Local considerations
Zone thermostats in Alcester multi-zone systems can fail independently without stopping the boiler or furnace. A zone that reads the setpoint but never opens its valve is a thermostat or valve problem, not an equipment problem.
Zone valve and baseboard issues in older Alcester hydronic systems often get misdiagnosed as boiler faults. If some rooms are warm and others are not, the heat source may be working correctly and the distribution is not.

Alcester HVAC questions
What should I do before the provider arrives?
Set the thermostat to off rather than leaving it calling for heat against a locked-out system, replace a loaded filter, and close off unused rooms. Keep anyone vulnerable in the warmest part of the house.
What if my furnace is still under warranty?
Parts warranties of five to ten years are common, labor warranties are not. Have the model and serial number ready when you call so the provider can check coverage before fitting anything.
My furnace locks out after three tries. What is that?
Three failed ignition attempts followed by a lockout usually means the flame sensor is dirty, the igniter is weak or gas pressure is wrong. After a long idle summer, cleaning resolves it more often than replacing parts does.
Is a cracked heat exchanger repairable?
No. A cracked heat exchanger is a carbon monoxide risk rather than a comfort fault, and the correct response is replacement of the furnace. Any provider suggesting a patch on one is giving you poor advice.
Can I run a space heater meanwhile?
Portable heaters carry their own fire risk and should never be left running unattended or near fabric. Never use a gas range or an outdoor appliance to heat a room, which is a direct carbon monoxide hazard.
