OUR 1983 PROJECT caravan had a Carver 1800 space heater – which had stopped working long before Practical Caravan bought it. Truma bought Carver in the 1990s, and the 1800 is long obsolete, so we decided to replace it.
I decided to fit a new Whale space heater in its place and, despite a delay in obtaining the new unit, I went ahead and prepared the bottom of the wardrobe to receive it. I fitted a plate to cover the hole in the floor where the old space heater had been.
Removing the Truma space heater was easy. I undid the four screws securing it to the floor and cut the 12V cables. The gas connection had corroded so badly that I had to cut through the 6mm copper pipe. I then lifted the heater out.
The back box was also easy to remove. My intention is to make and fit a door in place of the heater which will create an extra cupboard under
the wardrobe. But the immediate job was to fill in the hole in the floor.
The hole in the floor measured 15in x 5in. I cut a 20in x 9in piece
of 6mm-thick plywood and ran non-setting bedding mastic around its perimeter about one inch from the edge.
With the tourer on the lift, I was able to screw the plate to the floor.
I then sprayed the plywood underside with a coat of matt black paint to protect it from the elements.
I wanted the top plate to be level with the existing floor. To accomplish this, I fitted three pieces of wood 6mm less in depth than the depth of the hole and used adhesive sealant to secure them to the bottom plate. I then filled the gap between them with polystyrene insulation.
I cut a piece of 6mm-thick plywood to fit the hole and screwed it to the three wooden bearers. In due course I will probably cover the wardrobe floor with a piece of vinyl.
