Behaviour experts say misinformation shared in media and by other stakeholders is impeding uptake

Just reading this, thought I'd share my own experience of looking into a heat pump boiler. Our current gas boiler is coming to the end of its life and having swapped my gas guzzler for an EV at the beginning of last year (2024) I thought I'd look into getting a heat pump.
We live in a modern (built in 2014) semi detached, with 12 radiators in total. Nothing too excessive or unusual.
We were quoted £13,000 for installation, which with a £7,000 government grant meant we'd pay £6K. For comparison purposes, we've been quoted £1,800 for an ultra efficient gas boiler replacement.
The real killers for me in terms of the viability of heat pump boilers were: we needed a 2m (high) by 3m (wide) by 2m (depth) space on an external wall to the house for the actual heat pump unit. Now actually this wasn't the real killer for us because we've got a large garden and we could have accommodated it but it works have been a bloody eye-sore and still taken up a fare chunk of land....but the absolute killer was we needed a 2m by 1m water cylinder inside the house. That's a huge water cylinder and we didn't have a suitable space for it so they said the only option would be for us to get a quote to convert the void in our roof into a loft strong enough to accommodate it and once done they could then install it. But even then they said they'd struggle to get the cylinder up the stairs into the loft area and so theyd need to get their technicians to arrange a second site visit and even if they green lighted it as possible we'd likely be quoted additional installation costs over and above the £13K and the cost (and stress and mess) of the roof void/loft conversion. At that point we abandoned the entire exercise.
So I don't agree that there's misinformation about heat pump boilers. From my own experience they are going to be completely impractical and overpriced for a lot of people and properties in this country.
Wasn't a killer for me either but the government trying to say news articles stating that heat pumps work less well in the cold are misinfornstion is in itself misinformstion. Heat pumps work by ingesting air and heating it. When the source air is colder that process is obviously less efficient. It's just a fact. I actually already have a heat pump tumble dryer and it's not as efficient at drying in winter as in summer meaning we sometimes have to put it on a second cycle for large loads. That's because the air it is ingesting to start it's heating process is colder and so the resulting heat the clothes are subjected to is also therefore colder.
And that's from someone that genuinely wanted one to be greener.
