Welcome to our Fujitsu RLS3 Vs LG Prestige heat pump show down post.
Want to check out other posts from this series?
In this post we’re going to compare two very popular and highly efficient ductless mini split heat pumps in the LG Prestige and Fujitsu RLS3.
To ensure we’re comparing apples to apples we’ll only be looking at the most important specs for each unit:
- Heating capacity
- Operating temperature
- HSPF (heating seasonal performance factor)
Let’s get started.
Below is a straight comparison table of both the LG and Fujitsu ductless heat pump units.
In the table above there are two different Fujitsu models shown. The one in the middle is the xltH model. You’ll notice it operates down to a lower temperature and also produces more heat than the standard RLS3 at lower temperatures. The reason for this is it includes a pan heater.
The nominal heating rating for a mini split system is the amount of heat, in BTU’s, the system creates at 8°C outdoor temperature.
Fujitsu RLS3: 16,000 BTU
LG Prestige: 13,600 BTU
The Fujtisu wins here over the LG.
When you compare the low operating temperature of two or more mini split heat pump systems don’t just look at how low does it go. You also want to look at how much heat the unit is capable of producing at that temperature.
Fujitsu RLS3: Operates down to -21° C and produces 15,500 BTU of heat at -21° C
LG Prestige: Operates down to -25°C and produces 9,520 BTU of heat at -25°C
For the low operating temperature we have to give the win for this category to LG, but notice how much more heat the Fujitsu is producing than the LG.
Heating Seasonal Performance Factor
We love this spec. If only comparing heat pumps at a glance be sure to compare the HSPF ratings for each. The higher this number the more efficiently that heat pump can create heat.
Fujitsu RLS3: HSPF of 14.0
LG Prestige: HSPF of 11.5
In a nutshell this means the Fujitsu can produce the same amount of heat as the LG more efficiently when compared at a reasonable outdoor temperature.
The Fujitsu wins this category.
Warranties on ductless heat pumps are very similar to those of new cars. Different components have different coverage durations.
The three components of a heat pump warranty are usually:
Here are the warranties for these two units:
Fujitsu RLS3: 10 year parts and labour on compressor and indoor unit
LG Prestige: 7 year compressor, 5 year parts and 1 year labour
The Fujitsu with the longer coverage on all components as well as including labour wins in this category.
Let’s recap the comparison of these two units.
- The Fujitsu RLS3 produces 2,400 more BTU’s of nominal heat than the LG Prestige
- The LG operates 4° lower than the Fujitsu to -25°C however even at -21°C the Fujitsu is still producing over 15,000 BTU’s of heat
- The efficiency rating (HSPF) for the Fujitsu is 2.5 points higher than the LG
- The warranty on the Fujitsu is 10 years parts and labour compared to the 7 year compressor, 5 year parts and 1 year labour on the LG
The Fujitsu RLS3 over all is a superior unit to the LG Prestige. It produces more heat, has a higher efficiency rating and superior warranty.
There is an option to upgrade the warranty to 10 years on the LG, but it is an additional $399.
As of July 2015 a 12,000 BTU Fujitsu RLS3 is approximately $4,250 + HST installed while the LG Prestige is $3,750 + HST installed. If we increase the warranty on LG to 10 years for the additional $399 then the price differential becomes only $100. Making the Fujitsu a far more attractive unit.
