The way combis work (and some older boilers) is that when the boiler heats up to make instant hot water it (the boiler) gets hot. You turn the tap off and the boiler still has lots of heat so it needs to dump that heat and uses the one mandatory open radiator to cool the boiler.
Is it OK to turn off some radiators?
You will almost certainly be able to save money by turning your radiators off in individual rooms that are not in use. It’s a waste of money and energy to be heating unused spaces. Also, close the doors to any unheated rooms to help stop the warm air from the heated rooms or spaces escaping into the colder ones.

Can you turn off 1 radiator?
Radiators, whether they’re 1-pipe or 2-pipe systems, are easy to turn off with the turn of just a few valves.
Why do some radiators come on and not others?
Check for Trapped Air and Bleed Your Radiators
If just one (or a few) of your radiators aren’t heating up, the most common reason for this is trapped air. If you’ve just turned the heating back on after the summer, air can become trapped in your radiators, causing them to be warm at the bottom but cold at the top.

Where is the diverter valve located?
It’s usually a lever that’s situated behind the bath taps that you can pull up or push down. System and conventional boilers don’t require a diverter valve. This is because the hot water they produce is stored in a hot water cylinder.
Why is my heating not turning off?

Do radiator thermostats save money?
Can you save money by using TRVs? TRVs can save you money because they allow you to heat your home more efficiently and in a smart way that is appropriate to each area of the home.This means that radiators don’t produce unnecessary heat.
Why is 1 radiator in my house cold?

What is the quickest way to balance your radiators?
How To Balance Radiators
- Turn off your heating.
- Open all radiator valves.
- Note the speed each radiator heats up.
- Allow your heating to cool down.
- Turn your heating back on.
- Adjust the fastest radiator.
- Repeat for other radiators.
Why are some radiators hotter than others?
Some radiators occationally get quite a bit warmer than others. When this happens it usually means that your central heating system is out of balance.If your heating system is not balanced then the radiators that are closest to the boiler or heating source may get a lot more heat than those that are further away.
What happens if you don’t bleed radiators?
If you don’t bleed your radiators, the issue will worsen over time. It could lead to your central heating eventually not being capable of reaching your preferred temperature, even when turned up to the max.

Once you’ve bled all the downstairs radiators you move on to the upstairs, again beginning with the radiator which is furthest from the boiler.
Does putting tin foil behind radiators work?
Harris reports that “reductions in the overall energy consumption of the [test] room of up to 6% were recorded by installing [plain] foil behind a radiator, while the heat loss through the area of wall immediately behind the radiator fell to less than 30% of the original value”.
Is it cheaper to leave your thermostat at one temperature?
Says the U.S. Department of Energy on energy.gov, “You can easily save energy in the winter by setting the thermostat to 68 degrees while you’re awake and setting it lower while you’re asleep or away from home.” Figure you save up to 1 percent per year on your heating bill for each degree you set back the thermostat
Does turning the heat on and off raise the bill?

What are the two valves on a radiator for?
One valve accounts for the amount of hot water that enters the radiator. The other valve, referred to as the lockshield valve, balances the system by regulating how much heat the radiator gives off.
