Nearest without too much disruption: ‘Heating Pump’.
 
But will give it some more thought. Toodles.

Seriously? This device "pumps heat" into a dwelling or space what is there not to like? LED bulb, why add bulb it is a Light Emitting Diode surely (don't call me Shirley) not that difficult. I don't believe a boiler boils actually, well I hope not maybe it should be called a water warming device with a pump that makes your house warm. Oh no that could be confused with Heat pump! OK I'll get me coat!!

Cue the 'ignore climate change and it might go away' lobby running articles telling their readers that heat pumps have been cynically rebranded by the left wing wokerati in order to fool us into thinking that they are a good idea. 

Heat pump(s) is fine - most people know what they are these days.

Homeowners? What about tenants? Housing Association etc...?

I think the 'owners' bit needs to go. 

You know my views on social class and climate change policy! Just consider me the forum commie. ✊🏻🫢😂

I think the term has entered into the English vocabulary now and it doesn't need to be descriptive - rather like a hoover.

@ianmk13 That just leaves a total vacuum in my mind…
When I consider all the ‘modern expressions’ that have been foisted upon us (example. ‘I was like...,’ frinstance), I really feel that the public in general should accept ‘Heat Pump’ - it is accurate, short and self explanatory. Toodles.

@toodles Like Cycles per sec becoming Hz, Centigrade to Celsius. Finisterre to Fitzroy Perfectly descriptive terms IMHO.

@jancold No, I had in mind ‘modern idioms’ mainly; yes, I am showing my age! Ancient Toodles.

Like many here I read the OP and immediately jumped to the conclusion any renaming was unnecessary. Nonetheless, not wanting to be too quick to judge I have taken the time since to have a bit of a think.

Does "heat pump" say what it does? Yes, I've decided it does. It moves heat rather than generate it, so the name is a fair reflection of its job. It's also a name that uses two very readily understandable words so wouldn't put people off due to excessive jargon, methinks.

Does the name allow people to understand how it works? Perhaps not. In some ways it's too simplistic a name for that purpose. Nonetheless, people don't necessarily want names for that purpose; how many people refer to their car's tachometer as a rev counter? Not accurate but common currency nonetheless.

Do people need or want to know how a heat pump works in order to be inclined to buy one? Hmm. Much more difficult question to answer. If someone doesn't understand the principles of a heat pump, they're unlikely to understand how their fridge works either but I'll lay odds they own at least one of the latter. The problem is that they might not know how a fridge works but they have complete confidence that it does work and there, I think, hangs the rub. Heat pumps have been denigrated by several different groups for several different reasons and so home owners do not have the same confidence, and I don't think a name change will fix that.

Alternative terms? I did try to think up at least one serious alternative but every time I thought about how they work I found a streak of whimsy creeping in. They take heat from outside and deposit it in the home so should one be called a Garden Cooler? They work like a fridge in reverse so should one be called a "Defrigerator"? If they take from the outside to give to the inside, perhaps we go the whole hog and call one "Robin Heat".

@majordennisbloodnok Perhaps in a way, we are likely to be the wrong people to ask this question - we know what heat pumps are and what they do. We would probably accept a name such as ‘discumbobulator’ as we know that the device appears to Joe Public as a strange device that could keep us warm in our homes.
I still feel there is nothing wrong with ‘Heat Pump’ but, if the general public who maybe don’t subscribe to the likes of RHH are at a loss as to what a heat pump is or does, perhaps the government should allot a few £M to a Public Relations organisation to consult the man and woman on the 49 bus and ask and then educate them!😉 Regards, Toodles.
