When it comes to the tankless water heater bosch offer quality and expertise. It is no coincidence that they are a European brand - gas has been a favored fuel for hot water needs for years throughout the continent.
Amongst the best in the world, a bosch tankless gas water heater is expected to last more than twenty years, which is longer than the scheduled life of any hot water tank (and something to include when you are calculating costs).
Perhaps the most famous part of the range is the bosch aquastar tankless water heater. These safety sealed units start out with highly portable units designed to offer enough hot water for a single need at a time. You could run a dishwasher from such a unit, but not take a shower at the same time (you could take the shower as soon as the dishwasher stops however, since these units will keeping on heating the water continuously if that is what you want).
If you have a bigger need, then there is a bosch tankless hot water heater to suit. The units mentioned above are really only for boosters in the home or for hot water out at the cabin. But there are slightly larger units that can comfortably meet the demands of a large household. And however big they get, they never reach the size of a household hot water tank!
