Heaters
#1
Wow, I had my first "heaters" today... Man they were so hot I couldn't even touch them. My poor Opus! All 6 grey cells from the same pack as well. Now I know where they get their names from! :-)

Hahah yup!

Interesting that it was the greys that went thermal. Usually it's just the Sanyo's.

I watched your 1st video. I think you meant to say "air to air heat pump", not "inverter". They're very good at heating the ceiling while leaving the space we inhabit cool. Try using a IR temperature gun (eg. https://www.amazon.com/dp/B00837ZGRY ) to find hot spots and cool spots in the rooms. If there is a large temperature difference, use a circulator fan (eg. https://www.amazon.com/dp/B004XZDCQW ) to move the cool air up and force warm air down. I like to use the larger ones on the slowest settings for quiet 24/7 operation.

It seems counter-intuitive, but it makes a huge difference both in comfort and energy savings. I've now lowered my thermostats down to 18C, and it's just perfect!

I thought the Sanyo's bypass the thermal stage and jump straight to BOOOOOM!!!!  Big Grin

Hey thanks :-) Do you know, I was looking at a thermal camera just yesterday!

I totally agree with your idea regarding the fan.  Last year we bought one of those log burner fans that requires no battery, it uses the heat differential to drive the motor - wow, they're awesome and really do work!  Our air to air heat pump (often called an inverter over here) broke last week anyway so this sh@t just got real!! LOL!

Thanks for the support on the channel, it's going to take a long time to build an audience but I'm enjoying the sharing so far and the next 3 videos will be uploading over the next 2 weeks.
