Seems possibly to have been a manufacturing fault, and the units shipped to you were not fit for use for a reasonable lifespan. You may be due at least partial refund? Our triple glazing was a bit explody - I think because it was a new manufacturing line - and we had no arguments at all getting things fixed under our warranty. https://www.earth.org.uk/triple-glazing-3G.html#Failures

I deny everything.

This ought to be a poCcast, to rival Joe Rogan...

Well, get one that is water- and energy- efficient, that she likes, I suggest. Cold only is fine.

Both circulating hot and washing unnecessarily at 40C or above are huge consumers of energy. (And washing too hot ages clothes prematurely.) That costs money and climate emissions. The OP was talking about 'savings' from a dual-fill machine. Better savings would come from NOT having circulating hot and NOT washing hotter than actually needed.

One huge energy saving (~80%) is to run washes as you can cold, so buy a machine that can do that. We do everything except bedding on cold. https://www.earth.org.uk/note-on-Zanussi-ZWF01483W-freestanding-washing-machine-REVIEW.html Also as @JohnMo says, a water- (and thus energy-) efficient machine may not draw enough hot for it to reach the machine at all from the tank/boiler.

Transition Town Totnes 2025 Open Eco Homes event and invitation.
DamonHD commented on MikeSharp01's event in Community Calendar
FWIW we will be opening some 'eco' homes in Kingston-upon-Thames including mine that weekend. https://www.ttkingston.org/events/item/55881829 -
Season 2 will involve glazing of some sort, surely?

No one here but us chickens (and Steamy).

Mimicking solar panels from an AC supply

Octopus heat pump, do they still supply Daikin
DamonHD replied to DanielE's topic in Air Source Heat Pumps (ASHP)
Well yes, I had Octopus redo the calcs with some extra information and the heat loss was halved and only one rad needed swapping. Octopus has to tick some MCS audit boxes, but are open to rational haggling in effect. After some observation including a couple of days that hit design days (-2C outside) I adjusted my weather comp to (50°C/-7°C, 25°C/14°C). https://www.earth.org.uk/heat-pump-16WW-control.html#weather -

DamonHD replied to DanielE's topic in Air Source Heat Pumps (ASHP)
I adjusted the weather comp curve immediately, so we don't get up to 50. -

Yes, just did for me in November: https://www.earth.org.uk/heat-pump-16WW-control.html -
We we meant to have stopped nipping round in the night to pee on your walls yet? The train fares are getting too much... Also, I'd like to check that I have the right address...

For at least one of my 3G units the nominally-expert third-party fitters left a ~1cm gap down one side of the unit, which I only discovered sometime much later, so basic errors can happen...

Hi, In case of interest here, these are talks that we will be giving to householders considering greening their homes in Kingston-upon-Thames. (There are a couple of PDFs still to land: the event is May 10th.) https://www.earth.org.uk/Kingston-Efficient-Homes-Show-2025.html We did similar last year and the year before, and you can find links to those.

Oh, we were meant to ask first? Sorry...

One swerve I helped with was to get solar PV for a listed property, within the curtilage for FiTs but outside the historic curtilage for listing purposes! https://www.earth.org.uk/installing-solar-PV-for-electricity-at-home.html#farm So there may be subtle things like that that help...

ASHP - Weather Compensation AND Zoning?
DamonHD replied to SBMS's topic in Air Source Heat Pumps (ASHP)
I am running WC, volumiser and bypass, with each (micro)zone able to call for heat, and no zones permanently on. Works efficiently and pleasantly for us, and typical cycles are an hour or (much) more. https://www.earth.org.uk/heat-pump-16WW-control.html -
Filled up (as did all other energy storage) today for the first time this year... It's been a sunny March round these parts...

Water hammer, when the washing machine starts and/or stops drawing water?

You may find that diverting more slowly will let the tank absorb more heat before the thermostat cuts out by letting heat dissipate better in the tank. I have a grid limit of 8A/2kW set for my Eddi (immersion and heat battery downstream).

ASHP + Solar PV + Battery - Choices
DamonHD replied to Diarmid's topic in Air Source Heat Pumps (ASHP)
I am using a Thermino *alongside* my heat pump DHW tank, and I don't expect to be paying to import much electricity between now and September to make DHW... https://www.earth.org.uk/reconnecting-the-16WW-heat-battery.html -
I absolutely agree about getting condensing boilers to actually condense. Anyone who wants to take up my rad stickers idea (now that DESNZ and Ogfem might be a little more receptive than when shown last time, under the previous government) and run with it is very welcome - I simply do not seem to have time. https://www.earth.org.uk/OperationTuneup/ ~GBP1 per household raw cost, everything done by the householders, I have 2nd/3rd round prototypes sitting on my desk still.
