The Cold Truth: What Freezing Weather Changes
When outdoor temperatures plummet, a system that was borderline balanced can suddenly feel completely ineffective. Your boiler might be running continuously, consuming gas, but key rooms, especially those furthest from the boiler or with larger heat loss, remain stubbornly cold. This isn't necessarily a new fault, but rather an existing inefficiency that is now being highlighted by the increased demand. Frozen condensate pipes can also stop boilers dead, but that’s a different symptom altogether. Here, we're talking about a system that *is* running, but not delivering comfort.
- Increased heat loss through walls and windows.
- System balancing issues become more pronounced.
- Thermostat in warm room satisfies too early.
- Slower heat-up times for the whole property.
- Risk of burst pipes in unheated or poorly insulated areas.
