The U.S. water heater industry has been hit by a series of scandals, but there’s one industry sector that seems to be immune to such problems: the broken water heaters that were sold to customers in the United States and abroad.

The latest news comes from the National Association of Home Builders (NAHB), a trade association that represents home builders.

Nahb’s new annual survey found that nearly 40% of American homeowners have water heat in their home.

That’s up from 28% in 2012.

The survey found water heat is often the only water heating solution available for consumers who don’t have a choice of furnace or other heating method.

Nashville’s largest water heater maker, Ginkgo, reported its first-quarter sales of $5.8 billion, up 25% from a year earlier.

Its market share jumped to 31%.

The American Water Supply Association reported a 10% rise in its water heater sales for the first quarter of 2018.

The association said the increase was driven by the introduction of the Ginko G30 water heater and the availability of cheaper and more efficient water heat.

The average price of a water heater has dropped about 11% from its peak in 2010, according to the association.

A study by the University of Illinois’ Fuqua School of Business found that the number of homeowners who have purchased water heat has fallen from 8.6 million in 2016 to 6.3 million in 2018.

This is a big reason why there is still a big pool of unsold water heat for sale, the study found.

In 2018, there were 1.5 million residential water heat units in the U.s.

According to the Association, more than half of these units are being sold.

The NAHB report also showed a 13% increase in sales of water heat pumps in the third quarter of 2019, up from 9% in 2019.

It said this increase is mostly driven by demand from people who want more heat in homes they have and those who want to reduce their water usage.

According to the report, the majority of people are using their water heat to cook and cool their homes.
