If your house feels like a freezer or your shower runs cold, something in your heating system is off. It could be the boiler, a heat pump, or the water heater. The good news? Many issues show clear symptoms and can be tackled before they turn into expensive repairs.
First, look at the thermostat. Is it set to the right temperature? Does the display work? A dead battery or a loose wire can make the whole system think it’s already warm. Next, listen for unusual noises – banging, rattling, or whistling often means air trapped in the pipes or a failing pump.
Check the pressure gauge on your boiler. Most residential boilers run between 1 and 1.5 bar when cold and around 2 bar when hot. Anything outside that range may need re‑pressurising or a bleed of air. While you’re at it, look for any leaks around the pipe joints – even a tiny drip can cause the pressure to drop.
Boiler won’t fire up: This can be a faulty ignition electrode, low water level, or a blocked condensate pipe. Tilt the boiler gently to see if water pools at the bottom – if it doesn’t, you might need a refill.
Heat pump not cooling: A clogged air filter or a refrigerant leak can stop the unit from delivering warm air. Clean the filter and check the outdoor unit for debris. If the problem persists, the refrigerant might need a professional top‑up.
Hot water running cold: Sediment buildup in the tank reduces heat transfer. Flushing the water heater once a year clears the grime. If the heater is older than 15 years, consider a replacement – efficiency drops dramatically with age.
Radiators are cold at the top: Air trapped in the system creates cold spots. Use a radiator key to bleed the air out. Turn the heating on, wait for it to heat up, then open the valve until water flows evenly.
When any of these fixes feel beyond your comfort zone, it’s smart to call a certified technician. Trying to tinker with gas lines or electrical components without proper training can be dangerous.
