Hydronic vs Low Voltage Radiant

John Reist

I am building a log home this summer and considering radaint floor heating. I have been considering a hydronic system, but resently came across low voltage systems. Low voltage looks good and easy to install . The question that I need to know is how is the operational cost compared to hydronic using a propane boiler.

Does anyone have experience with low voltage system and wind power or Photovoltic?

Hydronic is more flexible...

I'd consider the hydronic system just because it gives you more flexibility re: the fuel source. You can only use electricity with resistance heat... Granted, electric resistance mats may have a lower initial cost, but that approach may come back and bite you with very high operational costs later on.

Besides, it is much cheaper to heat using hot water from a solar array than electricity via PV panels. You'll need far less panels for the same amount of heat. So, I'd use a hydronic system unless there are some ridiculous grants available in your neck of the woods that allow you to install PV for little cost.

Propane vs electric hmmmm

Depends on your electric rates in your area. With propane at such a premium, I would suspect that electric will be the way to go. But..... price per kwh is the tell all.
Just noticed Constantin's comment. I agree with that, gives you flexibility down the road, also if the cabin is in remote location, you could put a simple back up heater in just in case of power outage w/ battery or generator backup to power a gas heater.
See attachment for idea?? Just a thought, Tim

Electric radiant

In my experience,in most parts of the country the electric rates are cheaper per btu than propane. You must compare all the costs when comparing the two. Cost of the fuel/btu. Cost of installation. cost of maintenance. Cost of the electricity to deliver the btus on the propane side. Also the fact that there is no freeze issues with electricity. To the heating system that is. The electrical is also cotrolled to each individual room. That = controllability. No I don't sell low voltage elec. But yes I do sell 120v. And I do see advantages to electric.
