Is it time for a new boiler installation?

If you’re reading this, then your boiler may well have run into trouble. Some issues can be repaired, but others signal that it’s time to replace your boiler.  Even the most reliable boiler won’t last forever, which is why the time for a new boiler installation arrives for everyone at one time or another. Keeping costs to a minimum is a high priority for most, and we can help.

We will take you through all the steps everything you need to know from how to find the most suitable boiler for your home right through to what happens on the day.

What happens on the day of a boiler installation?

Help your engineer make a quick start by clearing the space around the boiler, giving them easy access. If your boiler is installed in the loft, it should be accessible via a set of stairs, a safe walkway and be sufficiently well lit.

A like-for-like boiler replacement is the most straightforward boiler installation and can be completed within one day.

Replacing your existing boiler with a different boiler type is much more complex and can take up to 3 days to complete. This is because new pipework will need to be fitted with tanks or cylinders needing to be installed or removed, depending on the boiler types involved in the replacement.

If you’re planning to have a completely new heating system installed – replacing a combi with a system boiler, for example – then the boiler installation costs will inevitably be higher. Take a look at what’s involved when having a completely new boiler installed:

If a combi boiler hasn't been able to meet your home's demand for hot water then a system boiler would make a suitable replacement. This is because system boilers store hot water in a cylinder rather than delivering it on demand as and when needed.

  • Swap the combi boiler for a system boiler
  • Install the hot water cylinder (a cupboard or loft space are ideal locations)
  • Connect the cylinder to the hot and cold water supplies

Replacing a combi with a system boiler can take 2-3 days. And, in addition to the cost of the boiler and installation, you will also need to factor in the cost of the new cylinder too.

With a system boiler, there are times where you'll need to wait for the cylinder to fill with warm water before you can get hot water from the tap. If you don't want to wait any longer then combi boilers deliver instant hot water on demand.

  • Replace the system boiler with a combi boiler
  • Remove the hot water cylinder
  • Fit new pipework

This can take 2 days and once completed will free up some space around your home.

Conventional boilers and system boilers are similar as they both store hot water in a cylinder. Where they differ is that conventional boilers are open-vent and system boilers are sealed. This means that conventional boilers take their water supply from a tank while system boilers take water from the mains.

  • Swap the conventional boiler with a system boiler
  • Replace the hot water cylinder
  • Remove the tanks in the loft
  • New pipework

The process of replacing a conventional boiler with a system boiler can take 2-3 days and a new cylinder will be needed which will add to the costs.

Replacing a conventional boiler with a combi boiler is one of the more complex boiler installations. This is because they have multiple external parts, while combi boilers don't need any additional tanks or cylinders. Having a conventional boiler replaced with a combi can take 2-3 days as there's plenty of work involved:

  • Swapping out the boiler itself
  • Removal of tanks and the hot water cylinder
  • New pipework has to be fitted as, unlike conventional boilers, combis heat water directly from the mains and deliver it straight to the hot water outlet

Replacing a conventional boiler with a combi would help to save space around the home. However, it's worth remembering that combi boilers are best suited to homes with 1-2 bathrooms (depending on the unit's domestic hot water output rating). So, if you have multiple bathrooms and a higher demand for hot water, a system boiler would be the better option.

Before work begins​

Before work begins​ your Pace Gas Safe engineer will want to check a few things with you first. Such as how many radiators you have, your water pressure, the number of bathrooms in your home and the positioning of the current boiler and flue.

What happens on the day of the installation?

On the day if it’s a straightforward swap — e.g. combi for combi — you should expect the engineer to be done and dusted within the day. It’s worth bearing in mind though, that if it’s a much older boiler system or you’re changing boiler type, there may be complications which prolong the installation. You’ll need to be around to have a run-through of the new boiler controls once it’s fitted.

perform a flush of the heating system

Before the new boiler is fitted the Pace heating engineer will need to perform a flush of the heating system. Over the years, sludge and other debris can build up within the pipes of your heating system and lead to blockages. These blockages will prevent the water from circulating properly, reducing the performance of the system. A chemical flush or powerflush involve chemicals being flushed through the pipe network to clear out the debris.

£ SAVING TIPS

There are signs to look out for that suggest that all is not well in your central heating system.

  • Cold areas on radiators e.g. at the bottom
  • Excessive noise from the boiler or the heating system pump
  • Radiators cold but pipes are hot

After your boiler has been installed...

Once your new boiler has been installed, the heating engineer will take you through how to use the controls. Taking the time to hear about the boiler’s features will help you use your new heating system efficiently. The heating engineer will also provide you with a Building Regulations Compliance certificate which confirms the unit has been installed safely.
 
With the installation complete, it’s time to register the installation with the manufacturer to validate the warranty. Most manufacturers request that this happens within 30 days of installation.

To keep your warranty valid, you will need to have your boiler serviced annually by a Gas Safe registered engineer. The Pace Protection Plan involves our heating engineer inspecting the boiler inside and out, checking the flue pipe, ensuring that the gas pressure is correct and how the boiler performs during operation.

Not only will an annual boiler service keep your warranty valid, but they will also ensure that your boiler is performing safely and to its full potential in terms of efficiency and reliability. Plus, it could bring a potential issue to the attention of our heating engineer before it turns into a fault and you need to pay for a repair.

Annual boiler services ensure that your boiler can heat your home for as many years as possible. And as we mentioned earlier, it’s time to consider a new boiler installation after around 10 years. As boiler technology has developed, the warranty length offered by some manufacturers has extended. In some cases, you can get a warranty of up to 12 years, so you wouldn’t need to consider a boiler replacement until after that warranty has come to an end.
