im building a new house(after five year wait)but new building regs are for for a house that is as airtight as possible.so have come to conclusion the only way to ensure proper ventilation is to install a HRV unit. has anyone have one installed,?how is it working? all the suppliers asure me theirs is the best system available.they all seem to be around the 5000 euro mark.can anyone recomend one over another?
