All Gas Boilers banned from 2025 www.bbc.co.uk/news/science-environment-57149059" Models designed so they could switch to burn hydrogen could be an option - and will probably be around £100 more than the £2,000 standard gas boiler.
This will help the climate because hydrogen from renewables burns with no emissions.
But climate advisors say it will probably only heat around 11% of homes, because hydrogen supply will be limited." |

No because they all still need servicing & fixing
It’s for new installs
A bit like electric cars

Hydrogen is made from gas so we are going backwards, Once we went from coal gas to natural gas because it was cleaner than coal gas which was made from coal, now you are going from natural gas to hydrogen which is a gas made from fossil fuels including natual gas,  |

Could it separate the course cowboys who can install nothing but 3 models of boiler from the more experienced gas engineer who is capable of stripping any boiler down and locating the faulty part? |

It’s irrelevant to the skilled Heating Engineers.
Switching between fuels has always been required.
As for New Builds for example; Air Source Heat Pumps have been installed in many for some time. Then there’s the SAP ratings.
Personally, I’ve worked on around 8 sites with ASHPs over the last 8 years.

ASHP's have come on leaps and bounds in recent years, My eldest who lives in Canada had it installed last Autumn ( fall as they say ) and what a difference it has made, It can be -20 outside but 20C inside, Its the best thing they ever did and, the electric bill is buttons, Its saved them a fortune in Wood and electric, So in celebration, his wife bought a hottub and put it in the garden, so now in Winter they bathe in a hot tub when its minus brass monkeys in the garden, then jump out and run into a house thats 20C to warm up, the ASHP uses next to nothing in electic but, the hottub casts a arm and a leg, you could't make it up, out of one hand and in with the other,  |

I find this happens sometimes with energy saving devices. For example, LED lighting. Now that they're cheaper to run, people have lots more lights which defeats the object. Some houses around here are lit up all night like Blackpool illuminations. Not just inside, but gardens too - even when there's no fooker in them, summer, winter - whenever.
My brother's lounge had two spotlight fittings with 3 halogen GU10s in each fitting. When he renovated his lounge he removed old fittings and put in 18 LED downlights. But because they're not dimmable, they far too bright for relaxing even though they're the lowest output bulbs. Mostly he has a single table lamp on in the evening. Also, if one of the new LED downlights blows, there's no bulb to replace. The whole fitting has to be removed and binned. Madness!

Bloody hell! Makes me feel better about putting only 6 spots in the kitchen - I was a bit worried at the time if it was enough. On highest power led bulbs its very bright but not blinding. I opted to fit the the downlights with replaceable bulbs. |

Good move fitting replaceable bulbs. LED downlights are ok in a kitchen or bathroom, but unless they're dimmable they're overkill for lounge or bedroom. Not even sure if you can get dimmable LEDs.

when you get to my age, there's no such thing as overkill on illumination, The brighter the better, my last eye test revealed early onset of cataracts, sooner or later i'm gonna need eye surgery and jam jar bottom glasses,  |

One of the first things I do when entering a dark property is switch on the light, so I could be going the same way as tom without even realising it!
ASHPs and I can't make my mind up about them (Some people say there the best thing ever whilst others are completely the other way on them).
Our local council installed GSHPs in a row of OAPs bungalows some twenty years ago mainly replacing solid fuel systems and the OAPs hated them so much that they got a petition up to have them all removed after only about 10 years of use.
NB. Fitting a time clock on the above was a big mistake by the council because the old un's would set it to come for just 2hrs a day (which is no good at all for this system) but you could never get through to them on this topic!
My current thinking on them is "if you are affluent enough to be able to heat your rooms to the governments recommended temperatures with your current form of heating then you should be able to save a bob or two by installing a ASHP/GSHP".
Saving the planet by going green and fitting a heat pump is a different issue because it all depends on how that electricity running the heat pump is produced in the first place!

I have no practical experience of them at all, I'm just polly parroting what my son tells me, He paid just $8000 CDS which is about £6.000, for that he got 2 units installed in 1/2 a day and it changed his life, he also told me that a mate of his got the same installers to his house but, got a cheaper system that cost them $5000, they were disappointed in their system, That rings true to me and reminds me of an old saying, only a very rich person can afford cheap carpets,  |

Noise is a big problem with ASHPs, especially in winter when we get the beast from the east - then the units need to be on 24/7 to keep pace.
Maybe we also need a back up form of support heating here in the UK?
Early days yet though for these units.
Seems to back up what I come across tom, two different people with very different opinions on heat pumps.

he was instucked to run it 24/7 using the low setting and use the stats to control it, Keep all the internal doors open and it works great, After a couple of days, the whole house was in the 20's just using those instuctions, Women being what they are turned it up, a couple of days later the house was a sauna and no one could sleep even though the outside was -20 C
And yeah, it got noisey,
So its best used 24/7 on low and in his case it works very well and economical and the bonus is, Its an air conditioner too so, in Summer where they can get temps of 35 degree's C, it will keep the house cool,

About 14 years ago I stayed in a cottage in Devon that had ground source heating. It was winter, but reasonably mild - certainly above freezing. What struck me was the noise - constant sound of buzzing and pump running - worse downstairs than up. Also it didn't seem to heat the house that well, only just comfortable. Was glad of the wood burner.
