Air flow Heat pump systems require 20-30% higher air flow rates than conventional forced air furnaces. This is to compensate for lower temperatures of the heated air. In many cases, existing ductwork can handle the increased flow rates but it is something to get your installer to check when preparing a quote. NRCan has a guide… Continue reading
Ducted Homes with existing forced air systems can use the existing ductwork with their heat pumps. An air handler is included in the installed heat pumps systems. Since heat pump systems require 20-30% higher air flow rates than conventional forced air furnaces, it is important to have the installer inspect the existing ductwork. For more… Continue reading
Ground source heat pumps Ground source heat pumps (GSHP) release heat into and absorb heat from the ground. They require underground piping: in horizontal trenches below the frost line or in deep, vertically bored holes. They can meet a home’s heating and cooling needs through the entire year and can also be used to help… Continue reading
Upgrading your home’s space and water heating systems to heat pumps may be the single most important step you can take to reduce your home’s carbon footprint and help avert catastrophic climate change. Buildings are the third largest source of greenhouse gas emissions in Canada after the oil and gas industry and transportation. The burning… Continue reading
Besides being the cool kid on the block, heat pumps have many benefits. Can provide all of your home’s heating and cooling, or hot water needs; Are more energy efficient because they move heat rather than generating heat; Can replace a furnace and an air conditioning system or a conventional water heater; Can make your… Continue reading
Heat pumps use the mechanical refrigeration cycle to move heat from one place to another. Just as your fridge moves heat from inside the fridge to the kitchen, so too does your heat pump move heat from relatively cool places to warmer ones. A heat pump is even better than a fridge though: it is… Continue reading
Heat pumps are mechanical systems that use electricity to move heat from one place to another. They are very efficient, using far less energy to heat a space than it would take to generate the same heat by burning a fuel. And they can move heat in either direction, to cool a space in summer and to heat it in the winter.
