Get Multiple Quotes for Your Boiler Installation Project 

Heatable offers a convenient and inexpensive gas boiler installation service, but it’s not your only option. If your boiler replacement project isn’t urgent, you should try to solicit as many quotes as possible before going through with installation. You can reach out to large, national companies, like British Gas and E.ON, or try ringing up local, Bristol-based installers. Both options have their pros and cons, and both can get you a fair deal on the cost of installing a new boiler.

National Installation Companies

Nationwide installation companies are the ones you tend to see advertised in the newspapers and on TV. The likes of British Gas have a network of their own Gas Safe engineers across the country, and some can offer fixed, online quotes. They typically provide reliable, quality service, and have round-the-clock support for any subsequent problems with the equipment.

But these large companies also have high overheads (all those adverts don’t come cheap) and this means they usually pass on these costs to their customers.

Overall, we would expect a quote from a national installation company to be amongst the highest you get.

However, there are occasional discounts and offers available, so it’s definitely worth your time to get an estimate.

Local Heating and Gas Installers

There are lots of small Gas Safe heating engineers around Bristol, and they’ll typically get you a much better deal than their national counterparts.

That said, local installers are in high demand, and you may have to wait a while for service. Keep in mind, too, that these guys won’t quote you right away — you’ll have to schedule an appointment first.

The quality of these firms’ work can also be inconsistent. Some are much better than others and you might not know until they have already begun. Word of mouth is how many of these local installation companies get their business, but make sure you hear good things from at least three or four people before committing to them.

Needless to say, be sure to ask for at least 3 quotes to get a fair idea of what the local market prices are. Better yet, start off by getting an online quote from Heatable, then use it as a yardstick when you compare other installers’ offers.

What Type of New Boiler Do You Need?

First, consider which fuel you’ll use

To begin with, you need to know what type of fuel your boiler uses. There are a number of possibilities here:

  • Gas
  • LPG
  • Oil
  • Electricity
  • Renewable energy sources

What kind of fuel does your boiler use?

In Bristol, most properties will be connected to mains gas. Gas is the cheapest fuel to use and also has the widest variety of cost-effective boilers to choose from, so most people will opt for this.

Consider the Types of Boiler Systems

There are 4 principal boiler types:

  • Combi Boiler
  • Regular Boiler
  • System Boiler
  • Compact Boiler

If you live in a smaller home, and your family doesn’t consume too much water, getting yourself a combi boiler is the most efficient way to go.

These little boilers can easily fit out of sight, and unlike their regular boiler peers, they don’t take up extra space for water storage. Best of all, they supply hot water on demand.

On the other hand, if your home is quite large, and your household uses lots of water, a regular boiler or a system boiler may be the better option.

A boiler’s physical dimensions matter, too — especially if space is at a premium. If you want your new boiler to fit into a kitchen cupboard, consider getting a compact boiler; just note that compact boilers typically cost a bit more that their standard-sized counterparts.

What Size Boiler Do You Need?

Boiler size is not a question of the physical size, but rather the power capacity of your new boiler. It’s something that you need to get right, because if you don’t, you’ll either end up freezing or paying way too much for heating.

Assuming you’re going with a gas-fired combi, these are the 3 most common boiler size ranges:

Boiler Size Radiators Bathrooms Property Type
24kW-27kW 10 or fewer 1 Apartments, 1 & 2 bed houses
28kW-34kW 10-15 2 Medium size 2-4 bed homes
35kW-42kW 15-20 2+ Larger Properties

If you want more definitive advice and don’t fancy calling out a Gas Safe heating engineer, another option is to use Heatable’s online calculator. This online form will ask you various question about your home, such as how many radiators there are and how many bathrooms you have. They will then use this information to give you expert advice on the best boilers for your property.

Boiler Installation in Bristol: How Much Does It Cost?

Assuming that you live in an average-sized Bristol property, use a regular amount of water, and looking for a 24kW combi, you can expect to pay around £2,200 to buy and install your new boiler. If you want to move your new boiler to another location on your property, be prepared to pay at least £350 – £750. That’s because you will need new pipework fitted, a new flue installed with associated works to either your outdoor walls or your roof, and more labour and materials costs.

The numbers above are an educated guess, based on the average market rates in Bristol. If you want a more precise quotation, contact a local installer, national company, or fill out Heatable’s quick survey and get your guaranteed quote now.

What Extras Will You Need?

In this section, we will outline three extras which we would generally recommend most Bristolians invest in when they get a new boiler. They are likely to extend the life of your boiler and ultimately save you money:

Remove Sludge From Your System With a Magnetic Filter  

A magnetic filter is a component that fits in your boiler and collects up any metallic debris that is floating around in your heating system. This debris can become sludge and clog up your boiler, affecting performance or even damaging components. This filter helps to prevent that.

Protect Your New Boiler From Limescale Build-up Scale Filter 

Bristol is a hard water area so limescale is likely to be a big problem in your boiler. A scale filters helps to prevent limescale buildup which can damage components and prevent your boiler from working properly. It reduces repair bills, extends the life of your boiler, and is essential in Bristol.

Clean the System With a Hot or Power Flush Before Fitting the New Boiler

If you have an older central heating system, it is likely that some sludge and limescale has already built-up. To stop this getting into your new boiler, most installers will recommend you have a hot flush or a power flush to clean it out. This is worth doing but just be aware that power flushes can damage some older heating systems, so make sure your system can cope with one before letting your Gas Safe engineer push ahead.

If your installer recommends other possible extras, do a bit of research to see what they are and whether they are worthwhile before agreeing.
