Webasto
have a diesel powered DualTop compact unit which
combines domestic hot water with interior cabin heating
for motorhomes. Wesbasto have the DualTop models
RHA 101, 102 & 103 that produce heating power ranging
from 0.2 kW – 9.2 kW depending on the model and they are
all fueled directly from the vehicle’s fuel tank. The
RHA 102 & 103 models feature digital control.
The
DualTop hot water heater and interior heating unit can
be installed underfloor thereby freeing up internal
space within the motorhome.
Also for the motorhome market Eberspacher have
produced a miniature diesel fueled water heating system
which can be installed underfloor or in the engine
compartment. The Hydron D4W System provides a
heating system with an automatic sensing and temperature
control for the vehicle interior and sufficient stored
hot water for your domestic use. Diesel fuel to operate
the system is taken direct from the vehicle’s fuel
tank. The 10 litre hot water storage tank features a
thermostatic mixer valve that automatically blends hot
and cold water thereby increasing the amount of
available hot water.
For heating the interior and hot water of a Class A
motorhome or Luxury Coach there is the Oasis Modular
Heating System which is an RV diesel ‘hydronic
system’. The system has two components, the first is
the heating module which is available in two models CH35
& CH50 which have 35,000 BTU/ph and 50,000 BTU/.ph
respectively.
See what is a BTU. The Oasis Distribution Model is
the second component and this comprises an engine
interface heat exchanger, a domestic water heat
exchanger with an anti-scald valve together with
circulation pumps and a winter/summer solenoid.
International Thermal Research define their ‘hydronic
system’as ‘The circulation of hot water to provide
heat is known as a
“Hydronic” System.
It is a closed system continually circulating the same
coolant. It begins with a furnace or boiler, usually
fueled by diesel, or electric elements that heat the
coolant to 180 degrees. A water pump circulates the hot
coolant through a domestic water heater and then to the
various fan units located throughout the interior of the
motor home or yacht for example. An engine coolant loop
can also be added to preheat the engine or use the
engine's wasted heat’.
Gas Free Cooking for Motorhomes
When not connected to mains power most
motorhomes rely on LPG gas for cooking but now
Webasto have introduced a Webasto Diesel
Cooker X100 for gas free cooking. For the
heat source a diesel burner is integrated into
the cooker which heats a Ceran ® glass top
cooking surface suitable for two small
saucepans. The exhaust is vented to the outside
of the motorhome. The manufacturer states it
has a low current and fuel consumption with high
cooking power up to 1800 watts.
Diesel fueled ceramic cooktops are also produced by
Wallas mainly for marine application but some RV
owners have adopted their use and installed them in
motorhomes. The fuel for these diesel operated cooktops
can be taken from the motorhome’s diesel tank.
