Have a "wandering run", creating new settlements on my way to abandoned ship. Currently at border Icesheet to tundra.
Swapped ProxyHeat and Heat Map for Celsius.
First of all, Heat Map has a prominent UI output for current outside air temperature so you can contextualize the cell/room temp. I miss that option in Celsius. I constantly need to hover inside and outside to see whats cooking.

I also switched to vanilla color coding since the mods color palette "comparing to lowest" doesn't help when green still means -1°C in winter and +20°C in summer and you still have to hover over each cell to see if you reached a sane temperature.

->After switching mods I had one very sweaty episode where my icesheet base sunk into the sea due to my modded heaters tawing the ice. Evacuated my pawns and everything valuable to my thankfully unaffected second base in tundra.
Yes, disabling that mod option would have helped, but it was an entertaining hassle. You warned me, I did it nonetheless, and it was messy fun.

Now I redesigned the tundra base with Celsius in mind. I have modded chemfuel heaters, the small one has heat pusher like vanilla campfire, the big one has 4 times the heat and no upper limit. I intend them to push enough heat to keep a greenhouse (Dubs Skylights and hydroponics with sunlamp) above freezing and to indirectly (over the floorways) heat the bedrooms. Also outdoors keeping trees alive in winter.

I also threw in Insulation + Patch to help.


Here is the catch: the same heat pusher, lets say the big chemfuel one

<li Class="CompProperties_HeatPusher">
<compClass>CompHeatPusherPowered</compClass>
<heatPerSecond>100</heatPerSecond>
<heatPushMaxTemperature>9999</heatPushMaxTemperature>
</li>

- overcooks the bedroom 8 tiles and a sandstone wall apart to over 60°C and burns everyone trying to refill it with 200°C hot air, despite 2x2 no roof above and outdoor temp -40°C.
Also autoignited the chemfuel the burned pawn dropped. But after deactivating your mods autoignation, at least that part was solved.
Still, the rooms way too hot. Outer frame has slate walls, heat pusher 6 tiles away from first bedroom, again slate wall, the whole bedroom (6x8 tiles) is too hot.
Uninstalling the heat pusher, opening doors and more roof tiles will still not help cool down fast, so I need coolers to help. In -40°C weather.

-can't keep the adjacent tile above freezing when outside in the same air -40°C, so my goal to keep trees growing fails. The heat pushers cell doesn't reach above 80°C and the next cell reaches barely 0°C.

-can't keep a radius of five tiles above freezing in a double insulated (sandstone + sandstone biomass wall) all roofed greenhouse, still the same air -40°C outdoors.

->Bedroom cooked, indoor and outdoor plants freezing.

-then in summer (outside around 10-15 °C) suddenly pushes half the greenhouse above 60°C, uninstall the heat pusher. Open roof, open doors. Tiles will stay hot for whole season.

Meanwhile the Vanilla heater in the same -40°C weather stands inside on top of double bed and can't even keep the whole bed warm. Royal bedroom 10x12, currently single slate wall. Have another big heat pusher outside in a 2x2 insulated room, connected with Vanilla vent. Doesn't help at all.

Maybe it's some wrong mod order? By now I have slightly increased the roof insulation value.
But what annoys me is the unpredictability whether the same heat pusher will cook me alive or keep me freezing.
