Hybrid systems that run on propane and solar can be tailored to a project’s unique needs, providing lower first costs and reduced ongoing energy costs and emissions.

This may come as a shock (or not), but I’m not a huge sports fan. I root for my Alma Mater Michigan State (Go Green!), and that’s about it. Whereas my husband started planning his Super Bowl menu weeks in advance. Clearly, opposites attract!

As interest and incentives build to transition space heating and domestic water heating systems away from fossil fuels and toward electricity, a somewhat predictable but only marginally quantified problem is developing. Two words describe it: Peak demand.

Each year, Plumbing & Mechanical editors receive thousands of product releases from industry manufacturers. The 20 products highlighted here have earned the distinction of being PM’s Top Products of 2021 based on the number of page views on pmmag.com. Congratulations to those products on this year’s list.

As natural gas rates increase and the push for more sustainable energy sources intensifies, heat pump water heaters appear poised for massive growth. 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.

For years, environmental considerations and sustainability have influenced innovation in manufacturing, and in 2021, those factors became the driving force behind new product development.

The revised software, available online at no charge, adds the ability to compare projected costs and energy usage for all HVAC systems and hot water consumption in any building based on what is known before money is spent on selection of the HVAC and water heating systems, and almost all inputs may be adjusted once the design process begins. 

Electrification is often presented as a strategy for reducing carbon emissions, but the truth is, it’s not practical to rely on electricity alone because no single energy source can solve the long-term challenges we face.

On a military base in east-central Alaska — where the average winter temperature is 16° F with lows that fall well below minus 50° at times — dependable, low-maintenance winter heating systems are critical for the active-duty military families and Department of Defense civilians who live on the military post.

“I don’t think people care that I’m young, or female. They care about what I know.”
Those words, spoken by Baylie Frost, a virtual design and construction (VDC) lead at Harvey’s Plumbing & Heating in Bozeman, Montana, must be music to the ears of an industry that is seeking to attract more talented young people to its ranks.
