Yesterday I discovered that water was pouring out of the dehumidifier/air exchanger thingy attached to the furnace. Repair guy is coming tomorrow. When I called the repair people, they said that for this type of repair the system has to be turned off for at least 24 hours before it can be worked on, in case something has frozen and needs thawing.

It's now 27 C in here and I'm finding it a wee bit warm in the house. Poor Mr. Ivriniel is miserable. If he had his way, the house would be 15 C all the time. I swear he's a Sebacean. He actually has trouble functioning at this temp.
