Learning a trade

A recent study by education charity Edge and the City & Guilds Group found that parents think plumbing apprenticeships make young people more employable than their peers who studied at university, however most of them said that they still wanted their children to get a degree. At the end of the day, what you study is your choice, so it’s pretty important to seek out other routes into employment, and apprenticeships is a pretty good one.

Apprecticeship2

So why not do both? Many companies are now fully aware of the benefits of having graduate engineers who have learnt a “trade”, they understand the business from the ground up and have spent time with semi skilled tradespeople in the shop floor where they will have developed a healthy respect for the value they add to the process. PwC’s retention rate for apprentices is 85.8%, compared with 67.7% for graduates, after qualifying. There is the opportunity for everyone who completes an apprenticeship to remain with PwC and to take advantage of ample career support and job opportunities.

New boiler in a handy place

We have serviced this customer’s boiler for a number of years but as it became less reliable it also be came much less accessible to fix. The boiler had originally been located in the utility room but it’s flue was deemed to be too close to an opening window and so was moved up to the loft. Unfortunately the clients are elderly and disabled and so having the boiler in the loft was clearly impractical.

Moving the boiler back to the ground floor was always going to present a challenge with the flue as the only really suitable place was the original location. FlueAfter some research it was found that Worcester Bosch had developed a horizontal flue which can be used on a pitched roof. Other manufacturers weren’t able to offer the same setup because the paint used on the flue wasn’t UV resistant! The Technical Bulletin (0042) describes how the flue can be fitted to the roof and all of the dimensions that need satisfying.

A Greenstar Worcester Bosch  boiler was selected for its superior reliability and work commenced in uncovering the old pipework located in a tight space behind the kitchen cabinets.2018-05-17 15.21.54

As with all boilers we fit a magnetic filter was supplied and fitted to the system to qualify for an additional 1 years additional warranty.

As the boiler was in the utility room it was obvious to us that the above bench pipework needed to be as neat as possible. Making this neat and symmetrical was slightly complicated by a fused spur from the previous boiler being locate in the path of the gas pipe. The gas pipe was moved to the left and the remaining pipes kept close to it so that a clear space could be left for the electrical outlet.Mayes pipes The trickiest part of the job was to make sure the flue was located in the correct position to allow it to comply with the Technical Bulletin’s specification.

The main requirement was that the end of the flue had to be 300mm vertically above the surface beneath it to prevent snow from blocking the flue in another, “Beast from the East”, occurrence . This was going to be difficult on a roof with a pitch of about 30 degrees as the telescopic extension was only about 350mm long. A bit of quick school trigonometry.

New Picture (68)

2018-05-16 10.45.01Clearly for a 30 degree roof the 220mm elevation is not enough and so the flue was extended to hang over the end of the roof meaning the vertical drop was down onto the guttering below. The flue was secured with proprietary hangers and the roof rebuilt and pointed in to reduce draughts.2018-05-17 16.10.57

Finally a hatch was cut into the ceiling to allow for future inspections of the flue joints and the boiler in the loft was stripped out and taken away with all of the pipework disconnected and cut back to ensure it’s fully out of action.

Bosch Easy Control–New system

UnventedWe are delighted to have installed the new Worcester Bosch Easy Control internet based heating control centre. We were asked to fit a new boiler in place of an old and unreliable Baxi 130HE combi. The customer opted for a new Worcester Bosch 30i system boiler and 300L unvented cylinder.

The unvented cylinder has transformed hot water supply in the house from having one shower able to perform reasonably at 15 litres per minute, the customers now have a bath capable of delivering 20 litres per minute as well as two showers delivering 15 litres per minute. With 300 litres of hot water at 65oC and the 30KW boiler refilling the cylinder every 28 minutes, its almost impossible to run out of water.

The Bosch Easy Control takes care of the control of the heating and hot water. From the customer’sEasy control iPhone a schedule can be set up to automatically start and stop the boiler when heat in needed. The controller takes account of the outdoor weather temperature and alters the output of the boiler to compensate for additional loss of heat through the building fabric as the external temperature drops at night.

Call from the East

I awoke yesterday morning to shanghaifind an email from a new customer asking if I would give him a second opinion on a gas boiler he had at his rented house in Newcastle. I didn’t realise at the time but the 6am email had come from Shanghai, China, the customer was an English teacher in the Far East!

 Making arrangements

I responded to the email, arranged a visit with the local letting agents and inspected the boiler. The tenant had reported that the boiler was switching on and off every five minutes and on inspection I could see why.

Potterton Prima 30F – combustion safety device

flame liftLooking through the spy glass at the flame picture I could see the flame lifting off the burners. These boiler are fitted with an oxy-pilot“oxy pilot” pilot light which is designed to shut down the boiler if there is a lack of oxygen in the combustion process – this is what was happening.

The next step was to determine why there was a lack of oxygen and why the pilot light was lifting off the burner causing the thermocouple to cool down and switch off.

Flue problems

2018-04-12 10.24.20In most cases the lack of oxygen is due to flue problems. If a flue is blocked then less air is able to get into the boiler causing combustion problems, but also if the flue is damaged or corroded then exhaust gases can get into the intake of the boiler and as these are primarily CO2, they starve the boiler of oxygen. Taking a look outside at the flue it could be seen that the terminal had been poorly pointed in but this was a historic fault and the current problem had just arisen so there was more to it that that poor pointing.

Corrosion of the flue

2018-04-13 08.50.46On closer inspection of the flue it was obvious to see the inner exhaust pipe had completely corroded to the point that there was a large airway between the exhaust pipe and the air intake resulting in the boiler breathing in its own exhaust gas. This is likely to cause high levels of CO as the combustion process is compromised by the lack of oxygen and produces CO rather than CO2.

2018-04-12 12.45.52The boiler was restarted and the CO levels measured to see just how bad the combustion process has become, as you can see the level is very high, 1600 ppm (parts per million) a level that will cause death in 2 hours if the gases were able to get into the house.

 

2018-04-12 11.17.42I classified the boiler as “At Risk” and disconnected it from the gas supply and issued a warning notice until I was given to go ahead to repair it.

2018-04-12 11.17.50

Simple fix

2018-04-12 13.10.51Baxi are aware of this problem and make a simple rectification part (5106693) which neatly fits over the distressed flue pipe. This was purchased, fitted and the CO levels remeasured at 42 parts per million, a much safer level.

The work was completed and the photos sent to Shanghai for approval by the customer who was happy with the work and left a very kind review on Checkatrade – IMG_2865“I can’t thank Richard enough, he’s quite literally a lifesaver, picking up on serious issues missed by a shoddy craftsman obtained by my property manager as I work abroad and rent out my home in Newcastle. He also saved me having to replace the boiler entirely. Thank you, Richard, for your prompt and excellent work as well as the communication, information provided, upfront pricing and photos. It’d be my pleasure to recommend Richard here and I’m definitely keeping his number for any future work as well as sharing it with my family and friends in Newcastle as often as I can.”

SNOW! better time to check your heating system

2018-02-28 07.38.30Thankfully the snow has gone for the moment. It was a very busy time for us with calls every hour asking for help. We were able to answer many of them and were happy to give people advice on how to get their boilers working again. One local customer even left us a kind review on Checkatrade for helping him out. http://bit.ly/BEEREVIEWS

“Very kindly offered advice which overcame boiler failure meaning a visit was not necessary, without charge.”

New Picture (50)

Now that temperatures are above freezing its an ideal time to review your systems and plan in a little bit of preventative maintenance to save the discomfort and worry next time the Beast comes from the East. 

Having a heating system that doesn’t effectively heat your house is worse than useless!

New Picture (51)We can review your heating system and make improvements such as refiting or rerouting your condensate pipework so that it doesn’t freeze, we can review your radiator outputs and look at the amount of sludge there is in your system to give your boiler a fighting chance of circulating some real heat on colder days; and we can install Smart Controls that learn when you want your heating on and take account of the external weather conditions.

Correct cleaning of your system

Many people will be getting new boilers at this time of year because this is when they are most likely to fail and with the pressure and stress of the cold weather its sometimes best to opt for a new boiler. I many cases the replacement is due to the old system being tired and exhausted and clogged up with years of dirty water in the system.

When a new boiler is fitted it is part of the Building Regulations that the system is flushed out in accordance with BS7593. This means flushing the system with either a fresh water approach or a power flush approach, details of each can be found at the Domestic Water Treatment Association’s code of practice – http://bit.ly/BEEWATER

We normally opt for the fresh water approach as we feel it places the system under less stress and with many manufacturers they provide an installation jig for easy flushing, pictured below you can see how the filling loop is used to introduce fresh water into the system and a exit pipe is attached to the flow connection thus allowing water to be introduced and flow round the whole system with out going through the boiler – which isn’t fitted at this stage.

The process is further refined by then shutting of all but one of the radiators so that it can be heard that the flushing water is running through that radiator, this is continued for all the radiators in the system. The exiting water usually turns a darker colour as each new radiator is opened up.

If you are having a new boiler fitted and the fitters are suggesting that they don’t need to flush the system as the magnetic filter will remove all of the dirty walk away!! This is not correct, don’t let them pull the wool and contaminate your new boiler with years of old sludge.

Derek’s Diary – “House Warmer” not that warm!!

Derek’s been out and about buzzing around looking to help folks in this cold weather. We were contacted by one young man who had just moved into a new house with a young family, in Tyneside, but had no heating or hot water. It turned out that the “Thorn-Myson House Warmer 30/45” wasn’t doing its job and so we set about fixing it.

This is a dear old lady who ceased production in 1988 so we are looking at a 30 year old boiler.

The first problem as a blown capacitor in the wiring centre, this was easily replaced. 2017-12-13 22.01.50The picture opposite shows the capacitor exploding as voltage is sent across it.

Then the pilot light didn’t work so this was also replaced. Finally it began to work but the circulation pump had sheared off, so that had to be replaced. The pump hadn’t been supported very well so we added some supports and new valves and now it works perfectly! It just goes to show that with a little TLC you can bring an old dear back to life.

2017-12-09 09.04.31Our client, Paul, commented – An excellent job on an old, dated boiler and heating system which had not been maintained prior to me purchasing the property and had several issues. Richard was open and clear with expectations of potential issues and cost and endeavoured to sort it as quickly as possible, including coming out at weekends and evenings. I cannot fault the service provided at all.

We were delighted to has been able to assist Smile

Derek’s diary – Boilers and Gas Cookers

We don’t just fix boilers, but you probably know that!

Bee3 cleanerThis week Derek has been busy fixing a lot of boilers, replacing pumps, finding leaks and getting gas ovens to work.

2017-11-23 12.44.24In one job the gas oven’s automatic sparker would start all by itself and just keep sparking, this was driving the customer mad!!

We found out that the flame was lifting off the burner because the burner was dirty and so we sent Derek into the hot oven to give it a good clean; after that it worked great.

2017-11-23 12.49.00

Bee3 cleanerIt just goes to show that cleaning your oven is important and can say you the cost of calling out a gas engineer to clean it for you.

On another day Derek found himself in a loft with a few wasps and the odd bat! While he was up the, at the property in North Shields, he replaced the gravity feed central heating pump on an old Apollo boiler which was installed about 30 years ago.

2017-11-21 10.33.17Unfortunately just as we replaced the main pump the thermocouple went as well so we replaced that too.
