 gpm thru each line with it (when purging one line at a time). No additional air came out. The manifold connections for the gardon hoses with the Watts manifolds are kind of cheesy so it may be a restriction? Regardless...

Funny you should ask, I liked your simple setup and built it based upon your picture. However my heater inlet and outlet was on opposite sides so my loop flows opposite of yours. After I built it I realized you had your pump pushing towards the pressure tank and it should be away (so I moved...

In an effort to get my garage and basement heated for the winter (my HVAC system won't be installed until spring), I was moving forward with using tankless water heaters to supply the heat to the two areas. Garage was first, 32x40, I put together a single loop using a Taco 007 thru a EcoSmart...

Awesome. I downloaded the program and have been trying it out for a little while. Very cool to see how things affect the overall heat load in real time. With my design parameters used and only using it as a class 1 snow melt system, i came up with just under 100,000 BTUs required. However, I...

Those are the prices here in Nebraska. A benefit of being the only state that still has 100% public power (no private companys) is that since the utilities are not for profit, the rates stay low. My bill has about $30 for the generic service fee just for having service. I figure I'm gonna...

for winter rates (Oct. 1 thru May 31) it is as follows: 9.64 per kwh for first 100 kwh 8.34 per kwh for next 780 kwh 4.72 per kwh for the rest We use over 3000 kwh every month so I just used the 4.72 for my numbers. Summer is 10.48 per kwh which hopefully wouldn't ever apply for the snow melt...

In an effort to determine the operating cost of a snow melt system I came up with the following using generic guidance: For a 1000 sq ft slab which required 100 BTU/sq ft of heating to melt 1.5" of snow per hour, it would require 100,000 BTU/hr. Since 3413 BTU = 1 kWh, this would require 29.29...

The entire house project is a DIY job so it's taking some time. My local HVAC guy had his experts come check out the house and are doing the heat load calc on it right now. In the mean time I have added about 1000 sq ft of snow melt system out front to add to the requirements. I've done a ton...

I'm planning on using a geothermal system for my heating and cooling needs in our new house (still in progress) and was curious if it could also be used as a heat source for my radiant floor heat? I have 2000 sq ft of basement floor (two zones) and 1250 sq ft of garage floor (one zone) to heat...
