What to Consider When Replacing your Boiler


Getting a New Boiler


Theres a lot to consider when having a new boiler installed, heres a guide to some of the most important points. Not sure what system you currently have? Visit here to check


Old Radiators

Old radiators are rarely a problem as long as they are working well and have a good heat output throughout i.e. no cold spots.

The main problem encountered is when a conventional boiler is replaced with a combi boiler. Due to a combi boiler being pressurised it puts the heating system under much greater duress. If the radiators are corroding internally there is a good chance they can fail when the new system is pressurised.

Shower Pumps

Its important to note a couple of points when replacing a boiler if you have a shower pump.

These are generally installed in the airing cupboard with the cylinder and are quite noisy when running.

If replacing a conventional boiler like for like, your hot water system isn’t touched so your shower and pumped outlets will continue to work as normal.

When converting to a combi boiler the shower pump will require removal. This is because combi boilers work off mains water which cannot be pumped. Often there is no change in the performance of the shower and often it can actually improve it.


Pipes Buried in Concrete Floors

Pipes buried in concrete floors often don’t cause any problems providing they have been protected correctly with a plastic or protective barrier tape.

If this has not been done and you are switching from a conventional to a new combi boiler there is a potential problem.

Due to the existing conventional system being tank fed, if the pipes have a small leak then this will be absorbed into the ground and go unnoticed. When switching to a pressurised boiler the central heating system is topped up manually meaning the pressure will drop frequently and can become a major inconvenience.

Unfortunately there is no way to determine this until the new boiler is fitted but remains an important point to keep in mind.


 

 Room Thermostats

Thermostat

A Room Thermostat controls the air temperature in the room that its in. This is usually the hallway as its a neutral part of the home.The thermostat gives added control to your heating system along with greater efficiency.

We usually install a wireless thermostat with most boilers as there is no disturbance upon installation.

Thermostatic Radiator Valves

Thermostatic Radiator valves allow you to manually control the temperature of individual radiators throughout your home.

This is done by controlling the flow of water through the radiator via the valve. Thermostatic Radiator Valves are recommended when a new boiler is installed, giving both added control and fuel savings.

We can replace individual thermostatic valves whilst installing a new boiler or you can keep your existing valves. Ask us for more information on a quote.

 

 

 


Magnetic Filters

 

 

filterMagnetic Filters offer extra protection for your new boiler. They do this by trapping sludge and magnetite inside instead of letting it pass through the boiler.

They collect all the loose debris harmful the the boiler and are emptied once a year along with your service.

they are a relatively inexpensive way to increase the lifetime of your boiler.

 

 

 

 


Flushing

Chemical Flush

This should always be included in your quote at no extra cost and we will always do this as standard. The cleaner is allowed to run around the system for a couple of hours before your system is fully drained, chemical inhibitor added, and finally filled with nice clean water.

Powerflush

A powerflush will always cost extra as it is a much more in-depth clean of the system. We use magna cleanse equipment (see our portfolio page) which are essentially 2 extra large magnets that trap all the sludge in your system. These magnets are them removed and cleaned, permanently extracting the dirt from your system. A power flush is only recommended if you have a particularly dirty system, the main symptom of which is radiators being cold at the bottom.

We recommend cleaners and inhibitors from the following companies – Fernox , Sentinel and Adey
