@toodles even more impressive then. Mine is set at 20c 24/7 on a WC curve on an Auto Adapt setting. Likewise, my installer at service is impressed at how clean it is but it should be as a total install with new pipework and radiators.  As said I need a review by a Heat Geek.

Not yet – we're still liaising with him trying to set a date, but it'll almost certainly happen next month (April).

@morgan Mine was a retrofit but did receive a good powerflush during the installation; 8 new radiators plus a dual fuel towel rail were fitted and 2 older radiators remained. All the other pipework was replaced as we were having a totally new DHW system (Sunamp Thermino) separate to the heat pump and the old cold water storage from loft was removed too. Rising main feeds everything via a water softener now. Regards, Toodles.

Love the grammatical attention to detail in your post construction. 🤣

I'm a word and grammar geek. Data is traditionally considered a plural noun, so "here are the data" is grammatically correct. In modern usage, "data" is now treated as a mass noun (like "information"), so it takes a singular verb form, as in "here is the data." 

I just sounds odd when you say "here are the data" out loud.

Apologies for the brief deviation away from the topic. As you were.

@editor That’s absobloominglutely fine Mars, I’m one of those annoying sods who constantly shout at the radio (Radio Four mostly but increasingly, Radio Three as well these days!) for use of poor enunciation, pronunciation, and grammar! I feel that those in such positions of influence on how we speak should be setting a good example. Oops Sorry! I’ll dismount my soapbox now and get on with preparing lunch… Regards, Toodles.

One datum, many data. That is the grammatically correct form. However, English is a living language and so, as @editor says, data as a singular noun is no longer incorrect; it has been made correct by common usage and understanding.

Interesting that language is one of the few instances where many wrongs do indeed make a right.

This is the sort of English up with which I shall not put!

Have you considered wall mounting it. I'm in a similar 1915 two bed mid terrace. On the back wall of my house there isn't a window for the first floor, so there was space to mount the ASHP, the flow and return follow the gutter line, round the side of the house and into the loft space where the hot water tank is. See the pics.

@ecobaker Thanks for the pictures! Did you have any planning application challenges with that? Just thinking from the visual impact. 

I think getting it past the partner test would be harder than the planning application!

@samiebon1 No complaints or problems, there is a big enough space between it and houses behind so sound is not an issue. Lots of the houses a long here have significant extensions into their back yards, I don't have any, so I imagine if they are all okay the heat pump would be fine. Although I didn't do a formal planning application.
