Tankless Hot Water

As most of you may know, I was at the Edmonton Home & Garden Show last weekend with Steve Zaleschuk from Finished Right Contracting who had one of our current builds on display. One thing I noticed he kept repeating to people when talking about our radiant in-floor heating was, “Just because you live in a tiny house, doesn’t mean you have to go without luxuries!” He’s absolutely right, and most people agreed.

People were amazed when we told them that radiant in-floor heating was in our tiny houses. Of course, you don’t have to have it if you don’t want to, but, why would you not? The pros far outweigh the cons.

The tankless propane water heaters we use are from Noritz Canada and save you up to 40% off your water heating costs, last up to twice as long as traditional hot water tanks, and use recycled parts so there’s less waste.

Think of it like this, traditional hot water tanks heat all the water in the tank. Then as the water sits there it cools off. Then the tank heats it again. Then it cools off…etc. Traditional tanks heat water when it’s not even being used. Tankless systems have hot water on-demand. It only heats water when the taps are turned on and you need hot water.

The systems we use have two separate outputs. One is your domestic water for showers and doing dishes, and the other is for the in-floor radiant heat which contains glycol. Both are set at different temperatures too!

The only con really is the up-front cost. The system costs around $4000, but the amount of space and money you will save on heating costs make it well worth the initial investment.

  1. That looks really cool! I am interested to see how it works out for you. I may try and do some radiant heating in our tiny house by pulling some heat off of the wood stove and piping it over to the bathroom which is at the far end of the house and gets a little cool in the winter. Although my to do list this year is getting to be pretty full so I am not sure if it will actually happen.

    How much insulation do you have in the floor below radiant heat? My only concern is that a fair bit of heat would be wasted but maybe not?

    1. We have 3/4 T&G fir plywood beneath the radiant pipes. Under that we have 3.5 inches of spray foam (or more) which gives us great insulating value.

  2. So the question becomes, how well does radiant floor heating heat up a tiny home? I have only dealt with it once in a regular house and it did not seem to do much other than keep floors warm….

    1. It works really well in a Tiny House because for one, the area you are heating is much smaller. It also works well because the entire floor warms up and that heat rises to heat the room. With forced air, the warm air is actually forced up and no where near the floor, resulting in warm air on the top half of the room, and cooler air on the lower half.
