How can I improve the airflow around my radiator?
You just need to make sure the radiator is unobstructed so that the air can flow freely around it (definitely no shelves and try to make sure that curtains are cut to hang higher than the top of the radiator and held flush against the wall). The issue of radiator boosters, or foil liners, also led to some hearty discussion.
How do you cool a room with a radiator in it?
2) Window against the wall below a single glazed window: The air rises above the radiator taking the cool air with it up to the top of the room, the warmer air starts to cool and falls down the opposite side of the room but there isn't cold air to drag into the centre of the room so it is more comfortable
How can I increase the efficiency of my heating system?
(For those with a "real fire", please read my previous article on that subject .) There are a number of ways to increase the efficiency of your system, ranging from bleeding radiators and installing radiator boosters, through to regularly maintaining the boiler. But just how much impact do each of these measures have?
Is DIY radiator insulation a good option?
DIY radiator insulation is a great option as you can make bespoke reflectors that perfectly fit your rads and making them couldn’t be simpler! Getting hold of a good quality reflective insulation is really all you need as many of these can be cut with scissors or a sharp blade, so no specialty tools are required.
Why are my radiators not getting very hot?
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.
How do I increase the heat of my radiator heater?
Open the wheel valve by turning it counterclockwise to provide more heat. To lessen the heat, shut down the valve by turning it clockwise.
What is a radiator booster?
The radiator booster is a long, light, rectangular piece of cheap-looking plastic that houses a small fan. The idea is to boost the efficiency of your radiator by dispersing the lovely warm air that gets trapped behind it. You plug the booster in and place it on top of your water-filled radiator.
Does putting tin foil behind radiators work?
Silver foil placed down the back of a radiator will reflect heat back into a room rather than letting it uselessly escape through the walls of a house. Do-it-yourself buffs suggest wrapping the foil round pieces of cardboard which have been cut to the right size to make it easier to fit.
Can you control radiator heat?
The thing about radiators is that they're either on or they're off—there's no in between and there's no way to adjust the temperature. Enter the thermostatic radiator valve, an add-on that can control the amount of heat emitted from a unit.
How do the dials on radiators work?
Radiator valves have numbers or symbols to represent how much heat the radiator is putting out. Normally, these numbers range from 1 – 6. Turning the valve to 3 should give you a room temperature around 20°C. Each number above or below then represents a single degree.
Clear them
The fastest and cheapest way to make sure your radiators are heating the room properly is to remove any objects on them or underneath them. That’s because radiators work on the principle that hot air rises, i.e., by natural convection. Cold air is drawn up the radiator at the bottom and rises out warm at the top.
Dust them
Dusting radiators will ensure that air passes through them as easily as possible. Large clumps of dust and lint can obstruct the vanes and reduce their efficiency.
Balancing them
If one room is always colder and/or its radiator takes a long time to heat up, it may be a good idea to balance the radiators.
Bleed them
If one radiator is cold at the top but hot at the bottom, it’s due to air trapped inside. The air basically occupies the space where hot water should be.
Make radiators hotter with radiator fans
Radiator fans are small electric fans that sit either on the top or the bottom of your radiator. By drawing air through the vanes of the radiator, they help it to emit as much heat as possible.
Removing radiator sludge
This may be particularly helpful if your radiator is hot at the top but cold at the bottom. The radiator can be isolated, removed from the wall, taken outside, and a garden hose can be connected to it for blasting out any sludge on the inside.
Make radiators hotter with a power flush
A power flush can give your radiators and heating system a massive efficiency boost.
What is the best insulation for radiators?
As we have discussed already, reflective foil insulations are used for making radiator reflectors and these are readily available from plenty of places online. However, not all foil insulations are created equal so be sure to opt for a high-quality brand (Such as Low-E Insulation) that will be effective and will last! Most importantly make sure to look for a material made with aluminium, not mylar as I mentioned above.
Why is it important to insulate behind radiators?
If you’re looking to cut down on costs of running your home but don’t want to make sacrifices in comfort, then insulating behind your radiators can be a quick, cost effective way of reducing heating bills whilst maintaining warmth.
How does foil insulation affect radiators?
Heat will always travel from a warm place to a cold so installing a reflective foil insulation behind your radiators will result in more heat being reflected into the room instead of being lost through the wall. Tests have shown an increase in the temperature output of over 5 degrees C, approx. 1 foot away from the radiator after a radiator shield has been installed.
Can you use a measuring tape to measure radiator insulation?
DIY radiator insulation is simple! No special tools are required and the Low-E Insulation that I used made no mess at all. You can use a measuring tape to measure your rads and cut the reflectors however I just held the insulation up against each radiator and marked the height and width on the foil.
Can radiator reflectors be used for radiators?
There are a few companies online selling radiator reflectors, some of which sell multi-packs of three or five etc to insulate a few of your rads. The issue with some of these is that they are standard size and not fit for your specific radiators, therefore they may have large areas exposed or may be too small. Also, the materials used for these can be very cheap and mostly ineffective. Many are made of a material cheap bubble wrap and/or mylar which is a foil coated plastic.
Can you use tinfoil behind radiators?
There are a few issues with using tinfoil beginning with the difficulty involved in getting such material behind the radiators. Tinfoil isn’t rigid enough to slide easily behind any radiators so you would need to remove them from the wall to get tinfoil installed. Also, tinfoil creases very easily and it looks terrible. So if the radiator is in an area where it is seen you want something more aesthetically pleasing.
Do radiators radiate heat?
Insulating a radiator may seem like a strange concept, however our radiators don’t just radiate heat internally, so any heat on the wall side can be lost through the wall and out of your home. In fact, 50% of the heat emitted from a radiator is direct at the wall and approximately 25% of is lost through the wall!
Why are radiators fitted under windows?
Bluespring kindly responded with the observation that "I heard somewhere that radiators are deliberately fitted under windows as the colder air just above helps to convect the hot air up and into the room, and colder air in the room swoops back toward the radiator, setting up a cycle of warm air in the room."
Is it better to leave a radiator on all day?
Leaving a radiator on all day is not efficient. We recommend getting to know your heating system and be aware of how long it takes to warm up and cool down your home. We have some great tips on our website to get the most out of your heating system.
Do radiator panels work?
Radiator panels do work, but we recommend the real deal, not just a bit of foil. You only need to put them behind radiators against heat loss ( external) walls, not internal walls. They work much better on solid walls and uninsulated cavity walls (but then these should be insulated).
Can you put a radiator in a double glazing room?
However, now that double glazing is quite prevalent, this isn't such a problem so radiators can be put in most places in the room. You just need to make sure the radiator is unobstructed so that the air can flow freely around it (definitely no shelves and try to make sure that curtains are cut to hang higher than the top of the radiator and held flush against the wall).
