Baxi Duo-tec 28 LPG Combi LPG boiler frequently asked questions

Baxi Duo-tec 28 LPG - a combi boiler, system boiler or regular boiler?

If you’re looking for a combi boiler for your house or flat, you may wish to the consider the Baxi Duo-tec 28 LPG.

Combi boilers are excellent for providing hot water and heat for your radiators just when you need it. When you have a combi boiler installed in your home, you just turn on the tap and the hot water for your bath, shower, washing dishes and other activities is there when you need it. It also provides the heat you need to keep your radiators warm.

A combi boiler heats the cold water passing through it, which it draws from the mains. This newly heated water can then be distributed to whichever hot tap or radiator needs it.

In the past, boilers needed at least one storage tank to hold water that was either already heated or would be heated later. Sometimes, you'd have to wait for hot water because there was none left. In addition, storage tanks took up a lot of space and most UK homes are pretty small.

The main disadvantage to combi boilers is that they can only heat a certain amount of water at any one time, meaning the pressure, volume and temperature of water will decrease if more than one tap is on at the same time or if both the shower and washing machine are on together.

Is a Baxi Duo-tec 28 LPG combi boiler suitable for my house or apartment?

Selecting the right boiler for your property means selecting a boiler that is the right "size". And, by size, we don't mean how big it is, we mean how powerful it is - its "output".

The output rate tells you how much energy your boiler has to use to provide you and your family with hot water and central heating. A higher output rate means that it can heat greater volumes of water.

Please be aware, though - if you choose a boiler whose output is too low, the water in your radiators and coming from your taps may not be warm enough. Conversely, if you choose a boiler with too high an output, you'll pay more for lPG than is necessary.

The Baxi Duo-tec 28 LPG combi boiler has an output level of 25 kW, so which types of property would it be appropriate for?

A PlumbProud Gas Safe boiler installer would recommend that this Baxi Duo-tec 28 LPG Combi boiler be installed in smaller homes and apartments with one bathroom and up to 10 radiators.

When choosing a combi boiler like the Baxi Duo-tec 28 LPG, you need to consider the "flow rate" as well as the output rate. Flow rates (measured in litres per minute) indicate the volume of hot water that the boiler can heat up and then distribute to your taps and radiators.

However, combi boilers draw water from the mains and this means they can only heat the amount of water that actually enters your property.

What this means is that, if your mains pressure is 12 litres per minute, that is your boiler's effective flow rate even if it has the capacity to process 18 litres per minute. This Baxi Duo-tec 28 LPG Combi boiler's flow rate is 12 L/m.

To give you an idea of the flow rate you might need, a power shower typically requires around 12 litres of water per minute and a basin tap requires 4-8 litres per minute.

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 are the dimensions of the Baxi Duo-tec 28 LPG boiler?

The Baxi Duo-tec 28 LPG's dimensions are TBC mm [H] x TBC mm [W] x TBC mm [D].

Is the Baxi Duo-tec 28 LPG non-condensing or condensing?

Is the Baxi Duo-tec 28 LPG combi boiler an environmentally friendly choice?

As the British public has become more conscious of climate change, many homeowners consider the environment when choosing how to heat their homes.

Central heating creates 14% of the UK’s greenhouse gases. And in Britain's larger cities, gas boilers are responsible for dangerous levels of nitrogen dioxide emissions.

Would choosing a Baxi Duo-tec 28 LPG combi help the environment? Let’s see what the performance figures suggest.

What is the length of the warranty on the Baxi Duo-tec 28 LPG?

The manufacturer offers a parts and labour warranty of 7 years on the Baxi Duo-tec 28 LPG boiler to new customers.

Baxi Duo-tec 28 LPG Combi LPG boiler frequently asked questions

What type of boiler is the Baxi Duo-tec 28 LPG?

Baxi’s Duo-tec 28 LPG is one you might consider if you’re 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.

Is the Baxi Duo-tec 28 LPG combi boiler a suitable choice for my property?

Whether this Baxi Duo-tec 28 LPG Combi boiler is right for your property depends on its size or what its "output" level is. Size does not mean its physical dimensions, however - it means how powerful it is.

The output rating indicates how much energy a boiler can use in providing you with hot water and heat when you need it from your radiators and taps. The greater the output, the more water it can heat.

It's better to take advice on this from a registered installer because, if your boiler output is too low, your water and radiators might not get as hot as you would like them to be. However, if the output level is too high, you'll end up paying more on your lPG bills than you need to.

Which types of property would this Baxi Duo-tec 28 LPG Combi boiler be appropriate for given its output of 25 kW?

A heating engineer would recommend that the Baxi Duo-tec 28 LPG combi boiler would be a suitable installation option for smaller homes and apartments with up to 10 radiators and one bathroom.

You should also consider a combi boiler's "flow rate" when making your choice.

The flow rate indicates how much water it can take from the mains supply at any one time (measured in litres per minute), which it then heats and distributes to different points in your home like your bathroom, kitchen and radiators. This Baxi Duo-tec 28 LPG Combi boiler's flow rate is 12 L/m.

Combi boilers have no storage tanks like system or heat only boilers. This means that if the water pressure where you live is low, there's no benefit in spending money on a combi with a high flow rate because a high flow rate doesn't mean it can draw any more water from the mains.

In addition, there might be lots of people in your household who want to use hot water at the same time while also having the central heating on. Given that average mains pressure in the UK is between 10 and 12 litres per second and a power shower usually requires about 12 litres of water per minute, a combi boiler might not be the right choice for you and your family.

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.


How big is the Baxi Duo-tec 28 LPG?

The Baxi Duo-tec 28 LPG is TBC mm tall, TBC mm wide, and TBC mm deep in size.

Is the Baxi Duo-tec 28 LPG non-condensing or condensing?

Is the Baxi Duo-tec 28 LPG combi environmentally friendly?

As more of us become concerned by the effects of climate change, the damage we do to the environment by heating our homes has emerged as an important issue for many homeowners.

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.

If you decide to install a Baxi Duo-tec 28 LPG combi in your home, will you be helping the environment with your choice? Let’s have a look at the figures.

How many years does the warranty period cover on a Baxi Duo-tec 28 LPG boiler?

A parts and labour warranty of 7 years is included with the Baxi Baxi Duo-tec 28 LPG boiler.
