NewsThis Valentine’s Day we want to let you in on a dirty little secret…
It’s true, size does matter, especially when it comes to getting you hot this February.
In this blog we’ll be exploring new size regulations for boiler gas pipes, and telling you how if the job needs it, our engineers can lay some pipe, no problem at all.
The sensory rush of hot water dancing down the back of your neck, soothing steam matching the temperature of your skin, the cool sting of the shower glass on the palms of your hands…
Not quite the same if you both have chattering teeth and the water is half frozen.
You may need a thicker pipe to finish the job.
A gas pipe or ‘boiler gas pipe’ is a branch line from the mains building line or ‘gas supply pipe’.
Boiler gas pipes split off from this mains connection and run to the gas powered appliances around the home, i.e. a boiler.
Gas pipes deliver gas from the meter to be used as fuel by the boiler to generate central heating and domestic hot water.
Boiler gas pipes are commonly constructed from copper or alternatively some types of pipework can be constructed of steel, brass or aluminium.
Gas pipes can vary in size (inc. 15, 22, 28 or 35mm) often depending on the distance between the gas meter and the boiler, the boiler’s brand/model and the size of the boiler.
Older properties have usually been fitted with 15mm diameter pipes, newer combis may be more compact but require a larger deposit of gas in a less amount of time than most traditional boilers.
Combis have a more substantial gas demand due to their instantaneous hot water delivery as opposed to cylinder storage. This hot and fast delivery means a combi is suited to being filled by thicker pipes, to supply as much gas as possible.
System or regular boilers heat water in a slower process involving a hot water cylinder, not needing high volumes of gas in as short a space of time as a combi, meaning often 15mm can be sufficient.
For a combi to be operating as optimally as it should, providing you with central heating and hot running water, Gas Safe states its pipes should be no smaller than 22mm.
If the pressure is too much for the pipe it could burst or leak, leading to more serious plus potentially dangerous problems.
Let’s face it, bigger pipes can heat up your bedroom and make those shared showers truly tingle on February the 14th.
Changing or upgrading any gas pipes on your boiler should be left to the experts, all of our engineers here at iHeat are Gas Safe registered and pack the tools to finish the job.
During a boiler installation or conversion, If the run (length of fitted gas pipe) that needs replacing is a standard length, our engineers will replace any 15mm pipe with new rock hard, rigid 22mm piping, and at no extra cost!
(In some cases if the pressure is fine with lower sized piping there is no need to change from a manufacturer warranty side of things, but Gas Safe may still advise an upgrade.)
Our fixed quote prices are exactly that, even if your piping needs upgrading on the day, we charge no extra for our brand new boiler costs.
