Boiler Replacement Glasgow

When you are looking for a Boiler Replacement or to have a new boiler installation, you need to know what type of boiler to buy. This is often determined by the size of your property, available space, if gas is installed or not, what size of gas pipes you have or if they can be upgraded if needed, if solar panels are fitted etc. And of course, budget plays a massive role in deciding your boiler as well. Balancing up the cost of the boiler and installation versus savings in energy bills and continual cost of repairs to an old boiler have to be weighed up as well.

We work with the major boiler manufacturers to give you the best options for your needs and budget. Worcester-Bosch, Ideal, Vokera, Vaillant, Potterton, Alpha, Baxi and Glow Worm. From our experience, these companies offer the best products with the best warranties and customer service and also have replacement parts more readily available when the warranties eventually run out and parts sometimes need replacing.

Check out our page on Boiler Types for an introduction to the various types of boilers available which will help you to make your decision.

If you are unsure, call 0141-530-1315 for a qualified heating engineer to help you decide which type of boiler is best suited for you.


Replacing Your Boiler Like For Like

When doing a Boiler Replacement, most of our jobs involve swapping a combi boiler out for a new combi boiler. This is by far the most common boiler type and the most common request when we are asked to replace a boiler.

The good thing about this is that most of the time you then know what size of boiler you need, if gas is installed or not, what size of pipes you have etc. All you need to decide on is the make and model of your new boiler which very often comes down to price, brand and length of warranty offered.

We have come across customers who would only have the latest Worcester-Bosch model due to the great name they have and the excellent manufacturers warranty which they provide. This certainly isn’t a bad choice as they are excellent boilers.

Other customers are happy to go with the best price as long as it is a well regarded brand name like Ideal, Vaillant or Potterton and the model still offers a good warranty.

Really, there are no right or wrong answers to this question as long as you are guided along the right path when selecting which boilers to choose from.

Most modern Combi Boilers are all condensing boilers meaning that they re-use the maximum amount of fuel and giving them a 90% rating on the SEB Scale. (See Choosing Your Boiler for more details.)

This means that replacing an old style boiler for a brand new one (whatever the make) will undoubtedly be more efficient therefore saving you money on your energy bills.



Replacing Your Boiler With A Different Boiler Type

Sometimes we will visit a property and there is an extension which has been built or a loft or attic has been converted. The water usage of the household has then changed. For example rather than requiring a 30Kw Combi Boiler, the property may now require a Traditional Boiler to be installed to supply the demand of the expanded household. 

This is when you will have to speak to your boiler engineer about Choosing the Correct Boiler Type and Sizing Your Boiler according to the needs of the property. 



Sizing Your Boiler Replacement Correctly

Occasionally we see that the wrong boiler has been put in the property in the first place. The boiler has maybe been under sized meaning that the boiler is not providing enough heat and flow rate for the household. This leads to reduced water flow and water dropping in temperature when another source is turned on. 

This is most noticeable when you are in the bathroom shower and somebody turns on the hot tap to wash the dishes in the kitchen. If the boiler is under sized, you will notice a drop in pressure and water temperature in the shower as the boiler is then trying to heat 2 water sources when it is not powerful enough to do so. 

The solution is to take advice from your local heating engineer as to the size of the boiler required to efficiently and adequately supply your property. For example, you wouldn’t need a 40Kw boiler to supply a one bedroom flat. This would be over engineering the requirements and paying too much money for a boiler which you don’t need. Similarly, fitting a 25Kw boiler in a 5 bedroom house is not going to supply enough hot water and your boiler is going to be running at full capacity. Either way, you are wasting money.

Therefore sizing your boiler replacement is very important and you should take the advice of your boiler engineer when deciding which boiler to install

What Happens After Your Boiler Replacement

After you have had your Boiler Replaced and you are 100% happy with it. The Heating Engineer has shown you how to operate it, has left you with all the warranty and any additional instructions which may have been left with the boiler installation pack. 

What happens after that…?

Well, the Heating Engineer will firstly have told you that to keep your Manufacturers Warranty valid that you must get your boiler serviced annually. We will therefore keep you informed as to when your Boiler Service will be due for renewal and give you a little reminder nearer the time to get you booked in for that. 

The reason why a boiler service for a new boiler is just as important for an old boiler. Safety is paramount. Obviously, there is a greater chance of having more problems as your boiler gets older. However, we still get calls every week from customefrs who have had their boiler installed incorrectly or even dangerously by other disreputable companies or individuals who are putting peoples lives at risk by performing bad boiler installations. 

Our annual service keeps you and you boiler safe. It also ensures that your boiler is running at optimal performance.

Please remember are always use a Gas Safe Registered Heating Engineer when dealing with any Gas whether it is a Gas Pipe, Gas Meter, Gas Appliance or your Gas Boiler.
