Air to Air with hot water systems

Just be careful, I bought a single one of those and the fan motor in the indoor unit failed after a year. When I went back to Buy it Direct for warranty the first thing they asked for was the installation cert. Course I didn't have it, so that was the end of that - Had to buy the replacement fan. The I had to drain down the system and get it refilled. It would have been probably cheaper to throw it away and get a new one.

That's a bit vague though, isn't it? For me it would be relevant to get:

"Air to Air heat pump system

This system distributes heat through air units. They do not provide hot water.

Apartment/Semi-Detached/End of Terrace/Detached/Mid Terrace €3,500"

Previously I was told on this forum that a couple of mini splits wouldn't get me the subsidy. Why not? If not, what does get me the subsidy? A single pump with multiple indoor ventilation units? How many, is 2 enough? Good to know that you don't need to heat water as part of the system. I can also not find that it has to replace your current heating system in that link

@Jonathan I think. A list here but some Mods aren't active anymore since the upgrade. https://www.boards.ie/discussion/2058234282/list-of-forum-mods-and-category-mods-posted-22-02-2022#latest

End what's your plan when the gas boiler is end of life?

Ah ok, now I see why you are not really thinking of replacing it. Mine is 10 years old and high efficiency condensing boilers don't last that long, so I'm in a different game. I want to not replace it with anything fossil fuel when it dies

BTW bathrooms are ideal for heating with far IR panels. You can get ones that have a mirror finish (to replace your existing mirror) and the direct heat from them is very pleasant in a bathroom

Does anyone know if you can double up on the grant?

I got A2W Installed under the prior value (3.5 instead of 6k grant).....

Now considering an split A2A for cooking in the summer... The grant would make a serious dent in the cost.

Would you care to share the details of the system, how many ventilation and pump units, total cost of install before and after subsidy? Did you decommission your fossil fuel burning system?

I'm sure it is good value and a good investment as your friend installed it. Best of luck with it!

Personally I want to get rid of my gas boiler and radiator central heating altogether and go electric air to air. But only if this is financially viable, as in not much more total install cost than getting another boiler.

We have a Mitsubishi system in the office here. 3 floors, split.1500sq ft on each floor. Works to -5f (we also have gas as a back up).

heat and cooling in summer (very much needed) our building is OLD 1800s. Works perfectly and was installed during the redesign 4 years ago.

the monthly running costs are at most 300$ during cold periods for the whole building.

I installed air to air in my home in Ireland also. One wall mounted, does the whole house. Also keeps the house dehumidified (again older home) wifi controlled) Oil as a backup.

the house here uses gas and electric for heating and cooling was replaced with super efficient boiler in the past 4 years saving 70% gas costs and 60% in electricity.

obviously ALL properties have has insulation upgraded wifi has been added to all to save costs when not at home/away/at work.

air to air is a good alternative to air to water imho. Easier to instal and expand. Running costs for me are not that much.
