	RE: Is a Valliant Inline 6kW heater a BUS buster? By JamesPa, 12 hours ago Forum Air Source Heat Pumps (ASHPs)
	I think so but I don't know for certain. A cascade as grant describes it should cover 4-20kW without having to cycle, which again hopefully should be good for efficiency. I might suggest to swap mas...
	RE: Humming sound on new install. By ASHP-BOBBA, 13 hours ago Forum Air Source Heat Pumps (ASHPs)
	Sorry, I should also add these checks The ASHP must be dead level no exceptions, this helps the mounts on the compressor evenly dissipate the vibration form the compressor before it exits the unit. T...

	hmmmm - sadly the Mitsi's are more expensive (£2,700 the pair) and wider (by 300mm the pair). The Mitsi R32s are a little cheaper, do they have the same cascade capabilities?
	RE: Humming sound on new install. By ASHP-BOBBA, 13 hours ago Forum Air Source Heat Pumps (ASHPs)
	@adamk If you are willing to investigate you can take a large flat screwdriver, place it on the area near the noise and measure by simply gauging the volume of noise you hear through the screwdriver, ...
	RE: Is a Valliant Inline 6kW heater a BUS buster? By JamesPa, 13 hours ago Forum Air Source Heat Pumps (ASHPs)
	Fair enough. As I suggested above there are all sorts of games that could be played, but which are easily doable depends on the capability of the controller, which may vary widely As you are consid...
	RE: Midea ASHP – how to set weather compensation By cathodeRay, 13 hours ago Forum Air Source Heat Pumps (ASHPs)
	Mostly, I think, but with some caveats. I set the TIMER option (left most tab) on the Schedule Menu, not the WEEKLY SCHEDULE, just checking you have done the same? In the image of the wired controlle...
	RE: Midea ASHP – how to set weather compensation By pash44pump, 14 hours ago Forum Air Source Heat Pumps (ASHPs)
	@cathoderay thanks for that. I have set up daily schedule for 13.00-14.00 when I usually have PV power and OAT is higher on average. My controller shows the 7 day timer schedule as a calendar icon. Th...
	RE: Is a Valliant Inline 6kW heater a BUS buster? By GuydeB, 15 hours ago Forum Air Source Heat Pumps (ASHPs)
	So this is from Grant - can't fault them for speed of response to an email about 2 x 10kW: When using two R32 Aerona³ heat pumps connected in a cascade configuration, one of the two (the supplementary...
	RE: Is Your Broadband Router the Weak Link in Your High-Tech Home? By Scalextrix, 15 hours ago Forum Your Home
	I have been working on network resilience for a while. I use my own router/NAT/firewall device, a separate switch with POE+ that drives a WiFi access point and security cameras, then a NAS for media. ...
	RE: Is a Valliant Inline 6kW heater a BUS buster? By JamesPa, 17 hours ago Forum Air Source Heat Pumps (ASHPs)
	Incidentally this is the sort of thig you can do if you can measure your consumption, in this case from half hourly gas meter readings. Its how I sized my heat pump. Two professional surveys (3 hrs ...
	RE: Is a Valliant Inline 6kW heater a BUS buster? By JamesPa, 17 hours ago Forum Air Source Heat Pumps (ASHPs)
	Yes assuming the pipework permits this. Not sure this is the most efficient way to run even in the shoulder season though, probably better off just one of them running closer to full chat. Yet again...
	RE: Is a Valliant Inline 6kW heater a BUS buster? By GuydeB, 17 hours ago Forum Air Source Heat Pumps (ASHPs)
	ah that's interesting @jamespa - so could one 10kW (say) supply the HW and the UFH at 35 degs and the other supply the CH at (say) 45 degs? Then presumably in the warmer months we'd only run one anywa...
