1. Turn off the power
Simple, but essential: before handling any heating appliance, we cut the water and electricity supply. A gesture that avoids both electrocuting and flooding the house.
2. Check for leaks on the radiators
The tightness of the radiators decreases over time and ultimately, small leaks may appear. The thing ? With a minimum of knowledge, you can replace worn seals with new ones yourself to restore tightness of radiators and find an optimal functioning of the heating!
3. Bleed the radiators
In principle, the radiators should be purged once a year to remove the air that is trapped there and can cause noise or malfunction. So we think about it in case of problem with the heating system ! A steam trap exists on most radiators, just turn it ... and provide a container to collect the water flowing.
4. Clear the radiators
If the water coming out of the radiator at the time of the purge is brown, this means that mud has accumulated over time in the heating system. So we go to step sludging consisting in injecting liquid to evacuate the sludge, a maintenance which should in theory be carried out every 5 years approximately. And kings or queens of plumbing except · e · s, we turn to a specialist to avoid flooding.
5. Check the boiler pressure
On a standard boiler, the pressure must be between 1 and 2 bars. If ours shows a level too low, we simply open the filling valve located below to reach a normal pressure level. Please note that restoring good pressure is generally essential after bleeding the radiators!
6. Check the cable gland nut
The cable gland nut is this metal nut located between the tap and the radiator, whether manual or thermostatically controlled. Over time, the nut can loosen: in this case, remove the valve head and then tighten the nut with an adjustable wrench.
7. Check the thermostat
When a radiator stays cold, it is sometimes that the thermostat was simply deregulated ... Before calling the plumber, we therefore think of checking the position of the tap on the thermostatic radiators, just for the principle!
8. Check the power supply
The Electric heating make his own? We start by checking the circuit breaker: if it has blown and it jumps again after having reset it, it is a leak or a short circuit. If the current arrives normally at the heating system, it is checked that the power cables are well connected. And if nothing changes, we call a pro.
9. Know when to stop!
Repairing yourself is good, calling a professional before causing damage is better. If the heating failure lasts or must be touched plumbing and electrical, no question of playing, we make an appointment.
10. Know who to call
Plumber, heating engineer, electrician ? In principle, the plumber works on hydraulic central heating installations such as water radiators or water heaters. The heating engineer takes care of gas, oil or electric boilers. The electrician takes care of the general electrical installation, for example if the outlet no longer works.
