Wherever you live in the UK, everyone would prefer a mains gas connection. But in its absence, the best options you have are either an LPG boiler, an oil boiler, an electric storage heater or an air source heat pump.
For most people living on the UK’s mains gas grid, the thought of anything other than mains gas for their boiler and central heating system may sound strange. It may even sound too complicated. However, there are actually around 4 million households up and down the country who are not currently connected to the UK’s mains gas supply. Most of them either use an LPG boiler or an oil boiler. If you are living off the mains gas grid, and are looking to replace your existing oil or LPG boiler, you’ve come to the right place.
What is an LPG boiler?
LPG is short for Liquefied Petroleum Gas, and LPG boilers differ from ordinary gas boilers in that the LPG is delivered in trucks and stored in a special tank or cylinders, similar to heating oil for oil boilers. Whilst LPG is stored as a liquid-like oil, however during operation when it is being used, it is drawn in as a gas. There are some boilers specially designed to work with LPG. However, gas boilers can be converted to utilise LPG with a simple conversion kit, without affecting the boiler’s overall efficiency levels.

How does an LPG Boiler heat your home?
This form of fuel and boiler system is generally used in a system that uses ‘wet heating’. In this system, the water is heated by an LPG fired boiler and this heats the property through the hot water pipes and radiators, and gives you hot water through the taps. The fuel doesn’t come through pipes from the gas grid, as is the case with Mains Gas. But instead you store LPG in tanks outside your property, or in cylinders near your boiler.
So, if you’re used to mains gas all your life, this may look vastly different. Some examples of how LPG is stored in off-grid homes are shown below:
The benefits of LPG boilers
One of the biggest benefits of using an LPG boiler is the fact that liquid petroleum gas is a very efficient form of fuel. This means that you will receive a very good return on investment for each and every energy unit. However, a fact that is worth considering is that current condensing boilers use better designed hot-flue gases, which used to go to waste in older, non condensing boilers. This helps modern condensing boilers achieve energy efficiency of 92% and above and even 98% for models like the Viessmann Vitodens 200-W.
You can replace a an older non-condensing LPG-fired boiler with a more efficient brand new condensing LPG boiler very easily. What’s more, like we have mentioned above, LPG boilers don’t actually need to be specially made LPG boilers. All gas boilers can be converted to LPG using an LPG conversion kit. So, when we’re talking about the best LPG boiler, our list doesn’t really differ much from our which boiler is best list.
The best LPG boilers 2021
Below, we have put together a list of what we believe are some of the best LPG boilers available on the market right now. As there are no boilers that are made exclusively for LPG, we have highlighted the ones that can be easily converted for use with LPG, if that is your current setup in your property.
1. Viessmann Vitodens Open Vent 100-W
Viessmann are a name you should know, if you don’t already, as they have an impressive reputation for designing and manufacturing some of the highest efficiency A-rated condensing boilers on the market. Take this Viessmann Vitodens, for instance, which is capable of energy efficiency of around 97%, which easily scores it an A rating. Which also takes it over and above efficiency levels outlined in the Boiler Plus legislation. Besides, if you’re paying a good price for a high efficiency boiler, it’s not just to conform to some legislation, but you do that so you can save money on energy bills over the long term, and also because you want a high-end, technologically advanced boiler in your home.
One of the biggest advantages that Viessmann have over other boiler manufacturers is the fact that they use patented Inox-Radial Stainless-Steel Heat Exchangers, which are not only more durable and resilient than the aluminium heat exchangers used in many competitor boilers, they are also extremely resilient to corrosion. This means they will last longer, and be just as efficient 10 years down the line. Viessmann has this component throughout their impressive boiler range.

2. Worcester Bosch Greenstar I
Worcester Bosch is an incredibly popular and successful boiler manufacturer who have been in business for a long time now. Their market share in the UK is testament to that. However, we do feel they have rested on their laurels far too long now, and need to innovate to be relevant with modern technological progress. Especially against manufacturers like Viessmann. Having said that, their Greenstar I deserves its place in this list of the best LPG boilers.
It is capable of achieving as much as 92% energy efficiency and has an A rating. This boiler can manage flow rates of close to 12.3 litres a minute.

- Rear piping
3. Ideal Vogue
Undoubtedly, the Ideal Vogue is one of the strongest and best performing condensing boilers on the market. It can achieve a flow rate of around 16.4 litres a minute and comes with a standard warranty that covers you for 10 years. Ideal has taken on a “cheap boiler” reputation, and are not always spoken about with the bigger names, but this is definitely a good boiler that you should not pass on so easily.
This boiler is capable of achieving energy efficiency of up to 89.10%, and therefore, is lower in terms of its energy efficiency than others, but still has an A Rating.
- Crystal clear LCD monitor display for easy use
- Error and fault logging
- Easy to use
- Easy to maintain
4. Vaillant EcoTec Plus
Vaillant is a boiler manufacturer who has been making a good name for themselves for a long time now and is definitely one of the biggest names in the UK boiler industry. The Vaillant EcoTec is a stunning combination of versatility and good value. It has very easy to use controls and is considerably smaller than a lot of other models on the market for similar prices.
The Vaillant EcoTec Plus boiler is capable of achieving 89.2% energy efficiency. Although this is lower than some, it is still awarded an A rating.
- Easy to use and maintain
- Smaller size
- Output modulation built-in (this helps to make sure you don’t use more energy than you actually need)
5. Potterton Promax SL
Along with Ideal, Baxi, Vokera, Ferroli etc. Potterton are known as one of the “cheap boiler” manufacturers in the UK. However, Potterton can be good at designing and constructing effective and efficient LPG boilers. The Potterton Promax SL is one of the most popular standard boilers available at the moment. And with good reason. It is actually capable of achieving as much as 91.1% energy efficiency and therefore has an A rating. You need to be aware though that some of the older, bigger models of the Potterton Promax are still available and they are only B rated and capable of 86.4% energy efficiency. So you need to check that what you are being sold is a newer and updated model.
- Moderate to high efficiency
- Easy to use
