Why does my boiler come on in the middle of the night?
It’s true that boilers do turn on from time to time during the night. With a system or heat only boiler, it’s the cylinder that gets heated up when its temperature drops and the thermostat tells the boiler to fire up (assuming it’s not on a timer). Many people don’t really use much hot water from the tap, either.
Why does my heating come on when it’s switched off?
A check valve is used to stop the natural convection from warming up your home when your heating is switched off. If the check valve is broken or blocked, heat will rise through your system causing your radiators to stay hot. Once again, contact a qualified professional to come and check what the problem is.
Is it more efficient to leave heating on overnight?
According to experts at the Energy Saving Trust, the idea it’s cheaper to leave the heating on low all day is a myth. The Energy Saving Trust says if you’re keeping the heating on all day you’re losing energy all day, so it’s better to heat your home only when you need it.
Why is my immersion boiler not running overnight?
Many thanks, Alec. If its a dual element set up then its most likely that the overnight (larger of the two elements in the tank) element has gone and needs replacing. If its a single element set up, then it points towards the timeclock being faulty and not switching the supply on to energise the element during the off peak period overnight.
Where is the off peak switch on a boiler?
The off peak will be wired to the lower element. Leave it on and let it heat up over night. If you need a boost during the day turn the other switch on for a bit. Very common set up. Click to expand…
What’s the best time to turn off the boiler?
All modern boilers come with a timer on them, usually on a separate panel that’s wired up to the boiler itself. You can set the on and off times for every day of the week. So, you can set it to switch off at, say, 11 p.m. every night and come on at 7 a.m. every weekday (and 8 a.m. at weekends).
Why does my boiler need to be on all the time?
This basically means that your boiler will make sure that the water in your pipes is flowing and that the temperature of the water will not drop below zero. This protects your pipes from cracking and your boiler from breaking down. This can only happen if your boiler is switched on!

What happens if you turn your boiler off in the winter?
This means that any water in your central heating pipes is at risk of freezing. When water freezes it expands, and if the water has nowhere to expand into, like in a central heating system, it will cause damage to pipes and in worst-case scenarios, your boiler. Most boilers have a winter setting.

Do you turn on your boiler at night?
It’s true that boilers do turn on from time to time during the night. Combi boilers work best when the heat exchanger inside is kept warm, so it will need “topping up” a few times overnight to make sure you have instant hot water when you need it.
