Sounds like bliss!Co cellphones charging? No computers connected. No alarm system. no appliances with displays? No porch lights? You NEVER heat or cool? No water heaters? No clocks?

(I don't even know anyone that has aircon
Me!
But I don't think I know anyone else.
My view is that modern houses should be insulated to the point where they need negligible Winter heating / Summer cooling, at which point the cost of providing, and running, it is tiny but the benefit for comfort and health is large. My Air Con comes on (only) when our PV is exporting to grid, sadly the house is so well insulated that it doesn't even begin to use up my surplus PV on "boiling hot days"
As a pointer if you want to keep diving into this side topic, research Passivhaus.I'll step back on this one, because here in the states that would effectively be unrealizable. And honestly, I believe that you couldn't do it anywhere. At an absolute minimum, you have to exchange inside and outside air to live healthy. And conditioning that air can be expensive. Simple things like windows become problematic.
Today's only a warm day at 86F
I've done a fair amount of research on efficient houses; I was actually working for some companies that were investigating them a number of years ago.As a pointer if you want to keep diving into this side topic, research Passivhaus.
1980 at the latest I would of though since production ended then... and then you bought a Tesla
Probably been better off with a 1980's Ford Escort Mk2 1.6 L

I have the same system and one thing you also gain is when on in air purification it also removes pollen, listen up all you hay fever sufferers as there is far more to air to air heat-pumps than the low running costs.Me!
Toshiba Haori system.
Our home Air Conditioning is famous amongst my Sons friends, as he's the only one online gaming with a jumper on in the height of Summer. Whilst all his mates are sweating and moaning about the heat.
I like ours because it has a Plasma Ionizer Virus catcher built in, so filters the air as they're working.
Installing a Hybrid deCentralised MVHR system this year with F7 HEPA filters as well, to compliment full climate control.

As I mentioned in my first post on the subject, I'm in the US, Georgia to be specific. Believe it or not, the entire world doesn't have the temperate qualities of Suffolk. We don't have the ocean effect to reduce the fluctuations in temperature.I went looking for a post I had made including house temperature graph and found a thread about Allergies and Migraine which has a good discussion about Passive Haus, mechanical ventilation, filters and so on. Would be a better place for discussion for anyone who suffers from allergies or respiratory issues or is interested in Passive Haus
So sure, in Suffolk the temperature in your house may only vary from 21C to 23C. That's because Suffolk only has a 15C outside average temperature swing.
In Atlanta, we've got a -10C to 40C swing that occurs here
And I am quite familiar with heat exchangers. I had one in my last house. While they are around 80% efficient, during the winter, they pump in relatively cold air. Cold enough that you can feel when the exchange is on.

In Atlanta, we've got a -10C to 40C swing that occurs here. In the northern part of the country, it can get down to -20C

massive west facing windows and a lack of knowledge at the design time of those to know to recess them or protect them from the summer sun somehow
I guess I'm trying to say don't discount a locally modified passivhaus as impossible
Oh, we only have electric heating (through choice). We also have electric water heating, solely via an immersion heater. Our whole property is also fully air-conditioned so lovely and cool in the hot weather. But, we also have solar and PWs and so far this month we have bought 1.2kWh from the Grid to power our property and electric cars. All-electric does work. Our EPC rating is a 90, and we just missed the A rating with our very high B rating. The EPC does not consider battery storage.We have no electric heating in the house so that's not an option. We have no electric water heating or aircon (I don't even know anyone that has aircon) so that's not an option either. I am talking about nightime hours after 11:30pm/midnight so normally no lights anywhere. We have some solar "security lights" that only operate when triggered. We have a mains security door light that might be triggered by the cat for 30 seconds. We are running a 15 watt UV tube on 24/7 for water treatment and we have a fridge/freezer. The other items like the alarm system, wifi router and wifi switches and device chargers are tiny power users.
I certainly agree with a MVHR system. When our property was built in 1989, we had one fitted and we were airtight. The MVHR system kept the air fresh. However, one winter it failed and overnight we had condensation on a couple of double glazed windows. Fixing the MVHR system cured the condensation.Temperature in my house very rarely goes outside 21C -23C I am in shirt sleeves the whole year, haven't worn a jumper in the house since we moved in
The mechanical ventilation air is filtered - so no pollen etc. Passive Haus is renowned for reducing respiratory illness. In the 7 years since we moved in neither Wifee nor I have have had a winter cough/cold (had one every winter before then), and Wifee was working in an open plan office with everyone around her dying all winter. So just the benefit of 12-ish hours in good air makes that difference.
People I speak to assume the house must be stuffy. Those who come here comment on the air quality Air changes are more than for an old draughty Victorian house! and because the vents are designed, rather than just having ill fitting windows, the air gets into all the corners - so no lurking mould spores, which are typical in UK housing stock in winter.
My advice to anyone contemplating a forever home, or anyone with respiratory illness, is build a passive house and have the comfort, financial and health benefits for the rest of your life
