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, which although is made for Worcester boilers, is actually really useful for most makes of boilers:

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 I’ll run you through how to set a timer on a boiler:

First, ignore all the little tabs for now, and set the clock to the right time. You do this by turning the dial round 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 1:30pm (13:30 in 24 hour clock speak) then you want the arrow to be halfway between 13 and 14.

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 aren’t as confusing as they look: they just represent a 15 minute period of time, and are pushed in to select when you want the boiler to turn on. 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 6:30am and 8am, you are going to want to push in all of the tabs that represent that time – so you should have all 6 consecutive tabs pushed down between 6:30am and 8am. All of the other tabs should be 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!

Here’s my boiler timer.  The time is currently 1pm so the arrow points to 1pm, and the timer is set to come on twice in a day – between 5:45am and 7:30am (we are early birds!) and between 6pm and 8pm.  If you look closely you’ll notice the tabs are down at these times, and all of the other tabs are up.

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 (depending on your boiler – mine’s a stopwatch) and your boiler should now come on at the desired times!

Some tips on setting your boiler: it typically takes about half an hour for a house to warm up once you’ve switched your boiler on, and around half an hour to cool down again once it’s switched off. So with that in mind, if you get up at 7:30am and leave the house at 8.30am, it’s most energy efficient and comfortable for you if you set your timer to come on at 7am and off at 8am.

Smartphone controlled central heating sounds positively space-age, doesn’t it?  Yet Honeywell, heating control specialists, have created just that with their evohome intelligent heating system.

Evohome connects to your boiler and existing radiators and allow you to control your entire heating system via a wireless central console or smartphone app.  This allows you to control the heating room-by-room.  I’m quite bad at adjusting my thermostats – I just turn on my heating and that’s that – but Honeywell’s Jeremy Paterson makes a great point when he says “In the same way you don’t only have one light switch for your entire house, we believe you shouldn’t control your heating with one single switch“:

Thinking about it, my daughter is often tucked up warm and cosy in bed, while we’re freezing in the living room.  Not wanting to go in and risk waking her to turn her radiator thermostat down so we can have the heating on in the living room without cooking her in her tiny bedroom, we’d really benefit from being able to adjust her radiator via smartphone controlled central heating.

Even if you don’t have young kids, perhaps you have some rooms that don’t need to be heated, or have smaller rooms that require less heating than the larger rooms?  Or maybe you sensibly want to heat your hall less than your main rooms?  Instead of having to go round and adjust all of your radiator thermostats you can just sit on your sofa and adjust the heating with the touch of a button (saving energy in more ways than one!).


For me, the absolute best thing about Evohome and their smartphone controlled central heating is that you can also control your heating when you are away from home.  In winter I hate coming home to a freezing cold house, so I like to set the timer for 20 minutes before I’m due home so the house is warm and cosy for my return.  Which works great some of the time, but then there are other times when my heating is on and I’ve been stuck in a traffic jam, or had to unexpectedly work late, or (before I became a parent!) had impromptu nights out straight after work, causing me to unnecessarily waste energy.  With evohome you can just use your iOS or android smartphone and switch your heating off.  Genius!

Honeywell say the evohome system can save you up to 40% on your heating bills, which is a pretty hefty saving.  The evohome pack, which is guaranteed to fit most heating systems, including those with stored hot water, will be available for purchase in the UK in January 2014.  Priced from £249, it should soon pay for itself in energy savings.  Smartphone controlled central heating?  I’m definitely in!
