Home Heating: What Works, What Breaks, and How to Fix It

If you live in the UK, keeping your house warm isn’t just about flipping a switch. It’s about knowing how your heat pump, boiler or water heater works, spotting trouble early, and fixing simple issues yourself. Below you’ll find straight‑forward tips that cover the most common heating problems we see in Bognor Regis.

Heat Pump Basics & Common Issues

Heat pumps are great because they move heat instead of burning fuel, but they still need care. The two main types – air‑source and ground‑source – have slightly different wear patterns. Most owners notice a drop in warmth when the outdoor unit gets clogged with leaves or dust. A quick clean‑up with a garden hose (turn the power off first) can restore airflow.

Another frequent hiccup is the fan not blowing warm air. It’s often caused by a blocked filter or a loose fan belt. Open the access panel, check the filter, and replace it if it looks grimy. If the belt looks frayed, swapping it out with a new one usually solves the problem. For air‑source units, keep an eye on the outdoor temperature; once it falls below about -5°C the pump’s efficiency can dip, and you might need a supplemental heater.

When a heat pump won’t turn on at all, the culprit is usually the thermostat or the circuit breaker. Reset the breaker, then verify the thermostat is set to ‘heat’ and the temperature is higher than the room. If the unit still stays silent, call a qualified technician – electrical work on a heat pump can be dangerous.

Boiler & Water Heater Care

Boilers are the heart of most UK homes. A noisy boiler often means air in the system or a failing pump. Bleed radiators by opening the valve with a key until water runs out, then close it. If the pump whines, check for debris; a quick flush can clear it.

Cold showers usually point to a water heater problem. First, see if the thermostat is set too low. If the heater isn’t firing, it could be a broken heating element or a sediment‑filled tank. Flushing the tank once a year removes mineral build‑up that reduces efficiency. When flushing, turn off power or gas, drain the tank, and refill slowly to avoid shock.

Resetting a water heater repeatedly often means a faulty thermostat or a stuck limit switch. Look for obvious signs like water leaking around the heater or strange noises. If you can’t locate the issue, it’s safer to let a pro handle the electrical components.

Regular maintenance saves money. Schedule a boiler service every year before the winter rush. During the service, the engineer will check pressure, test safety valves, and clean the heat exchanger. It’s a small cost compared to an emergency breakdown in the middle of a cold night.

Knowing when to DIY and when to call a professional can keep your heating running smoothly and protect your wallet. Simple tasks like cleaning filters, bleeding radiators, or flushing a water heater are safe for most homeowners. Anything involving gas lines, electrical wiring, or internal heat pump parts should be left to a qualified technician.
