Mini Split Heat Pump Ductless for Heating and Cooling


What's the flexibility of ductless mini-split heat pumps?

Ductless mini-split heat pumps give you flexibility in heating or cooling single rooms. There's no need to install air ducts, and each indoor unit features a thermostat.


How about noise?

A ductless mini-split heat pump is much quieter than a portable or window air conditioner because you don't hear the outdoor unit(compressor). You only hear the fan in the indoor unit.


Are mini-split heat pumps energy efficient?

According to the ENERGY STAR organisation, the certified ductless mini-split heat pumps use 60% less energy than standard home electric resistance-based heating systems. Cooling costs are 30% lower than conventional room air conditioners.

Quality ductless mini-split systems also feature variable speed motors in outdoor units. If the heat or cool demand is low then the system will run at decreasing speed, therefore consuming a lesser amount of energy.

From where is the mini-split system powered?
Indoor and outdoor units are powered from the outdoor unit.


How to select a ductless mini-split heat pump?

The higher the SEER and HSPF numbers are, the better the energy efficiency is.
SEER stands for Seasonal Energy Efficiency Ratio, and HSPF means Heating Seasonal Performance Factor.
The mini-split system you want to buy should have:
- a SEER number of 20 or higher,
- an HSPF number of 8 or higher,
- the ENERGY STARĀ® label.


What BTU rating should your heater/cooler have?

(BTU: British Thermal Units)
A higher BTU rating means more power.
12,000 BTU equals one ton of water heated one degree Fahrenheit every hour. (1 BTU is one pound of water).

Examples:
A unit of 9,000(9k) BTU will be suitable for bedrooms and porches.
A unit of 12,000(12k) BTU will be suitable for a space of about 500 square feet.
A unit of 18,000(18k) BTU will be suitable for a space of about 750 square feet.
A unit of 21,000(21k) BTU will be suitable for a space of about 1,200 square feet.
A unit of 24,000(24k) BTU will be suitable for a space of up to 1,500 square feet.

To determine the appropriate BTU rating needed to keep a room or house warm or cold is usually done with the so-called Manual J Calculation.
