Tankless heaters are like solar water heaters in Arizona several years ago. While there were incentives, everyone and his brother was making and installing them. Then the bust came and none of these companies were around except for the main manufacturers. There are a few mainline tankless companies, but there were, and are, Italian and Japanese brands for example, that had a big push for sales and then the companies went out of business and there are no parts or service available for them. Even with the good companies, service can be a problem if the technician is not familiar with them.
