Tiny House Update: Radiant Floor Heating Install

We have the radiant in floor heating system installed and wanted to share!!!

It was a learning process for us as we installed the WarmBoard – the structural subfloor panels with water tube grooves. They are from a local CA company, based in Los Gatos and make a great product. AT Weber, our local trusted plumbing company, came in and installed the Pex tubing, on demand Takagi hot water heater, and additional necessary parts.

On some panels, we had to make custom routes (below)

  1. Will you be using one unit to heat your floors and your water or will you use separate units. The one picture of the heater looked too complicated to be just for the floors. Have you tried these out now? How is it working out for you? Would love to hear an update!

    • Hi Natasha – thanks for writing us! We decided to use 2 on demand hot water heaters. One is for the domestic hot water and one is for the in floor radiant heat. It has worked out very well. However as with all on demand systems it does take up to 20 seconds to get hot water to the tap. Cheers.

  2. Thanks for sharing this. Can you share how much energy it uses? Is it running all the time or just when in use? I’m trying to figure out how much backup power you need in a battery to power something like this. Thanks!!

    • Hi Spencer. Well this is for our small house that is grid tied and not on a trailer or battery powered. Other than that, the radiant heat only uses energy when it is turned on/when it is running. Our gas bill is extremely low I can tell you that… about $8-$20/month and we run 2 on demand water heaters (one for the floor heat and one for the water), gas stove top, gas clothes dryer. Hope that helps!
