Most UK residents use a boiler as the heat source of their central heating systems. Fuel costs account for 75% of all the recurrent costs of using a boiler at home. Therefore, it makes sense to explore ways of improving the fuel efficiency of your LS1 Boilers.
Tune the burner
The efficiency of your burner depends on its ability to burn the fuel completely. If it is not getting enough oxygen, the fuel will not burn properly, leading to low efficiency. Too much air reduces efficiency because some of it is sent out unused as waste heat. Tuning the burner ensures that an optimal amount of air enters the system at all times.
Scrub the fireside
Your boiler may soot on the fireside section over time leading to energy loss. The soot insulates pipes reducing heat transfer and increasing fuel consumption. Studies indicate that a soot layer of 0.8mm reduces heat transfer by 10% while that of 4.5mm lowers heat transfer by 70%. This means that the temperature of your flue gas needs to be very high if it is to heat the water adequately.
LS1 Boilers that use solid fuels like biomass or coal are susceptible to fouling because of their high carbon content. Such systems need frequent scrubbing to maintain high efficiency. Reduce insulation by regularly cleaning the surfaces to ensure that they are free of soot. You can also improve their efficiency by installing a soot blower system on the fireside to remove the soot while the fuel is burning.
Descale the waterside
Over time, the waterside accumulates dirt and scale leading to reduced heat transfer. Experts opine that each millimeter of scale increases fuel usage by two percent. Scale forms due to water hardness or treatment with unsuitable chemicals.
Scale may also cause overheating that damages the Boiler leading to leaks and costly repairs. You can detect scale by looking at flue gas temperature since an increase in temperature indicates an increase in the scale on the heat-exchange surface. Removing the scale and mud legs or drums ensures that all the heat goes towards heating the water. This saves fuel.
If the water circulation in your heating system is inefficient, you can improve it by doing a powerflush. It involves attaching a pump and a flow reverser to the heating system so that the sludge and other dirt that has accumulated is swept away at high speed but low pressure. After that, a descaler is used to remove the limescale that has accumulated over the years. Some people also finish off with a corrosion inhibitor to prevent further rusting and sludge build up. Most experts recommend a powerflush every five years.
Using an economiser
An economiser is a system that taps waste heat in the flue gas and uses it to heat the cold water entering the boiler. It raises the temperature of feed water and reduces the damage caused by cold water. Economisers are valuable for home improvement in residences with central heating because the waste heat warms the air, eliminating the need for extra heating.
The insulation jacket
The insulation jacket is a cover you fit round your LSI boilers and pipework such that they do not lose heat to the surroundings. It reduces heat loss through the surface by up to 75%. The water heats up fast and remains hot for a long period reducing the need to reheat after a few hours.
You can enhance the energy efficiency of your boiler by converting your residence into a smart home. Smart homes are connected to smart thermostats such that you can manage the heating system remotely through an app installed on your phone. The smart devices are especially effective in central heating systems because they ensure the entire home is heated to the desired temperature.
All you need to do is install a control panel and connect it to the boiler. Then link it to the thermostat through a hotspot or wifi. Download the app on your phone or tablet so that you can control the heating system remotely. Smart thermostats are suitable for home improvement in residences with system and combination boilers. They allow you to track energy consumption in your home and save on energy bills.
If your boiler utilizes steam systems, heat loss can occur through steam and water leakages. Reduce steam losses by ensuring that the pipework is of the right dimension and free of leakages. Replace all the old pipes and replace all the leaking joints and valves.
Turn on idle heating systems
Ensure that your boiler is active even during the hot summer months because it may break down due to inactivity. Switch it at least once every week for just 30 minutes to ensure that all systems are working properly.
