HEAT PUMPS

Heat pumps are heating and cooling appliances that are installed on the exterior of your home. They are like air conditioners but more of them as they warm and cool your house. In cold seasons, heat pumps draw warmth from the outdoor air, transferring it inside, and the reverse applies in warmer months. Heat pumps run on electricity and use a refrigerant to distribute heat.

HEAT PUMP FAQS

  • What Size Heat Pump Do I Need?

    For every one sq ft, you will need a 30 BTU unit. You will need an HVAC expert to determine the right size you need. All experts calculate the needed size and refer the BTU units to the HVAC sizing book.
    Still, there are other determinants in play, such as the heating appliances in your home, the local climate, and how the home is insulated. A poorly insulated home will need more heat, and hence a larger heating unit. Also, colder regions will need larger units to suit the need for higher heating.
    However, you can do the calculations yourself. Assuming you have a 2,500 sq ft home in need of a heat pump.
    For instance, to tell the BTU you need, you can use the 30BTU per sq ft to estimate what will be needed by 2500sq ft. let's say, if 1sq ft calls for 30BTU, then what will 2,500 sq ft need. The multiplication should give you 75,000 BTUs. When converted to tons based on the g heat pump sizing chart, it gives you 6.25 tons of heat. In short, a 75,000BTUs will be needed for a 25000sq ft property. And the larger the home, the larger the unit needed.

  • What Is the Efficiency of A Heat Pump?

    Heaters running on electricity and toasters are one hundred percent efficient, meaning they produce as much heat as they absorb. Heat pumps, however, have efficiencies of up to 300 %. They do not generate heat. Instead, they absorb them from the outdoor air or ground and distribute them to colder regions indoors.
    Heat pumps, therefore, use less electricity, yet they produce heat effectively. For instance, a ground source heat pump can consume 1kw electricity and deliver about 4kw of heat. Since heat energy is freely available, they are more efficient than other heating units. Using them means you get to reduce heating bills by almost two-thirds.
    Further heat pump efficiencies are dependent on the price of fossil fuels vs. that of electricity. The cost of fossil fuel is high and comes with the hazards of hydrocarbons. Again, if you are using pool heat pumps, you have an additional advantage. When your house is cooling, your pool gets heat in return.
    It saves energy that is used for heating the pool independently, hence reducing energy bills. Again, you won't install a heat pump in a house that's not well insulated. Insulation means less heat exchange between the exterior and interior air, which minimizes any chances of heat wastage.

  • How to Install A Heat Pump?

    Installation of heat pumps will vary depending on whether they are installed outdoors or indoors. Also, if you are installing a ductless system, the location should be unobstructed. For indoor installation, you will need a mounting plate, a driller, and screws. If your system is ducted, make sure you have access to the interior ductwork. If it is inaccessible, you will have to install new ones.
    The second step is to create an access point on the wall of the basement or attic to link the indoor unit and the outdoor condenser.
    Drilling through the piping lines should get the job done. This should allow passage for refrigerant, electrical, and condensate drain lines. The refrigerant and condensate lines are then connected to the indoor unit. The lines installed will allow the latter to circulate in the outdoor and the indoor condenser.
    The next step should involve you connecting the wiring to an electricity supply. All the lines installed should be insulated and a drain installed on the outside for condensation.
    Lastly, you have to install temperature sensors, which help in adjusting heat requirements. To make monitoring easy, your heat pump might also feature remote heat sensors that can be accessed through phones or tablets.

  • What Are the Advantages and Disadvantages of Heat Pumps?

    Pros
    • They are powered by air, ground, and water, which are non-harmful energy sources, unlike furnaces that run on fossil fuels that leave behind a carbon footprint.
    • They are super-efficient compared to heaters and toasters. they don't generate heat, but they use free heat from the air, water, and the ground, and this gives them a spike of 300% efficiency
    • If you are using natural gas heaters and furnaces, shifting to heat pumps means you get to reduce your energy bill. Besides, it makes you eligible for rebates from the federal government and the BC Hydro.
     
    Cons 
    Tough to Put in
    A heat pump is somewhat hard to install. Research needs to be done to comprehend heat movement, resident geology, and heat demands. Besides, most installations must be done by a pro.
    Cannot function well in cold weather
     
    Heat pumps fail to run efficiently in cold regions, and the system may entirely fail to work. You have to use an upgraded version that has inverter technology to come around this. However, that means that you will have to spend further. And if it can't be done, then your system becomes completely redundant in colder seasons

  • How Much Does A Heat Pump Cost?

    The costs of heat pumps range from $4,110 to $7,240, relying on type, setup charges, and the specific architecture of your property. But the average price is normally $5,680, which again depends on your location, present HVAC system, and the manufacturer. 
    The price of heat pumps is heavily influenced by the size and construction of your property. An expert will assess your structure's load capacity and the heat pump size that will be needed. Also, Windows, thick walls and local geology play an important part when selecting a heat pump.
    Therefore, if a residential space has floor-to-ceiling arched windows, then the selected heat pump will require an additional kick in colder months.
    Selecting the appropriate heat pump size for your house guarantees that it will function effectively and sustainably as it matures. Here are some of the heat pump rates;
    • The cost of a 2-ton heat pump is between $3,500 and $5,500.
    • The cost of a 2.5-Ton Heat Pump ranges from $3,700–$5,800
    • The Cost of a 3-Ton Heat Pump starts from $3,900 to about $6,200 
    • The cost of a 4-ton heat pump ranges between $4,000 and $7,300.
    • The cost of a 5-ton heat pump is between $4,500 and $8,800.

  • What Are the Different Types of Heat Pumps?

    The two most used types of heat pumps are the geothermal heat pump and the air-to-air heat pump. For instance, the geothermal heat pump is considered the most efficient, and it transfers heat between you and the ground or the nearby water source. However, they cost much when it comes to installation. Their advantage is that their operational costs are low and leverage the constant temperatures of the ground; they reduce energy consumption by up to 60 %, control humidity, and are steady.
    On the other hand, the air source heat pump is the most common type of heat pump, and it uses outdoor air as a heat source and a sink. They use a vapor-compression refrigeration mechanism and an external heat exchanger with a fan to cool the house in the cooling cycle. An air-to-air heat pump is a less complicated machine that delivers warm or cold air straight to indoor areas. 
    An Air-to-water heat pump uses radiators or radiant floor heaters to warm an entire home and is frequently used to deliver household hot water. If properly designed, an ASHP may provide a complete heating system and a domestic source for hot water by 176 °F.

  • How Does A Heat Pump Work?

    A heat pump while operating functions as an air conditioner. With that said, warm air within your house flows in the conditioning system components. Heat is then drawn from the air by a refrigerant in the cooling coil. The refrigerant containing warm air is then compressed repeatedly to create more pressure. It flows into the condenser coil from the compression chamber, where it releases heat in the outdoor air.
    However, this is how an air conditioner works. A heat pump will also work in the same manner when in cooling mode. But what states the difference is that it can work in a reverse manner where the above process is inverted to provide heat internally. If it's a geothermal heat pump, it will suck in water from a source, and the refrigerant will absorb the heat in the same manner. 
    Again, a heat pump will absorb heat in cold air or cold water, pressurize it to increase heat intensity, and then pump into colder spaces. So regardless of the weather patterns, a high-quality heat pump can run even in below zero temperatures. Heat pumps that use ground also leverage the constant temperatures of the ground surface when absorbing heat, and they also use the ground as a sink.
     

  • What Is A Heat Pump?

    Heat pumps are HVAC devices that integrate heating, ventilation, and air conditioning capabilities. They distribute heat energy absorbed from the air, ground, or water bodies to colder regions when it's cold, and the reverse applies when temperatures spike.
    They move heat in the opposite direction, irrespective of thermodynamic laws, as they absorb heat in cold regions and release it to warmer spaces. The heat pump's sole function is to heat the radiators, underfloor heating system, and heat convectors. 
    Still, they come in handy when heating water in your pool or tanks. Nearly all heat pumps have climate control functionality and can switch from cooling to heating depending on temperature changes. It functions as a conventional air conditioner, but it can work in reverse mode.
    They can be installed outdoors on your home's wall or in the attic or basement. You have probably seen box-like equipment outside some buildings. Heat pumps use less electricity to run as the heat distributed is absorbed from the surroundings. 
    Also, they do not run-on fossil fuels that leave a carbon footprint on the environment. In terms of effectiveness, heat pumps are installed based on the size of the property. Smaller heat pumps will do just fine in small-sized properties.
