I know central heating isn’t quite as exciting as tablets and smartphones, but after my boiler packed up yet again it’s worth mentioning this: if you have an Ideal Isar boiler and don’t pay for British Gas HomeCare-style cover, you really should.
My one’s suffered from electrode failures (twice), some internal gubbins going wrong (three times) and this time, the failure of the heat exchanger (again) and circuit board; it’s seven years old and it’s been breaking down at least once a year for the last four years. Each time, the gas engineers tell me that the Isar is far and away the most unreliable and problem-prone boiler they deal with – and each time, the boiler cover saves me from a frighteningly expensive repair bill. If you’ve got one, make sure it’s covered.
