Vokera Compact A 25A Combi Gas boiler frequently asked questions

What kind of boiler is the Vokera Compact A 25A - standard, combi or system?

The Vokera Compact A 25A is worthy of consideration if you're looking for a combi boiler for your flat or house.

Traditional boilers have one or more large tanks in which they store either heated water or water to be heated later. Manufacturers originally introduced combi boilers to the market in the 1970s to enable homeowners to save space - UK residential properties are among the smallest in the Western world.

Combi boilers don't need these tanks because they draw water directly from the mains and instantly heat it on demand thanks to the technology inside the boiler. Combi boilers then distribute this hot water to your home’s taps and radiators when needed.

The most significant disadvantage of combi boilers is that they are not ideal in larger homes where multiple people might want hot water at the same time – for example, if someone is having a shower while another wants to wash dishes in the kitchen. This is because combi boilers have a maximum volume of water that they can heat. When two people want hot water at the same time, the water temperature, pressure and volume delivered to both points drop.

Should I install a Vokera Compact A 25A combi boiler in my home?

To determine that, we need to consider the size of the boiler. Size doesn't mean how big it is - it means how big its "output" is.

Your boiler's output indicates the maximum amount of power available to it to heat the water you need to warm your radiators or when you want hot water from your taps. A higher output rate means that your boiler is capable of heating greater volumes of water.

If a boiler's output rate is too low, you'll often find that the water is not as hot as you want it to be. Too high, however, and you'll end up paying more for your gas than you should be.

The Vokera Compact A 25A combi boiler has an output rate of TBCkW, so which types of property would this be suitable for?

Most Gas Safe engineers would suggest that the most suitable type of property for installing a Vokera Compact A 25A combi boiler would be smaller homes and apartments with up to 10 radiators and one bathroom.

You'll also need to be sure to choose a combi boiler with the right flow rate for your home.

The flow rate indicates the maximum volume of hot water (measured in litres per minute) that your boiler can distribute at any given time. This means that if you and your family are likely to be using several taps and showers simultaneously or you have a lot of radiators, you need a boiler with a high flow rate. This Vokera Compact A 25A Combi boiler's flow rate is TBCl/m.

As with all combi boilers, the Vokera Compact A 25A is only able to heat and distribute water at the rate at which it actually enters your property.

For this reason, you shouldn't purchase a boiler with a very high flow rate if the flow rate in your mains pipes is lower because the extra capacity doesn't mean it can draw more water from the mains pipes.

When our engineer comes out to quote you, they may recommend that you choose a heat only boiler or system boiler instead if your family's demand for hot water is higher than normal.


Making space for the Vokera Compact A 25A

The Vokera Compact A 25A boiler measures TBC mm [H] x TBC mm [W] x TBC mm [D] in size.

Is the Vokera Compact A 25A condensing or non-condensing?

Condensing gas boilers like the Vokera Compact A 25A are more energy-efficient and choosing one for your home will cut the amount you pay every year for your gas.

They do this by capturing the heat in water vapour condensation and in exhaust gases which would normally be expelled via the flue. They then recycle that heat, returning it to the system to, among other tasks, reheat colder water that is returning to your boiler from your radiators.

Is the Vokera Compact A 25A combi an environmentally friendly boiler?

Concern for the environment is causing more and more homeowners to think about how they heat their homes and its impact on climate change.

About 14% of the greenhouse gases we produce in the UK come from the power needed for central heating. In bigger British cities, gas boilers are a significant source of nitrogen dioxide emissions.

Is the Vokera Compact A 25A combi an environmentally friendly choice for your home? Let’s have a look at the figures.

All new British boilers must perform to a legal minimum energy efficiency of 92% (a low to good SEDBUK "A" rating). Prior to April 2018, the target was 88% (86-90% = SEDBUK "B" and 90%+ = SEDBUK "A").

Efficiency ratings are intended to let consumers know how much energy a boiler uses in its day-to-day activities and how much energy goes to waste.

The Vokera Compact A 25A was awarded an efficiency rating of 93%, equivalent to a SEDBUK grade of "A".

What length of warranty does the Vokera Compact A 25A come with?

The Vokera Compact A 25A is covered by a parts and labour warranty of TBC years following installation.

Vokera Compact A 25A Combi Gas boiler frequently asked questions

Is the Vokera Compact A 25A a combi, system or regular boiler?

You may wish to consider installing the Vokera Compact A 25A if you are looking for a combi boiler for your house or flat.

In the past, most boilers needed one or more storage tanks to operate - one to store warm water and the other for storing water to be heated later. But storage tanks are problematic in properties where space is at a premium and particularly where there is no loft. Many properties in the UK are small and so manufacturers introduced combi boilers in the 1970s to eliminate the need for tanks.

With a combi boiler, the hot water for your radiators and taps is delivered on demand. The boiler instantly heats water it draws directly from the mains internally. It then distributes the heated water around your home at mains pressure as you need it.

It is important to bear in mind that, while combi boilers have many benefits, they can only heat a certain volume of water at any given time. This means that, if you run a shower at the same time as someone else is doing the washing up in the kitchen, the volume of water passing to each point will drop, causing a fall in pressure.

Should I choose a Vokera Compact A 25A combi boiler for my house or flat?

It's best to choose a boiler whose size or "output" is right for your home.

The more hot water and heat you want, the higher the output level of your boiler should be. Output is measured in kilowatts and it describes the maximum level of power your boiler has to heat water.

If your output level is too low, your boiler will not have the power it needs to get your water as hot as you want it, particularly when there's a lot of demand for it. Choose a boiler whose output level is too high and you'll have all the hot water you need but will be paying too much for it through higher gas bills.

Which types of property would this Vokera Compact A 25A Combi boiler be appropriate for given its output of TBCkW?

A PlumbProud boiler engineer would recommend that this Vokera Compact A 25A Combi boiler is suitable for smaller homes and apartments with up to 10 radiators and one bathroom.

Please remember to consider "flow rates" as well when choosing your new boiler. All combi boilers including the Vokera Compact A 25A draw water from the mains.

Each combi boiler has its own flow rate (measured in litres per minute) - this tells you how much water it can heat and distribute to your home’s taps and radiators straight from the mains. This Vokera Compact A 25A Combi boiler's flow rate is TBCl/m.

There is no benefit to you in choosing a combi with a high flow rate if your mains pressure is low - save money by buying a boiler whose flow rate is equal to or slightly more than the pressure in your water pipes.

In addition, if you have a lot of radiators and bathrooms in your home or you have a large household that often uses lots of hot water at the same time, like for regular morning and evening showers, a combi boiler may not be suitable.

When our engineer comes out to quote you, they may recommend that you choose a heat only boiler or system boiler instead if your family's demand for hot water is higher than normal.


What size is the Vokera Compact A 25A boiler?

The Vokera Compact A 25A's dimensions are TBC mm [H] x TBC mm [W] x TBC mm [D].

Compact A 25A – condensing or non-condensing?

This Vokera Compact A 25A is a condensing gas boiler - we always recommend that clients choose the latest condensing models to benefit from the technology, which continues to improve year after year.

Condensing boilers capture the heat still present in flue exhaust gases and water vapour condensation, processing them through a secondary heat exchanger to, among other tasks, heat colder water returning from your radiators.

By selecting a modern condensing boiler, you'll save money on your gas bills as well as benefitting the wider environment.

Is the Vokera Compact A 25A combi good for the environment?

How we heat our homes has become a pressing issue of concern for many homeowners worried about climate change and the environmental impact of their personal choices.

As much as 14% of the UK’s greenhouse gas production derives from our domestic central heating systems. Gas boilers are responsible for dangerous levels of nitrogen dioxide emissions in Britain's largest cities.

Will you be helping the environment if you decide to install a Vokera Compact A 25A combi in your home? Let’s look at the figures.

Under current UK law, all boilers must achieve a minimum energy efficiency level of 92% (a low to good SEDBUK "A" rating). The minimum level was raised from its previous 88% in April 2018.

Energy efficiency scores are intended to inform consumers of the amount of energy used and wasted when a boiler is in normal operation.

The Vokera Compact A 25A was awarded an efficiency rating of 93% with a SEDBUK band rating of "A".

Will I be covered if the Vokera Compact A 25A combi breaks down?

The Vokera Compact A 25A is supplied with a parts and labour warranty of TBC years.
