You don't need to look at Fahrenheit to see there is energy in zero degrees c. You just need to know that absolute zero is -273deg Celsius and every degree above that has some energy
Interesting video, but I cannot agree (in the nicest possible way). I have air to air and I personally love it. First, it's quiet, inside its quieter than a large blade ceiling fan and on night-time setting hardly audible. Currently, in my living room, it's registering 40db. It's very cheap to run. It filters the air, not only that, it dehumidifies it. Most modern houses are not well ventilated, and damp and moisture can take hold. Air to air pumps this moisture outside, keeping the house free from black spot mould and high humidity. This makes it an excellent and cheap way to dry washing on rainy days. Also excellent for when a kettle or saucepan is boiling. As for air circulation, it's programmable, meaning it will only blow air where I want it to. On my Midea, there is an "air magic " mode that diffuses the stream of air entirely if you really dislike feeling the breeze, especially at night in the bedroom whilst sleeping. Total cost for my three units fully installed £6k. No radiators, no pipes and the unit takes less than a minute to come on. This is the second house I've had this in and I wouldn't be without it.
Hi, I am signed up to a 5 year service plan which costs £240 pa. It's more than my gas boiler but there are 3 units and one is high up on my gable. To be fair I am saving more than that on the running cost. All three units set at 23° on auto cost less than half of what my gas boiler cost. But because I have solar and battery in reality I don't use any electric from the grid. Even on a grey overcast day my panels generate more than the A2A system uses. As I type this I have only the living room unit on at 23° and it's pulling 0.376 kw from my battery Inc my tv and fridge freezer. Forgot to say my total system cost would have been less but my upstairs unit is larger than I needed to allow the addition of one more inside unit if I decide I need it in the future.
apparently , the reason don't give the grant to air>air system is that in the summer people would use it for air conditioning and put load on the grid.
I heard this being said somewhere else but I disagree with there guess, most with heat pumps have solar and in the summer local over voltages due to excess can be an issue if they sucked it with air con it would stable demand remember the UK rarely gets hot summers maybe 5 days a year you’d need air con
@NicolasRaimo hi could I suggest it's because A2A doesn't heat the domestic water so people might still use their gas boilers. Same reasoning as why plug in hybrid cars are not encouraged, the government thinks people won't charge them and still run the car off the petrol engine.
The real reason is that the UK boiler/plumbing lobby has persuaded MPs, who may not be the most discerning when offered inducements to support an industry, to oppose AtoA. This is because the boiler/plumbing lobby views AtoA as a significant threat to their ongoing future. To clarify, lobbying is often perceived as a sophisticated form of bribery.
Did you know that heat pumps can also cool the radiators? You have to watch the dew point to avoid condensation drips and it helps to lag all your pipes but you can get a few degrees of cooling in a heat wave that's worth having.
I think you should also take in to account the size of house? I had no wet system in my little terrace plot. 2 up n 2 down rooms. I fitted my own air to air to heat the up stairs in 2000. I don't mind the low noise and when up to Temp it becomes very quiet. Last year I replaced the gas fire for far infrared underfloor film. It's not always about getting a government hand out. If the product they are pushing doesn't suit the property. For me, I have solar panels that run the Air con in summer for free. And winter the heating is quick and takes up less wall space than radiators. Down stairs in summer, the cool air tickles down and in winter the underfloor heating keeps me feet warm! This suits me, but not everyone. Each place is different.
Hi Nicolas - just a point a "casket" is a coffin where as a "cassette" is what people refer to with ASHP's ~ it might just clarify and save confusion. KR AndyT.
I'm planning on having both A2W and A2A - my home already has underfloor heating (currently heated via a gas boiler) and I find it a very comfortable heat emitter. But my home is an oven in the summer, due to a lot of south facing windows and super insulation, it is often above 30*C even at 5am! I'll need to install the A2W system first, to get the £7,500 grant, then install the multi-split A2A system. I grew up with A2A heat pumps as a child and am well aware of the drafts they create when heating.
Daikin are now releasing a Multi + air to air system which has a heat pump heating a 90 or 120 l tank to give hot water and also connecting to up to 3 air fan heaters. Because this system also heats water, it is virtually the same system as the current air to water system which qualifies for the £7500 grant. So if it is producing both heating of the home with green production of hot water then it too should qualify for the £7500 grant. Now that would be worth while. The main disadvantage of the air to water is that the heating of the home is not instantaneous and to run it efficiently it should be run for long periods of time. How can you therfore predict when to turn it on and off. A summer evening can be chilly and an air to air can give instantaneous warmth whereas by the time you decide to turn on the air to water system, you've gone to bed before you are warm! Norway, having a colder climate than us, are using air to air. Why?
The system has feed in from weather outside but also internet connected, the cosy6 is now fitted and has a a range of heat for water, it can heat to 60c which would give me very warm rads but I ran my boiler at 50c same as a heat pump
Daikin do a multi-split system where one of the splits can be used to heat your hot water. Only issue is it's a relatively small tank at the moment (120L I think) so they have not bought it to the UK yet. But hopefully one day... It's a shame no grant for air to air.
Hi Nick, Good video (as usual!). I have a question that is about your decision to wait for the Octopus Cosy6 heat pump. I wondered if they've given you a date when it will be available? Thanks, Phil
We were thinking about air-water heat pump and were halfway through the process of having all our insulation upgraded when our boiler died. So we had to get another gas boiler and now we're tied to gas for ages. :(

Yep, exactly. Looking at Fahrenheit to explain this just makes it more confusing.

I like idea of air to air better too. What's maintenance like? How often is it costly etc.

@Beorn. sounds good 👍🏻 thanks for answering
Do you need a unit in every habitable room? How do you handle the smaller spaces like kitchen and bathroom
?
Great info. What do you do for hot water?

Having both in my bedroom I can confirm the A2A useless slightly less than the ceiling fan.

@@Beorn. as suggested in video this is most likely reason as grant is “bus” meaning boiler replacement

Still waiting for cosy6?
I disagree, a snificant protion of our housing stock is off gass grid flated dwellings. These properties it"s far more practical for Air to Air
"if u look into Fahrenheit there is plenty temperature left in 0°C"
Now my brain has a knot.
Do u care to explain?
0c is 32 Fahrenheit what I was meaning by this is many assume 0c has no useable temperature left
