Turn Your Cottage Into a Cozy Second Home with an Energy Efficient 12 V Heater
Visiting an off-grid cottage year-round is one of the simple pleasures that is becoming more and more popular among nature lovers. When electricity is limited, a reliable and quick source of heat is needed, such as a diesel cottage heater. It has no exposed flame and the minimal exhaust gas is safely vented outside keeping the indoor air always fresh and odorless. Wallas cottage heaters produce dry heat and keep the interior fresh.
Energy-efficient diesel heater requires only about 0,2-04 amps, which is why a small solar panel is sufficient to recharge the battery. The fuel consumption is also so low, that a 33 liter (6 gal.) fuel tank will keep the heater running for almost six days. Wallas particularly recommends the Neste MY Renewable Diesel™, which is high-performing low carbon biofuel. 26 CC can be installed to the chimney or directly through the wall and the fuel tank can be stored underneath the cottage away from the eyes.
A seamless Nordic design is easy on the eye, both functional and beautiful, and comes in two color options; graphite gray and winter white. It is a stylish addition to the social spaces that are the heart of your cottage.
Fully enclosed laminar burning process ensures a quiet sound level and dries the indoor air.
Low temperature on unit for everyone’s safety.
Highly energy-efficient heater saves fuel and electricity.
GREENBOOST
Cleaner Burning
Updated software optimizes fuel consumption
Calibrated to burn renewable fossil free diesel (e.g. HVO)
Larger burner burns fuel slower resulting in ultra low NOX emissions
Extensively tested with Neste
Improved burner efficiency for more power
The Greenboost burner burns renewable fossil-free diesel cleanly and energy-efficiently.
Combustion air is pulled in from the outside and exhaust gas is safely expelled outside keeping the indoor air clean and odorless.
Fully enclosed laminar burning process ensures a quiet sound level and dries the indoor air.
The laminar free convection heat rises up from the top of the heater.
Brushless blower motors have a very long life-cycle, supporting reliably long service intervals.
Durable Finnish design and manufacturing keep your heater intact for years.
Low temperature on unit for everyone’s safety.
Thermostat controlled heater maintains a smooth temperature and keeps everyone comfortable.
Very low electricity and fuel consumption.
12 V battery is easy to recharge with a small solar panel or a wind generator.
Alternatively, the unit can be used in 110/230 V network with a 12 V converter.
The start button must be held down for 3 seconds to start the unit to avoid any accidental starts.

Technical values are measured in a reference measurement wall, which is constructed to represent a typical cottage installation. The figures allow for 10 % reserve – yours may vary.
Wallas diesel heaters are designed to run with standard road and boat diesel, as well as renewable fossil free diesel. Check with your distributor for further details on best options for your needs.
Accessories in black are included in the standard package. Accessories in blue are additional.
WALL INSTALLATION
For wall installation, the following is needed:
- 4004 Exhaust through-wall head
- 4030 30 liter tank
- 4880 Exhaust lead-through kit
- 4430 Remote Access system (if you’d like to control the heater remotely)
CHIMNEY INSTALLATION
For chimney installation, the following is needed:
- 4880 Exhaust through-wall kit
- 4030 30 liter tank
- 4430 Remote Access system (if you’d like to control the heater remotely)
FUNCTIONAL DIAGRAM
Wallas heaters have a fully enclosed burning process. A fan draws combustion air in and blows the exhaust gas into the outlet through a heat recovery unit. The enclosed process ensures exhaust gas will never contaminate the indoor air.
The fuel is drawn to the burner by a pump, which allows the placement of the fuel tank for instance under the cottage, where it can be easily re-filled.
The fuel in the burner is ignited by a glow plug. The fuel vaporizes and burns with a clean, blue flame. Once ignited, the burner is constructed to maintain the heat and the glow plug turns itself off.
All the above takes place fully automatically.
