How to choose the right boiler installation expert

Finding the right plumbing and heating engineer to replace your boiler system

The decision to buy a new boiler is commonly made in haste. Mostly, you want to get your central heating back to its normal working condition and get hot water flowing as fast as possible after your boiler stops working in the middle of the cold winter season. However, the process of choosing a new boiler and installer can be quite challenging. More importantly, you might end up paying an arm and a leg if you choose an unreliable boiler or installer.   

 

To help you understand the proper process of choosing the right boiler and installer, we have compiled a comprehensive step-by-step guide from experts in the industry. Tips on how to extend the life of your boiler are also included in this list. To learn what you need to find out from your boiler technician (from what to look for in a trustworthy boiler installation engineer to how to inspect a quote to ensure that it represents value for your money) when they come in for an in-person visit and give you a cost estimate, read on below. Read our detailed boiler guide to learn more about the best option, suited to your specific needs.    

 

Boiler Installation Cost  

 

Your boiler engineer should take their time when putting together a cost estimate for the installation of your new boiler. Before recommending a suitable boiler type and size, the right installer should carefully assess your home’s hot water and heating needs by conducting a comprehensive survey. As such, before talking with an installer, be sure to consider the following factors.   

 

For The Best Outcome Answer The Following Questions 

 

In addition to informing your installer about any plans, you might have for your home in the future, make sure that you layout your hot water requirements comprehensively. Take some time to ponder the following questions and use the answers to brief the boiler installer: 

 

  • How many outlets do you normally draw hot water from regularly?

 

This question tries to ascertain how hot water is used in your household on a regular basis. 

 

  • Would you like to have a shower that requires pumped power in the near future, or are you already using one? 

 

A powerful electric pump cannot be paired with a combi-boiler – which means that you cannot enjoy the boiler’s space-saving benefits. As such, you will be forced to sacrifice your shower’s pump if you choose to go with a combi-boiler.  

 

  • Do you normally experience any fluctuation in your home’s hot water needs throughout the year?

 

If you normally have guests staying over during the holidays, or any other time in the year, your hot water needs are likely to fluctuate. 

 

  • Are you planning to conduct any related home remodeling projects in the near future? 

 

It is important to inform the installer of any future plans to install under-floor heating, extra bathroom, extension, solar panels, or loft conversion. 

 

  • Has the heating system in your home been experiencing any issues? 

 

Inform the boiler technician about any, and all, of the problems that your existing heating system has been experiencing.  

 

  • Do you have a preferred brand of boilers in mind? 

 

The best boilers are most likely bound to be three times more reliable than the worst ones in the first 6 years, as reliability is quite varied among different brands. Regardless of what your installer says, you should only choose from our recommended list of highly-rated brands. Always remember to choose a brand that suits your needs, instead of what the installer says, especially because some installers are paid (or rewarded) to recommend some brands.     

 

Unlike the best ones, the worst brands are 3 times more likely to experience problems. 

 

To ensure that the installer can recommend a boiler that is suitable to your home, it is paramount that you comprehensively answer the above questions.  

 

For the best installation, don’t forget to ask about the following. 

 

A good installer should be able to point out the following about your hot water requirements to ensure that you make an informed final decision. Be sure to ask about the following if the installer fails to mention any or all of them. The right installer should be able to explain all of the following extras, pointing out which is necessary.    

 

In most cases, some of the extras mentioned below will not be required. The benefit of getting each service should be compared to the cost – which varies from property to property.   

 

Condensate Disposal 

 

The condensate – water produced from the boiler – is directed to the drain through a network of pipes. The need for external piping should be minimized. The installation expert must ensure that any external piping, if necessary, is installed per instructions from the manufacturer, and shielded from cold weather.  

 

Boiler Water Treatment 

Assuming that you live in a 3-bed semi-detached home with ten radiators, you can expect to pay around 375 pounds for water treatment – i.e. flushing and cleansing. A straightforward gravity cleanse and flush – with a chemical inhibitor at the system’s final fill – is the minimum requirement for most heating systems. On the other hand, a power-flush might be necessary for systems that have a lot of sludge. The best fit, as well as the reasons behind that choice, should be pointed about by your installer. Here are some of the signs of a system that has a lot of sludge:    

 

The heating system is noisy during operation

 

The system takes longer to heat-up

 

The radiator has cold spots 

 

Using a tissue to carefully draw a small volume of water from the radiator valve, you can get an idea of just how dirty or clean it is on your own. To prevent the accumulation of scale, corrosion and sludge, remember to ask the installer to add a chemical inhibitor when refilling your heating system.  

 

Scale Reducers/System Filters

 

Since scale reducers and system filters can extend the life of a boiler, find out from the installer if they are necessary for your new system. The cost of buying and installing them should be about 120 pounds. Combi-boilers installed in an area with hard water normally require scale reducers. Before the process of installing a new boiler starts, you must consider the need for a system filter or the previously described powerflush, even they may not be necessary for all situations. Sooner or later, you are bound to encounter various reliability issues if your new boiler is installed on an incompatible or dirty heating system.
