No more gas boilers? You must be joking!

The media seems to be awash today with the announcement that the government HOPE to have no more new gas boilers sold after 2035. The devil of course is in the details….

At the moment I am working on a project at the HQ of a local parts supplier to do away with the existing (quite new) gas boilers and convert the place to VRV AC system. The existing gas loading is about 900kW so if I stick in a VRV system drawing about 300kW that should do. This would add about 400A per phase. Assume every other office block on the estate decides to ‘go green’ and do the same and straight away you are looking at some serious deficiencies in the local power infrastructure. Add in charging electric cars (we already have issues trying to charge 7 electric cars at 4 charge points in this office) and the potential for thousands of homes to all be heated by electric and I foresee a looming catastrophe.

Of course, the obvious solution is to upgrade the local and national grids to futureproof them and bring online more generating capacity but do you see any new power stations being built (apart from Hinkley)? Any new power lines/substations appearing? Or are we going to swap gas heating for electric heating run from gas generation? And what about the existing nuclear stations reaching the end of their lives? Discuss….

  • In the short term, we could add a little hydrogen to the natural gas.  Like our petrol is now 10% bio-ethanol.

    But 100% H2 would require new boilers, or at least the old ones adapting.  We managed that when we went from town gas to natural gas.

    But if the H2 is going to be green and affordable, it needs to be generated from spare electricity.  That means over-building wind and solar, then on windy or sunny days, generate H2 and store it somewhere.  If only we hadn't removed all our gas storage in the UK.
