Parece que no va a quedar de otra más que conseguir un aire acondicionado de verdad. Tenía uno portátil que ni enfriaba tanto y consumía un chingo de luz.

Recomendaciones para aires que sirvan para enfriar una recámara de unos 3x3 y que no me sangren demasiado el recibo de luz?

Does anyone have recommends for book or website I can use to educate myself on options for upgrading a postwar bungalow from a gas furnace + AC to heat pump(s)? The book I have is OK for basic principles but I’m looking for more what units are available, cost, installation pitfalls.

I have asthma which is aggravated by the current system blowing dust around summer + winter. Primary motivation is comfort, better energy efficiency would be bonus points. #HVAC #HeatPump #minisplit #renovation

Last fall, I installed a #Turbro #MiniSplit #HeatPump from #HomeDepot in the back yard shed we call the "MicroBarn". Read the Alt Txt - that's where the story is. But this is about #Histeresis and failure to exploit it.

Allyson Chiu: Why you shouldn’t buy a basic window AC unit: A basic window unit is typically cheaper than other models and relatively easy to install, but they guzzle energy and can contribute to emissions.

"With temperatures climbing into the triple digits, running out to buy a window air-conditioning unit might seem like a simple way to beat the heat.

But while these air conditioners can help keep you cool, experts say you should consider other options."

"A basic window unit typically has a lower initial cost than other models and is relatively easy to install, but they guzzle energy, straining electricity grids, and can contribute to the planet-warming emissions driving extreme heat."

Any smart #energy people available to give me a primer on waste heat from #minisplit #hvac etc. In regards to local heat Island effects?

Cooling trick for a bedroom #Heatpump for sleeping:

As you know if you have one, a #minisplit heatpump will not run in a way that necessarily respects the thermostat setting. Two problems you get sleeping with the AC: it overshoots, so you freeze. And it starts to modulate when it approaches the setpoint, so it spools up and down distractingly.

So I use an external thermostat, a Cielo Breeze. It has a setting called “comfy mode.” 1/

I mean, what percentage of Vermonters even have air conditioning. 40, 30, 20 years ago I didn't know anyone who had it in their home in #vermont. I guess 20 years ago I got a window unit for my office. Window unit here in the livingroom is now superseded by a #minisplit #heatpump. I've got to imagine this event coming up is going to be potentially deadly, some elderly people in poor health in an upstairs bedroom. #climatechange #globalwarming

We turned the heat down a couple degrees on the minisplit heatpump while we were gone for Christmas. Our basement and main floor are heated with the HP, top floor is baseboard (turned those down too).

We left Saturday and returned today/Wednesday. Temperature went from normal around 21-22°C down to just over 18°C (64°F).

With no one in and out of the house the temperature only really fluctuated with the temperature outside, which was mainly stable around 2-4°C until Monday night when it warmed up to 10°C.

I am probably the only person that finds this interesting.

IT’S ALIVE! Only one real flub up but was quickly fixed, remember to CORRECTLY torque the line set!

Work in progress! #minisplit

Went to drop off a some old house furnishings we were selling this morning and making conversation with the woman buying them.

“Yea, this is for the new house we’re building”

“Possibly weird question, but what are you putting in for #heating?”

“Oh, our electrician friend said we wanted #minisplit #heatpumps”

It’s the little wins some days

I've always called them "mini-splits," which is a very popular category of heat pump not mentioned in this article.

How about #minisplit?

Also, yea, I check out the brand spanking new LGs and Mitsubishi's when I walk these Boise alleys and critique installs. It's coming along.

Wondering whether to let an air source #minisplit #heatpump run and suck in snow during a heavy storm, or if it's better to turn it off and burn oil during the heavy snow event? Any #greenenergy #heating geeks with an informed opinion? I read a study that moderate use of the defrost cycle uses like 5% or 7% extra energy (it seemed like a good study, but I didn't save it). But in heavy snow it will be freezing solid over and over.

#Fujitsu #MiniSplit #Heatpumps holding up on this pretty cold day in #Vermont. -11F now and dropping, turned off the downstairs unit that was holding the line all day. Did it because the woodstove has a nice hickory log in it. Upstairs unit is still heating the bedroom. These things work.
