We are very interested in getting a tankless water heater. We have been investigating the Bosch AquaStar 125X NG. It has an electric start and uses Natural Gas. We had a furnace/water heater professional out here to give us an estimate on installing it for us and he claims all the contractors out here do not recommend them at all... Is there any one out there that has put them in their homes? and how do they like them? Thanks so much!!
