The ETA range of biomass boilers is broad and all encompassing, domestic solutions through to large commercial 350kW boilers and covering Pellet, Log and Wood Chip fuels.


MetalERG range of boilers


MetalERG Straw Boilers up to 600kW

MetalERG has manufactured straw-fired boilers since 1993. Suitable for farmers, rural businesses and local communities who are looking for cost-effective heating systems. Straw-fired biomass boilers offer significant advantages as straw is thermally efficient, and cheaper than all fossil fuels and other forms of biomass. It is readily available as a by-product of agriculture and requires minimal processing to be used as a fuel.

With the MetalERG range of boilers, the EkoPal can provide outputs from 600kW and its a a great solution for the larger sized installations across sectors from country houses, drying facilities and pig units. The boiler sits outside and can be provided to work alongside existing Biomass installations, e.g. combined with 205 ETA Woodchip or comes in a pre packaged solution where the 25,000Litre accumulator and boiler site alongside each other to  typically up to 1MW is size. While these boilers have been designed for burning straw they can also be fired with wood chips, willow energy, textile waste, sawdust and other biomass.
