Guys came back today to finish off the lagging and tidy up a few areas. Changed out the expansion tank from 18l to 25l. Not really a lot else to see except the services cupboard with all the meters and what not

Boiler cupboard (boiler doesn't work anymore!) - quite messy with old and new pipework. Anything unlagged is old (I assume?!)

Looks good. Why did you keep the boiler?

Just left it for the time being. I'll probably get rid next year after we've had the winter. It's all disconnected and just a lump on the wall for the moment

Solic now replaced - all working and diverting now. A bit of extra free energy for the tank
