He doesn't look well to me in this video.

A failed Plumber, that’s now a Builder??!!!
Gas Safe kicked him off their Register, he thought he was bigger than them. A self-promoting narcissist, just in it for the freebies & money.
One of, the now many, Ponce Plumbers!!
He’s talking shite about ASHPs but the way.

The last Labour government had commissioned a special report into why heat pumps don't appear to work in the UK.
Poor installation techniques was one of the thoughts back then as was poor insulation of our homes, however, it was also thought it could be the UKs climate?
Alas we never got the report because it was scraped as an austerity measure by the newly elected Conservative government (pity because it could've been very interesting reading).
Some people think heat pumps are fantastic whilst others hate them, so for me the jury's still out on them.
Roger has made a few good points about the negative side of them though.
Noise being a big minus point (especially the 4am start up needed in winter to get the hot water up to temperature before the heating kicks in). He also points out that they work best in the summer (when you don't really want to heat your house) with a cop of 3 and then when you need your heating the most during a big winter freeze up the cop drops right down to 1 and the units running 24/7 just trying to keep pace.
The "buffer-tank" he mentions though is a bit old hat nowadays and in my experience they only were used on the very first installation's when ASHP were not as good as they are now!
Poor Rodge, he seems to have fallen on hard times these days!

As someone that has installed ASHPs, Geothermal HP & Solar HPs. The technology is just the same, it’s a Low Temperature CH system, so operates at the optimum 30-40degrees Flow Temperature & a Delta T of around 7-10degrees. The system generally requires a High Flow Rate too, running 24/7 on Weather Compensation Controls.
With the very best emitters being Under Floor Heating. Standard steel panel radiators at 8 times the size of conventional Gas system radiator, may be required!! K3 radiators are not uncommon.
Of course it goes without saying that in the UK, the houses having HPs fitted should be super insulated. Without good U Values, you’re farting at thunder!!
Though, there’s very few days, even in the middle of Winter that are very, very cold. We can get them, so a supplementary form of heating is always recommended.
Anyone remotely interested in sharing my experiences & knowledge, please send a £50 note to the following address, along with your telephone number & I’ll never contact you, to give you any further insight👍👍

Hydrogen is by far the best option, simple to produce & distribute via the Natural Gas Network, all be it the Network would require modified & ungraded. Obviously, Steel Pipes & hydrogen are not good Bedfellows. Currently, there’s some Nat Gas supplies containing 20% hydrogen. Many of you young Pups will not remember Coal Gas or Town Gas as it was loving referred to, it contained lots of hydrogen. Local area Gas Works producing gas for entire Towns & Cities. Nor will you remember the conversion to Nat Gas in the late 60’s early 70’s. Yes, logistically it can be done, with many existing boilers only needing mirror adjustments for conversion to hydrogen. Don’t get me wrong, Heat Pumps are great, but HP systems need to be careful design & to be correctly installed. So given the poorly insulated housing, the inadequate CH systems & with an average home only have an 80Amp Leccy supply, it’s really a non-starter in many, many situations. |

Well the hydrogen car is being tested up here www.bloomberg.com/news/articles/2021-09-08/this-village-in-england-is-already-using-hydrogen-to-heat-homes Now a fill from empty is matching the petrol and diesel times and the cost are matching so why they want the electric cars beats me with all the hassle. apple.news/AHmOgn51CSvK8JZsikolHjA |

I couldn't get that 1st link to open battle but assume it must be a report into testing hydrogen fuel in cars and I can well understand the problems the other fellow was having getting his electric car charged up on a long run.
Maybe electric cars will only ever be suitable for folks who only travel short distances?
It now seems to be assumed that the number of vehicles on our roads will go on increasing with our ever expanding population with just a change in what we can run them on?
Past thinking was some kind of monorail system would eventually replace our own private vehicles when the fuel runs out?
Back to Heat pumps and something simple to get our heads around is that ASHP/GSHP are both "Poor Sources of Heat".
Whilst all the fossil fuels produce a "Good Source of Heat".

Back to Heat pumps and something simple to get our heads around is that ASHP/GSHP are both "Poor Sources of Heat". Whilst all the fossil fuels produce a "Good Source of Heat". I think we’ve an internal thermostat in this country, something I call the ‘Hearth Effect’. Unless it’s glowing red & we can feel that radiant heat, it’s not working right!! Low Temperature Central Heating is Heating Homes in the UK very successfully, living with Underfloor Heating is very, very comfortable. It’s mainly a Radiant Heat, that limits the amount of radiant heat our body loses. As I said, a HP will only produce a Low Temperature Heat. |

I first came across a ufh system in a holiday cottage in the 90's. I knew about the principal of how it heated the slab but I was convinced for a while that it was not working properly as the floor didn't feel warm.
(Even though, the rooms in the place didn't feel cold).
I think most ufh owners have that "is it working properly?" moment at first.

Scotland was miles ahead of the rest of our UK when it comes to UFH. I installed my first system in the late 80’s. Designed & Installed 100’s of systems. |

UFH had a big run in the 70s too, mainly in care homes and residential living units.
It worked well for around 25 years after which the pipes started to corrode and leak. The floors then had to be dug up to make a repair.
Eventually the UFH systems got replaced with combi's which were installed in each property thus supplying heating and instantaneous hot water to each unit.
Interesting in how we now seem to be going back to this system (UFH) plus the idea of stored hot water is also making a return, albeit it's now all mains fed.
Circle of life?
