Sharing is caring!
Thankfully, the beginning of winter is mild, but with the recent increase in natural gas prices and without any signs of cheapness, many of us are looking for ways to reduce bills by improving the efficiency of home heating.
Generally speaking, there are many things you can do to improve the overall performance of the radiator.
Most of the efficiency comes from the boiler itself; the efficiency of modern condensing boilers can reach 90%, while the efficiency of older non-condensing boilers may be less than 60%.Can also make some improvements OpenTherm The equipped boiler connects the central gas heating boiler with the indoor thermostat so that they can optimize the output temperature, not just on/off.
Therefore, if you need a new boiler, the OpenTherm condensing boiler will be a good investment, but I don’t recommend everyone to go out and buy a new boiler.
You can make some small improvements to increase the heating efficiency. Some recommendations have limited data to support these claims, and these recommendations are not a panacea for saving money.
Radiator and central heating maintenance
A simple, cheap or free way to improve performance is to vent the radiator to remove any air trapped on the top of the radiator. If the top of the heat sink is not too hot compared to the bottom, you can usually tell if you need to do this.
Over time, your central heating system will become clogged with sludge and rust, so it is wise to flush the system. However, it only needs to be done every few years.
The radiator can be flushed manually, but the engineer needs to complete the entire system.
MagnaClean filter + MagnaCleanse
To reduce the need for flushing and improve performance, you can install a MagnaClean filter to filter out the iron oxide sludge (rust) that accumulates inside the radiator. After installing the filter, you can use MagnaCleanse to remove all existing sludge in the system.
The company claims that using it can make the radiator easier to heat, and can reduce energy costs by up to 6% per year on average. Due to the reduction of sludge in the system, failures have been reduced by 30%, and annual/household emissions have been reduced by 200-300 kg.
Improve radiator performance and efficiency
If your radiator is in a traditional location under the window, you need to make sure that the curtains do not obstruct the air flow. This is an obvious suggestion, but it will have a huge impact.
Radiator foil insulator
If the radiator is located on an external wall, it is usually recommended to lay foil on the wall behind the radiator to reduce heat loss through the cold wall. The impact of using kitchen foil may be small, but you can buy a suitable foil insulation paper roll, which should provide better performance. There are many well-reviewed options on Amazon.
Radiator fan and booster
Radiator fans or boosters are a controversial topic. As you might expect, all brands that sell these products claim to save a lot of money.
When i look back Speedcomfort radiator fan, They claim an increase of 22%, but there seems to be no science to support this claim.
Competing brand Radfan has worked with Salford University to test a similar system and found that energy consumption has been reduced by 5%.
Although you cannot increase the efficiency of the radiator itself, the logic seems to be that these devices can better circulate warm air and reduce the amount of hot air that stays at the ceiling level, where you can’t feel it. Since this warm air will not be trapped at the top of the room, at least, it should mean that you can feel the heating effect faster, so it means you don’t need to warm up the room for a long time.
Radfan claims to have a better design, their products can guide the air horizontally, while SpeedFan and other products accelerate the air flow upwards.
Programmable intelligent thermostatic radiator valve and intelligent thermostat
I have an entire article dedicated to Smart TRVHowever, for many households, these may be some of the best ways to reduce heating costs, but the upfront costs are high.
The normal thermostatic radiator valve closes every time it heats up. But programmable allows you to heat different rooms at different times. In the morning, you may want the bedroom to stay warm when you wake up, but you don’t want to worry about the living area. Conversely, you may like a cool bedroom when you sleep, but you need a warm living area at night.
I have been working from home for many years and this is becoming more and more popular, so being able to heat my office during the day instead of other parts of the house has a huge impact on our heating costs.
All smart TRVs work best when used with smart thermostats and boiler controls, which is how most of them are sold. This may be a fairly expensive upfront investment, but it should provide a positive long-term investment.
