Learn more about heat pumps, an exciting technology that lets you heat and cool your home sustainably instead of HVAC.
What different types of heat pumps are there? There are different types of heat pumps: air-source and ground-source. Heat pumps can also be paired with fossil fuel gas furnaces; these systems are often referred to as hybrid heat pumps. How does an air-source heat pump work? An air-sourc...
which work best with large-scale stationary power generators. Fuel cells of this kind operate at very high temperatures (between 700 and 1,000 degrees Celsius). This high temperature makes reliability a problem because parts of the fuel cell can break down after cycling on and off repeatedly. ...
HOW DO HEAT PUMPS WORK FREQUENTLY ASKED QUESTIONS The annual energy consumption of a heat pump typically falls within the range of 6,176 to 10,244 kilowatt hours (kWh), influenced by various factors.1Factors such as the unit's size, efficiency rating (e.g., SEER2 and HSPF2), and ...
A submersible pump at a petrol station is an efficient way of delivering fuel. It is designed to be submerged in any liquid and uses less energy than conventional pumps. A submersible pump also uses less energy, which benefits the business. Another benefit is that the gas inside the pipe do...

The U.S. Post Office suspended the use of pneumatic mail transport, saying that it used too much fuel to power the air compressors that they needed. After the war, the service eventually was restored, but only in New York and Boston. Private companies that would have built new systems ...
Most service stations do the job using one of two types of pump -- a submersible pump or a suction pump: A submersible pump, as its name implies, is submerged below the surface of the liquid, where it uses a propellerlike device called an impeller to move the fuel upward. Slanted blade...
In winter, heat pumps work exactly the same way. But this time they pick up heat from outside and move it into your home. Of course, it’s sometimes freezing outside when you want to use your heater. But the air doesn’t need to be warm— it just needs to be warmer than the re...
Maintenance for a hydronic system is minimal — the boiler needs an annual check-up, but most modern pumps use water to lubricate the parts and are low-maintenance. However, if your system breaks, you'll need to hire a professional, because fixing it can be complicated. It's also expensiv...
