Roof structural support

Along with the underfloor heating, we have been calling on our construction skills to fit a series of steel supports for the new green oak trusses that are due next week.

The next stage of the work is to remove the existing roof structure and fit the new oak trusses which we will be bringing in with a crane.

Above is an example of how the trusses will look.

Part 2 – concrete sub floor

With the stone sub base in place and nicely compacted down we are now ready to start the prep for the concrete. With it being such a big area (11m x 5m) we have split it into two bit size chunks and shuttered these areas so these can be poured first. The concrete is due for delivery on Monday.

Small is beautiful

IMG_3683Derek’s been a busy bee this morning. Luckily he’s small and can get into tight spaces so it was no trouble for him to bend some copper pipe and fit it under a boiler to supply a new garden tap.

There really is not limit to Derek.s abilities or the type of work he will do. Lots of people need a garden tap and Derek was happy to oblige.

If you need an outside taps for these hot summer days to fill the paddling pool for the kids or just to water the garden (unless there’s a hose pipe ban) call Derek and he’ll gladly fit one for you.

A tale of two flues

Bee3 cleaner2018-06-19 17.20.18Derek’s been a busy bee this week looking at flues. At one property, when we went into the loft to inspect the flue, we noticed that the flue hadn’t been screwed together properly and that there wasn’t enough brackets on the flue pipe to hold it in position. The picture on the left shows another section of the same flue which has been fitted correctly. Note the brackets AND screws holding the parts together.

The problems is not that its dangerous NOW, but we have to consider what might happen in the future. If something or someone was to inadvertently interfere with it, the parts could become dislodged and this would allow products of combustion into the house, this in turn may get into the boiler causing it produce carbon monoxide, which of course is deadly. Derek and I determined this to be “At Risk”* and with the owners consent disconnected the gas supply so that it simply couldn’t be used. Documents were completed and issued to the home owner.

By chance, the next day, Derek and I had another call from another customer who had, this time, had his boiler condemned by another Gas Safe engineer and wanted a second opinion as he was facing a bill of several thousands of pounds for a new boiler.

2018-06-20 14.40.35 (2)In this case the engineer had determined that the boiler had failed the “spillage test” and the “smoke pellet flue flow test” and had determined that it was “At Risk” and as such issued a Warning Notice and labelled the boiler as “WARNING – DO NOT USE”.

 

2018-06-20 13.37.19I carried out some tests myself and found them all to be OK, so I rang the gas fitter and asked him what he had found. He said that the CO2% was too low and that I should know that and that is why it’s unsafe. Therefore I rang Baxi to check the figures and was told that there is no published value for the CO2% and so the figure I had found of 6% was fine, not dangerous. I removed the Do Not Use notice and reissued the Home Owner Gas Safety Certificate. 

The clients were delighted that they haven’t had to fork out over £2000 for a new boiler and are now confident that their gas appliances are safe.

* At Risk (AR) means – An “At Risk” installation is where one or more recognised faults are present which could constitute a danger to life or property without further faults developing – further reading available at :- http://bit.ly/beeARAR

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.

Commercial Gas Engineer

I am delighted to have passed my commercial gas engineer qualifications.This means I can now work on industrial gas equipment such as boilers, air warmers and pipe work, allowing me to service and repair appliances as well as make alterations, purge, test and commission pipelines.

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.
