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.
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.
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.
Brilliant idea. One question was concrete the only option?
We are going for a thermal mass heat bank that should keep us warm over night, there is only around 200kg of concrete so weights not a problem. Let’s just hope it works.
