Central Heating FAQ’s

We do things a little differently with our boiler installations. It has become the fad to try and sell boilers online, have customer pay upfront and then sub-contract the work out to heating engineers who have often never met anyone from the company doing the selling. Every boiler CGH Heating sells, will have a pre-installation appointment organised with our team, letting you ask any questions you have about the quote/work before going ahead. It also gives us a chance to tell you a bit about who we are and why you should choose CGH Heating for your installation.

Our process works like this:

Pre-installation safety survey
We will visit your property, look at the work and answer any questions you have about the work.

Fixed price quote
We will provide a fixed price quote, ensuring there are no nasty additional costs when we arrive to do your installation. Our fixed price quotes will recommend different options of boiler models for you to read through and pick what is best for you, depending on price, efficiency and performance.

Work to your schedule
Although we do get very busy, we will always try and accommodate your needs based around working hours or holidays or your timings

One of our Gas Safe Registered heating engineers will install your new boiler, along with taking your old boiler and system away for scrappage. 90% of our installations take between 6 – 8 hours.

When you decide to go ahead with your installation, we take a 10% deposit and you can pay the balance via a number of ways including cash, cheque or one of our payment plans.

  • A-rated, award-winning boiler
  • Safe removal & disposal of your existing boiler and old materials
  • A pre-install cleanse of your central heating system
  • Chemical Protection included post installation
  • Installed by an expert Gas Safe registered CGH Heating engineer
  • Delivery, parts and all safety attachments

Yes, we currently offer plans with terms ranging from 0% finance or 3 to 10 years with a fixed rate of 8.6% APR.

Step 1
Our team will call you to discuss your installation and get some suitable dates from you for when the work can be done.

Step 2
Our Gas Safe heating engineer will arrive, bringing with him all the appropriate materials and parts required to complete the work.

Step 3
Our engineer will perform a pre-install heating system flush, remove your old boiler (or heating system), install your new boiler (or heating system), and make sure the new installation is running safe and efficiently.

It always helps to have a clear space to work from. Moving items away from our work area will help greatly speed up our boiler installation time.

To keep the boiler within warranty you will require a yearly boiler service. We currently charge £79 (inc VAT) for this service with an annual reminder of when you need this done.

We are open 7 days a week, so email us on info@cghpropertyservices.co.uk or call on 0141 4655355 with any question you may have.

If you decide to go ahead and install a new boiler in the place of an old energy inefficient one, you should expect to save some money on your gas bills. The boiler installation costs or boiler replacement costs are more than likely to be significantly outweighed by the savings you are in line to make in the future.

If you want to increase the pressure in your shower, use a spray with fewer/smaller holes. If you want to increase the flow, you should buy a bigger boiler, or turn the water temperature down on the boiler. Your combi boiler is about three times better than the best electric shower you can buy.

Through the Governments ECO scheme, private tenants and home owners who receive the correct combination of income related benefits can qualify to have their old boiler replaced free of charge, or have the cost subsidised.

To replace your old, broken or in-efficient boiler you could cost as high as £4000. However, thanks to the ECO scheme, those who are in receipt of Pension Credit (which is not to be confused with a standard state pension) could possibly claim a grant to have theirs replaced free of charge, or subsidised.

Because boiler breakdown is very common due to poor attention being paid to maintenance, and are expensive to fix, most insurers exclude it as standard from home insurance policies. In most cases, you have to purchase emergency home cover as an add on to your insurance policy.

If you don’t use a Gas Safe registered engineer and attempt installing the boiler on your own, you still need a certified and competent professional to test, accept, and sign it. But, a reliable engineer will likely be hesitant to commission a boiler that they have not personally fitted themselves.

If your new boiler is installed by a Gas Safe Register/CORGI-registered or OFTEC-registered installer, then you will get a building regulations compliance certificate from Gas Safe Register/CORGI or OFTEC after all the work has been completed.

Free, and very heavily subsidised replacement boilers are available via ECO, a Government Scheme which has been created to help low income households access various home efficiency improvements to reduce the overall cost of heating their homes.

Firstly, you should ensure that your boiler is serviced every year. An yearly service is regular enough to keep your boiler in good working condition.

These are the benefits that qualify automatically. ECO grants are funded by the UK’s biggest energy companies to give low income people access to replacement boilers. Households in receipt of Pension Credit and Child Tax Credit automatically qualify for a free boiler.

Could Your Tenant Get a Free Boiler? If you’re the landlord of a property and your tenant is in receipt of all the correct combination of income-related benefits, then they could qualify for your old boiler to be replaced through a government grant.

Underfloor heating water systems are made to be used with heat pumps because they only require a low water temperature. The best boiler to use is a condensing boiler as they are highly efficient. A condensing boiler works by using the latent heat created using another heat exchanger fitted inside.

Almost all UK domestic central heating systems use 28 sec oil, which is sometimes known as kerosene. This fuel burns more cleanly than heavier oil products such as gas oil, which is also known as 35 sec heating oil.

For a medium to large 3-4 bedroom house with up to 15 average size radiators, 1 bathroom and an en-suite bathroom, a 28-34kw Combi-Boiler would be installed. A 35kw and a 42kw Combi-boiler would be for a large house with anything up to 20 average size radiators and 2 bathrooms.

It is a thermostat that Wirelessly connects to a receiver which allows you to control your heating and water temperature at home. Hive Hub Connects your Hive products so you can control them remotely with their app wherever you are. Just plug into your broadband router, and you will be up and running.

A power flush is a cleansing process which gets rid of sludge that has built up inside your central heating system. If this sludge is left in your system, it could have an impact on the efficiency of your heating system by restricting even distribution of heat around your home.

A power flush could be a solution to clean and maintain your central heating system. Eventually, the sludge in your system could also cause severe blockages and damage, leading to a costly breakdown to repair. During a power flush, water is sent rapidly through the system to remove debris and sludge.

An agent must arrange maintenance by a Gas Safe registered heating engineer for all pipework, appliances and flues, which the landlord owns and provides for their tenants use. They must also arrange an annual gas safety check to be carried out every 12 months by a Gas Safe registered engineer.

If you need to install a new boiler, it’s now recommended to also upgrade the radiators if they were installed before 2000. Heating installers will now likely recommend to the homeowner that it is worth the extra investment of a full set of radiators if a new combi-boiler is being installed.

Central heating means any home heating system powered by a single heating source. Most commonly a system of pipes and radiators powered by a gas or oil burning boiler. Electric central heating is the same as a conventional central heating system but with an electric boiler.

A central heating inhibitor can help to prolong the life of your central heating system by protecting your heating system against the sludge build-up, scale and corrosion. An inhibitor for heating works by preventing metal from rusting, by adding a protective coating.

Your combi-boiler can be losing pressure for a number of reasons. Pressure loss could be caused from a leak in the pressure relief valve itself, a problem in the expansion vessel, air in your system, or a leak in your heating pipework itself.

Some radiators can occasionally get a fair bit warmer than others. When this happens it usually means that your central heating system is out of balance. In some cases though the radiators can be different temperatures due to the distance that water that heats them has to travel from the boiler or pump.

A combi-boiler is both a high efficiency water heater and a central heating boiler, combined within one compact unit. So, no separate hot water cylinder is required, offering space saving within your home.

A central heating filling loop is a pipe that connects a central heating system to the mains water supply. It is used to re-pressurise your central heating system with water. The filling loop is not part of the boiler but does connect, and therefore is close, to the boiler.
