What about domestic boiler?
Same old story..... Heatings been off all
Either way a gas boiler system should be maintained ever year.
I can add a bit to this, being it’s what I do for a living.
• Test running the heating early is a good idea so that you know it’s going to work when it’s properly required. Motorised valves have a tendency to stick & the lack of use over the summer can make this a common cause. Likewise for the Diverter Valve inside the boiler if you own a Combi. Run the heating up here & there & you’ll be in good stead when it gets cold enough to call upon it.
• If you’re on a pressurised system & notice you’re low on pressure (& know how to top it up), then do so (to 1bar or just over). But if having to do so becomes a regular occurrence, then have someone check out the cause. A small leak or an expansion vessel needing a recharge will be the likely culprit.
• Change the batteries on your Room Stat.
• Having the boiler serviced before the winter months is best practice. You’ll hopefully be able to pick up on anything brewing, before it manifests itself as a full blown problem, which will almost certainly occur on Christmas Eve or the first sub zero evening.
• A service & a breakdown are two separate things. If the boiler breaks down it might need a service as well as the repair, but don’t assume the service will cure the problem. You wouldn’t pull over on the side of the Dual Carriageway with smoke pouring from the bonnet & proceed to immediately book the car in for a service. Same applies.
• Last one R.E servicing: If your boiler is within it’s manufacturer guarantee period, that guarantee is only good if you’ve got a FSH. They won’t entertain it if you’ve not had it annually maintained.
• If you’re lucky enough to be able to escape England for some Winter Sun, turn off your Stopcock & open the taps before you go. I’ve seen some absolutely devastating property damage caused by frozen pipework in empty houses over the years.
• Isolate your outside tap when not in use. Don’t forget to open it to drain any residual water sat inside it.
I’m sure there’s loads more I haven’t thought about. As said before, my PM’s are always open if anyone has any Plumbing/Heating related issues or questions they’d like an opinion on. Least I can do considering the free information I’ve sponged from everyone else over the last year & a bit.
