The oil furnace is the auxiliary heat at Mist Cottage, and it wasn’t kicking in when it needed to.
The first thing we thought of was the thermostat, but it seemed to be working as expected.
When the temperature drops 2C below the target temperature, the oil furnace is supposed to come on to bring the interior temperature up to the target. This doesn’t happen very often when the heat pump is heating the house, as it kicks in if the temperature falls by 1C. It is only when the weather throws a quick and extreme temperature drop at us that this whole sequence comes into play.
Attila had some ideas, and started with the simplest, checking all the wiring that was visible. Sure enough, one of the connectors was dislodged! He secured the connector, turned the heat up to 27C (from 21.5C) and bingo, the furnace instantly began to do what it is supposed to do! I turned the thermostat back down as soon as it was a sure thing that everything was working as it should.
This morning Attila looked very stern minutes after he got out of bed. He was pondering and worrying over the furnace issue, as well he might. That worry has now been allayed.
At some point our oil furnace will need to be replaced, but we are in no hurry to do so. When and if the oil furnace fails, the new furnace will be a natural gas furnace, and when the natural gas supply is connected the electric hot water tank will be replaced with an on-demand hot water heater. If we are lucky, this won’t ever be necessary. Dollars to donuts though, at some point the heating system will need updating, even if it is only because the insurance companies refuse to cover a perfectly good oil furnace and tank. Time to open a savings account for a new heating system, start now and hope for the best.
