A follow-up video
Added 2024-03-12 22:13:27 +0000 UTCHello all,
Some of the common misinterpretations from the last video are really getting stuck in my craw. For better or worse, I made this Connextras video to hopefully clarify this for anyone who needs it.

It's not scripted, so you'll have to wait for auto-captions, unfortunately. I'm planning to release this in an hour or two.

I’m enjoying these - very informative, but given I live in rented accommodation, I have no control over the fact that my flat has radiators and a condensing boiler. I have noted that electric plug in heating has a new (to me) option: the infrared panel heater - anyone have experience of these or know how they stack up efficiency-wise against conventional storage space heaters (silly expensive from past experience)? I figure if I can’t replace my combi, I could maybe buy a plug-in alternative, but if it uses massive amounts of electricity, it won’t be cheaper than gas.

2024-06-20 15:06:29 +0000 UTCMy understanding is that Daikin has the trademark for VRF and uses it to mean heat recovery, but other manufacturers can't call it that. That could very well be a US-only thing, or possibly even completely incorrect! But if it is incorrect, that's how most technicians are using it.

2024-03-14 16:47:34 +0000 UTCFWIW, I’m not sure installers and manufacturers are using VRF the same way you are. At least Fujitsu in Europe seem to call their entire AIRSTAGE line VRF, but only a subset (VR-IV) do heat recovery. At least according to their brochure: https://www.fujitsu-general.com/shared/pdf-feur-support-ctlg-3ef037-2401e-vrf-01.pdf This confused me no end when my J-IVS system, which I had called a “multi-split”, was referred to as a “mini-VRF” by the service tech.

2024-03-14 06:38:24 +0000 UTCIf your blower fan draws 500W just to run, two things come to mind. You're trying to treat an office building, or you need a new air handler.

2024-03-13 16:24:12 +0000 UTCRegarding run time. One major consideration you didn't take into account is air handler fan. Mine draws 500 watts just to run the fan. If my gas furnace had to run 24 hours per day it would use 12 kwh of electricity just to run the fan.
