Combi Boilers FAQs

Understanding the world of boilers can often be a difficult challenge with so many manufacturers, models and types of heating systems to pick from. We always try to make our sales and installation
What is a Combi boiler?

A combi or combination boiler is usually a small sized boiler that combines the function of heating your central heating and heating your water. It is often used in small properties where space is short and a smaller boiler is needed to fit compactly in a tight space like a kitchen cupboard.

Combi boilers, or Combination boilers, are the most popular type of boiler in the UK. They're used by 74% of households.

They're named ‘Combination' because they combine a high-efficiency water heater and a central heating boiler all in one package.

Combi boilers are efficient and cost less in heating bills.

That's because:

They only heat water when you need it, rather than storing hot water up
They're small and compact, as they don't use an external hot water tank.

How does a combi boiler work?

Combi boilers work by remaining in a constant state of standby. This means that when a water tap is put on they quickly heat the water and deliver it to the tap hot. This is ideal for households that want to reduce the energy and cost inefficiency of having the heating system constantly on.

How much is a combi boiler?

he cost of a combi boiler depends on a number of different factors such as manufacturer, power output, size and the size of your central heating system. At Tyne & Wear Heating we're able to provide you with a quote in 90 seconds whilst also making sure that we pick the right boiler for you. We do this by asking a number of questions about your home such as how many bathrooms the property has, the positioning of your flue and how many bedrooms are in your house.

What size combi boiler do I need?

When you choose a combi boiler there are a few considerations to take into account regarding the size. Firstly, you may want a combi boiler to fit into a tight space, so you should take note of the boiler dimensions and measure whether it will be able to fit. However, it is vital that if you are looking for a boiler based on physical size that you make sure the boiler has a strong enough output that it can warm your home. As part of the questions we ask when we give you a quote, we ask about the size of your home, how many bedrooms you have and how many bathrooms are on the property. The answers to these questions will help us determine how powerful your new combi boiler needs to be.

How long does a combi boiler last?

There is no right answer for this question as each and every boiler is entirely different. The lifetime of a boiler depends on how it was installed, how it was maintained and how it was used. There are plenty of high quality boilers that can last for over 30 years. However, it is generally agreed by multiple industry sources that the average lifespan of a boiler is 10 - 15 years. This is likely to be less if the boiler hasn't received regular servicing and proper maintenance from a professional boiler engineer. However, Tyne & wear Heating protect the majority of our boilers with a 10 year warranty in order to ensure if something does go wrong, you can rest assured that you want be out of pocket to fix the problem.

What is the best combi boiler?

At Tyne & Wear Heating we don't believe that any particular boiler is best as there are a number of factors that will influence a boilers suitability for a property. However, we strongly advise customers that our BAXI combi boilers are some of the most reliable, energy efficient and cost-effective boilers that many homeowners can buy. BAXI regularly appear top in independent Which? boiler assessments and most of our BAXI boilers come with 10 year guarantees.

What temperature should hot water be set at combi boiler?

The temperature should be set to your own personal preferences, which obviously differ from person to person. Most combi boilers have separate temperature controls for the hot water and central heating system. If your boiler has two dials then you should aim to set the central heating control to circa 80°C whilst your hot water control should be set to meet your hot water requirements at a temperature between 55°C and 60°C.

Should a combi boiler be on all the time?

It depends on whether you're in the property all day. If you're not, it may be more energy efficient to schedule the central heating system to be turned off during the day when the property is empty. However, you may wish to program the heating to be on all day during the weekend or during the colder winter months.

Why does combi boiler drop pressure?

If your combi boiler is losing pressure (either suddenly or slowly over a period of time) it could be due to a leak on your central heating system. Sometimes these leaks aren't obvious and can't be seen because they are happening under floorboards.

What's the difference between combi boiler and condensing?

A combi boiler remains in a state of constant standby and doesn't require a water tank. Instead, when there is a demand for hot water, it quickly warms the water to a high temperature. Condensing boilers use the same technology but instead reduces the heat from flue gases, condensing the vapour produced by the boiler. This means that the energy efficiency tends to be slightly better.

What are the benefits of a combi boiler?

Combi boilers are incredibly energy efficient and affordable to run as the boiler system only activates when there is a demand for hot water. This can lead to reduced heating bills.

A combi boiler doesn't require a water tank so is often small enough to fit into small properties and into the tightest spots such as kitchen cupboards.

A combi boiler can be more environmentally friendly due to its high energy efficiency rating.

Do I need a water tank with a combi boiler?

No. Combi boilers don't require a water tank as they work by heating the water on demand. This means that combi boilers are energy efficient and often more affordable in running costs.

How much does a combi boiler cost to run?

The cost of running a combi boiler tends to be very affordable because the system only heats water on demand as supposed to remaining on constantly to heat a water tank. However, the running costs depend on factors such as the boiler's manufacturer, energy efficiency rating, how long it's been programmed to be on for, the level of hot water usage, the preferred temperature, size of house and even the local climate.

Can a power shower work with a combi boiler?

In general, a power shower requires a pump and water tank to function. Because a combi boiler doesn't require a water tank, your shower would take it's water pressure from the mains.

How much to replace a combi boiler?

Costs for replacing a combi boiler depend on the hot water demands of your home, the cost of your new boiler and installation. At Tyne & Wear Heating we provide one simple low-cost quote in 90 seconds with everything included. No upsells, no additional costs.

How to use a combi boiler efficiently?

You can ensure that your combi boiler runs efficiently for energy and cost by programming your thermostat to keep your heating system at your preferred temperature when you're home. If you work during the day and your home is empty, you may want to reduce the temperature or have the heating system turned to a lower setting during this time period. It is advised to not turn your heating system entirely off as more energy is required to bring your boiler up from zero. Alternatively, you can set your thermostat to automatically turn off when the room temperature reaches the optimum temperature to avoid the heating system from being constantly on.

Are combi boilers noisy?

You can ensure whilst no boiler is ever going to be virtually silent, a noisy combi boiler could indicate there is an underlying issue with the boiler or central heating system. Having your boiler regularly maintained and serviced will ensure that any boiler issues can be identified and rectified before the issue becomes too large to tackle or that your combi boiler runs efficiently for energy and cost by programming your thermostat to keep your heating system at your preferred temperature when you're home. If you work during the day and your home is empty, you may want to reduce the temperature or have the heating system turned to a lower setting during this time period. It is advised to not turn your heating system entirely off as more energy is required to bring your boiler up from zero. Alternatively, you can set your thermostat to automatically turn off when the room temperature reaches the optimum temperature to avoid the heating system from being constantly on.

General Boiler FAQs

Purchasing a new boiler can often be a daunting task. Boiler technology is always changing and if you’ve been fortunate enough to have had a great boiler installed correctly

How much does a new boiler cost?

The costs for:

  • a brand new A-rated boiler,
  • a brand new flue,
  • all the right fixtures, fittings and safety attachments,
  • installation from a Gas Safe Registered engineer
  • would traditionally set you back between £2,500 and £4,000.

Tyne & Wear Heating can offer you exactly the same A-rated boiler, flue, attachments and Gas Safe registered installation from as little as £6.50 a month, including VAT.

What are Thermostatic Radiator Valves?

Thermostatic Radiator Valves – or TRVs – are controls for your radiators. They regulate how much hot water flows into the radiator so you can adjust its temperature.

TRVs also let you turn some radiators off (for example, in a room you're not using) without turning off the heating.

Why do I need TRVs?
The Government recommends that every household has Thermostatic Radiator Valves because they:

  • save you money on heating bills
  • use less energy
  • are better for the environment
  • But they're not mandatory.

What's the cost?
Each valve costs £35. If you don't have them already we'll include them in your package and install them for you.

You'll get one for each bedroom.

I want TRVs for other rooms too
You can change the number of TRVs you receive before you check out.

I don't want TRVs installed
No problem. Just remove them from your boiler package before you check out.

What is a flue?

A flue is a pipe, like a chimney, that carries waste from the boiler outside. You can see your flue exit (the part of the flue that comes out of your house) on the wall or roof of your home.

Flues can either be square or round in shape.

If the flue is less than two metres off the ground, or underneath a carport or shelter, it'll be covered by a guard. This looks like a piece of wire mesh covering the end of the flue.

When you buy a boiler from BOXT, we'll also supply and fit a brand new flue for you, along with all the safety attachments you need.

What is the filter?

A magnetic filter, which we'll provide and install for free. It's fitted to the boiler on the return flow. This catches any debris from your system and stops it getting into your new boiler.

What is a Plume Management Kit?

A Plume Management Kit directs 'products of combustion' away from openings or vents into your property. This keeps you and your family safe.

Will my boiler work with solar power?

Yes. Your new Tyne & Wear Heating boiler will work with solar power in exactly the same way as your old boiler. Simply choose a solar-compatible boiler.

What is a system boiler?

System boilers heat your radiators directly and store hot water in a storage cylinder. They're usually installed in an airing cupboard or garage. They heat a large volume of water and then store it until you use it. This means they're less efficient than Combi boilers, which heat water only when you use it.

What is a Standard boiler?

Standard boilers are also known as Conventional or Regular boilers. They store hot water in a storage cylinder, like System boilers, but they're fed by a separate cold water tank – usually in the loft. There's another separate tank, called a ‘feed and expansion cistern', usually in the loft too. Standard boilers are the largest type of boiler.

What is an ErP label?

The Erp – Energy related products – Label tells you how efficiently a boiler (or another appliance like a fridge or a washing machine) uses energy. It's designed to help you choose the right appliance and pay less in energy bills. The label rates products from A+++ to G.

A+++ is the most efficient boiler you can get.

It also tells you how loud the appliance is in decibels and how much heat it outputs in kilowatts.

All of the boilers Tyne & Wear Heating sells are rated A for efficiency.

Boiler Maintenance FAQs

Below we have compiled answers to some of the frequently asked questions we receive via email, phone and social media about maintaining the boilers we install for customers.

Should I repair or replace my old boiler?

Replace. A repair can sometimes be as expensive as a brand new boiler. And you could easily have more problems with a repaired boiler further down the line.

A brand new boiler is usually more efficient and more reliable.

Your new boiler will be covered by warranty too – so if it breaks, the manufacturer will repair it with no extra charge.

We can provide a brand new A-rated boiler from as little as  £6.50 a month, including VAT and Gas Safe installation.

Will I get boiler cover?

Yes. Every new Tyne & wear Heating boiler comes with a manufacturer's guarantee of up to 10 years providing you continue to get it regularly serviced.

You don't need to do anything to activate your guarantee – we'll register your boiler with the manufacturer as part of our installation service. Please note that your guarantee is legally with the manufacturer, not with Tyne & Wear Heating.

Will you do a Chemical Flush?

Yes. We do a Chemical Flush – a hot flush and dose.

We'll put a cleaner into your system, flushing it around using the boiler. Any debris will be caught by the magnetic Omega TF1 filter we install for free. We'll keep going until it's clean.

Once the system is up to temperature, it's drained and refilled with clean water. Finally, an inhibitor is added to the water to protect the system.

Will you do a Powerflush?

No. After years of experience, we've found that using a Powerflush machine on an older system simply causes more problems.

Instead, we carry out a Chemical Flush – which is a highly effective way to keep your system protected, approved by our manufacturer partners.

What do I do if my boiler breaks down?

Don't panic. Get in touch with your boiler manufacturer and they'll send an engineer out as soon as possible. All Tyne & Wear Heating boilers come with a manufacturer's guarantee of up to 10 years.
