Ceiling Heating - Nursing Home
This was an existing Nursing Home, where the buildings were gutted and then rebuilt internally.
The work was done in a number of stages.
Stage 1 :
1991 |
Installed Load - 146kW. Comprising 65 Units, Lounge Areas, Dining Areas, Offices and Entry etc. |
Stage 2 :
1992 |
Installed Load - 110kW. Comprising 62 Units, Lounge Areas, Dining Areas, Offices and Entry etc. |
Stage 3 :
1994 |
Installed Load - 85kW. Comprising 33 Units, 10 Wards, Lounge Areas, Dining Areas, Offices and Entry etc. |
Stage 4 :
1997 |
Installed Load - 25kW. Comprising 10 Units and a Chapel. |
Stage 5 :
2002 |
Installed Load - 75kW. Compromising 35 Wards, Corridors, Waiting Rooms and Nurses Stations. |
Stage 6 :
2002 |
Installed Load - 15kW. Compromising 2 Wards, Lobbies, Offices and Corridors. |
They were looking for a heating system that was totally hidden, but easily controllable.

Feedback from project leader:
As the only construction work being done was the installation of new walls and ceilings there was no alternative but to use Ceiling Heating to replace the old wall mounted Heat Banks.
The whole system was controlled using individual room air thermostats. Time clocks and Master Control switches were installed at the Nurses Stations.
Feedback from user:
The Director and Managers were very impressed with the level of comfort, controllability and fast warm up times. The lack of noise and draughts provides a clean, safe and healthy environment for the residents. Another benefit is there is virtually no regular maintenance required.
DEVI Conclusion:
Ceiling Heating was the only alternative for this project as the existing buildings were only being refurbished. Floor heating cables could not be installed.
Freezer Heating for Associated Baking
Frost Heave Protection
Frost Heave Protection was required for a Freezer being built into an existing building.
The design temperature was -25ºC and the freezer covered an area of 1,300m2.
The heating cables were installed on top of an existing floor and then covered with a 50mm slab.
150mm of "H" grade expanded polystyrene floor insulation was then laid over this slab. A 150mm concrete wear slab (25 MPA with F72 mesh) was then installed on top of the insulation.

devireg™ 330 |
DEVI Contact Person: David Mullins
Feedback from project leader:
A dual circuit heating system was installed with one circuit being connected now and the second circuit being installed as a back-up circuit.
The installation was controlled using 2 x devireg™ 330 thermostats. One devireg™ 330 was used to control the heating element, which is set at 10ºC and the second devireg™ 330 controls a warning light which is set at 5ºC.
Feedback from user:
"The installation of the heating cables was quick and easy, the construction work was able to proceed with a minimum of interruption and the only additional building cost was the installation of a 50mm slab to cover the heating cables."
DEVI Conclusion:
The fact that the Freezer was being built into an existing building meant that there was no other cost effective option. The only other alternative would have been to remove the existing floor in order to install a conventional forced air system.
Installation of heating cables in the base slab was the ideal way to provide frost heave protection. The cables also provide a system that is very effective and does not require any regular maintenance.
Soil Warming - MCG Cricket Pitch
Installation of Heating Cables in Cricket Pitches
In 1995 the existing Pyrotenax and ESWA heating cables installed in the cricket pitches at the Melbourne Cricket Ground were replaced using deviflex™ heating cables.
The areas heated were 3 of the 10 wickets and the area at each end of each wicket which is used for the bowlers' "run up".
The MCG is also used for Aussie Rules Football games during winter and as Melbourne is often very wet during the winter months the cricket pitches and bowlers' "run up" areas can very easily be damaged.

Feedback from project leader:
The areas to be heated comprised 3 wickets, each 22m x 2m, as well as the bowlers' "run up" at each end of the 10 wickets - total area of 30m x 1.5m x 2m.
The cables were installed at a depth of 100mm and at 100mm spacings.
Feedback from user:
"The installation of the cables has reduced the time required for the ground to recover from the damage caused during the Aussie rules Football season and the starting of the Cricket Season."
DEVI Conclusion:
Soil Warming is an ideal way to rejuvenate the grass between winter and summer sports.
