Radiant floor heat

Can you use a hot water heater to run radiant floor heat instead of a furnace? Not the only heat source, just in one or two rooms.;)

Yes it can be done.:)

Re: Radiant floor heat

Thanks, now I will try and figure out how to plumb it, need to know when to put water in, don't know if some will evaperate or not.

Re: Radiant floor heat

Canuk is correct.

But try to get as much background info as you can before you dive in to this, because the parts and supplies can be expensive.

Make sure you include a PURGE STATION for your PEX piping arrangement so that you can vent the air pockets out of the tubing.

Air pockets in the PEX tubing is a common problem in radiant floor heating.

Some of the radiant floor installation companies offer a free installation manual (sites below) that are very helpful in designing your system.

Many of them want you to buy a fancy-dancy stainless steel Polaris HWH that goes for $3500.

You can buy a whole boiler for $1500 at Home Depot.

Also check out "Modern Hydronic Heating", 2nd edition, by John Siegenthaler at the library; it has several easy-read chapters on radiant floor installs.

Also Google "Hot water heater" radiant floor heat to get numerous sites that deal with this topic.

Call Radiantec toll-free for free manual at 1-892-626-5564 and Radiant Floor Co toll-free at 1-866-927-6863.

Be aware that many towns don't allow you to combine the HWH for radiant with the domestic taps for potable water use.

Be sure to let us know how you make out.

Thanks for the info, will look into all equipment I will need for this project, have other heating options to look at. At 61 I might need a little help with this one! Thanks again:rolleyes:
