Choosing a Heat Pump Air Conditioner

When choosing a heat pump, there are a number of factors to consider. This article should leave you better informed on choosing a heat pump.

Location, location, location…

Where you want a heat pump plays a crucial factor in choosing which heat pump is right for you. The larger your room, the larger the capacity of heat pump you require.

If you wish to install a heat pump in your bedroom, take particular care to opt for the quietest possible unit. If you get a noisy heat pump then you will not sleep too easily due to the high noise levels. Mitsubishi Electric manufacture extremely quiet heat pumps.

The number of rooms you wish to heat or cool also play a part in the selection of a heat pump. If you wish to heat or cool one room, a wall mounted heat pump is the best option. For two or more rooms, you can go for either a ducted system or two wall mounted heat pumps.

Ducted Heat Pumps

A ducted heat pump can be installed in your roof space, or in the crawl space beneath your house. A number of air grilles (or registers) are then cut into your floor or ceiling. These vents are then connected to the heat pump to allow air to circulate and be heated or cooled.

Wall Mounted Heat Pumps

These are usually mounted high up on the wall (high wall heat pump), or low down as a replacement for old electric or gas heaters. Wall mounted heat pumps are suitable for heating or cooling one room.

Correct Sizing

You must get the correct size heat pump for your room. Too small a heat pump will cause it to run at maximum throttle as it struggles to heat or cool your room. If a heat pump is oversized, it can lead to it cycling on and off, causing temperature fluctuations. To ensure correct sizing of a heat pump, always consult the professionals for a correct heat load estimation and capacity sizing.

Heat Pump Features

Modern heat pumps are very energy efficient and cost effective to run. They can heat, or cool your room to a comfortable level. Other features of a heat pump include air filters that trap dust and pollen. Water is removed from the air by dehumidification. This leads to cleaner, healthier air.

Most heat pumps also come with an infrared remote controller, and timer functions. This allows you to set the heat pump to turn on and off automatically when you know you will be away from home and when you will arrive home.

Heat pump installation

An air conditioning expert can usually install a wall mounted heat pump in around 6 to 8 hours. A qualified master electrician must do the final electrical connections, and the heat pump should be commissioned correctly by a qualified air conditioning expert. Failure to follow the strict installation procedures can and will cause damage to a heat pump. Always call in the professionals.

How do you keep the heat from rising from a gas fireplace?

In my living room there is a 17 foot ceiling. It stays cold all the time in the winter. We put a gas fireplace in and it keeps the living room nice and warm but the heat rises to the upstairs and it gets to be about 95 degrees up there. My house is a story and a half so the upstairs is opened up and you can look over from a loft and see the living room. Does anyone have any idea how to keep the heat down? We have a ceiling fan on to push the heat down and that does not work. We have tried to put it on clockwise and counter-clockwise and neither work.

You cannot defy the laws of physics however If you are lucky, I may have a solution. If your heating system has return air vents which can be opened and closed, try closing some of the ones downstairs and leave your furnace fan run constantly. This will pick up the warm air upstairs and redistribute it through the home.
If you have high and low sidewall return grilles, all the better because they probably have shutoff dampers built in for this purpose. You would alternately close upper or lower return vents depending on heating or cooling needs. It may even be possible to add high sidewall return vents depending on your home's construction.
