How to use the online alarm clock
As you hand responsibility for meeting the gas boiler engineer to a housemate or colleague, set the alarm for 3:15 pm so the changeover is not lost among afternoon jobs. That gives them a clear cue to listen for the door and have access to the boiler ready. If the visit runs late, 4:00 pm is a sensible point for the next person to review who is still available.
A boiler appointment can be missed if the alarm page is left in the background and the browser limits what it can do there. Keep the page active where practical and check that sound is allowed before relying on the alert. The alarm will not sound if the browser has been closed or the phone or computer has gone to sleep, so the engineer handover needs a separate reminder when nobody will keep the screen awake.
Once someone else is covering the afternoon visit, leave the boiler area accessible without making the room uncomfortable. At 3:15 pm, a warm spell can make strong air conditioning tempting, but a very cool room beside outdoor heat may be awkward for anyone moving tools in and out. A moderate setting, with internal doors positioned sensibly, keeps the route usable while avoiding a blast of cold air around the inspection space.
Common questions
Does the alarm still work if I close the tab?
No. Everything runs inside this page, so closing the tab — or quitting the browser altogether — ends the countdown there and then. Leaving it open in the background is all it asks, and switching to another tab makes no difference.
What happens if my laptop goes to sleep before 3:15 pm?
The tab sleeps along with it and the alarm will not sound on time, if at all. If you are relying on it, change the power settings so the machine stays awake, or keep a phone alarm running as well.
Do I need an account or an app?
Neither. Choose a time and a sound, press Start, and it runs in this browser tab. Nothing is downloaded, nothing is registered, and closing the page leaves nothing behind on the device.
Can I change the sound?
Yes, there is a short list of tones to pick from before you press Start. Softer sounds are easy to sleep through, so a firmer bell tends to be the safer choice for anything early in the morning.
