gramos Posted November 16, 2021 Share Posted November 16, 2021 Kalispera , from Kefalonia , where my house build is in progress . I just found the forum when researching woodburning stoves for this type of house . It is a PH build , in principle. Link to comment Share on other sites More sharing options...
Russdl Posted November 16, 2021 Share Posted November 16, 2021 Kalispera and welcome. Has the PHPP been done? You’re not going to need a wood burning stove I’ll wager. Link to comment Share on other sites More sharing options...
joe90 Posted November 16, 2021 Share Posted November 16, 2021 Welcome, at least your weather will be very different from ours?, I guess overheating may be more of an issue, at least insulation works both ways and PV fir you will deliver more (unless I am completely wrong).

I know you can ski in Greece but Kefalonia seems not to get temperatures below freezing at any time. mostly down to about 5 deg C in the coldest month? Keep posting as interested in what you are doing. All the best with the project. Link to comment Share on other sites More sharing options...
Iceverge Posted November 16, 2021 Share Posted November 16, 2021 welcome welcome. It’s difficult to get proper room sealed stoves outside germany and austria. Here’s one site. Search “dibt” room sealed air supply. https://www.kamdi24.de/kaminofen Remember you will need an excellent flue system also to get good airtightness. I was all set to go down this route but I couldn’t get good installers and good products for a reasonable price. I have little regrets about not bothering as we couldn’t have gotten as good an airtightness result with a stove. Link to comment Share on other sites More sharing options...
gramos Posted November 23, 2021 Author Share Posted November 23, 2021 Kalispera and thank you for the welcome . A little more about our project for those that find it interesting . It was difficult to find any interest or even knowledge of Passive House criteria on this Greek Island but we are on the way ! The house is designed and specified to keep the heat out in the hot summers as much as retaining warmth during winter , insulation being key . Timber frame is understood here but 90% of houses are built using concrete frames with hollow brick infills and up until recent construction law changes, zero insulation ! Concrete is heavily re- enforced and foundations are substantial and deep Kefalonia sits very close to the Aegean Plate which is being subducted by a north moving Africa plate, up to 20mm p.a. Therefore it is accorded zone 1 seismic risk , the highest . Earthquakes are common , a 4.8/ 5.0 last week ! the buildings here are almost all built after the major seismic event in 1953, which destroyed the majority of buildings the island , so the building control is very strict . As regards the stove , I am looking at 5 +kw to heat the whole house utilising 2 x centralised mhrv units . the house has 2 x lofts with a cathedral ceiling dividing them so two units are needed as there can be no crossover ducting . we burn oak and olive wood so high calorific output is achieved .

Iceverge Posted November 23, 2021 Share Posted November 23, 2021 Here’s an example of a passivhaus in your climate. It’s 8w/m2K heating load is tiny. https://passivehouse-database.org/index.php?lang=en#d_5214 If you build a passive house and put a 5kw stove in it will be unusable for most of the year and only then probably with the windows open. Did you run PHPP on your build, I suspect cooling is a much greater issue. 1 Link to comment Share on other sites More sharing options...
gramos Posted July 4, 2022 Author Share Posted July 4, 2022 I hope this update will be of interest? We have finished the build but for some small details 😃. I bought a modern stove from Kratki , it will wait for winter before connection , it is 35 C here ! I have 2x A/C units fitted so am working in a comfortable 25 C . I have installed a full off grid PV system which is running the A/ C and there is still a surplus of energy 😁 . In fact the growatt inverters shut down occasionally as we are not using enough of our generated power , (open to suggestions here ) The build was challenging for the locals ,who know not the world of Passiv Haus , but we have ticked most of the boxes . It took exactly 1 year to build , on a Greek island , so much more of a challenge especially during the covid situation. The house retains the cool temp overnight , it's a pleasure to walk in at 0800! 2 Link to comment Share on other sites More sharing options...
JohnMo Posted July 4, 2022 Share Posted July 4, 2022 Do you have an immersion diverter or timer, this will use some of the surplus PV power to make DHW. Link to comment Share on other sites More sharing options...

Heat water, or the swimming pool, a fan heater outside. Power sewage works or water purifier if you have them. Charging batteries would be best. Do you still get a decent payment to feed into the grid in Greece, or are you off grid because there is no grid on the island? Link to comment Share on other sites More sharing options...
CharlieKLP Posted July 4, 2022 Share Posted July 4, 2022 Kalispera! Enai poly kalo! (Sorry for the lack of Greek letters lol!) I really love Kefalonia, would be my dream to build in the Ionian islands (I’ve sailed around there a few times). would love some more images of your house. How was the planning process? Well done, amazing really. I had a friend who was an architect there, so jealous. One thing I’ve noticed is so many houses are half built in Greece, what’s up with that.

I asked a waitress that one night in Corfu. She said it was the way to build in stages as and when you had the money. Particularly if you rely on the tourist trade. I recall being amazed at them using pumped concrete. Edited July 4, 2022 by Onoff Link to comment Share on other sites More sharing options...

I know some countries you can avoid paying local property tax on unfinished build so houses often have a not quite tiled roof somewhere that never quite seems to get finished Link to comment Share on other sites More sharing options...

FWIW My comment above about non-finished property was about the ongoing property tax (i.e. council tax), nothing todo with VAT rebate. Link to comment Share on other sites More sharing options...
