Initially I was contemplating a standard wood burner with back boiler and radiators but then considerd the freezing water effect on the system during the colder months when the flat is empty.
Do like the Romas (well... Poles) do.
Install standard low-tech central heating system based on water. And dry it up before winter. The additional cost is about 3.50PLN (for an extra valve)
At the moment I am thinking more about a wood burner with hot air delivery system but am not sure as to it's effectiveness and the possible problem of dust being blown into each room.
For some reason these system are not very popular in Poland. And I think to know why: cost and effectiveness. I would not recommend this solution.
On a side note does 5000zl for 4 good sized double windows
The Polish windows are quite different than those in the UK. Take under consideration that -20C is nothing uncommon in Poland during the Winter time.
Worth to know:
- outside glass covered by the thin layer of metal will reduce costs of heating greatly
- three chambered profiles are a minimum
- argon filled gap between the glasses are OK
- three sets of gaskets (instead of standard 2) are much more effective.
