Lithium storage batteries

In 2015 I installed lithium storage batteries so that I could use even more of the electricity generated by my solar PV panels; see this info sheet for details ( this is now oldish - note that the price of storage batteries has gone down, and technology up, since this was written). Here's a recording of an excellent Zoom session organised in 2021 by Transition Town Lewes about solar PV and storage batteries

Air source heat pump

In 2021 I had an air source heat pump installed, to replace my old combi boiler for heating and hot water. Here's an account of how I'm finding it.
And here again is a recording of a Zoom session organised in 2021 by Transition Town Lewes about air source heat pumps and other alternatives to gas boilers.
