Hi All,
I would appreciate your thoughts, comments and advice on the below situation.
I moved into a new house a year ago. The house has a few gas appliances:
As a new owner for the house, this year I got a local Gas Safe registered company to conduct the service, and during the service the engineer noted a few things:
So to rule out supply issues, Transco were called. Transco arrived within two hours and agreed to replace the regulator on the gas meter to rule it out as the problem. The regulator was replaced, and the pressure at the meter was now 21/22mbar. Transco also looked into their records and stated that the regulator was previously replaced in April 2013 when the supply was increased to 32mm, as a result of a previous “low pressure” callout. With the new regulator in place, the pressure at the boiler was now measured at 18mbar. So still a 3 to 4mbar drop!
So what does my system look like?
Well the gas meter is at the back of the house and is feed by a 32mm supply. This supply splits in to:
The Service Engineer checked the pipework and filter for obvious issues and suggested that British Gas who installed the system were unlikely to have tested the pressure at the boiler when it was installed and Transco confirmed that British Gas do not tend to do this. So the advice was to go back to British Gas and complain. However given the amount of time that has elapsed this does not look likely to succeed. The Service Engineer also seemed a bit surprised by the pressure loss, given that the pipework between the Gas meter and the boiler was mostly 28mm!
So what are your thoughts? And what would you do?
Is this an issue that I can live with or is it something that can be dangerous? I appreciate that when demand exceeds supply that sometimes appliances can flame out! But in reality my usage is boiler versus cooker. Not boiler, versus cooker, on-demand hot water & the gas fire).
Any advice is gratefully received!
Thanks
I would appreciate your thoughts, comments and advice on the below situation.
I moved into a new house a year ago. The house has a few gas appliances:
- A Worcester Greenstar Conventional 40CDI boiler that supplies 11 to 15 radiators, and hot water. Although hot water is to a cylinder (not on demand) as the water is also topped up with solar heating.
- A gas fire (not used).
- Five gas hobs on the cooker (the oven itself is electric).
As a new owner for the house, this year I got a local Gas Safe registered company to conduct the service, and during the service the engineer noted a few things:
- The boiler had previously had a fire at some point in time (which had been fixed). This was evidenced by discolouration inside the casing. These issues are apparently not too uncommon with the Worcester.
- The boiler needs new electrodes (the current ones have some splits in them) – to be done.
- The boiler needs a new automatic event (the current on is on its way out, as evidence by it emitting scale) – to be done.
So to rule out supply issues, Transco were called. Transco arrived within two hours and agreed to replace the regulator on the gas meter to rule it out as the problem. The regulator was replaced, and the pressure at the meter was now 21/22mbar.

So what does my system look like?
Well the gas meter is at the back of the house and is feed by a 32mm supply. This supply splits in to:
- a small bore pipe (15mm??) than runs for about 1.5m into the back of the Gas Fire.
- a 28mm pipe that runs up away from the meter and passes through the house (at ceiling level, not underfloor) to the boiler at the front of the house. The pipe work between the meter and the boiler is around 6 to 7m in length and appears to be 28mm until the last say 50cm before the boiler, where to drops down to 22mm to enter the boiler. Between the gas meter and the boiler there are maybe 2 x 90 degree bends in the pipe.
- At the boiler there is another split in the pipe, with a 22mm pipe running along the from the of house to re-enter the house at the kitchen to feed to cooker. This pipe is around 5m long and has a few bends in it.
The Service Engineer checked the pipework and filter for obvious issues and suggested that British Gas who installed the system were unlikely to have tested the pressure at the boiler when it was installed and Transco confirmed that British Gas do not tend to do this.
