@transparent Life is not so complicated (or sometimes depressing) at that age! Toodles.

Yesterday afternoon I was drilling a 'blind' hole through a floor joist to take an electrical cable which needed re-routing.
Not only was I drilling without being able to see the other side of that joist,
but I'd also only lifted one floorboard, just to safe time, and couldn't see the drill itself.
Suddenly the drill jammed and curls of smoke wafted upwards into the room.
Had I cut into an unseen electrical cable?
Had this ignited the dry wood of the joist?
Unable to retract the drill bit by reversing direction, I shoved my head below floor-board level to see what was happening.
... Great relief.
It was only the drill on fire! 😥

Retrofitted 11.2kw Mitsubishi Ecodan to new radiators commissioned November 2021.
14 x 500w Monocrystalline solar panels.
2 ESS Smile G3 10.1 batteries.
ESS Smile G3 5kw inverter.

Our solar hot water is now 2C above the set temperature the pump got it to at 1pm. Thats the upside. But solar PV, nominal 6kW was generating 5.6 at noon a few days ago and today because it is so much warmer the max is 4.7kW!
2kW + Growatt & 4kW +Sunnyboy PV on south-facing roof Solar thermal. 9.5kWh Givenergy battery with AC3. MVHR. Vaillant 7kW ASHP (very pleased with SCOP 4.7) open system operating on WC
@judith Our peak is 5.4 kWp today and so far (16:35) we have seen solar production of 32.2 kWh from our 8.1kWp setup. (Today has been the most productive day this month so far) and the total for March 2023 was 390.7kWh and for March 2024, it was 436.6, so far this March we have 615.3 kWh. Keep improving I say! Rewards, Toodles.🌞

Renewable Heating Hub is today introducing a new measure to address a glaring trade imbalance between UK homeowners and heat pump installers.
As of today, all heat pump installers operating within the UK will be subject to a 63% tariff, calculated using our new “Fair & Reciprocal Installer Disparity Model™."
This model is based on a simple but effective formula: Total homeowner frustration ÷ average installer accountability × installer competence.
This tariff is necessary to rebalance the vast consumer deficit that has emerged as homeowners fork out thousands for renewable heating systems, only to receive baffling heat loss calculations, undersized pumps and a general sense of abandonment once payment clears.
Furthermore, the deficit is so lopsided that all the money flows one way (from the homeowner to the installer) with zero return value in many cases. This imbalance is only propped up by the Boiler Upgrade Scheme (BUS), which effectively acts as a government subsidy to keep the deficit from collapsing entirely.
We must act decisively in the face of this one-sided arrangement. Homeowners deserve recourse. They deserve resolution.
Installers who feel unfairly targeted by this move may apply for a “Tariff Waiver” by providing evidence of flawless commissioning sheets, clear MCS documentation, and at least three unsolicited homeowner thank-you cards. A photo of a well-lagged flow and return pipe won’t hurt either. This will allow them to negotiate their tariff, with the possibility of a reduced rate; especially if they agree to advertise on the website or sponsor our podcast, which we now officially recognise as valid forms of reparations.

Excellent proposal @editor
But I do wonder whether this might set a questionable president.
What happens, for instance, when a customer complains that the installer has configured a flow which is too fast,
but the installer had based the quotation on the customer's request for a high rate of return? 🤔

@transparent very good!

@transparent I think one would just have to go with the flow!
