Employers continue to struggle to bring in new workers and keep existing ones. Job openings far outnumber individuals looking for work — in March, there were 11.5 million jobs to fill, and not enough workers to fill them, according to data from the U.S. Bureau of Labor Statistics Job Openings and Labor Turnover Summary.

States such as California and Massachusetts already have regulations prohibiting or disincentivizing gas water heaters in new construction, and New York City recently enacted similar restrictions for new construction. So, are heat pump water heaters the future of the water heating market? Maybe or maybe not — but some industry experts certainly think so.

Boiler Boilers should be inspected and serviced by a professional installer or technician at least once a year. The intense environment inside a high-efficiency boiler should be monitored and serviced to maintain peak efficiency.
