Central heat pump our mural heat pump?
For the professionals at Climatisation B.S., heat pumps hold no secrets. If you want to buy a heat pump and you hesitate between a central or wall-mounted model, take a few minutes to read the following.
The central heat pumpFor optimal heating and air conditioning quality, the central heat pump is unparalleled! Requiring more complex installation than a wall unit, it is not suitable for all homes: you must have a duct system, or have one installed. In "heating" mode, the external condenser of the central heat pump captures the hot air. It then circulates it through an evaporation system using a refrigerant that moves through a network of tubes. This is then propelled and distributed in the wall ducts. In addition, a second heating mode must take over at temperatures below -15 ºC. On the other hand, when you activate the "air conditioning" mode, the operating system of the central heat pump proceeds in reverse order, that is to say that the evaporator circulates the hot and humid air in the pipes then discharges it into the outside air.
The central heat pump has the following qualities :
- It distributes the air evenly thanks to the wall ducts;
- It offers more uniform freshness than the wall-mounted heat pump;
- It provides nearly 85% of your home's heating during winter;
- You can take advantage of a dual-energy tariff that provides you with attractive savings if you use a fossil-fuel heating system in combination with your heat pump.
The wall-mounted heat pumpThe wall-mounted heat pump is an "economical" solution that requires easier installation than a central model. It has an evaporator inside the house and a condenser outside. In "heating" mode, the device stores hot air particles from outside and then circulates them inside. Like the central heat pump, an additional forced air heating mode must be used to ensure sufficient heat in winter. When you select the "air conditioning" mode of a wall-mounted heat pump, the hot air is collected by the evaporator, transformed using a system of evaporation and condensation of a refrigerant liquid, then discharged into the outside air.
Here are the main advantages of a wall-mounted heat pump :
- It does not require duct installation work in your home;
- It does not dry out the ambient air;
- It saves on heating costs compared to electric heating;
- It is not very noisy;
- It is possible to install more than one wall-mounted heat pump if you own a very large property.
Lets talk BTU! Depending on the area to be air-conditioned, the amount of BTU (unit of measurement of thermal energy) required is decisive. For example, for an area of approximately 400 square feet, a 7,500 BTU unit is recommended. On the other hand, for an area of 2000 square feet, it is necessary to count on a device of 30,000 or 36,000 BTU. Certain factors such as, the age of the residence, the quantity and / or the quality of windows, the insulation is to be taken into consideration in the choice.
