Boiler and Central Heating Service

Heating system efficiency depends mostly on carrying out regular services and repairing any faults/leaks as soon as they occur, that’s why it’s important not to forget about this. Central heating system services should be carried out favorably in summer so that there won’t be any problems with heating during colder seasons and winter.

What should be checked?

Boiler and central heating service include:
Checking the ventilation in the boiler/plant room – this should always be the first thing carried out during a service as most serious problems regarding the exploitation of heating appliances are caused by inadequate ventilation. In some cases, it can even lead to CO2 (Carbon Monoxide) escaping and poisoning the household, that’s why it’s important to check whether the boiler/plant room has adequate ventilation.

What is Boiler Service All About?

Most importantly, it’s there cleaning, leak checks, and checking the safety of the device. How frequently a service has to be carried out depends on the boiler power (kW) and their make, as well as a type of fuel used. Boiler cleaning means the removal of any dirt from the inside of heat exchanger.
The frequency of the need to clean the boiler should be checked in the technical documents of the device, provided by the manufacturer. Solid fuel boilers are the ones that need most frequent cleaning, while gas boilers require the least frequent cleaning.
Boiler service is the cleaning of a heat exchanger, condensate trap, the setting of gas valve (ratio CO/CO2) and burner pressure, checking flue, and operation of a safety device.
Power flushing has to be carried out every 5 years as sludge accumulates inside the boiler and central heating. Its removal will improve the efficiency of those devices and reduce bills, as well as increasing the boiler’s lifespan.
Boiler service must be carried out by a qualified plumber (gas engineer), if it’s carried out by someone without the right qualifications then it can result in damages to the appliance. Even cleaning the burner is not easy as it requires the knowledge of how to handle the parts as they can be easily damaged.
Furthermore, wiring connection and the pump must be checked. It’s worth noting that all pumps can cause problems if not used for a long time as dirt in the water accumulates and can stop the pump from working.
While carrying out boiler service, after turning on the appliance, the difference between flow and return must be checked, making sure that it’s not above 10 C. It it’s greater, then it means that not enough flow in the boiler, which can be caused by a dirty filter or heat exchanger, or a fault in the pump.
Pressure should be checked to make sure that it’s between 0.8 and 1.6bar. If it’s lower, the system needs to be filled to the correct pressure. Low pressure might be the result of leaks, that’s why it’s necessary to check all previous areas where leakages occurred and places where such faults can occur.
Expansion vessel must be checked to make sure that it has the right pressure and that the membrane is not damaged.
Relief valve (safety valve) check must be performed to see if it is working correctly and not leaking. If there are any problems with it then it should be cleaned or replaced straight away.

Frequent Plumbing Problems in our House

Clogged Drain

Plumbing problems arise in every household. These can happen due to an old age of the pipe installation or the job not being properly done by a plumber during house renovation. The clogged drain is the most common problem, especially in sink, basin, toilets, baths, as well as showers. Wrongly fitted drain pipes by the plumber is a common problem of a drain pipe blockage. Other causes for blocked drain pipes are as follows: too small pipe diameter, small flow, or sharp bends.

You can try to unclog the drain by yourself by the use of chemicals intended for the job, e.g. caustic soda, one shot, or you can use a spring spiral. Remember, if you are unable to do the job yourself then call an emergency plumber as, if not done properly, it can cause more serious problems such as flooding of the house, and result in even bigger costs. Romford Emergency Plumber will be able to do this job for you professionally and safely.

Leaking Tap

leaking tap is one of the most frustrating problems as it means that we have to pay bigger water bills. The cause of it can be minimal, such as a loose gasket. However, sometimes the cause can be more complicated, requiring an emergency plumber attending the job. Sometimes it may be necessary to buy a new tap.

Radiator Bleeding

A radiator may need bleeding if it’s cold at the top and warm at the bottom, meaning that it will have problems heating up the room, can result in dampness, and awful smells. It is worth remembering that the BTU of radiators is chosen according to the room size, meaning that it should heat up the whole room. An emergency plumber must be called in order to bleed a radiator as it’s a dangerous job and can result in burns and house flooding. After, or during radiator bleeding, water pressure must be filled up to seal in the central heating system, this is done automatically in vented systems.

Emergency Leaks

Fractured water pipes in walls or floors can result in expensive repairs. An emergency plumber must be called in such cases as they will arrive in minutes after the call. It’s not easy to locate the origin of the leak, especially when the whole wall or floor becomes wet from the leak. Sometimes it is necessary to fix a completely new pipe installation (which can mean huge repairs), it’s also worth remembering that a damp or wet wall can be the result of a much smaller problem, such as a screw or nail in the pipe, or lack of insulation (resulting in condensation).

Boiler

A boiler is the most important appliance in our house, it heats up the water, as well as the central heating, underfloor heating, and heats up our house. For a boiler to work efficiently and safely, we have to perform a service on it every year, however, this does not mean that it will work without any problems. Sometimes it may be necessary to install a new boiler as a repair will be too costly and not worth it. In case of a boiler break down, we can’t repair it ourselves as it is a gas installation and requires professional qualifications and knowledge. During the burning of gas, an odourless and poisonous gas (CO2) is let out, meaning that in order to repair or service a boiler we must call a qualified and registered gas engineer in Romford with the right qualifications, who will service or repair the boiler according to the Gas Safe regulations, as well as perform a gas safety check in our house.

Trying to perform any repairs by yourself can result in worsening the problem and making it more expensive to repair, so sometimes it’s better to call an emergency plumber in Romford to take care of the job for us, who will repair any problem quickly, professionally, and safely.

A Plumber or a Gas Engineer?

Who do we need for our plumging problem? A gas engineer or a plumber? That’s the question that each one of us asks when there’s a problem with our central heating, boiler issues, clogged drain, or a leak.

When will a plumber be useful?

plumber in Romford will repair any leak, unclog a drain, take care of any problems with the central heating system, as well as any water appliances in your house, such as: unvented hot water cylinder, vented cylinder, water cylinder, and etc. In order for a plumber to undertake some jobs, he/she must have the right qualifications in order to ensure our safety. Those jobs include unvented water cylinder, disinfection of water installation, as well as all water pressure installations.

How about a gas engineer?

We’ll need a gas engineer in Romford in order to undertake any repairs or fix any gas appliances such as a boiler, fireplace, water heaters, hob, heaters, etc. A gas engineer is a highly qualified and experienced plumber, who can take care of any problems regarding plumbing in your house. A gas engineer will also charge more than a plumber, however, for those prices, we can be certain of our safety and that his/her job has been done according to Gas Safe and building regulations, which is what we usually want.

A System Boiler or Combi?

What boiler would be the best for your house in Romford?

A system boiler is one that heats the central heating system, while a combi boiler is one that also heats up the water which flows to your taps. A system boiler does not heat up the water, meaning that an unvented hot water cylinder must be connected to it which is essentially a hot water tank.

A combi boiler heats up the water as it flows, meaning that it begins to heat up the water as soon as you turn the hot water on.

Both boilers, system and combi, are chosen according to the requirements of your house (depending on its size).

Combi boilers are usually intended for smaller houses in Romford, where the bathroom, kitchen, and boiler are close to each other. However, it’s important that hot water is not used by two people at the same time, meaning that combi boilers are best for houses with just 1 bathroom and kitchen. A combi boiler should be fitted into one of those rooms so that it is in close proximity to hot water taps. Otherwise, if the boiler is located far, then it would take a long time for the hot water to reach the tap.

For a larger house, with 2 or more bathrooms, and more than 3 residents, a system boiler would be the best option as it will be efficient, and the temperature will stay stable. It is also possible to use a circulation pump, which is essential for bigger installations. Thanks to extra circulation circuits, hot water will stay in the system where the temperature will be maintained, meaning that the water will not cool down and will be available as soon as you turn the tap on.

You will be advised by expert from Romford Emergency Plumber in choosing the boiler.

How to avoid clogging the drain

A clogged sink (in the kitchen or bathroom), shower, bath, or even a toilet in Romford can be really frustrating and can happen to all of us. To prevent such problems, you should regularly perform a few simple steps that will save you many problems and expenses as you will not have to call a plumber.

In the kitchen, do not pour oil into drains as it accumulates in pipes from the inside and significantly reduces the diameter of the discharge pipe, which can sometimes cause an entire blockage. Do not throw food scraps down the sink, such as potatoes, rice, sauces etc. You can insert a protecting net in the kitchen sink which will stop many undesirable items falling into the drain and blocking it.

In the shower tray, bath, and sink, it is worth regularly, at least once a week, cleaning the siphon and getting rid of any hair, you should also make sure that items such as ear/cosmetic buds, hair clips, toothpaste lids, and etc do not fall in. Furthermore, avoid flushing things like tissues, paper towel, tampons, sanitary towels, and etc in the toilet.

Once a week, preferably before going to sleep, use a chemical drain pipe flusher – for example, pellets or gels; e.g. caustic soda. By following these steps your drain pipes will always work without any problems and you will not need to call an emergency plumber in Romford.

Always keep chemicals out of the reach of children and animals because they are very dangerous. Avoid inhaling the fumes. Before using chemicals please refer to the manufacturer’s instructions on the leaflet.

How to Choose a Plumber

During the renovation or repair of central heating, hot and cold water, or gas in Romford, we always come across the dilemma of what plumber to get to do the job. In many cases, when we undertake such work we are also likely to renovate the kitchen or the bathroom. Therefore, it is worth remembering that many plumbers are not limited to individual orders. If you choose a true professional, you will not have to worry about the work being done poorly.

Choosing the right plumber in Romford is thus not easy, you have to make sure that they have a gas licence and are registered with Gas Safe. A large number of companies operate in the current market, meaning that finding the right plumber in Romford doesn’t have to be difficult. Virtually, every person is able to undertake such work, you just simply have to show a bit of caution and a sensible approach. Thanks to this, you can avoid problems and quickly repair any leaking pipes or a broken boiler/central heating.

Speaking of plumbing companies in Romford, it’s impossible not to mention the so-called emergency plumbers. They are an excellent way of quickly resolving any accident or expanding your installation. Such companies are usually open 24/7, 365 days a year which ensures a very fast access to the client at any time of the day or night, addressing any kind of emergency that can take place in your house.

How to drain the heating system

When it is necessary to update your existing heating system in order to e.g. change the location of the radiator, an emergency leak, or paint the wall behind the radiator, and etc, we can drain the water from the central heating system. For this we need to stock up on drain hose and locate a valve to drain the water from the central heating. It can usually be found near the radiator or boiler at the lowest level of your house or flat. Place the hose on the tip of the outlet valve and then place the other end out in the garden or in the drain so that it is not higher than the drain valve from the central heating. Turn off the boiler’s power, in case you have an open heating system, shut off the water to the tank which is usually located in the loft of your house. Then, gently unscrew the valve using an adjustable wrench, if the valve is old and does not unscrew then you have to call in a plumber (Emergency Plumber Romford can do this for you). After that, unscrew the radiator bleeding valve at the highest level of your house. This should be done on a cold radiator as a warm one can burn you. After draining the water and performing the planned work, you have to refill water the heating system and inhibitor to the appropriate pressure, check for leaks, bleed central heating system and switch on the boiler. This can be dangerous if done by an unskilled plumber as it can result in flooding of the house and damaging the body of the central heating system. Therefore, the work must be performed by a qualified plumber. Romford Emergency Plumber will do this work for you, quickly and safely.

Watch out for Legionella bacteria!

Legionella bacteria can cause many diseases, some more serious than the others, they include Legionnaires’ disease which is a serious disease, the less serious are Pontiac fever and lochgoilhead fever, the term used to describe those diseases is Legionellosis. Everyone could be infected by Legionnaires’ disease which is a fatal form of pneumonia, however the most venerable people to the infection are those of age +45, heavy smokers and drinkers, those that suffer from diabetes, lung and heart diseases, chronic respiratory or kidney disease or anyone with impaired immune system. If you’re one of them then you should really watch out for any type of Legionellosis.

Natural water sources such as rivers, lakes and reservoirs are common sources of the bacterium Legionella pneumophila however, they are in small numbers. They also inhabit artificial water systems such as cooling towers, hot and cold water systems, evaporative condensers and spa pools.

This bacterium could potentially grow and greatly increase the risks of Legionnaires’ disease, if the conditions are right. Otherwise it will remain in small numbers if the appropriate measures are taken to control it.

Legionella bacteria is natural in natural water systems such as lakes and rivers however, the conditions it is at are not favourable and therefore the risks of people getting it from those sources are rare. On the other hand, in artificial water systems, where the temperature is high enough to encourage the growth of the bacteria, outbreaks of the illness could occur. Those water systems include cooling towers, spa pools, hot and cold water systems, evaporative condensers, etc.

 People get infected by legionnaires’ disease by inhaling water vapour that contains the bacteria. The conditions favourable by the bacteria and that will increase the risks of getting Legionellosis include the water system has temperatures between 20-45 °C which encourages the growth, when water vapour or small droplets of water are created by cooling towers or water outlets, the water is being stored and/or re-circulated and lastly, the deposits of nutrients for the growth of the bacteria into the system, such as rust, sludge, scale, organic matter and biofilms. Most of the Legionnaires’ diseases are caused by infections within UK however, some of them could also occur abroad.

The symptoms of Legionnaires’ disease include high temperatures, feverishness chills, cough, muscle pains, diarrhoea, headache occasionally leading to pneumonia, and lastly signs of mental confusion, those symptoms are very similar to flu. Legionnaires’ disease is not known to spread between people. You can treat this illness by using antibiotics called erythromycin or a similar antibiotic.

If you have some of those symptoms and you worry that you could have got Legionnaires’ disease then you should go and see your general practitioner. As this disease is extremely similar to flu, it is hard to diagnose, and so blood or urine tests could be really helpful in diagnosing it, on top of that if the community is known to have this disease by the doctor then it will be easier for them to diagnose it and treat it early. If you believe that you caught this disease at work then it is a legal requirement that you notify and report this to your manager as well as to your health and safety representative and the health department is you have one. It is a legal requirement that you report the cases of Legionnaires’ disease that could be caught at their work place, you should report this to the Health and Safety Executive. Also as a landlord, you must ensure that your property is safe for your tenants so you must make sure that the water systems within your property do not contain the conditions for the development of Legionella bacteria.

Romford Emergency Plumber does disinfection of water systems and dose have a qualified personel to carry out those services. Call us now and don’ fall a victim to Legionella.

Before You Call a Gas Engineer – Advice

Not every problem with the boiler requires a call for a gas engineer who will charge you for doing something that you can do yourself.

In case of problems with the boiler, before you decide to call for a gas engineer, it’s worth following the instructions below. They can help you to fix a problem in the operation of the device without the need for a gas engineer’s visit, and in case a visit is necessary, it will allow the engineer to operate more efficiently. These are activities that are within the scope of service, which according to the of manufacturers book , can be performed by each user:
Check the boiler’s water pressure on the pressure gauge to ensure that it is within the range recommended by the manufacturer, this is given in the manual instructions. If it is too low (below 0.8), fill the water pressure to the recommended level (1.5 – 1.8 bar).
Check the connection to electricity.
Try turning the power switch off and on again. If the lockout information is displayed (red lamp, crossed-out flame, etc.), press the reset button. If the boiler starts to work after this, it should be observed for any signs of abnormal behaviour – e.g. water leaks, unusual noises, etc. If anything arouses your suspicion, for your safety it is best to switch off the boiler immediately – disconnect it from the electricity supply and shut off the gas supply. If there’s a water leak, close the shut-off valves and call for an engineer.
If a room stat (thermostat) is connected to the device, check that it is connected correctly. If it is battery-powered, check whether the battery needs changing.
If the above steps did not help solve the problem, or if the boiler is working in a faulty way (e.g. not heating properly, lockout, leaking, making excessive noise, etc.), please consult a gas engineer. It is also worth giving a call to a gas engineer if the appliance has not been serviced for a long time (over a year).

Before talking with a heating engineer, it is best, if possible, to prepare the following information:
First of all – boiler brand and model. This information can be found in the manufacture instruction or on the dataplate if it is visible from the outside. If the name of the model is not known, it will also help to provide, even roughly, the year installation and type (e.g. floorstanding or hanging boiler, system or a combination, etc.)
A detailed description of the fault: how it manifests itself, in what circumstances it occurs – e.g. in an accidental way, sometimes, and maybe always under certain circumstances, e.g. it does not heat up the water. If the fault consists of a small water leakage, it is worth noting which side of the housing we see the leak at. If the fault manifests itself as an occasional lockout – pay attention to how often this happens, maybe at certain specific moments.
Preparation of the above information will significantly improve the conversation and enable more precise determination of the scope and cost.

We recommend caution when working with gas appliance.

If anything arouses your suspicion, it is best to switch off the boiler immediately and call a gas engineer or a service technician.

We do not advise independent repairs of gas appliances.

The heating appliance is: gas, electricity, hot water, steam, toxic fumes.

Only professional and regular service ensures safety for you and your family.
