Can I heat hot water and radiators at the same time?
How do combi boilers work? Combi boilers provide a combination of instantaneous hot water and effective central heating.Therefore, the system will either transport hot water to your radiators or to your hot water tap however, this will not be done at the same time and the hot water circuit usually takes priority.
Do you bleed a radiator when it is on or off?
Turn off your heating. You can’t bleed a radiator when the heating is on, as it may be too hot to touch. You could also get hot water spraying out of the radiator. Use your radiator key to turn the valve at the top of the radiator.

Are radiators bad for your health?
Can radiators impact respiratory health? Although radiators are effective at heating up a room, they can also impact your respiratory health. Radiators heat the air in a room and as the air warms up, it rises in a process known as convection. This causes the air to move, which can circulate dust around the room.
Do radiators heat from top to bottom?
Radiators are naturally warmer on top than the bottom, but some radiators more than others. For example, ‘convection radiators’ focus on convection heating which is when heat rises and pushes cool air downwards. This cool air is then heated and the cycle continues.
Why are radiators under windows?
Windows are traditionally the worst insulated surfaces in a building shell.In the twentieth century, to combat that cold feeling and keep the room comfortably warm, radiators were always placed under a window. The rising heat of the radiator forms a kind of hot air curtain that shields you from the cold air.
Why do we need 12 degrees when balancing radiators?
Then on the other side of the radiator check the temperature of the pipe leading into the secondary valve or TRV. The goal is to achieve a temperature difference between the two figures of 12 degrees where the lockshield valve temperature is 12 degrees higher than the exit valve’s temperature.
What does balancing a radiator mean?
Balancing radiators means adjusting the radiator valves to level the water flow and make sure your radiators heat up at the same speed.
