The hustle of city living can be tough sometimes. If you live in the city, picking the right boiler to keep your home in London warm and cosy is very important. The Baxi 830 combi boiler might just be the contender you need.

Below, we break down the key features, the benefits, and how it stands against the competition to help you evaluate whether the Baxi 830 suits your home.

Why You Need To Pick A Baxi Boiler?


Baxi makes various types of boilers like combi, regular, and system boilers. They're known as a mid-range brand and are a good choice for those on a budget. Plus, getting parts and support is easy since they're made in the UK.

What Is a Combi Boiler?

Combi boilers are short for combination boilers. These boilers can supply hot water and central heating in the same system. However, combi boilers are the preferred choice for gas central heating and hot water in the UK. They are high-efficiency water heaters and central heating units, saving space by doing away with the need for a hot water cylinder.

How Big Is The Baxi 830 Boiler?

The Baxi 830 measures H 700mm x W 390mm x D 285mm. It's designed to be wall-mounted and can fit inside a kitchen cupboard, keeping it hidden. Plus, it's lightweight at just 29.5 kg, so it's easy for installers to move and set up.

How Do Baxi 830 Combi Boilers Work?


Baxi 830 combi boilers work differently from system or regular boilers. Instead of needing a hot water cylinder or cold water storage tank, they get water directly from the main supply. This makes them efficient because they only heat water when you use a tap or turn on your central heating. Plus, they're space-saving since everything the boiler needs is inside the unit.

Key Features Of The Baxi 830
Baxi 800 Series:

The Easy-Fill Filling Loop Simplifies The Process Of Re-Pressurizing The Boiler.


All Baxi 800 combi boilers come with an Easy-Fill permanent filling loop, making it simple for homeowners to repressurise their central heating system without needing to call an engineer. This feature involves a single spring-loaded lever for quick and easy use.

Protect Your Central Heating System From Sludge Buildup.


Every Baxi 800 combi boiler is equipped with an Adey Magnaclean Micro 2 magnetic system filter to safeguard against sludge and debris buildup in central heating systems.

Sludge, which consists of rust particles from inside radiators and pipes due to corrosion, can lead to reduced boiler efficiency, cold spots on radiators, and potential breakdowns. The filter attracts and stores rust particles away from the system, preventing water flow disruptions and sludge formation.

During the annual boiler service, the MagnaClean filter can be emptied of accumulated sludge and debris, preventing them from clogging the heating system.

Additional Benefits of the Adey Magnaclean Micro 2 Filter:

  • Up to 6% annual savings on heating bills
  • Immediate and ongoing central heating protection
  • Extension of the central heating system's lifespan
  • Reduced carbon emissions.

Baxi uSense Smart Thermostat Can Control Your Central Heating System From Your Smart Phone.


Baxi 800 combi boilers work with Baxi uSense. Baxi uSense is a Wi-Fi thermostat you can control from your phone or tablet. It incorporates OpenTherm technology, enabling connection to various smart thermostats, including Baxi's uSense smart thermostat. The uSense thermostat is controllable via smartphone or tablet and provides boiler fault diagnosis.

Baxi uSense features include:

  • Better control
  • Set your heating schedule to match your routine.

High Energy Efficiency and Boiler Performance

The Baxi 830 Combi Boiler achieves an excellent ERP A rating, with an impressive efficiency of 93%. With a central heating output rating of 12.2 litres per minute and a domestic hot water output rating of 20 seconds, it offers impressive performance to effectively meet the heating and hot water needs.

Moreover, it can provide a strong heating and hot water supply for small to medium-sized homes, making it a reliable choice. Monitor your energy usage, optimise efficiency, and manage your bills.

A high-efficiency A rating for heating and hot water ensures lower energy bills and reduced carbon footprint.

Saving Fuel And Money Adjusting Its Power Output

These boilers become even more efficient when paired with a Baxi In Flue Outdoor Sensor (IFOS). The IFOS attaches to the flue and measures outdoor temperatures. Based on these readings, the boiler adjusts its power output to use just enough energy to keep the home warm.

For instance, if it's warm outside, the boiler will lower its temperature since less heat is needed indoors. This saves fuel and money and reduces carbon emissions while maintaining user comfort.

Meet Boiler Plus Requirements Easily & Affordably


Boiler Plus is a government rule that wants homes to use energy better by making heating systems more efficient. If you've got a new combination boiler, you need to add one of four things to make it meet the rules. Installing a Baxi IFOS does one of these things.

You can buy a Baxi IFOS (In Flue Outdoor Sensor) for about £30, which only takes a few minutes to install. So, it's a simple and cheap way to follow Boiler Plus rules!

Homeowners Can Receive A 10-Year Extended Warranty.


You get a 10-year extended warranty with all Baxi 800 range combination boilers, providing homeowners with extra assurance.

This is the longest warranty Baxi offers, highlighting their confidence in the reliability and performance of their 800 combi boiler range. Just remember, you need to meet specific terms and conditions to activate this extended warranty.

The Baxi 830 comes equipped with:

  • A compact size that fits in a 290mm deep cupboard, perfect for city homes where space is at a premium.
  • The Baxi 830 Combi Gas Boiler features brass hydraulics and a stainless steel heat exchanger.
  • It comes with built-in pipes and offers extensive flue options, up to 20 meters, simplifying installation and servicing for engineers.
  • The boiler includes an easy-fill loop, allowing quick pressure top-ups without needing a heating engineer.

Baxi 830 Installation

Installing the Baxi 830 is a breeze, owing to its straightforward hanging bracket design, ensuring quick and efficient installation. Its versatility extends to being wall-mountable, providing homeowners with flexible placement options. Moreover, installation costs for a boiler of this capacity are typically reasonable, adding to its appeal.

Baxi 830 Comparison With Other Boilers

In the bustling London boiler market, the Baxi 830 stands strong with its balance of efficiency, durability, and affordability. When compared to similar models in the range, it offers a noteworthy upgrade in technology and energy-saving features.

The Baxi 830 Combi Gas Boiler is a top choice for medium-sized homes because it's efficient, small, and has useful features like a built-in filter to keep pipes clean.

But it's smart to compare it with other models like the Baxi 800, Baxi 836, Baxi 825, and Worcester Bosch.

“The 830 is eco-friendly with 93% efficiency. It has smart controls for better heating control.”

  • Compared to the Baxi 800 series, the Baxi 830 gives more hot water and is smaller and lighter. It's not as powerful as the Baxi 836, but it still heats well.
  • Compared to the Worcester Bosch 30kw Combi Boiler, the Baxi 830 is smaller and cheaper but still works well. Both brands have good options for different homes.

Overall, the Baxi 830 Combi Gas Boiler is a strong choice with its efficiency, small size, and features. Homeowners should think about what they need in a boiler before picking one.

How Long Does It Take To Install A Baxi 830 Boiler?

The installation time depends on the type of boiler you currently have. If you're swapping a combi boiler for the Baxi 830 and it's staying in the same spot, it should be quick, usually about 4-6 hours.

But if you're replacing a different type of boiler with the Baxi 830 combi, like a regular or system boiler, it's more work. The old hot water cylinder and/or cold water tank will need to go, and new pipework will be installed to connect the combi boiler. This can take around two days for a gas engineer to complete.

How Much Is A Baxi 830 Gas Combi Boiler?

The boiler installation cost will vary depending on what boiler you are replacing. If you replace an old combi boiler and the location will be the same, installing it shouldn’t take too much work. Usually, installation fees range from £1000 to £2,000.

If you already have a system or regular boiler, more work will be involved. It usually takes one to two days to remove the cold water storage tank and hot water cylinder and install new plumbing.

The boiler installation cost typically ranges between £1,000 and £2,500, depending on the amount of pipework required.

Serviceteam heating engineers will assess factors like the number of rooms, bathrooms, and other relevant details to provide you with a comprehensive quote for the boiler installation. This ensures transparency, allowing you to know the exact cost upfront without any surprise fees later on.
