Vaillant Boilers Prices (Updated 2023) - How Much Is a Vaillant Boiler? (2023)

FAQs

Why are Vaillant boilers so expensive? ›

Vaillant isn't the cheapest boiler brand on the market.

Well, none of the boiler prices below can compete with that, and there's a reason for it. Much like Worcester Bosch, Vaillant is a premium boiler brand. They focus on efficiency (and therefore, savings on energy bills), reliability, practicality and warranty.

The cruise ship will measure 278m long and 38m wide and will have a gross registered tonnage of 110,000t. It can carry more than 2,700 passengers and 1,150 crew members.

For an average household, boilers will last up to 10-15 years. Though it's important to understand this timespan is conditional.

If you're connected to mains gas, you're looking at a cost of around 11.51p per kilowatt-hour. This means that if you have a 24 kW boiler, you can expect to pay around £2.76 per hour to run it on mains gas. Information correct as of the October 2022 price cap.

Our industry sources tell us that Vaillant appear to be experiencing shortages, with Vaillant boilers becoming increasingly difficult to source.

Upgrade to a modulating thermostat

Upgrading from an on/off thermostat to a modulating thermostat is a quick and easy way to make your home more comfortable and lower your heating bills as it accurately measures the temperature of your home and will actively control the boiler to meet the desired level of warmth.

The exact recommended pressure level will vary depending on the boiler manufacturer, but generally, anywhere between 1.0 and 2.0 bar is ideal. The boiler pressure level will rise when heating a home or providing hot water. However, it should still stay below the upper-pressure limit of 3 bar.

The advantages of a Vaillant gas-fired condensing boiler:

Optimum energy efficiency of up to 98% Significantly less soot and particulate matter during combustion via condensing technology. Consumption drops by up to 30% compared to an old heating installation.

There are already 400,000 conventional boilers made every year at the site, but the new heat pump production line comes amid rising demand for greener and more efficient devices. The facility makes Vaillant's Derbyshire factory the first to produce both heat pumps and boilers in the UK.

How often should a Vaillant boiler be serviced? ›

How often should I get my boiler serviced? Boiler servicing should be carried out once a year to ensure that a boiler is properly maintained, supported and in good working order.

You can activate an extended 10-year guarantee on a selection of Vaillant domestic boilers.

A new, well-maintained boiler is a lot more energy efficient than an old boiler. As a result, an efficient boiler can help cut energy costs. Even though it's a big upfront cost to install a new boiler, it'll be offset by the savings you make on your bills in the long term.

Condensing gas boilers are the most cost-efficient. Gas is the cheapest fuel compared to electricity, oil, coal, and LPG. You can also switch to a low-carbon heating heat pump that reduces the cost depending on the fuel type and system you are replacing.

Normally, when purchasing your boiler, this time is usually set at 20 minutes, and for most properties, this works fine. However, if you want to change this time, you can set it to any value between 2 minutes and 60 minutes. To determine the ideal waiting cycle for your radiator, consult your boiler manual.

Innovation charity Nesta suggests a flow temperature of 60°C, or slightly lower if your home is particularly well insulated. If you or anyone in your household is more vulnerable to the cold (for example the elderly or those with underlying health conditions) please don't set your flow temperature below 60°C.

Turning a boiler off may seem a sensible way to save money - but it's 'not recommended' Experts warn that turning your boiler off to save money might seem sensible - but it can actually end up costing you more.

Reducing the flow temperature also lowers the return temperature. All boilers are more efficient when the return temperature is low, and this can save you energy and money.

Is 25 psi too high for boiler? ›

Most boilers are safe up to around 30 psi, at which point seals can begin to fail. Modern boilers aren't nearly as dangerous as early steam engines , but you can still damage them and require costly repairs. Provided your boiler stays in the 12-30 psi range, you're in no real danger.

For a modern combi boiler, the radiator heating temperature should be set for a flow temperature of between 60 and 70°C. Any higher than this and the boiler won't enter condensing mode and be at its optimum efficiency and performance.

High-pressure steam boilers create steam at above 15 psi. In practice, industrial high-pressure boilers often operate at hundreds of psi. They also operate at considerably higher temperatures than low-pressure boilers.

1.Viessmann Vitodens 100-W 30kW model

The top spot for the most energy efficient combi boiler of the year 2023, which produces the # 1 “best combination,” for most average-sized UK homes is the Viessmann Vitodens 100-W 30Kw.

If your new boiler is too small, it might not be powerful enough to properly heat your home, or give you enough hot water. On the other hand, getting a bigger boiler than you need could lead to wasted energy which'll take its toll on your bills and on the environment.

System boilers, also known as sealed system boilers, are the perfect solution for larger family homes where you might have many people using multiple sources of hot water at the same time.

About Vaillant

Vaillant is a German family-owned business and have worked hard to establish their brand in the UK since entering the market in the 1970s.

About the Vaillant boiler company

Vaillant are a German-based heating brand that has over a century's worth of experience in the industry.

The answer is yes, a boiler can last for 30 years or even more, but as with any piece of equipment, its longevity is dependent on a number of factors. In this post, we will focus on high-pressure steam boilers for industrial and commercial applications and how best to extend their lives.

Can a boiler last 50 years? ›

The standard modern hot water boiler will last around 20 years, sometimes more. Older cast iron steam boilers can last longer, and may even reach 50 years—but this is rare, and you probably don't have a cast-iron steam boiler.

In general, standard boilers last between 10 and 15 years in a usable state with minimum maintenance, although sometimes they might last 20 years. Beyond that, though, it's certainly worth upgrading.

How Long Does It Take to Install a Vaillant Boiler? Boilers come with an installation period of between one to three days, depending on the complexity of the job.

Fortunately, switching off your boiler at the mains is perfectly safe.

How long does it take to replace a heating system? Normally a like-for-like boiler swap can be done in a day. This will obviously depend on how much other work is needed to upgrade your system to meet latest efficiency guidelines. Don't forget, your new Vaillant boiler will work at it's best using Vaillant controls.

Your Advance installer must then register your new boiler system through our 'Vaillant Advance Loyalty Scheme' to validate your free 10-year guarantee. We also offer guarantees of up to 7 years on our ecoTEC pro and ecoFIT pure ranges when installed by a Vaillant Advance Installer.

Some of these boilers can last even up to 50 years or longer, but even with decent annual maintenance, their efficiencies are much lower than today's cast iron boilers. Often times, the energy savings from a new boiler replacement alone practically pays for the cost itself within a year or two.

How Old is my Vaillant Boiler? Vaillant boilers will usually have their serial number stuck somewhere on the outside casing of your boiler. The third and fourth numbers of the serial number reveal the year your boiler was manufactured.

This is due to the labour of running the new pipework and the cost of the materials required. If your new boiler location is in the same room or fairly close to the old location then it should take between half a day to a day to move.

Out of the components listed for a combi boiler, the most expensive ones tend to be: The heat exchanger. The electronic control board. The diverter valve.

How long does it take to install a boiler? ›

However, as a broad estimate, a new boiler installation will take between six hours and four days. We'll break down some examples below to give you more of an idea and explain the process in further detail.

Although Viessmann and Vaillant both offer solid boilers and both brands are A-rated by the EPC register, we think it's safe to say that in the battle of Vaillant vs. Viessmann, Viessmann has come out on top! Viessmann boilers are technologically superior and use Inox-radial stainless steel heat exchangers.

The most common type of boiler system especially for industrial uses, fire tube boilers, has been around for a long time because of their ability to meet steam needs when the demand is large and constant. These pressure vessels are filled with water, and the fuel used to heat the water is kept inside a series of tubes.

Gas boilers, on the other hand, are the cheapest way to heat a house since they are more affordable to run than electric boilers.

Turn down your heating to save gas

It sounds simple but turning your heating down is one of the best ways to save on your annual energy bill. This also includes your combi boiler temperature too on your boiler settings.

The Vaillant Group is a company that develops products for heating, cooling and hot water. The company employs ~16,000 people worldwide and generates an annual turnover of approximately 3.3 billion euros.

Electric heat is the most expensive type of heating. To get cheaper heat using electricity you need to use a heat pump.

Compact Choice – If you live in a flat or a small home where space is an issue then the more compact ecoFIT Pure is the best choice Vaillant system boiler. High Output – If you have a high heating and hot water demand, then the ecoTEC Plus 48 & 64kW is the system boiler for you.

What are alternatives to Vaillant? ›

For a modern combi boiler, the radiator heating temperature should be set for a flow temperature of between 60 and 70°C. Any higher than this and the boiler won't enter condensing mode and be at its optimum efficiency and performance.

If you have a conventional boiler system, your water cylinder will have its own thermostat. This is usually fitted on the side of the tank. You should set the temperature between 60 and 65 °C but for maximum efficiency, it should be set to around 60 °C.

Natural gas is likely to prove the cheapest way to heat a home if you have this heating option available to you where you live. Although prices have risen, natural gas is the least costly form of space heating. This is followed by electricity, propane, and heating oil, from the next cheapest to the most expensive.

Furnaces and boilers powered by natural gas offer some of the cheapest forms of energy for heating. Furnaces cost $2,000 to $17,000 to install, while boilers cost $1,800 to $16,000. Furnaces that burn pure heating oil aren't environmentally friendly, while boilers use water or steam.
