Wallas 22DT (single outlet kit)

This kit is a 2.2kw diesel fired hot air heater suitable for running a dry heating system (ducting and vents). This marine kit is supplied with copper fuel piping and appropriate connections and fittings that should satisfy the BSS regulations for fitment onto an inland boat (if fitted correctly), however it is ofcourse still perfectly suitable for fitment into an offshore boat aswell.

Please look at the information below to find out more, if you would like any help or further information then please feel free to give us a call.

Kit contents

Wallas 22DT diesel heater (and mounting bracket)

Please note: We can put together alternative kits should you need something different for your particular installation.

Why buy a Wallas?

There are three main reasons to buy a Wallas heating system over its competitors:

Quality and Reliability - The laminar burn process is extremely tolerant of the somewhat dubious quality fuels we get on the waterways, and as a true marine heater its non-ferrous construction and superior build quality is the foundation for years of faithful service.
Efficiency - The 12v consumption of the DT range is extremely low, and the fuel consumption is fantastic, heating your boat need'nt cost a fortune!
Quiet Running - The laminar burn process is alot quieter than other diesel heating products, you dont get that "jet engine" noise that annoys you and any neighbouring boats.

Control Panel Functionality

Control panel Operation
Smooth, intelligent PI thermo control option	Wallas PI-thermo control adjusts the heater to heat up fast and after that it keeps the effect of the heater even to assure smooth cabin temperature without any changing blowing noises.

Manual control option	The heater can alternatively be controlled by simple rheostat in manual control mode.
Two step air boost	To enhance cabin drying, the main blower speed can be elevated independent of the heating power setting using the air boost function.
Fresh air ventilation	During warm days it is handy to blow fresh air into the cabin without heating, using the Ventilation feature.
Sun switch	The Sun Switch feature reduces energy use by automatically stopping the heater when weather conditions elevate cabin temperature. The Sun Switch will shut the heater down if cabin temperatures dwell above 3 degrees C above the thermostatic set point for more than 30 minutes.
Accidental start stop feature	Accidental heater starts or stops are prevented by a two second start/stop button delay

Please note that the control panel is supplied with a bezel so it can either be flush or surface mounted.

Fitment Considerations

The Wallas 22DT is a room sealed product. It draws combustion air down the outer skin of the exhaust tubing (from the skin fitting), then after the combustion process expels it out through the inner skin of the exhaust tubing (out the skin fitting). This means that it is not using an air form within the boat.
The combustion air inlet / exhaust outlet can be seen on the top side of the heater in the centre.
The circulation air (that is heated and blown into the cabin) is drawn into the two large holes on one end of the heater, over the heat exchanger and then blown out the two large holes at the other end of the heater. The Wallas is deliberatley designed so that it can be mounted either way round, therefore you can position the heater to face the correct way, rather than have to pass ducting 180 degrees back on itself.
It is also worth noting that in order to preserve the heat output from the heater you may want to insulate longer lengths of ducting so that the air doesnt lose some of its heat on the way to the outlet.
If you do not wish the circulation air to be drawn from the space in which the heater is mounted, we can provide an "inlet kit". This is a length of ducting and a stainless steel grill for bulkhead mounting. Please note that you would need two of these kits if you wish the heater to draw circulation air from a completely separate space to where it is mounted.
When installing a Wallas 22DT, 30DT or 40DT you will need to run ducting around the boat / cabin to position outlets and hence distribute the heat.

Inland Waterways considerations

Inland waterways considerations

The most popular inland boats for these units to be installed in are river Cruisers, this leads to a number of things needing to be considered:

Wallas heaters use a top mounted dip pipe fuel take off (when drawing from the main tank). Therefore access to the top of the tank is neccessary (side access is possible, please ask for details),
All fuel pipe to pass BSS regulations will need to be copper or ISO7840 rated rubber,
Exhaust positioning, fuel supply and 12v supply will all be subject to BSS regulations,
One of our (Ely Boat Chandlers) members of staff is an independant Boat Safety Scheme examiner and would be happy advise a customer regarding BSS regulations relating to fitment of a Wallas 22DT (or alternative model). Fitment of a marine diesel heater sounds problematic, but if you follow the installation manual provided and take account of BSS regulations it is pretty simplistic compared to many other DIY installations carried out by boatowners
