Using the aircon of your EV car to cool your house

Thoughts anyone?

A bit too late now but got me thinking.

What impact would that have on the electronics/cooling components having to work overtime.

Just buy a basic air conditioner unit or open the windows.

With outside temps of 37.6 C today opening your windows is the last thing I would do

Can’t imagine it would be great for the EVs battery. Better to buy a portable AC unit, which will be getting more use in years to come.

Houses on these islands are built to retain heat, you can do basic things like close windows and blinds to reflect the sunlight and keep the rooms cooler during the day. Ventilate the house when it’s cooler in the evenings.

Many methods, the
Most effective i have found to cool your house is using rising heat, create a natural updraft called the stack effect to suck hot air out and pull cool air in. This method can be enhanced by removing the loft hatch. Cutting out sun is also very important too. My house is a steady 22c today.

And where is this cool air today that you are pulling in??

We have some wind today and hot air out the upstairs windows.

Unless you live somewhere North and/or West of Darlington, I and the laws of thermodynamics call BS on your 22C.

I'm sure it'll be fine. Not like it's drawing the 100's of amps that the drive motor will be pulling day in and day out.

We have some wind today at 37.6 C and letting that blow in would heat our bungalow to roughly the same temp.

Maybe it works to cool a house down to 22 C but I very much doubt it.

I bet you let cold air in the upstairs windows during the winter and by the time it has reached downstairs your house is sitting at 22 C.

I know it is AI generated but this calls bullst to your claim

That not quite how it works. The hot air rises and cool air stays down stairs

I disagree. We live in an old stone cottage. Thick stone walls hold the heat to a lower level,, 22 Deg C inside, but 25 Deg upstairs for us. The high thermal mass means it takes a while for temperatures to change indoors.

Scotland.

PH’s London crew should be good enough to return the favour with some helpful advice for dealing with the snow.

You're in Glasgow right?
Don't you think that highly important bit of information would be useful? Maybe?

[Big Nanas]

Just to add.
We're in Surrey, living in a 30s Bungalow with solid, no cavity walls and closing windows and curtains all day/open as long as possible before bed worked at first, but today it hasn't.

The house has retained the heat in the walls and so it started this morning at 28c.


But to have a go to answer the question, it would be like opening your fridge/freezer door and expect it to cool your house. It won't.

The compressor will be designed for the volume it's cooling, not something 100x bigger

Perhaps. But it'll also likely be designed to maintain a cabin temp below 20 degrees with a 40 degrees ambient while moving at 80mph.

Stick the car in the shade and don't expect it to cool the room to 18 degrees and it'll still make a noticeable difference I'd wager.

Just get a quote for proper aircon, its cheaper to buy and run than most think.
Our bungalow is long and L shaped, two aircon units one of which is a splitter that serves two rooms has kept the whole house between 18 and 20' most of the day, we switch off 2 units between 4 and 7pm and only leave the one unit running in the room we're mainly using.
A smaller home with even 1 unit would still find a huge difference.

Life changer, dog loves it too.

[Hackney2]

Quite frankly an absurd idea.As the previous poster said,just install a ducted reverse cycle A/C system in,or a couple of Split(wall mounted) A/C units in a couple of rooms. Ducted is the way to go. Very common here in Australia, & if you have a decent size Solar array,you are laughing.
