@josejo thanks will check it out.

@keithb If you would like to start a thread describing your system and the current problems Im sure someone here will be able to help.  Costs will of course be highest in Dec/Jan/Feb, but should be comparable to gas or oil if you average over the year. 

The most important things to minimise cost are to run 24x7 or thereabouts with weather compensation turned down to the lowest value consistent with heating the house.  If you run it like a boiler and/or dont have weather compensation properly adjusted it will cost more, possibly a lot more than if run correctly, and be less comfortable.  Fortuitously the right way to operate it for efficiency is also the most comfortable and if you get it right (which may  take some tweaking) you should end up with heating that is much more comfortable costing about the same to run.

If you would like to start a thread describing your system and the current problems Im sure someone here will be able to help you achieve that.

I would also recommend you read this introduction to help dispel any myths and provide some background.

Flawless, by John MacIver, Seaforth Heating and Plumbing, on The Isle of Lewis and Harris: (an entire team and) he were stellar; so efficient, quick, thorough, caring, and a good listener! Gold.

I love being warm now, after 3 years of being cold in Scotland, as I moved here from Maui, Hawaii, and had no idea how to deal with staying warm. Now, I am cosy and grateful on the Isle of Great Bernera, (next to The Isle of Lewis, Outer Hebrides, Scotland, across an 8-sec bridge).

I am loving my Mitsubishi Air Source Heating. Flawless.

A few spots on many walls were left a mess, but "walls are not on our docket" is a thing here. It is a Council house that was neglected for 19 Years, so I named it

Taigh an Eala, in Scottish Gaelic, AKA "Swan Nest", and this ugly duckling-near-ruin is evolving slowly, gently and truly into The Swan!

It is an HHP house, Hebridean Housing Partnership, LLC. "We don't paint." is also their thing. And, so I will learn. Ha. 

Being warm makes me happy, and feel generous, so I send you...all:

All the Love in the World, 

Claire

@claireisamazing, that’s got to be one of the most positive, uplifting and genuinely refreshing posts we’ve had on the forums in a long time.

It’s easy to get bogged down in the problems, complaints and horror stories (and rightly so when things go wrong), but this is exactly what it looks like when everything just works… good installer, good system and a homeowner who can finally enjoy the result.

There’s something quite powerful in what you’ve said about simply being warm. That’s the whole point of all of this and it often gets lost in the technical noise. Three years of being cold to suddenly feeling comfortable in your own home is no small thing.

Also love the “Swan Nest” transformation… there’s a nice parallel there. A neglected house slowly being brought back to life and a heating system that actually supports that journey rather than fighting it.

Credit where it’s due to John and the team as well… that’s how this industry should look when it’s done properly.

And please do stick around and keep sharing updates as things evolve. Posts like this help balance the narrative and give people confidence that it can be done right.

@editor Thank you. I joined because I really liked your presence and enthusiasm, and guidance. Thank you for caring, and supporting people having hope, a better experience, and learning here.

It is so nice to be satisfied. I make a lot of Complaints, when necessary, so this is wonderful, being warm and happy.

All the best to you,

Claire
