The Best LPG Boilers

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 boiler, you’ve come to the right place.

What is an LPG boiler?

LPG is short for Liquefied Petroleum Gas. These 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 this type of 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 an older non-condensing LPG-fired boiler with a more efficient brand new condensing boiler very easily. What’s more, like we have mentioned above, these boilers don’t actually need to be specially made. All gas boilers can be converted to LPG using a 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 of 2021

Below, we have put together a list of what we believe are some of the best boilers available on the market right now.  s 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

best lpg boiler viessmann 100-w

Model shown: Vitodens 100-W

Viessmann is 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.

Key Features:

  • Patented Inox-Radial stainless steel heat exchanger
  • Condensate and pressure release valve combined into one
  • Built-in shock arresters (reduces/avoids water hammer)
  • 10-year comprehensive extended warranty
  • Wall-mounted
  • Easy to use
  • Compact, making it easier to site
  • Lightweight

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.
