The new boiler is in – a Worcester Bosch Ri. Guy showed up at 0810, and worked through to about 1400. Network cable was piped in properly this time (instead of my hack), new flue (plastic instead of metal) has been installed, and condensate drain now goes to the ground drain and not the soil stack. Still have to patch the soil stack closed.
The house is warm again, and I’m not burning 6 EUR of wood a day to keep it warm!
