It's a nightmare. Yesterday, the wife texted me, "The plumber is struggling to fit the radiator." How can you possibly have trouble putting a radiator back where one was removed? This morning, there was no heating! I'm no plumber, but I had an inkling of the issue. The idiot hadn't refilled the expansion tank. Once I topped it up, the heating burst into life; however, you could hear water filling up the radiator, so it would seem he hadn't bled the system.
Then, the Nest decided it was going to disconnect with the boiler, and they're a bugger to reconnect if your Nest and boiler are at the limit of the Bluetooth link. My parting words to the wife this morning were: "I'm so glad I'm going to work to escape this nightmare of a house!"
You don't want heating issues just as it turns cold. Our original boiler got condemned on a service in winter. Could use the immersion for water at least. Best to get it checked in warmer times.
We have a Nest and other half doesn't fully trust it. I think it does okay really and it's not had connection issues. She comes in and says the house is cold, but that could be due to her still being cold.
I love being able to tell Google to "Turn the temperature to twenty-one degrees." it reinforces my lazy git persona.
I replaced our boiler and six radiators about six years ago.
Comming in and saying it's cold My missus does that! Or gets out a nice warm bed and says: "It's hot in here!" 😱
