At Nissl Eichert we have changed our brand loyalty over the years to what we consider is the best value for money in the Australian market. As this technology changes and evolves we are always keeping our ears to the ground for the latest developments in efficiency and technological advancements. We would always recommend using any equipment until it is too expensive to repair or is made redundant due to advances in technology. With both those conditions in mind we would expect these boilers to last between 10 & 15 years. In that time the advancement of greener technologies will have changed what we have to offer you in the future.
