STUNNING - The Walltherm Log Boiler

Walltherm Zebru Log Gasification Stove The Walltherm is a simple and elegant stove with a build quality second to none. Its secret lies in using log-gasification reverse-flame combustion technology, but adapted to a domestic stove.

walltherm zebru zebru with log store zebru-insert

Here’s how it works… The stove has two combustion chambers. The fire is lit in the upper chamber and produces wood gas while burning. This hot gas is pulled down through combustion jets, where it is mixed with a secondary air supply. In the lower chamber, the gas ignites and creates a second flame that generates up to 1000ºC. This burns cleanly and efficiently. The hot exhaust gases then run up through the heat exchanger, which is designed to absorb the highest amount of heat possible. Impressively, by the time the gases reach the chimney, the temperature will be less than 130°C and the house will be warm, the domestic water hot, and the thermal store heating up nicely. As well as achieving record-breaking efficiency, and a low level of emissions, the Walltherm’s double windows provide a visual treat like no other stove. The glowing log fire can be viewed through a large double-glazed panel in the main door, while the lower window shows the gasification chamber, where spectacular super-hot flames pour down through the fire-bed slot and curl round to enter the heat exchanger tubes at the rear.

  • 93% efficiency

Energy Store Thermal Store A thermal store also acts as a buffer, supplying an instant source of heat whilst your boiler biomass boiler comes up to temperature, and can also provide an extra source of heat for periods of high demand which may allow you to provide all the heat that a property needs from a boiler which would otherwise be too small. A thermal store is a must for most log burner, however the pellet boiler range is fine to be integrated into any existing system as they run in a very controllable fashion similar to a typical gas or oil boiler, unlike log burners which are batch burners and comparatively less controllable.
