Electrek spoke with Heidi Gehring, associate director, cooling product marketing at Carrier HVAC, about the five essential things to know about this energy-efficient, cost-effective way to heat and cool a home.

Electrek: What’s a heat pump and how does it work?

Heidi Gehring: A heat pump is often mistaken for an air conditioner at first glance. What makes it different from an air conditioner is that it can both heat and cool your home using electricity and refrigerant.

In cooler months, heat is pulled from the outdoor air and transferred indoors; in warmer months, the system pulls heat out of the indoor air. Heat pumps have both an indoor and outdoor component. Each unit contains a fan and coil that operates either as a condenser (in cooling mode) or an evaporator (in heating mode). The fan moves the air across the coil and throughout the ducts in the home.

Electrek: Do heat pumps save you money, and what kinds of cost savings can be expected?

Heidi Gehring: Because heat pumps are more energy efficient, they can save you money on your heating and cooling bills. Your savings will vary based on the model you select.

Heat pumps are rated by their Heating Seasonal Performance Factor (HSPF2) – which is a measure of a heat pump’s overall energy efficiency during the heating season – their Seasonal Energy Efficiency Ratio (SEER2), and their Energy Efficiency Ratio (EER2). The higher the rating, the more energy-efficient the system.

Additionally, the US government’s Inflation Reduction Act of 2022 includes incentives for the installation of high-efficiency home heating and cooling products, including up to a $2,000 tax credit for high-efficiency heat pumps and up to 30% for geothermal heat pump systems placed in service between 2022 and 2032. Look into local and state programs, too, as many utilities and local governments offer heat pump rebates.

Electrek: Why is a heat pump better for the environment?

Heidi Gehring: Heat pumps rely on electricity rather than fossil fuels, making them a much greener choice. Improvements in technology in recent years also mean that heat pumps are more efficient than ever, requiring less electricity than older heaters, furnaces, and air conditioners.

Geothermal heat pumps are also available – they pull energy directly from the earth to heat or cool your home and can result in up to 70% savings on your energy bill.

Electrek: What features should you consider when comparing different models?

Heidi Gehring: Heat pumps vary in the number of stages or speeds they offer. Different speeds or stages can affect your comfort and the consistency of indoor temperature. Humidity plays a major role but is often overlooked. Two-stage and variable-speed offer better control because they operate for a longer period of time at lower speeds and use less energy. These pull more humidity out of the air than models with a single-stage compressor.

Variable-speed and two-stage models are generally quieter than single-stage models, and because they run longer, that means the air is run through the filter more, so it has less chance of becoming stagnant.

Electrek: When is the best time of year to install a heat pump?

Heidi Gehring: Usually in the spring or fall. During the coldest winter months and hottest summer months, demand for systems and technicians increases, so you may experience longer wait times and higher prices. Make sure you hire a professional. HVAC systems of any kind require expert knowledge for installation and are not a good DIY project.

If you’re switching from a traditional HVAC system to a heat pump, you may also need electrical upgrades. A professional HVAC installer can help you with that as well.

The first US-built offshore wind substation is sailing to New York

The first US-built offshore wind substation is sailing to New York

The first US-built offshore wind substation is complete and headed to South Fork Wind – a major milestone for the US offshore wind industry.

Offshore substations collect and stabilize power that the wind turbines generate, preparing it for transmission to shore. South Fork Wind’s 1,500-ton, 60-foot-tall substation was designed and engineered in Kansas, and built near Corpus Christi by Kiewit Offshore Services, the largest offshore fabricator in the US.

The first US-built offshore wind substation left Kiewit’s factory on a ship late last week. It’s going to cross the Gulf of Mexico and then sail up the East Coast for installation off Long Island in a few weeks.

David Hardy, group EVP and CEO Americas at Ørsted, said:

The completion of South Fork Wind’s offshore wind substation is yet another first for this groundbreaking project and moves us one step closer to the project’s first ‘steel in the water.’

South Fork, which is being jointly developed by Danish wind giant Ørsted and energy provider Eversource, is expected to be operational by 2023, when it will become the first completed utility-scale offshore wind farm in US federal waters.

Cable laying is currently under way, and the installation of monopile foundations will begin in coming weeks.

The 132 megawatt (MW), 12-turbine project will produce enough clean energy to power 70,000 homes in New York.

If you’re considering going solar, it’s always a good idea to get quotes from a few installers.

ZParq completes $2.7M seed round to bring ultracompact electric marine motors to market

ZParq completes .7M seed round to bring ultracompact electric marine motors to market

Swedish marine propulsion startup ZParq announced it has successfully completed a seed round led by cleantech investors, totaling 2.5 million euros ($2.68M). With the fresh funding, ZParq looks to bring its compact electric marine motors, powertrains, and other adjacent technologies to market to help decarbonize the segment.

ZParq is a young startup founded in Sweden in 2020, which, according to the company, was founded to challenge the limits of marine propulsion by providing the most compact and scalable systems for propeller-driven watercraft. Furthermore, the startup is striving to deliver products that are designed to be sustainable over the entire value chain. Per the company site:

Our founding team covers the span of electromechanical design, hydrodynamics, electronics and product design. We’ve been developing our technology to fill the gap where compact submersible electric propulsion systems are needed for high performance applications.

As you’ll see below, ZParq has already developed and sleek and compact portfolio of marine technologies, including electric motors, battery packs, inverters, levers, and even a steering joystick. Early on, ZParq joined the portfolio of EIT InnoEnergy – the largest impact cleantech investor in Europe, who was the startup’s first institutional investor.

Now, EIT InnoEnergy, along with a couple of other capital venture funds, have opened up their checkbooks to help get ZParq’s electric marine motors out to market and beyond.

ZParq’s electric marine motors are sustainable end-to-end

The startup recently shared details of its successful seed round coled by Santander (via the Santander InnoEnergy Climate Fund) and Almi Invest GreenTech. EIT InnoEnergy also participated once again.

Each of these funds is focused around investments in early-stage companies developing new technologies to support a circular economy and combat climate change. Clearly, they see potential in ZParq – which is touting all-electric marine motors that are significantly smaller and more efficient compared to everything else on the current market.

ZParq states the motor’s light design reduces raw material and CO₂ footprint by more than 50% in the production phase, and the circular design approach of its products helps reduce their environmental impact and climate footprint throughout their entire life cycle. ZParq CEO Jonas Genchel spoke to the successful seed round and the venture capitalists that have shown their support:

We are very happy to get Santander and Almi Invest GreenTech as new investors, they will provide us with the support required to finalize development of our first products and enable shipment to our customers already this year. Our scalable and modular technology has generated an overwhelming interest from boat manufacturers and ship builders globally, and we have customers within the complete range from small leisure boats to commercial vessels waiting for our powertrains. The company is currently in pilot phase with several OEMs and boat builders who are testing its 10kW and 50kW motors. It aims to have several units operating in water by this summer

It appears ZParq already has plenty of exciting electric marine technology in the works, including more powerful motors, so we will be sure to track its progress as these products approach market launch. A fresh 2.5 million euros should certainly help it continue to innovate and hopefully find success. More to come.
