Why doesn’t Mr Unit Heater work?
And why does he make noise?
This unit heater was installed in a room in a building which has convectors in most rooms. (It was a convent and most of the rooms are small bedrooms). It is Is in a corner sun room that is currently used as an office. The person working there says when it goes on it is hot then cold. And it bangs a bit.
The steam system is controlled by a tekmar 279 with a few space sensors. I assume the unit heater is blowing cold waiting for the boiler to start up it’s cycle.
Water hammer – There is no drip on the steam. And not much of a leg on the condensate. I’m don’t know about putting a thermostatic trap on a unit heater either.
