Let me show you how to set a timer on a boiler.
I’ve written about setting the timer on your boiler in the past. But the other day it dawned on me: what if you don’t know how to set a timer?
I have a combi boiler and it has one of those mechanical timers on it. Being used to digital timers I’ll admit I was a little flummoxed by it when we first moved into our house. I did a bit of internet searching and found this useful video. Although is made for Worcester boilers, is actually really useful for most makes of boilers:
How to set your boiler timer
Here’s a link to the video if you can’t see it – here.
If you can’t get the video to work, or want a step by step guide, then I’ll run you through how to set a timer on a boiler:
1. Set the time on your boiler
First, ignore all the little tabs for now, and set the clock to the right time.
You can do this by turning the dial around clockwise until the arrow points to the correct time in the outer portion of the dial. It’s important to bear in mind that boilers work on the 24-hour clock. So make sure you’ve set it to 24 hour clock time, otherwise, your heating will come out at odd hours of the night! If it’s 1:30 pm (13:30 in 24-hour clock speak) then you want the arrow to be halfway between the 13 and 14.
2. Now set the time when you want your boiler to come on
Once the time is set, you can now set the times that you would like your heating to come on and go off at.
This is where the little tabs come in. These tabs can be overwhelming as there are so many, but I promise they aren’t as confusing as they look. They just represent a 15 minute period of time. You simply push them in to select what time you want the boiler to turn on. Let me talk you through this, in case this sounds complicated.
With the time set properly, you’ll notice that each tab lines up with each 15-minute segment of the 24-hour clock. So, to tell your boiler that you want your heating to come on between 5:45 am and 7:30 am, you are going to want to push in all of the tabs that represent that time – so you should have all 7 consecutive tabs pushed down between 5:45 am and 7:30 am. All of the other tabs should be up.
Here’s a picture of my boiler timer so you can see what I mean.
The time is currently 1 pm so the arrow points to 1 pm. The heating is set to come on twice a day. Firstly between 5:45 am and 7:30 am (we are early birds!). And secondly between 6 pm and 8 pm. If you look closely you’ll notice the tabs are down at these times, and all of the other tabs are up.
It’s quite easy to accidentally twist the dial and change the time when you’re adjusting the tabs, so you may have to readjust the time at this stage!
3. Next Steps
Now all you have to do is turn the switch that you would normally switch the boiler on with to point to the picture of a clock or stopwatch. It will depend on your boiler – mine’s a stopwatch. Your boiler should now come on at the desired times! And that’s how to set a timer on a boiler!
Energy Efficiency Tips
I always love a two for one deal, so let me share with you my top energy efficiency tip for your boiler.
It typically takes about half an hour for your house to warm up once you’ve switched your boiler on. It then takes around half an hour for your house to cool down again once it’s switched off. So, with that in mind, if you get up at 7:30 am and leave the house at 8.30 am, it’s most energy-efficient and comfortable for you if you set your boiler timer for your heating to come on at 7 am and off at 8 am.
