I'd reckon the challenge preventing that gaining popularity is that apartment owners would not be permitted to put in the required duct work.Is anybody au fair with this or have any info on case studies - I'm guessing apartments with electric heating would have been a huge potential market,
That's a fair point, but I would imagine this would be a negotiable with the OMC, given that there are other reasons why you may need to open up a wall?I'd reckon the challenge preventing that gaining popularity is that apartment owners would not be permitted to put in the required duct work.
No direct experience but from threads on here and talking to a few friends in apartments, OMCs are reticent to allow even minor works, let alone allow multiple internal and external holes required for the duct work and that's before you consider placing the outdoor unit that might require planning in an apartment setting.That's a fair point, but I would imagine this would be a negotiable with the OMC, given that there are other reasons why you may need to open up a wall?
I was responding to your comments on why they were not a more popular retrofit in apartments and not your particular situation. However, with 4 houses on a block each face of the building will be the front or side, and so planning restrictions will be a factor.Just to reiterate this is a sort of a terraced (actually a back to back, well 4 houses together on each quarter) and not an apartment.
I know somebody who is having mini-splits installed in a couple of the larger areas of their house as a way of easing into an air-to-air setup, would that be an option for you? Get one just for the kitchen or living room and turn off the existing radiators in there.Just to reiterate this is a sort of a terraced (actually a back to back, well 4 houses together on each quarter) and not an apartment. There is up to 6.5m from the furthest point away from the boundary with each neighbour, so drilling holes etc not a problem.
Yes! Someone kindly suggested this to me last year, but it was a bit expensive to start up. All the existing radiators downstairs are old electric storage heaters and all are broken, so there is power sources if it is possible to duct through to near their wiring. The quote I got was 2.5k for just the large living room, the duct work of course could be re-utilised if its in an optimal position for airflow. Unfortunately the company who gave me the quote no longer seem to be trading.I know somebody who is having mini-splits installed in a couple of the larger areas of their house as a way of easing into an air-to-air setup, would that be an option for you?

The sides on my side lead into a walled off patio, so actually shouldn't really be an issue, but you are correct about limits on positioning for outdoor units.I was responding to your comments on why they were not a more popular retrofit in apartments and not your particular situation.

I did a retrofit of an air-to-water Viessmann in our house recently. To the point made in this video, the cost of the heatpump is only the beginning of the cost doing a project like this, maybe less than half the cost in my case. So if an air-to-air setup suits your house (a few large open plan areas) it’s well worth considering. The ability to cool the house might come in useful if we’re to have more hot days/nights too.This guy in the UK, recently switched his heating over to an air to air system.
He has a few videos about it.
Long story short, he is very happy with it.
Toshiba Air to Air Heat pump (A2A) - Probably one of the best heating systems you can install
And it cools! These are air conditioning units but they heat brilliantly. Quiet, gentle, heating your home with incredible efficiency without radiators. No ...www.youtube.com
Zenith, I'm looking to do the same (retrofit of an air-to-water Heatpump). Can I ask how much it cost you? And who did you use to do the install?I did a retrofit of an air-to-water Viessmann in our house recently.

Precision Heating (precisionheating.ie) are the distributors for them in Ireland, they were very good any interactions I had with them and will have no problem recommending some installers in your area if you give a shout. One issue you might encounter is that a number of installers have stopped doing SEAI heatpump grant installs because of the complexity of the paper work and the SEAI auditors rejecting grants because the house does not meet the spec (radiators too small in certain rooms, that kind of thing), which create a serious headache with the homeowner who is expecting to get a large chunk of money back from SEAI but is unable to do so without spending more. I'm generally fairly skeptical when I hear stuff like this from tradespeople, there's often other factors at play (like not wanting to pay tax but being forced to if a grant is involved, disinterest in doing things properly, unfamiliarity with sitting down in front of a laptop and crunching the numbers on heat loss per room or whatever), however in the case of the heatpump grant it does sound like there may be a legitimate issue there.Zenith, I'm looking to do the same (retrofit of an air-to-water Heatpump).

I like the Viessmann but I don't see many people who install them.
An air to water solution would mean having to install all the pipework and radiators from scratch so probably a lot of ripping up floors, maybe walls, not to mention system design as it would effectively be designing and installing an entirely new "wet" system. House could also do with more ventilation than it currently has in dry rooms & there's no mechanical ventilation in kitchen/bathroom where it should be. It seems like a good "fit".I did a retrofit of an air-to-water Viessmann in our house recently.

I was thinking that. Have other stuff to do first, and the multi fuel stove actually compensates quite a lot because of the design of the interior. It's going to be a while before I can afford it as have some other works to do firstTrying to research this too. Cant see anything yet which states clearly why air to air would be better or worse than air to water.
Air to air has benefit of use in summer- it's possible that public policy doesn't want summer energy demand when efficiency is priority.
Air to air apparently works well in our climate.
For my own situation, we have solar, so summer usage would be on days we have our own generation.
