The DIY Energy Efficient Home Project Magazine By EcoMaster


Learn from award-winning experts, Lyn & Maurice Beinat at ecoMaster on how their astronomical energy bill was the catalyst to two decades of research, product development and trial and error in the search for the most economical way to make their home more energy efficient on a budget.

Fast forward to today, and their home is now a 7.6-star energy rated home with zero energy costs and carbon emissions.

ecoMaster is here to show you simple, practical DIY projects; room by room that any DIYers can do. It was all filmed at the ecoMaster test home in the Macedon Ranges, Victoria, Australia.

Smoke Alarm &

Insulated Hot

Water Pipes

to the tubes, and it comes back this way. So actually, I’m just

going to test the difference in the temperature here. Pretty hot.

Ouch, really hot. So, it is a sunny winter’s day outside. And so

those evacuated tubes are definitely working fantastically well.



one after the other, and glue them up under the galvanised

deck. We used water-based liquid nails to do that. They fitted

together just like a jigsaw puzzle, making little still air pockets,

which you need for reflective insulation to work properly. So

that’s what we did and it’s still there and working today.

Firstly, we decided to put a smoke alarm up here because

if there’s a fire that happens to get started in the roof, this

is likely to warn us a long time before a smoke alarm in the

house would do.

The other thing is the hot water system here. We’ve got a

low-pressure copper tank with 400 litres of very hot water. So,

this hot water pipe here is pretty well insulated. And this is the

return from the tubes on the roof. Down below here, we’ve

got the flow to the tubes on the roof. So it goes out that way

Because this house is a slab on stumps, it gave us the

opportunity to insulate under the concrete slab. It’s great

thermal mass but not a very good insulator. So normally under

a floor, you would use the polyester rolls between the joists,

which are fantastic. But under this floor is a galvanised tray

that was used to pour the slab on top. And so very difficult to

fit any kind of bulk installation to that.

So what we had to do was invent our own insulation and we

decided to use reflective insulation. So you can see here we’ve

got 15mm Foilboard cut into 600mm tiles and fitted with this

25mm border on two sides. What enabled us to lap them

R2.5 Underfloor Insulation


Insulating The

Cathedral Ceiling

We’re currently in the roof, looking over the cathedral ceiling.

And what we can see here is the original fibreglass bats laid

on black plastic over the cathedral ceiling, and then on top,

we’ve actually fitted R2.5 Underfloor Insulation Rolls that were

pulled across the cathedral ceiling. You can also see that

while the cathedral ceiling actually holds up the roof, it is not

the roof itself.

Draft Stoppa

We are over the bathroom now, and specifically, we’re

looking over the exhaust fan. This is a Draft Stoppa that’s

fitted over the exhaust fan. It’s got two flaps that are pretty

carefully weighted. When the exhaust fan is on, they tip up

and the moist air comes out. When the exhaust fan switches

off, they just fall down. Now you can probably hear that

clickety-clack sound that they make. This is an old model.

The newer models have got little rubber bumpers on them

so that they don’t make that sound.
