Get a BER rating on your house. Then work on getting that rating up to A. Then consider a2w

Get insulating chief. Prob new windows too. I’m in the same boat as you except I’m starting at D but I don’t think it’s realistic.
Also, a2w is ideally to be used with underfloor heating or as an alternative, big ugly aluminium radiators.

Ok thanks for info

I looked at this but concluded (possibly unscientifically) that getting an older house (20 years old) up to the sealed standard that would make air to water a possibility was not going to be viable. Admittedly I was probably easily persuaded as I prefer to have the house open and airy, and wear extra clothes as necessary. I don't really fancy the 'sealed house' effect, however I was only in one - a show house for sealed systems - I did not like the sense of deadness in the air in spite of their built for purpose house and extensive air exchange systems.

Anyone got any info that’s gone through the process of getting air to water?

Yes, I just told ya. I’ve fitted a few retrofits. They installed new windows throughout, had walls pumped, insulated slab inside and a boat load of extra insulation in the attic. C2 to A2 is a sizeable jump.

Whats it costing you to date if you don’t mind me asking?

Purgative

Blues there are grants (of varying levels and criteria) through SEIA.

We did exactly what you're proposing 5/6 years ago through SEIA.


The process took a number of years:


- new windows and doors
- additional insulation attic
- cavity filled and external insulation fitted
- solid fuel stove disconnected from rads
- rads checked and serviced
- a2w installed


I love it. The house isn't airtight by any means although the criteria may have altered since we did it. The house is pleasantly warm, not roasting, all the time and we always have hot water.

I was the plumber fitting the Heatpump. My end was coming in around 10-15k. I’d take a guess at a further 20-30k for other bits

Try some crowd that only do heatpumps in your area. There’s a renewable energy thread on here that’ll send you in the right direction

You need a registered technical assessor who will go through all your options.
Don't go directly to heat pump installers as they will not have the required info to even size the heat pump and after all they are in the business of selling products.

Imo, your best bet is to have a full heat loss survey done first to understand exactly where / how the heat is being lost. This info will then inform exact improvement measures required and should also include heating solution options which may or may not include a hp.

Note, this is not a BER.

Don’t put to much faith in the BER rating.

Any link to that? Had a quick look and couldn't see it

Can I run underfloor heating on top of existing concrete floors and concrete over instead of digging up floors obviously doors would have to be adjusted.

You’ll have to put insulation underneath somehow

Could I not put insulation down first

To get an old house up to standard means a lot of gutting and a cost in the region of 50 to 60K. pretty sure there is a grant.

So going to get a company called eco efficiency to access the house to see what needs to be done anyone ever heard of them there based in Galway
