* It's cold and we have no hot water until tomorrow...to make the situation even better, we called a guy to come and fix it two days ago. He replaced the filter and charged us about $70. Funnily enough, the problem persisted. He came back today and told us it'd be another $50 to replace the bulb...probably what was the cause of the problem in the first place.
I wasn't aware a filter effected the heating or otherwise of your water...it seems it doesn't given we paid to not have the problem fixed.
* Called the school, we're getting a new boiler (unfortunately tomorrow though).
