Excellent vlog John another good installation. I find the heat to be far worse than the cold and this will probably be the way I will go the summers are just getting unbearably 👍👍👍
That makes sense I guess. A/C Chappy said best to set cold temp to around 21ºC and have fan on high as it then feels cooler rather than drop temp to 19ºC or so. Perhaps that's were we are winning on cold over hot performance.
# I mean we have air con into the 4 bedrooms for the summer but we have ordered an ASHP for heating the whole house and hot water as we felt that an integrated system would be easier for us than lots of air con units in our three storey house I do appreciate others may have a different experience and prefer the A2A.
HI John, another useful video. I did look at A2A as a potential for heating our house but we have quite a few rooms to so the ASHP seems to be the better option for us and it means I only have to set the temperature in one place rather than different rooms and times etc. As a matter of interest if you have it on heat mode in your studios does it stay at the same temperature or thereabouts? We have had two Daikin units installed in bedroom and if I set it to say 20.5 degrees it seems to keep heating all the way to 24 then back down over a number of hours. Installer is speaking to Daikin about this but seems to indicate this is normal which I don't believe so useful to know if yours stays at temperature say +/- 0.5 degrees or so. We do have a Mitsubishi unit which seems to heat the room to 1 degre over but it then holds it there. I am using the Sonof sensors to give me a guide as to what the room temperature is (so thanks for confirming last week). Many thanks, James
Thanks for watching James. Agree with your thoughts about ASHP with wet rads/UFH is a better option for homes with more rooms. I believe the environment feels better too, A2A blows hot or cold air and it's not a comfortable in terms or heating in my opinion as you end up with draughts of hot air wafting about. I've just looked at the Awair temperature history in Jill's glass studio. We have an Awair Element in there as it measures; temp, humidity, CO2, VOCs, PM2.5. The temp is set to 22ºC on the unit and room temp reaches between 20.9ºC - 21.1ºC so fairly on point. I have noticed that if you look at the readings for what the Panasonic units themselves think the temperature is sit's very different. It shows between 20º - 28ºC in the glass studio over the same time period. The photography studio connected to the same outdoor unit, with the indoor unit not on at the timereads between 24º - 31ºC. I don't trust the accuracy of the built in thermostats on the A2A units.
@@jamesmcfeely9150 This can happen if the unit is oversized. They have minimum compressor run times and rates of ramping up and down the inverter drive. It's all to do will oil return. As it speeds up, the room temp climbs rapidly then overshoots while it's slows again. Once the room is up to temp it should just tick over on a nice slow speed. Average bedrooms rarely need more than 1.5 to 2kW unit. Very large bedroom might push to a 3.5 if there is lots of summer solar gain - would allow it to keep up with cooling demand without having to use high fan speeds. Also worth checking if the installers sealed the hole where the pipes enter the building.... On both the outer and inner walls. Cold air can get pulled into the casing and affect the room temperature sensor. If you can't see easily, turn the unit off and put your face near the right hand side of the unit and get someone to open the bedroom door quickly, if there is a significant hole you should feel the cold air
We added A2A Mitsubishi multi splits last summer and the A/C was great. The heaitng wasn't so good, but took the edge off strong cold Northerlies that our house often suffers with, due to its design and some flaws. What's the Rushden weather website and does it import into HA?
Good to hear on your install It certainly pays to know you house and its quirks. Here's John's Rushden Weather website, not sure about linking into HA though: www.rushden-weather.co.uk/template/indexDesktop.php
@@barriedear5990 no, potentially not required. Link to Government changes due in early 2025: mhclgmedia.blog.gov.uk/2024/11/21/warm-homes-plan-and-heat-pumps/
Last year permitted development allows for ONE heat pump unit (Inc A2A) to be fitted more than 1m from the boundary if unit is under 0.6m³ in volume.....and for some reason this is only if you do not already have a wind turbine. There are 2025 changes (I think they have kicked in now) that allows 2 units for detached properties and the 1m rule has been removed.

Absolutely there’s no one solution that works for everyone.
