The boiler is installed and working! It has left me feeling somewhat lighter in the bank account but I think it will be worth it. We are certainly having to run far less water to get the hot taps to live up to their name. I’m also impressed with the new thermostat. It looked a bit plasticky in the photos but turns out to be impressively weighty and pretty easy to program. A good job to have done now that winter continues to draw on.
