Kelalan Highlands Microsolar Heater Project, Sarawak, Malaysia.
M80VTHE Water Heater being installed Mar 2006 at Apple Lodge, Buduk Nur
Village, at an elevation of 950m. The nighttime ambient air temperatures
drop down to 14C but the Microsolar is still able to produce hot water
at 80C to 98C without any electricity backup.
The existing microhydro electricity project in the Ba Kelalan valley is
not strong enough to power conventional electric water heaters, and so
solar thermal energy remains the only solution. The Microsolar is the
only solar water heater that is proven to work efficiently in the overcast
cloudy and rainy climate of the Ba Kelalan Highlands of Sarawak. The Microsolar
Ba Kelalan Project was officially opened 31 March 2006 by his Excellency
TYT The Governor of Sarawak.
Kelalan is surrounded by mountains, at the starting point of the 3 day
trek up Gunung Murud 2423m and the new Ulong Tau National Park. It is
reachable by a daily (RM60.00) 5 hour 4WD journey off road from Lawas,
Sarawak or by MAS Twin Otter (RM60.00) twice weekly from Lawas. It is
in the middle of the picturesque agricultural Lun Bawang high country,
with rice paddies and water buffaloes, next to apple orchards, durians,
and fish ponds. Everybody is genuinely friendly and a walk thru the whole
village sometimes takes ages stopping to chat with the neighbours. (You
would not guess from their friendly gentle nature that the Lun Bawang
are descended from one of the most feared head hunter tribes of Sarawak.)
Nights are full of stars, cold and quiet once the generators are switched
off, only the sounds of neighbours walking in the dark with torchlights
and chatting. The sound of cocks crowing and flapping their wings, dogs
barking in the village lane, the drone of the last motorbikes laden with
supplies brought up by 4WD from Lawas heading to the Kalimantan border
through the jungle trails and quiet again.
In the hotel insects fly against the energy saving bulbs (microhydro electricity)
and carpet the floor.
And so if you find yourself in that part of Sarawak, and in need of a
(very) hot luxury shower, check out the Microsolar at the Apple Lodge,
Ba Kelalan. If you are not lucky enough to be in Lun Bawang country, and
you want a very hot solar heater that will work in cloudy weather totally
without electricity, even in the Klang Valley, see below.

comparison, other brands of solar heating conventional flat panels are
mainly Single Valve, with bottlenecked single channel energy movement
between the collector panel and the heat storage tank. And whilst solar
thermosyphon convection is directly up and down, never horizontal, the
hot water pipe manifold at top of conventional flat solar heater panels
is unfortunately horizontal, so hot water collected is impeded from rising
freely into the storage tank, whereas Microsolar is Coaxial Multivalve
and the collector tubes are vertically aligned and enter and leave the
storage tank thru multiple channels, freeing up the solar thermal energy
to rise into the insulated tank. High technology that works even in inclement
weather. One would not want invest in an expensive single valved solar
collector panel that will not work in cloudy weather.
Excellency TYT the Governor of Sarawak Tun
Datuk Patinggi Abang Haji Mohammed Salahuddin and
his wife Toh Puan tests the temperature of the Microsolar hot water
at the opening ceremony of the Microsolar Ba Kelalan Project. This
stand pipe directly below the Microsolar provides pasteurized potable
hot water for the use of the villagers, in an area where there are
no government water treatment plants. At left is the Resident of
