Ceiling fans make a huge difference when its hot
I have gardening water spray misting kit attached above my west facing windows/bifold doors. When on the cooling mist, cools the air before the westerly wind blows it into my house. I then open Velux we have on the east roof and the hotter air can get pished out by the cooler air coming in. Uses very little water.
I also hose down the roof and even wash the cars in the evening helps take the temperatures down around the house.
Best option is to add trees, bushes and shrubs to help block the sun from heating up surfaces. Good for you qnd the planet.
Turn of fridges and freezers – they create heat in the house 😂
Excellent video Heat Geek! Totally agree that a portable AC is very handy to cool my house or home office for those few days of heat wave. A whole house system would be expensive and OTT. Also, I use my own solar electricity, so great parity there.
You touched on this with awnings but for other windows, external shutters make a huge difference. Stopping the heat from entering the house makes all the other steps much more effective.
Space blankets on the inside of your windows, cheap easy temporary fix, house looks like a weed farm but it works.
I just have fixed AC multisplit units, keeps it nice and cool, in the day works on solar power, and in the winter i use it to heat the home, so an air/air heatpump. best investment i did.
Hang the curtain outside of the window to keep the heat out…
For anyone that likes nerding out on this stuff, look up the PMV and PPD models for thermal comfort. You might be quite surprised how much infrared radiation has to do with perceived thermal comfort and how (relatively little) air temperature does. It was quite eye opening for me and got me thinking about more than just getting cool air in and hot air out.
Insulate the f*** out of your roof to stop the heat from the tiles heating up the attic
The problem with the all in one air conditioning units are that by their nature they have to suck in air to blow it over the heat exchanger. Some gets pushed out into the room but some gets pushed out the hot air pipe. This creates negative pressure and causes air to be sucked in to the room from the hotter areas. Mini splits have the heat exchanger outside and the chiller inside so they don’t need to extract air out of the room just run it past the cooler. More efficient and no noise from the compressor so quieter.
Dehumidifiers do not cool the air down they warm it. Adam is wrong on that advice especially if you purchase a desiccant one. While they do effectively function the same as the all in one air cons they pass the air over the chiller and the heater in the same path so they effectively make the air hotter but dryer. This will cause your sweat to evaporate more and you may notice the difference, but it’s just making your house feel slightly less like a sauna.
The last tip, putting the heat pump into cooling mode, will that not cause condensation? I've seen a pipe system that you fit in the wall and ceiling to cool down the house, had the same question for those too.
Portable air-conditioner venting hot air out the open window. You need to block the hot outside air from coming in through the area of the open window around the exhaust pipe to increase the aircons efficiency.
There will be a water shortage now 🙂
I have air conditioners everywhere except my kitchen. Is it efficient to use a portable air conditioner in there?
I wish window fans / whole house fans were common in the UK. On summer nights there's hardly any breeze which pulls air in through the window.
I can sometimes get air to come in by putting a fan on the outside window ledge (but this is quite unsafe!) If only they made window fans which fit UK windows.
Maybe an explanation about the sort of insulation used would help. Like wood fibre against PIR….. obviously not a quick tip but very important in the design fase of a fi extension with a flat roof. I think it’s called the decremental time…… cheers!
Outdoor curtains are a winner when it's really hot for our west facing living room with too big windows. Poor man's awning but might work better where the walls aren't strong enough. Keep that heat out altogether!
New developments should include external solar window shades for sun facing windows as part of building standards. Government constantly say weather extremes are expected yet fail to introduce sufficient mitigation strategies.
I'm in Aberdeen……🤔
@HeatGeek, I'm currently doing a major rejuvenation of my home. I've decided to install UFH on both floors with a Valliant aroTherm plus.
I like the idea of using it to cool, as well as heat, but Ive been told to insulate between the two floors. If I want to use it for cooling too, would it be better not to do so?
Paint the outside of your windows with yoghurt. Produces a temporary solar coating to reflect the sun. When the heatwave is over, just wash it off!
Don’t cool your roof if you are on a water meter.
Best change we made to cool our house was installing solar panels on the roof. Made a big difference to the top floor room especially.
The front of my house is south facing with some block paving in front if it, if its really hot I water the front of the house and paving to reduce the heat be emitted over night
Does the air source cooling chip also work with a radiator air source system?
Excellent video as always, got an extra like for that bib alone! 😛
Question:
I'm guessing it's not worth trying to get a chip for an air to water heat pump to try and cool the radiators if we have more heatwaves? Only air to air or underfloor heating would work this way?
Our loft is way cooler since we had solar panels put on the roof.
Good video, short, to the point and based on sound physics.
Put a tinfoil hat on your house.
Fantastic video! Feels like these tips will become more and more necessary for the years to come (for obvious reasons). Extra question: does it make sense to install simple tile vents high up in loft to release that additional build up of heat? And does it also make sense to bolster insulation to stop downwards radiance of that thermal mass heating upstairs rooms below the loft?
What about installing A2A heating/cooling and using it as air con?
These can all be condensed to six tips:
Get window films
Super insulate your roof (via Epdm)
Get a DMVHR everywhere
Cook outside
Use fans
Use your floor
A DMVHR is relatively easy to plonk in compared to an MVHR in existing houses but you should still get it properly designed. I'd rather get an MVHR but with already low ceilings and an already existing house, that's a bit of a no go. A DMVHR in an existing house is also much cheaper than an MVHR in an existing house
I don't see the need to get say one of those cowl vent thingies if you've just got a DMVHR which then works in your favour in the winter too.
One extra tip regarding floor cooling. The cold is just hanging above the floor, in order to cool the whole room put a large ventilator on the floor and let the air fully strike over the floor surface. The cold is distributed through the whole room and will also remove heat out of the walls.
Further more, continue with your nice informative movies I point a lot of Dutch people to them.👍
