Boiler trouble

This week we have had to have our boiler fixed. It is quite an important device in the house, as it supplies the hot water and heating. Now that the weather is getting colder outside it's important to keep warm inside. The engineer came last Saturday and replaced several parts for us, thinking it would solve the problem. However, after about a day and a half we realised the problem had not been fixed. The water was cold in the mornings and the heating wasn't coming on. So next time he came the same engineer was a bit puzzled at first but then eventually found the culprit - a small loose resistor on the ignition circuit board. Thankfully he was able to fix and be on his way in less than an hour. So, the house is warmer than it's been for a while - I'm not sure that it was working as it should last year you know, it might have been something that has progressively been getting worse. Our house is now toastie warm. It's great! It's just a shame that the energy companies have all put their prices up :-(
