When thinking about boiler replacement, it is important to recognize that it is a significant investment that will play a role in the energy costs of your property. You need to make the right choice and ensure that you do not create new problems that were non-existent with your previous oil or gas boiler. Keep in mind that selecting the cheap option more often means you may not get the best value for your money in the long run. Beware of installation crews that advise you on shortcuts that could lead to more costs for you later. 
With the following tips, you will be aware of what to do when getting your gas or oil boiler replaced. 

1. Go for a boiler with a reputable brand name.

It is a fact that there are various lesser-known boilers on the market, and they may even have cheaper prices. As a homeowner, you will feel that these can make a notable difference in the final cost of replacement. However, it is important to look at the after-sale services they offer. For instance, if your boiler gets damaged and you need to repair it with specific spare parts, are you going to get them at any source? Should the boiler break down during the replacement, is there a local agent from the manufacturer’s company that can help you resolve those issues?  
These are situations that can happen, and you will need a reputable boiler brand with a reliable network that can offer after-sale services. It ensures that if the problems arise, they can be sorted out quickly without causing major delays in the replacement project. 

2. Confirm that the central heating system in your old boiler is not the issue.

Sometimes, the boiler is not damaged entirely. It could be that your heating system has an incompatible design that can cause technical difficulties with your boiler. Before you replace it entirely, get a heating engineer to check the heater and ensure that it is indeed damaged and needs replacing. Check all parts to ensure compatibility. Inspect the pipe sizing or the heating element. Once you are certain that a replacement is necessary, you should then find a suitable boiler. 

3. Check the location of your boiler.

The location of your boiler plays a part in energy consumption, so you should always pay attention to where it is located. If your boiler is located on an external wall near the source of heat, then you will reduce the amount of water that needs heating. This means you will have lower energy costs compared to a boiler located some distance away from the heat source. If your boiler is away from the house, make sure that the piping is properly insulated to minimize the amount of heat loss. 

4. Make sure your heating system is chemically treated.

Ensure that your boiler heating system has been chemically treated as per the instructions of the boiler manufacturer. Failing to do this could mean that your boiler will suffer some irreversible damage, especially if you live in areas with hard water. If the heating system needs draining as is the case when a new radiator is installed, talk to your installer and make sure that they top up the heating system with the required chemicals after fitting it. You should also ensure annual top-up of the chemicals when the boiler is getting serviced. 

5. Use an authorized and licensed gas installer

Fitting gas appliances and boilers pose certain risks, especially when you are inexperienced. Additionally, sub-standard work on boilers or any appliance is a hazard and can result in serious injuries in case of an accident. You should pick a registered gas installer to install your new boiler to avoid such problems. Ascertain that the installation personnel you hire is licensed and registered as a certified gas installer or ask for recommendations from friends and neighbors.
