If you have following this blog you will know I am a big fan of reverse cycle air conditioning for room heating due to its amazing efficiency..
That however doesn’t apply to our bathroom.
This might look like a reverse cycle unit but its actually a rather smart looking fan heater.
So why am I happy with the 100% efficiency for this heater rather than the 300% efficiency of reverse cycle.
Well there are a few reasons:
- The unit was fairly inexpensive at less than $100 as opposed to around $2,000.
- It doesn’t actually use much power as it runs for less than 10 minutes a day over the winter months only. (we are 3 minute shower people) That’s probably no more than 12 kw hours per year (Power cost of under $4 a year)
- Being a fan heater it starts to warm up the room within 30 seconds whereas a reverse cycle unit will need to run for several minutes meaning that there really isn’t a power saving benefit for short term heating.
- The fast response is more convenient.
This just shows the most ‘efficient’ heater isn’t always the best solution, particularly if the heating is only for short periods. .
