Heat pumps heat air to a lower (but still hot) temperature vs a gas furnace, so they need to move more air to keep your home warm. If your home has small ducts, more common in cold climates, you can either upgrade them or install aduct-less heat pump. Replacing ductwork is a big ...
You input the size of your heat pump (in tons), SEER rating for cooling mode or HSPF rating for heating mode, and the calculator will tell you how much electricity your heat pump use (kWh per hour, kWh per day, and kWh per month). Additionally, the heat pump running cost calculators...
One type of open-loop system is sometimes referred to as a pump-and-dump system. That pretty much tells you how it operates. You pump water from the ground or a pond, run it through the heat exchanger, and dump it onto the surface or into a storm sewer. That type is widely illegal...

In this study, a HHP system that consists of an air-source heat pump (ASHP) and a condensing-type gas boiler (GB) for a two-story single-family house was calculated and validated. The results from three different calculation methods were obtained: the heat pump manufacturer’s calculator, ...

The input data for natural gas, air volume, and water vapor required for the stack model were determined using the calculator model of Aspen Plus TM. Assuming that the cells in the stack are connected in parallel, the voltage of each battery is the same. The current of the fuel cell stac...
Similarly, a water consumption calculator was launched in the UK for households, through a survey [13]. Based on statistical algorithms and input from over 100,000 users, on questions about usage patterns, a large dataset for domestic water usage was formulated. The ultimate objective of is ...
