HEAT PUMP BUYING GUIDE
Heat pump systems, capable of both cooling and heating, pump heat from a cool environment to a warm space to warm air indoors during the heating season and move heat from your residence to the warm outdoors during the cooling season. Since heat pumps transfer heat rather than create it, the running expenses are greatly lowered.
Types of Heat Pump
Air Source Heat Pump
Water Source Heat Pump
Ground Source Heat Pump
- A heat pump that uses water as a heat source is called a water source heat pump. Water from the sea, river, lake, and well are used as low-temperature heat sources. On the one hand, the natural environment restricts the water source heat pump. On the other hand, water treatment and anti-corrosion measures need to be taken in the heat pump system, making it uncommon to promote compared with the other two types of the heat pump. In fact, in many countries and regions, there is corresponding law being issued to prohibit the use of groundwater resources as the low-temperature heat source of heat pump systems.

- ground source heat pumps use subsurface thermal energy to transmit heat similarly to air source heat pumps. They provide significantly more effective functioning because of the earth’s constant temperature. However, The ground source heat pump has the following disadvantages: The installation cost of the ground source heat pump is higher than the air source heat pump, and the construction conditions can be very harsh. It may leak and cause land pollution. Moreover, it may cause large-scale cracks in the land.
Purchase Notes
Climate
Heat pumps are effective in most countries, especially in areas with modest heating and cooling demands and without significant temperature variations. However, it is recommended to purchase an auxiliary heating system in areas with exceptionally cold weather.
Size
The size of the heat pump is another important factor to consider before purchasing. Whether the heat pump is too small or too large, it will not cool or heat effectively and raise your energy expenditure. To solve the sizing problem, you need to ensure that the contractor carefully considers the pump size to suit your needs. The size calculation should take wall thickness, insulation, windows, air filtration into account.
Cost
The expense of purchasing and running a heat pump is a substantial expenditure. Before you buy the heat pump, you should think about the system’s efficiency rating. The initial cost of the heat pump may rise since the efficiency rating rises, but the monthly cost of running a heat pump will eventually reduce. The air source heat pump has significant energy-saving effects, saving 70% of energy and shortening the investment payback period.
