Upon exiting the expansion valve, the pressure lets up. Now a hot low-pressure gas once again, the cycle starts over. As a Boston resident, you’re all too familiar with wild temperature swings. Heat pumps do not generate heat, but rather move it from one place to another. Avoid using “Auto” mode, as this could cause the system to heat on a cool summer night or cool on a sunny winter afternoon. This depends on a variety of factors – such as the type of system and size of your home – but there’s a very good chance that a high-efficiency heat pump can heat your whole house. I have contacted a couple of HVAC dealers to quote for a heat pump to replace an old gas furnace only system (no AC and no solar). What this means is they use a refrigerant to absorb heat from the air inside your home and transport it outside. We intend to use the new heat pump for both cooling and heating. Like all other systems, make sure that you are paying attention to your filter. Consequently, it is recommended to only lower your set point by 3˚ – 5˚ when your system is in the unoccupied or night setting. If you buy one that’s too small, it won’t have the power to heat your entire home. First, adjust the switch on the bottom of the thermostat from HEAT to COOL—this will reverse the heat pump cycle. Air-source heat pumps work on a novel principle: instead of directly producing the heat that you need to keep warm through the winter, the heat pump will find heat energy in the outside air and bring it into your home, using refrigerant as the medium of heat exchange.. Air-Source Heat Pumps The air-source or air-to-air heat pump is the most popular type of heat pump today. Basically, that means your heat pump will act as an air conditioner when things get hot and a heater when it’s cold outside – making heat pumps one versatile product. All information is subject to change at any time without notice. Most Energy Efficient Heat Pumps for 2020 The most efficient heat pumps are chosen by homeowners in climates with extreme heat and for those that want their heating and air conditioning to be as ecofriendly as possible. They work on the principle of capturing heat and moving it from place to place, removing it from your home to provide cooling in the summer and bringing in heat from the outdoors for warming in the winter. In the summer time you could run your heat pump at 20 degrees and if you were to run it all night you could increase the temp to 22 degrees.Summer time humidity can get even the most hardy person down so set you heat pump to the dry mode and enjoy the cooler drier temperatures.The above is only a guideline for you to work. A heat pump is designed to pull the heat energy out of the outside air and use it to warm the inside of your home. Refrigerant enters the compressor (outdoor unit) of your heat pump system as a hot low-pressure gas and is compressed into a high-pressure gas. For this reason, this heat source is rather energy efficient. All Rights Reserved | Disclosure Policy. Fax: 302-629-3870.

When you call Peninsula, we will test connections, monitor airflow, and perform a number of other checks to make sure your system will last all summer long without any major problems. It does not constitute professional advice. 1. Tip: heat pumps are available in varying sizes. During the summer months, this means that heat is transferred from the indoors to … For example, if a heat pump has a COP of 3, this means the heat pump is capable of producing 3 units of heat for every watt of power used. Here’s the bottom line: heat pumps work most efficiently when they’re set to maintain a steady temperature in your home. If you rely on a heat pump to keep you warm over those long Boston winters, it makes sense to operate it as efficiently as possible. Today's heat pump can reduce your electricity use for heating by approximately 50% compared to electric resistance heating such as furnaces and baseboard heaters. The coolant picks up heat outside and comes through a pipe to the inside of the building, where it is compressed. Peninsula has been providing home services in Delaware and Maryland since 1935. Most heat pumps produce heat in two ways; one way is very efficient and the other is not. With a heat pump, if you bounce the thermostat up and down, then what happens is you force the electric-resistance heater to come on and that costs about twice as much or more to run than the heat-pump system. It works like this: During the winter, your heat pump follows the exact same steps in reverse, absorbing heat energy from the outside and moving it indoors. Call Boston Standard Company, The Company You Count On. © 2021 Peninsula. This doesn’t mean your heat pump should run all the time. While most efficient heat pump models can function efficiently in temperatures as low as -27 degrees celsius, it is a good idea to have a backup heating source for those unusually cold days where a heat pump loses its advantage in heating efficiency. Conversely, once the winter season rolls around, temperatures at or below freezing are commonplace. What Qualifies for the Residential Energy Tax Credit? You should be changing your filters every month to three months, depending on how often you’re using your system.

During the summer, heat pumps work just like regular air conditioners. High wall mounted heat pump Floor mounted heat pump For heating, direct the warm air down across the floor where it will rise up, warming the room.
