Positive input ventilation in a small flat. How cold?

agylk

After nearly 5 years of trying literally everything, I have made no progress in getting the air moving in my flat. The air  is stale and musty. Smells linger. Things aren’t too bad in the summer when the windows are wide open 24 seven (I leave a gap even in the winter which doesn’t help at all) but this is clearly not normal and not the solution because I can’t have windows wide open all year round. I have also had mildew problems in the past so I’m super conscious of preventing this now. Things rust due to humidity (I should add I live very close to the sea). Before anyone says to look for mould, I’ve had six different specialists here including a surveyor and no one has ever been able to find any mould. The final damp specialist said that sometimes the walls in a Victorian house like mine inherently smell because this single brick is wet and the render is waterproof meaning it cannot properly dry out. There is no sign of damp anywhere in the flat though. so anyway, I’m at a complete loss now and want to install positive input ventilation. All would be well and dandy if it wasn’t for the fact that in the winter, the temperature coming from the unit will be tempered by mere 2- 4°. Sure, temperature is slightly higher in the loft but it will still blowing cold air which I cannot turn off. So I wonder just how cold is it going to be? It’s probably less noticeable in a house but this is a small one bedroom flat. The flat is already super cold because I have three external, single brick walls. I was going to go for nuaire but these are out of stock at the moment and the guy who installs it suggested vent axia. Is it as good? Thanks in advance

You can have your unit with a heating element if you want it. 

Absolutely nothing wrong with Vent Axia.

Thank you. That is the one with a heating element. None of them actually heat I have learnt. They only just temper the air by a couple of degrees. Hence the problem. The heat recovery units are a totally different ballgame and super expensive to buy and run.
