What To Do If Your Boiler Loses Pressure ?
 

Boiler loses pressure ? Your combi boiler can be losing pressure for a number of reasons but the good news is that low pressure is relatively easy to diagnose and, in some cases, you can put it right yourself. Listed Below are a number of reasons to why your boiler has low pressure and how to fix it.

 

What is boiler water pressure ?

Your boiler will heat cold water that flows around the pipes and radiators throughout your home. The water pressure in your home needs to be stable for it to work efficiently. Water pressure in most modern combination boilers is maintained by a ‘filling loop’, which connects to your cold water pipe.

 

What Causes Low Boiler Pressure ?

There are two main causes for low boiler pressure, which are:

  1. Water Leaks : A leak from your pipes, boiler or radiators can often be hard to spot but take a look around your home for any damp patches and water. You should never attempt to look for leaks inside your boiler though, always contact a RGI Registered engineer.
  2. Bleeding Radiators : When you bleed a radiator you’re releasing air and with it lowering the pressure in your system, which can create a drop in water pressure as a result.

These are not the only reasons your boiler pressure might be low so if you can’t find a leak and you haven’t been bleeding your radiators recently then consult a qualified engineer.
 

Is Your Boiler Losing Pressure But There is No Leaks?

Whether you have an oil or gas, system or combi boiler, pressure loss is usually directly related to a leak. 99% of the time, a boiler losing pressure is a leak. Unless the dial sits at 0 even when topped up there’s a leak somewhere, even if you can’t see it.

 

Boiler Losing Pressure But There is No Leaks ?

Pressure Relief Valve is Faulty : Boilers will normally operate at 1.0 bar – 1.5 bar but they can reach 3 bar if there is a problem. A pressure release valve notices this abnormal change in system pressure and releases it. If the PRV has failed, it will cause the boiler to lose pressure.

 

Auto Air Vent Leaks : Central heating systems can collect air pockets over time. Bleeding the radiators is the best solution, but the auto air vent which is normally inside the boiler casing on newer combi boilers can also help to combat this problem but if the auto air vent is faulty, it could be losing pressure.

 

Leaking Radiators, Towel Rails and Radiator Valves are Leaking : The smallest of leaks with radiators can cause your system to lose pressure. This is the most common cause low boiler pressure. Check all your radiators, radiator valves and towel rails and see if there is any sign of water leaking. A small weep on a radiator valve is enough to cause low pressure on your boiler. If any of the connections are very loose, carefully tightened them up, this will usually solve the issue.

 

Radiators Are Full of Air : If you’ve recently had work carried out to your central heating system, it may have collected some air in the radiators and towel rails. You can release this pressure by using a bleed key. To bleed radiators and towel rails, simply open the vent with the key slightly. You’ll start to here air hissing out, once the air stops water will start to drop out, now close the vent off. Do this to every single radiator and towel rail in the property. Remember if you are constantly removing air from the radiators the pressure will drop each time you bleed the radiators.

 

Expansion Vessel : A faulty expansion vessel can cause pressure loss in a boiler. If re-pressurising the expansion vessel doesn’t work, the vessel will need to be replaced to stop the boiler losing pressure.

 

Pressure Gauge is Faulty : There is a chance the pressure gauge on the front of the boiler is not reading correctly, it is unlikely but it has happened. This is quite dangerous, especially if you are constantly topping up the pressure. Turn off the boiler and contact a RGI Registered engineer straight away.

 

How can I check my boiler pressure ?

Normally on the front of the boiler you will find a water pressure gauge, it will either be a needle gauge or a digital gauge which will indicate high and low pressure warnings.

Boiler Pressure Gauge

Explanation Pressure Bar Setting
0.5 Bar : If pressure is below 0.5 bar, water has been lost from the system and must be replaced. 0.5 Bar Boiler Pressure
1.0 Bar : When the radiators are cold this is normal pressure. 1 Bar Boiler Pressure
1.5 – 2.0 Bar : When the radiators are hot this is normal pressure. 2 Bar Boiler Pressure
2.7 or above Bar : If the pressure gauge on your boiler indicates high pressure (above 2.75 bar), then you may need to bleed a radiator to bring the level down to around 1.5 bar. 3 Bar Boiler Pressure

 

How To Fix Low Boiler Pressure Myself ?

There is many brands and types of boilers, so the boiler pressure systems will differ. The first thing to do is to check the boiler manual and see if you can re-pressurise the system yourself. Your boiler may have instructions on the rear of the control panel. Please note that if you need tools to remove the panel on a gas boiler, don’t touch it. Call a RGI Registered Engineer to do this.

 

How to Re-pressurise Your Boiler Heating System

  1. Turn the boiler off and give it time to cool down.
  2. Locate the filling loop – this is usually a metal hose with 2 valves attached at each end.
  3. Attach the filling loop to your system, if it’s not already, ensuring it’s tight and secure.
  4. Open the valves on your filling loop (or valve if there’s just 1) to allow water from the mains into the heating system – you should be able to hear the water flowing into your boiler at this point.
  5. Keep an eye on the pressure gauge, filling it until it reaches the 1.5 mark is usually ideal and be careful not to over-pressurise the system.
  6. Now turn the valves back to their original position to stop the flow of water.
  7. You should then release the filling loop and expect some water to come out of the loop. If water is continuously flowing, tighten the valves.
  8. Switch the boiler back on and if needed, press the reset button.

 

Do I need to call a RGI Registered engineer ?

After following these steps, you should be left with a re-pressurised boiler but If you are in any doubt about how to re-pressurise your boiler system, or you have already done so according to the user manual but are continuing to have pressure problems, please contact our expert RGI Registered engineers and we will diagnose and fix the problem.

Five Signs a Boiler Service is Needed for Your Boiler

Five Signs a Boiler Service is Needed for Your Boiler

Boiler Service

 

A boiler service is very important, a well-maintained boiler can last up to 15 years and while an annual boiler service will help to ensure the best possible lifespan of your central heating system, the older your boiler gets the harder it will be working to heat your home.

 

A boiler in need of replacement is unlikely to be energy efficient or cost effective, but more importantly, it could be a danger to you and your family.

 

Serious boiler problems can lead to more than a lack of heat. A serious concern is carbon monoxide poisoning that can be fatal if it goes unnoticed. If any of these signs are manifesting themselves, have a registered RGII technician (Gas Boilers) or a registered OFTEC technician (Oil Boilers) out to have a look at your boiler.

 

1. It has not been serviced in a year

Regular servicing is very important. So if you have not serviced the boiler in more than a year, don’t wait for the serious signs to consider getting it serviced. Your boiler is subject to wear and tear and regular maintenance is necessary to ensure your heating system is efficient.

 

2. The Pilot Light keeps Going Out

A pilot light that will not stay lit is a sign that it is not functioning properly. The pilot light is the ignition source for the boiler; if it does not stay lit then the burners for the boiler cannot be turned on.
Also if the pilot light burns a yellow flame, this could be a sign of carbon monoxide and you should call a registered technician straight away.

 

3. Your Boiler is Making Strange Loud Noises

If your boiler is making an unusual noise, it won’t take long to spot it. Your boiler heating up is one of those sounds that will fade into the background; that is until something is not working properly.
There could be a number of faults that are the cause of any strange or loud noises that are not typical with the boiler, this will be often due to wear and tear of the pump and fan.
It is important to have it checked at the earliest opportunity by a registered technician.

 

4. There is a Strange Smell From Your Boiler

One of the signs that your boiler needs a service is that a strange smell coming from it. This happens when there is a gas or oil leak in your boiler. Leaks can lead to carbon monoxide poisoning if unchecked.
If you notice dark marks on the boiler casing, you should contact a registered technician immediately.

 

5. Your Home Doesn’t Feel as Warm as it Should

If your home feels cold even with the heating switched on, then the boiler could be at fault. It is important that an accredited plumber or RGII registered technician (Gas Boilers) investigates the reason why your home is not heating up as it should be. Assuming that all of your radiators are in good working order in which case a power flush might be needed on the heating system but if the radiators are working then the boiler will need to be checked.

 

An annual boiler service is important to keep your boiler well-maintained and to ensure the best possible lifespan of the boiler.

Tips on how to Reduce Your Home Energy Bills and Save Money

Reduce Your Home Energy Bills

 

Home Energy Bills

 

If you are concerned like all families are worried about your energy bills getting out of hand these are few helpful yet simple tips to keep on top of them.

 

Use a comparison website to check gas and electricity rates

If you are not 100% sure you are getting the best rates for your electricity, gas or oil energy bills. Then we recommend you using a comparison website to find the best deal out there for you and your family. There are so many introductory offers available from all the main suppliers and if you bring your electricity and gas to the one supplier you can get even better rates. There’s no need to worry about switching to a new tariff or supplier, it’s all very straightforward. But remember to read the small print.

 

Pay your bills online

Homeowners and business can avail of serious savings on their energy and utility bills, simply by changing the way they pay. If you agree to pay online and by direct debit you will receive even greater savings. Try to have paperless billing also there are even greater savings here. If you have access to the Internet, make sure you use it, let your fingers do the walking.

 

Remember to read your meter regularly

Homeowner end up paying much more than they need to for their energy bills, as they go on the estimates given to them by their suppliers. If you check your bill at the reading if it has a € beside it will mean Estimate. If it has an (A) it will be an actual reading, we recommend reading your meter regularly, so your bills will be based on accurate readings. You should be checking your meter at least once every three months and informing your supplier or updating your online account. If you’ve been overpaying and have a lot of credit on your account, you can ask your supplier to give you some money back.

 

Only heat your home when necessary

If you’re going out for the day, then you won’t really need your central heating or hot water on, as no one will be there to benefit from it. We recommend investing in a timer so that your heating only comes on when you need it to. Make sure you also turn down the radiators in any rooms that you are not using and keep all windows and doors shut when the heating is on. In really cold weather we advise to close the curtains around 6pm when it is starting to get dark as it will save any heat already in the house.

 

Draught proof your home

One of the easiest ways to make energy savings is to draught proof your home. SEAI (sustainable energy authority of Ireland) say by simply investing in some cheap materials to seal your windows, doors, loft hatches and pipework. Whilst you’re at it, we recommend sealing your letterbox, as this is one of the main culprits for letting out heat in the autumn and winter. It’s also an area that people often forget to draught proof!

 

Put on some extra layers

Homeowners use far much more energy than they need to, simply because they insist on walking around in a t-shirt in the middle of winter! “Wake up it’s not the Caribbean” By simply putting on a cardigan or jumper, you will find that you can lower the temperature of your home a number of degrees and can reduce around 10% to 20% of your heating bill. That can make a huge difference in the long run. It may even help you save that extra money to get you to the Caribbean.

 

Upgrade your boiler

Swapping your old boiler for a new condensing a rated boiler will dramatically cut your energy bills by a minimum of a 1/3 each year. Make sure you get quotes for a new boiler installation, so you secure a competitive price. We would be delighted at Dewar Gas & Oil Service to offer you a great deal. Our professional in-house staff will be on hand to provide you with a no obligation quote.
