40 EA COTTAGE | Water Heater

Wallas 40 EA is a water heating system for off-grid cottages that can be used solely as a hot water heater for domestic water or it can also power up underfloor heating and radiators. Underfloor water heating system is an excellent alternative to air heating as it disperses dry heat evenly in the space and provides an added luxury of having comfortably warm floors to walk on. When heat transfer fluid is run underneath the flooring, there is no air blowing in the space, which can also be a relief to some, if allergies are a concern.

Energy-efficient Wallas diesel cottage heater requires only about 0,2-04 amps, which is why a small solar panel is sufficient to recharge the 12 V battery. 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.

The modern design of Wallas 40 EA is both functional and beautiful, and comes in two color options: graphite gray and winter white, which match any decor. The unit and fuel tank can also be installed in a utility room away from the eyes. 40 EA cottage heater is widely used in the Nordic Countries and it has been found to be an excellent heating option for cool summer evenings as well as freezing cold winter nights. You can transform your off-grid cottage into a perfect resting spot, where you can relax with family and friends year-round.
