Check Your Boiler Before Spending Money On An Engineer

Boilers break down and our heating and water systems can easily pack in. Whether it is weather related or just wear and tear, these things can be very tricky to deal with and be costly to have people come to fix it, if you’re a homeowner. Here are some things to check first before you decide to call an engineer. Of course, you probably do have regular checks on your boiler but ensuring it has all the right parts, wires, pressurisers, Grundfos CR pump, each system has different aspects and yours may differ from a system in a business building or office block. Here’s how you can look into the problem yourself first.

Re-pressurize your boiler

Look for a water pressure indicator on the front of the boiler, if it shows anything below one, then the pressure is surely too low. Next take a look for the boiler’s filling loop, which is probably at the bottom of the boiler or around the lower part and ensure that it is completely switched off and ends of the hose are all well attached to all the valves. Next, open up the valves and you should be able to hear water filling up the system; a trickle or a water sound will indicate; then watch the pressure indicator rise and wait until it is around 1.5 then switch your boiler back on. This can reset certain issues.

Reset the boiler

Look at your boiler’s manual as they will differ from system to system but a general reset can be holding your reset button for around ten seconds and wait until the system kicks back in. this can reset the electrical systems and try it a couple of times if at first it doesn’t seem to work. This can be helpful for minor issues with the signals.

Look at your radiators and bleed the system

Look at the radiators in your home. Check every single one to see if there are any that are not working well. This can help reset your boiler by bleeding the system. Turn off your heating and use a radiator key which can be attached to the side valve and turn anti-clockwise. As it clears you will hear a hissing sound which is the air escape and then once it stops you can close the valve and the air will have been released.

These simple checks will help determine if the problem is small or large. If this fixes the problem, it may be a temperamental system and you may have a small glitch that needs looking at for long term use or it was a temporary glitch that will not occur again but either way you can rule out the issue. If this doesn’t solve the problem, then it is best to seek professional advice but be sure to try this first to save a little bit of money from a call out especially if it is late at night; saving money is key! Check your boilers!
