True, but I understand the shape of the barrel, because it doesn't allow for 2nd/high tier seating, reduces the efficient use of the hot air that accumulates near the ceiling. Seems like I need to read up on this! Thanks for your input.

@pstunt - did you install a Polhus sauna in the end? If you did, are you happy with the quality and the installation/after-sales experience? We've just received a quote from them for a 2x2m sauna, hence the question.... Thanks.

thank you for this useful resource, @JamesP - I'll have a close look.

I understand the rounded ceiling of Barrel Saunas make them a less effective shape than a cube shape - @SteamyTea would you have an opinion on this given your experience? It also seems that the Polhus quote of £5.5K + installation for a 2x2m sauna might not be too much...

Thanks for your prompt reply @SteamyTea. I should have mentioned the budget of £3K was without installation and the cost of utility connections.... What would be a reasonable budget for a 2x2m sauna? And, can you recommend an installer near TN3 (if we were to buy a modular/flat-packed one)?

Hello - we want to install an electric outdoor sauna on a 3.5m x 3.5m level composite decking platform. The sauna will be 2m x 2m with a timber door and a single large (1500x1500mm) plate glass window. Please see attached hand-sketch and the finished look we'd like. Research on the net suggests a wide range of prices, but mostly £5K+. Our budget is closer to £3K. Would anyone know of an experienced local builder (near Langton Green/Tunbridge Wells/Kent) who might be able to build an outdoor sauna for us? We'll have equipped the sauna platform with single phase electricity and water source (for a cold, outdoor rustic shower). Any and all pointers will be most useful. Many thanks!

Hi @Robert Clark- can I ask how much you ended up spending for the supply, installation, and commissioning of your AHSP. Did you go with a ~12kW Mitsubishi ahsp? For a 4-bed house in Kent (approx 240 sqm with a double-height entrance hallway), I've received various quotes for between 12kW-16kW ASHPs. In fact, GreenHome Technologies has quoted £24K for a full package (supply, install, commissioning, excl VAT) - it seems a touch too high?

@Gone West - can you expand on this thought please? Would a plumber be able to specify and design such a ventilation system... ? Or, is it a specialist arrangement? Thanks.

@pstunt - that's a beautiful and large home! We are also considering using Pagurek standing seam roof. Is your roof installed and are you happy with it? And did the installation of rooflights cause any issues?

@PeterW Hoping the ASHP will serve UHF and hot water (there's no Gas on site, just electricity). Architect has been asked to take a fabric-first, low-energy, high-insulation approach. Hoping to have the uValues tomorrow.... will share when I have those numbers.

Hello David! We're embarking on a barn conversion project - it'll be our home in the country, so my husband and I will likely be there over weekends with the children and partners joining us possibly 3 times a year. We're seriously looking at NOT installing an MVHR - not only because of the cost, but to [a] minimise energy wastage (there'll be largely 2 occupants using the 4-bed house intermittently), and [b] keep things low-tech as much as possible. We will, however, have an ASHP, UFH, and solar PV. I've read your post with keen interest. - We'll install wall vents and good extractor fans in bathrooms and in the kitchen, as you suggest - But, are reluctant to bore holes into triple glazed windows for trickle vents My question is, how can we achieve the 1 ach if we're not using mechanically driven ventilation? Should we consider a Positive Input ventilation (PIV) and fans (for the hot days of the summer)? Thanks in advance for your input!

Thank you for that! So you got your MVHR (designed, supplied, installed and commissioned) by the Green Building Store? As it happens, I'm speaking to GBS about our ASHP, UFH and MVHR as well.... good to know you were happy with their service. Thanks again.

@Thorfun - can I ask who you eventually got to do the design of your MVHR? And, if you had someone install it for you (we'll be building in Kent, not too too far from you). Thank you!

thank you for that tip, @JohnMo!

Thank you, @JohnMo and @Tempfor the helpful tips! Have a good evening.
