Thank you, will take a look at doing a blog time permitting! Re the advice above, the kiddie well on the way to mastering a long handled brush and will be put to work as soon as I see the first discarded cable tie! ?

@Thedreamer Good points, Can't go wrong with a tidy site. Same boat as you @Moonshine , 5 days a week and a toddler, but time at weekend and some flexibility at work (some). Site is 30mins drive away but agree, touching base with contractors regularly sounds V sensible. Even they can't read minds. @dnb Worth it in the end though right!?

Thank you all. Can't disagree with KISS in this case. Immersion heater via an iBoost (e.g) it is. Strange that more than one ASHP supplier is against the idea - Maybe they think it dilutes the business case for their kit.

One burning question on this: Similar to gc100, our ASHP supplier suggested diverting excess PV to the HW tank via the ASHP (instead of using an immersion heater) - therefore benefiting from the ASHPs increased efficiency (COP of 2+). This makes sense based on this fact alone, but would the ASHP produce a high enough temperature / Draw enough power to consume all of the excess PV generation? I believe the unit they're offering has a VFD so could ramp up/down based on supply from PV? Has anyone considered/attempted this? First question so hello as well! ?️

Hello, Learnt a lot from this site, and based a lot of our design decisions on the opinions of you all, so thank you and I hope to be able to contribute sometime soon. Plan to build a SIPs home for our young family in NW Scotland, hitting the ground running next year we hope. Managing contractors and doing a small amount of DIY along the way. Please watch this space for more questions! Thank you and keep up the great work.
