What is a boiler and how does it heat my home?

A boiler heats water or produces steam and distributes it through radiators, baseboard heaters, or radiant floor tubing for even, quiet heat — unlike a furnace that blows hot air through ducts.

What are the main types of boilers found in Cleveland homes?

Common types include cast-iron boilers (durable, in older homes), high-efficiency condensing boilers (90%+ efficient), combi boilers (heating + on-demand hot water), and steam boilers (in historic neighborhoods).

Why are my radiators lukewarm or cold even when the boiler is running?

This could mean air trapped in the system, sludge/corrosion buildup, a failing circulator pump, or an aging/undersized boiler. Call Stack for professional diagnosis and repair.

What do banging, clanking, or gurgling noises from my boiler mean?

Kettling (banging) = limescale on the heat exchanger; gurgling = air or low pressure; clanking = pump issues. These are serious — call Stack right away.

Why are my heating bills going up but my house still feels cold?

A boiler with scale, leaks, or a failing burner can waste 20–40% more gas. Many Cleveland homeowners see bills jump $75–$200/month — call Stack for an efficiency check.

What should I do if I see leaking or dripping around my boiler?

Shut off the system if safe and call Stack 24/7 immediately. Leaks often come from corroded valves, cracked heat exchangers, or failed seals and can cause major damage fast.

My pilot light is yellow or keeps going out — is that dangerous?

Yes — a yellow/flickering pilot can indicate a carbon monoxide leak, dirty thermocouple, draft, or gas issues. Call Stack’s emergency line right away.

Why does my boiler pressure keep dropping and need frequent topping up?

This usually means a hidden leak in the system (pipes, radiators, or boiler). Call Stack — don’t keep topping up without professional repair.

Why is my hot water running out quickly or not getting hot enough?

If your boiler supplies domestic hot water, a failed diverter valve, plate heat exchanger, or thermostat could be the cause. Call Stack to restore reliable hot water.

How can I keep my boiler running well during Cleveland winters?

Schedule annual professional service with Stack in fall, check pressure regularly, listen for noises, watch for leaks/reduced heat, keep the area clear, and test CO detectors monthly. Always call Stack for any concerns — never attempt repairs yourself.
