HRV - installed, home value increased?

My house is old. 1960 old, well, er, *cough* thats not that old really. erhm. Anyway.
This winter the condensation has been particularly bad and the amount of mildew and mold growing in the place has just been a nightmare. Washing the windows and net curtains is like an exercise in level 1 decontamination.


I JUST COULDN'T TAKE IT ANYMORE.

So I went hunting for a dehumidifier, they were expensive and power hungry. Just like me! I can barely afford me let alone a dehumidifier as well, so resigned to weeks of saving I went home to dream about my fantastical dehumidifier.

That night we received a mysterious phone call around dinner time, the universe had heard my call for a drier home and had sent the HRV telemarketer! We agreed to let them look at the house and two weeks later we have a ventilation system. Top number is roof temp, lower number is house temp, bottom number is kept high to make sure any available heat is pumped into the house. Of course when its cold in the roof it just switches to ventilation mode so we don't freeze our nubins off.

 It cost a packet, but they have a payment plan. First item we've bought on credit since ...since.... our car the one we had before this one? Anyway. Here we are indentured to the man. But our home is dry and awesome. As a nice bonus everytime the roof temp gets above the house temp it pumps all the warm air down. It was a balmy 18 degrees in our house today!  Breakout the short short and TANK TOPS!
