We are going to have under floor heating

The old walkway needs filling in

As this will be our home we had the a thought of under floor heating, not a bad thing when living in the colder area’s of Australia. We will be putting in a KIMBERLY™ Wood Stove with a heat exchange unit in to heat a 50-80lt hot water tank, then the hot water will be pumped through pipe work under the floor, so keeping warm shouldn’t be a problem. The thermal mass heating idea looks the best for us, as once it’s warmed up you can leave it off over night. I’ll all so run a thermostat to turn the water pump on or off  while it’s running so we don’t cook our feet.

Now where is this going to going???

 

Cutting up and painting the form work.
Form work screwed and glued into place.
Plastic pipe supports in place and water proofing painted on.
Inlet and outlet holes drilled into the floor.
Pipe work in place.
Looking from the back.

Concrete time fun fun fun……. not !!!

It’s not that bad as it’s only 4400mm x 300mm x 110mm so only 0.13m3.  This is going to be a strong mix one bag each sand, gravel and cement with a water proofing agent mixed in. I’m going to make the mix as dry as possible, this will make it as strong as I can.  I’ll also be using a concrete vibrator as this will get all the air bubbles out of the mix. Now it’s time to start mixing in the wheelbarrow then bring it in one bucket at a time into the coach.

And the concerting starts.
One bucket at a time.
Just need to go over it one or two more times with trowel.
That’s one more job done.

We will be leaving the formwork in place to insulate the concrete and have a 100mm gap down one side, that will be used for air flow later on to circulate air up the back of the motorhome. As you can see we are making things up as we go along, but it’s the first time we have made anything like this and it will be a one of a kind coach design.
