heating and boiler problems – lovekin.net
Since it's difficult to remember all the details of central heating problems and gas boiler problems we deal with, we decided to keep this log of some of the problems and how we've attempted to sort them out. Putting this information online allows other people to look for clues and ideas. Too often gas service engineers and central heating engineers lack backup and support and we find ourselves trying to re-invent the wheel. That's particularly true for small companies.
There are lots of skilled people out there and we'd like your ideas. If we've got something wrong or you can improve on what we've done please contact us. Or if you've sorted out problems and want to share how, we may be able to add your ideas. I’m Paul and you can email me: admin@boilerservices.net
We're sorry we can't deal with individual queries about boiler and heating problems. We just haven't enough time. We're thinking about the possibility of running a forum in the future though, where individual questions can be posted, but we're not there yet!
