How To Heat Homes In Frostpunk

Keeping your population warm is one of the most critical survival mechanics in Frostpunk. This guide will walk you through all the methods available to heat your homes, from basic building upgrades to advanced heating infrastructure. Whether you’re just starting out with tents or managing upgraded dwellings, understanding these heating strategies will help you maintain your citizens’ comfort and prevent discontent.

Understanding Your Starting Dwellings

When you begin your city, you’ll start with basic tents as your housing structures. These provide minimal weather protection and are the least efficient at retaining heat. As you progress, you can upgrade to better housing options that offer superior insulation and temperature regulation.

Researching Better Housing Structures

To unlock improved housing options, navigate to the technology tree and select the right-hand tab labeled “Food, Health and Shelter.” This section contains all your residential upgrade options.

Bunk Houses

Bunk houses are your first major upgrade. These dwellings accommodate 10 people and provide adequate weather protection. Compared to tents, they offer significantly more insulation, making them more efficient at retaining heat.

Houses

Houses represent the next tier of housing and provide even greater protection from the weather than bunk houses. They are substantially more insulated and will keep your citizens warmer with the same heating infrastructure.

Passive Heating Upgrades

House Insulation Technology

One of the most cost-effective heating improvements is researching house insulation technology. This upgrade makes houses one heat level warmer without requiring any additional infrastructure or resource consumption. Essentially, it’s a free heating boost that only requires unlocking the tier 1, tier 3, and tier 5 research tiers under the Food, Health and Shelter category.

Monitoring Your Home Temperatures

To check the current temperature status of any home, click on it and hover over the temperature gauge. This will display a detailed breakdown of how your building’s temperature is affected by various factors.

For example, a typical heated home might show:

Base temperature penalty from weather: -6

Building insulation bonus: +3

House insulation technology bonus: +3

Heat zone bonus from steam hubs: +4

Using Steam Hubs for Active Heating

What Are Steam Hubs?

Steam hubs are researched under the Construction category and represent a major advancement in heating technology. When powered by your generator, these contraptions create additional smaller heat zones around them, extending warmth across your city beyond what building insulation alone can provide.

Steam Hub Coal Consumption

Each active, unmodified steam hub consumes 3 coal per hour. This is a significant resource cost, so you’ll need to balance heating needs against your coal reserves and production capacity.

Placing Your Steam Hubs

To build a steam hub, select it from the construction menu and place it on a street location. Your workers will automatically begin construction. Once active, the steam hub will create a massive heating area around it, affecting all nearby homes and buildings.

Operating Hours

You have flexibility in how you operate your steam hubs. You can schedule them to run only during evening hours (such as 6 PM to 8 PM) to conserve coal, or keep them running 24 hours a day for maximum warmth. Adjust your schedule based on your current coal availability and population needs.

Advanced Steam Hub Upgrades

The technology tree includes several steam hub enhancements under the Heating category that will improve your heating infrastructure’s effectiveness:

Steam Hub Range Upgrade

This upgrade increases the radius of the heating zone created by your steam hub, allowing a single hub to warm a larger area and affect more homes.

Steam Hub Efficiency Upgrade

The efficiency upgrade reduces the coal consumption or improves the heating output of your steam hubs, making them more cost-effective to operate long-term.

Combining Heating Methods

If your homes still aren’t reaching comfortable temperatures, you can combine multiple heating approaches. For instance, you might upgrade to better housing structures, research house insulation, and then position a steam hub nearby. When you click on the home, you’ll see the cumulative heating bonus—in this example, adding a steam hub resulted in a +4 heat zone bonus on top of all other improvements.

Summary

Heating homes in Frostpunk involves a combination of passive and active strategies. Start by upgrading from tents to bunk houses and then to houses. Research house insulation technology for free heating improvements. As your city grows, invest in steam hubs and their upgrades to maintain comfortable temperatures across your entire population. Monitor individual home temperatures and adjust your heating infrastructure accordingly. With these methods, you’ll keep your citizens warm and content throughout even the harshest winters.
