When a boiler seems to run for long periods but the house never quite reaches a comfortable temperature, the problem is rarely that the boiler is broken. In most UK homes, this behaviour usually point...
Sometimes a radiator heats exactly as it should, yet the room never feels properly warm. In these cases, the issue isn’t flow, pressure, or air — it’s simply that the radiator doesn’t have enough outp...
If a radiator feels hot while the heating is on but cools down far quicker than the rest once it switches off, it usually means the heat isn’t being held or distributed properly. The radiator is produ...
When a radiator only starts heating properly after the boiler temperature is turned up high, it’s usually a sign that the radiator is struggling to get enough hot water under normal running conditions...
Quick summary: When radiators are hot but the house won’t warm up, the issue is usually heat loss rather than heat production. The system is working, but warmth is escaping faster than it can build. T...
Quick summary: A radiator that never fully cools is usually caused by slow circulation or a valve that isn’t closing completely. It’s often harmless, but persistent warmth can point to inefficiencies ...
Quick summary: A radiator staying cold after draining or refilling the system is usually caused by trapped air or uneven pressure rather than permanent damage. In most cases, it’s a circulation issue ...
Quick summary: When a radiator only heats properly at high thermostat settings, it’s usually linked to flow temperature, system balance, or how the boiler responds to demand rather than a fault with t...
Quick summary: A radiator staying warm after the heating is switched off is often caused by residual heat or slow circulation, but in some cases it points to a valve or system issue. The difference us...
When heating costs rise, the instinct is often to look at bigger solutions like new boilers or higher output systems. In reality, small fixes usually deliver better value, especially in UK homes with ...
