Switching to zero carbon heating for our homes is a very hot topic at the moment, and it seems that it’s in the news constantly.  The UN’s COP 26 summit is nearly underway and the focus is very much on sustainable, zero carbon energy.

There has been a lot of speculation about the future of gas boilers, with some propaganda directing home owners to change their gas boilers by 2025.  We want to make the point that YOU DON’T HAVE TO CHANGE YOUR GAS BOILER BY 2025!  It’s not a requisite of the Government, nor are you going to be fined or sent to prison!

Anyone who is unaware of the urgency of the world to get to grips with climate change must be both nocturnal and have been in hibernation for the last decade, so it comes as no surprise that all technology companies are focusing on reducing their carbon output.  But there is some misinformation out there, so we wanted to put out in our blog the correct information about gas boilers in the years ahead.

Gas boilers, although the most common type of heating in our homes, are not carbon efficient.  The carbon they create has a detrimental effect on the planet, because of the fossil fuel they burn.   Considering that the majority of homes are heated by gas (about 80%), it’s obvious that by switching to a zero carbon heating system, we could, collectively, as a nation, wipe out around 20% of our total carbon emissions.

So, with that at the forefront of the Governments Green Policy, technology companies have been researching alternative systems, including hydrogen boilers and heat pumps to help the nation when it comes to switching to zero carbon heating systems.

The year of 2025 that’s being banded about is the date that the Government will ban the installation of gas boilers in new build homes.  About 160,000 new homes are built every year, so this is the start of the Government’s plan to reduce the UK’s carbon emissions to zero.

So switching to zero carbon heating in your home by a certain date is not true.  There is no Government deadline as of yet, but most experts are of the opinion that there may well be by 2028-2030.  The truth is that the industry couldn’t cope with production capacity anyway, if we were all to change our boilers tomorrow!

However, the Government is keen to wipe out carbon emitting heating systems in line with their policy ambitions for 2050 and that’s why they’re encouraging us now to change our boilers over with incentives to do so.

Technology surrounding switching to zero carbon heating falls into 3 categories:

  1.  Insulating our homes more efficiently In a Government report, it is estimated that 25 million homes do not meet the required standard of insulation.    The rate at which we are insulating our homes has fallen dramatically since 2012 and the Government is keen to increase this.  Why?  Because the amount of energy used to heat un-insulated homes is huge and therefore a massive contributor to carbon emission.
  2. Air and Ground Source heat pumps – these pumps pull in ambient  heat from either the air or the ground and pass it through a comprressor which heats it further.  It’s then passed around your heating system without the need for fossil fuel
  3. Hydrogen boilers – the gas that hydrogen boilers produce is manufactured from water, which is doesn’t produce carbon emission.  If the electricity it uses comes from a renewable source, then heating your home this way will give it a zero carbon footprint.

We hope that this information has laid bare some of the nonsense that’s surrounding this hot topic.  It’s true that we’re heading for big changes in the way we heat our homes, but there is no deadline to change your boiler.  When the time comes to change it, due to it being faulty or old, it may well be that gas and electric boilers will no longer be manufactured, but more energy efficient alternatives will be the norm.

But at the time of writing this blog, there is no deadline for home owners to change their boilers.  The onus is on the construction industry by 2025.
