Pressure Dropping In The Heating System

Ability provides heating, plumbing and electrical assistance in Kent, East and West Sussex.  As the temperatures start to drop we receive an increased volume of calls from customers saying that the pressure on their boiler has dropped.

Boiler Pressure Gauge

The power to the system must be turned off before starting to re-pressurise the boiler.  It’s something the homeowner can do themselves but if the pressure continues to drop then a heating engineer will be required.  Modern boilers work best usually around 1.5 bar.  The boiler will have a pressure gauge which shows the minimum and maximum operating pressure.

There are 3 main reasons why the pressure could drop.

Bleeding Radiators Low Pressure

When bleeding radiators air is being let out of the system and can cause the pressure to drop.  This can be easily rectified by letting more cold water back into the system.  This is simple to do however each boiler is different so you will need to refer back to the boiler manual or the manufacturer’s website for direction.

Water Leak

If there is a leak in the system the pressure will continue to drop even if you have added more cold water into the system.  It can be very hard to locate a leak but the best place to check first is the radiator valves. Wipe the valves with kitchen roll and place a tray beneath it to collect any dripping water.  If you are unable to locate the leak then an engineer may be needed to locate and fix it because the leak could be behind a bath panel or floorboard.

Boiler Fault

It is important to have your boiler serviced annually as this helps to keep your boiler running efficiently.  Any fault will be detected earlier and can be fixed before further problems develop.  If the pressure in the system keeps dropping after cold water has been added, it could be the expansion valve has failed or limescale could have built up in the boiler.  A certified engineer will be needed to check this out.

Gas Boilers To Be Banned In New Homes By 2025

It has been recommended to the government by the Committee on Climate Change to make a blanket ban on gas boilers being installed in new homes from 2025 to help tackle climate change.  The Chancellor has announced that it will be illegal for gas boilers to be installed into new build homes from 2025. They predict that non-fossil fuel boilers will, of course, be better for the environment but will also be cheaper to run. These drastic measures are being taken because the UK will not meet their targets to reduce greenhouse emissions by 80% by 2050 as anticipated.

It has been recommended that low carbon energy should be used as an alternative to the gas we currently use. The use of methane gas, which releases carbon needs to be phased out and replace with low or zero carbon gas such as biomethane or hydrogen.

What Is The Alternative To Gas Boilers In The Future

It is suggested that green gas compatible boilers should be installed into new homes to enable the transaction from normal gas to green to happen seamlessly. The technology has been tested but further investment needs to be made for green gas to be implemented into our homes. With 90% of our homes using the gas foundation already it is essential that these investments are made. Currently, one-fifth of greenhouse emissions are being created from our homes and a high percentage of that is due to us burning fossil fuels for heating and hot water.

The alternative to using green fuel would be to return to electric heating which is very expensive to run and a step back in our progression to become as energy efficient as possible.

Ability have carried out boiler installations and repairs to gas boilers in the Tunbridge Wells, Sevenoaks, Tonbridge, East Grinstead, Heathfield and Crowborough areas for many years, so if you require any assistance one our friendly engineers will be happy to assist.

Saturday Gas and Oil Boilers with Repairs while the Sun Shines

Saturday Gas and Oil Boilers with Repairs while the Sun Shines

A long day of gas and oil boilers, both installation and repairs today, this Saturday has been punishing and rewarding at the same time. We at Ability have carried out all the gas and oil boiler repairs that were booked in. Therefore we have the satisfaction that all the customers will have working boilers and hot water tanks, toilets flushing, overflows no longer dripping and radiators flowing to all the plumbing needs booked in. Click here to the gas safe site.

Gas and Oil Boilers

Tom has been especially busy, plumbing in Sevenoaks this morning and fitting gas pipework in East Grinstead this afternoon. Terry has completed several boiler servicing calls today in Sevenoaks and as always any small repair work is carried out at the same time.

Central Heating Repairs

Elaine has managed the phones today and we have booked in several quotations for this coming week, things have really started to get busy the last few days in the plumbing and heating world.

The topic today is on soldering and here is a brief description of how it works.

Soldering is defined as “the joining of metals by a fusion of alloys which have relatively low melting points”. In other words, you use a metal that has a low melting point to adhere the surfaces to be soldered together. Consider that soldering is more like gluing with molten metal, unlike welding where the base metals are actually melted and combined. Soldering is also a must-have skill for all sorts of electrical and electronics work. It is also a skill that must be taught correctly and developed with practice.

This tutorial will cover the most common types of soldering required for electronics work. This includes soldering components to printed circuit boards and soldering a spliced wire joint.

Soldering Repairs and Equipment

The Soldering Iron/Gun
The first thing you will need is a soldering iron, which is the heat source used to melt solder. Irons of the 15W to the 30W range is good for most electronics and or printed circuit board work. Anything higher in wattage and you risk damaging either the component or the board. If you intend to solder heavy components and thick wire, then you will want to invest in an iron of higher wattage or one of the large soldering guns. The main difference between an iron and a gun is that an iron is pencil shaped and designed with a pinpoint heat source for precise work, while a gun is in a familiar gun shape with a large high wattage tip heated by flowing electrical current directly through it.

Busy Tuesdays plumbing and heating calls

What a Day at Ability plumbing and heating. We have had a manic day in the office here with more plumbing calls today then any other day in May. Tuesday feels like Monday after the bank hoiliday but we are all back into the swing of things, sorting out everyone’s plumbing needs. So we set off this morning with several boiler services in Tunbridge Wells and Sevenoaks. There are on going installations of gas fires in East Grinstead this week and LPG work in Westerham.

Our Gas Engineers Tom and Max have been working on boiler breakdown repairs today with testing all flues and inlet gas supplies as a priority. We have had new training courses put in place for renewal in gas safety domestic hot water cylinders and pressurised systems. So its all go at Ability plumbing and heating all ready this week. We recommend you test and check your carbon monoxide alarm as we had a customer today who’s batteries needed changing as part of the boiler service. It was fortunate that our Senior engineer in Central Heating tested the alarm for Mrs Smith today and realised that the batteries were flat and so was able to put new batteries in as part of the boiler service at no extra cost to the customer.

Finally we at Ability are looking at new promotions all the time so if you have any ideas about your heating or hot water system that you would like to discuss with us or have any concerns with please do not hesitate to contact us. We will be happy to discuss your requirements and help in any way we can. Our office is open from 8 am to 5 pm for general enquirers and after that we do provide an emergency line for both regular customers and new customers.
