Quotes for condensing boiler installation, repair and replacement
Perhaps the old boiler sounds like it is on its last leg and it is time to replace it with a new condensing boiler. It is important to know the latest regulations in the UK regarding boiler replacement and to have a Gas Safe registered engineer do all the work. We are able to supply you with free quotes from skilled boiler services that comply with all regulations and employ registered professionals to do the work.
Condensing boilers are the versions most people are choosing when replacing their old boilers. Conventional boilers lose about 25% of their efficiency by emitting gases into the air through the flue. In contrast, condensing boilers utilize an extra-large heat exchanger to recover a significant portion of the wasted heat and recycle it for use in heating a home or building. This saves on both energy costs and carbon dioxide emissions.
There are reasons why the UK government mandates the replacement of old boiler systems with condensing boilers, and it all comes down to the way in which they work. While a conventional boiler has one heat exchanger, which can create inefficiencies, a condensing boiler contains two. Water that has been cooled as it travels throughout the system enters the secondary exchanger first, where it picks up heat from the combustion gases present in the flue. The moisture in those gases condenses (hence the name of the boiler system) as it cools, and it forms droplets near the very bottom of the exchanger. Those droplets drain out and enter the primary exchanger where it collects even more heat before being pushed through to your home’s water tanks and radiators.
While it may seem as if a condensing boiler would use more electricity due to the dual heat exchanger technology, this is not the case. The secondary heat exchanger makes use of the heat already present in your system’s flue, which costs you nothing extra, but finds its way into your water rather than the atmosphere. That’s precisely why the UK government mandates the installation of condensing boilers; the energy savings and reduction in carbon footprint is truly sensational.
A qualified condensing boilers professional may offer advice on the best type of boiler to suit the particular needs of a home or office. The basic condensing boiler types include the back boiler which combines a fireplace with the boiler; a combi boiler which provides hot water on demand; a regular boiler which has separate controls, cistern and hot water tank and a system boiler which is smaller and saves space.

When replacing older boilers with condensing boilers, you will be able to enjoy a few benefits. These include:
With few exceptions, UK regulations require that condensing boilers be used when replacing old boilers in homes and other buildings. Costs for these newer boilers may vary depending on size, type and other extra features; however, savings on energy costs will begin immediately after installation due to the higher efficiency of this type of boiler.
Switching from traditional boilers to condensing boilers will not only save on energy costs, but will also decrease the amount of carbon dioxide emitted into the atmosphere by as much as 1.7 tons per boiler each year. According to the Energy Saving Trust, boilers in the UK account for approximately 60% of carbon dioxide emissions. This makes condensing boilers environmentally responsible choices for most heating needs.
Traditional boilers are only around 75% efficient meaning that about 25% of their energy is wasted. Condensing boilers are at least 90% or better in terms of energy efficiency; therefore, the UK has issued 2 mandates concerning boiler replacements in most cases. All gas-fired boilers replaced after April 1, 2005 must be condensing boilers and all oil-fired boilers replaced after April 1, 2007 must be condensing boilers.
When looking for experts on condensing boilers, our service can help you locate qualified Gas Safe registered engineers in your area. In addition, there are several other options to consider when installing a condensing boiler including adding a time programmer to control the room temperature automatically and a cylinder thermostat to make the function of a hot water tank more efficient and further reduce carbon dioxide emissions.
Proper maintenance of condensing boilers helps prevent unnecessary break-downs and expensive repairs. One of the biggest problems to avoid that could result in a costly repair is the freezing of pipes, and the most efficient way to prevent freezing is to leave the heating on low constantly. In the event that a pipe does freeze, the best way to thaw it is to place a hot water bottle on the pipe or pour warm water over it and reset the thermostat to low heat.
Each year, several homeowners are seriously injured as a result of trying to cut costs and install their own boiler units instead of hiring a qualified professional. However, what many of them fail to realise is that in the event of becoming injured or causing damage to their properties, most homeowner’s insurance policies will not pay out. Another point of concern is that boiler manufacturers will not honour a warranty on their units if a qualified and certified technician has not installed them.

Condensing boilers are energy-efficient models that use waste heat to heat hot water with.
They are energy efficient, economical to operate and maintain, and will last for a number of years without having mechanical problems.
Condensing boilers are an energy efficient alternative to the standard boiler models. On average, and this does not include installation, parts, or labour, a condensing boiler will cost from £800-£2,500.
The primary disadvantage of using a condensing boiler, especially the stainless steel varieties, is that they can be easily damaged and if damaged, they have to be replaced in their entirely because they can be difficult or impossible to repair.
This may be possible if your chimney is outfitted with a stainless steel liner, provided your local building codes do not prohibit it. Find out more by speaking with a professional installation technician from our extended network.
Yes. These units have been designed in such a way that they work far more efficiently than their older counterparts ever could. This allows you to save hundreds of pounds per year in energy bills.
The global effort to reduce carbon emissions has led to laws and mandates in the UK requiring homeowners to install energy-efficient appliances wherever possible – particularly when it comes to heating and cooling. Because boilers make up some 60% of the carbon emissions coming from the UK, the government now requires the use of condensing boilers, which reduce that number substantially.
Performing a boiler installation in a DIY capacity is not recommended because it could result in you injuring yourself or even causing a substantial amount of damage to your property if it has not been installed correctly and malfunctions. Most homeowner’s insurance policies will also not pay out for losses or damages if these units have not been professionally installed.
All boiler units require regular maintenance to ensure that they are operating as efficiently as possible. Most boiler manufacturers recommend that their units be serviced at least once a year and that a professional be contacted at the first sign of a malfunction.
