Graham Hendra’s e-book is out on Kindle
@grahamh @editor
I've read the book and have to say it's excellent for what it is. It is exactly as Graham describes it, "i wrote the book for homeowners, it answers all the simple questions like, how big is a heat pump, can it go in the loft etc." and as such it is an excellent read for any homeowner considering the option of installing a heat pump.
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.
I bought the actual book direct from Graham as I closed my Amazon account some time ago.
Useful intro - I look forward to part 2, the engineers cut.

Purchased.... although from Amazon as I've been rushing around like a lunatic all weekend and Amazon was a couple of finger clicks and I pay for Prime so I'm darn well going to get my money's worth 😀
Off grid on the isle of purbeck
2.4kW solar, 15kWh Seplos Mason, Outback power systems 3kW inverter/charger, solid fuel heating with air/air for shoulder months, 10 acres of heathland/woods.
My wife’s house: 1946 3 bed end of terrace in Somerset, ASHP with rads + UFH, triple glazed, retrofit IWI in troublesome rooms, small rear extension.
Amazon just delivered, some good content, but the typesetting and layout needs a bit of work if there's a second revision planned.
