System boilers are quite a popular type of boiler. If you’re thinking about using LPG as a heating fuel, you should definitely consider installing an LPG system boiler.
Before you make a decision on the boiler you’re going to install it’s important to know all the facts. Keep reading to find out the pros and cons of LPG system boilers.
LPG system boiler pros
LPG suits homes without access to mains gas
Mains gas is usually the best heating fuel to use in your home as it’s by far the cheapest. But if your home isn’t connected to mains gas, LPG is a great alternative heating fuel. Not only is LPG usually cheaper than coal and electricity, it also produces less carbon dioxide than heating oil.
System boilers can supply hot water to multiple outlets
A big advantage to system boilers is that they can supply hot water to multiple outlets without a drop in pressure. This is because they heat water in advance, so there is a good supply to go wherever it’s needed. This is different to combi boilers, which normally struggle to supply multiple outlets with hot water without a drop in pressure.
Smaller than a conventional boiler
System boilers are also popular because they take up less space than conventional boilers. This is because, unlike conventional boilers, they don’t have a cold water tank. So if a combi boiler isn’t for you, but you don’t have room for a cold water tank, an LPG system boiler could be for you.
LPG system boiler cons
They don’t always provide hot water on demand
A downside to system boilers is they only heat water in advance. The amount of hot water they heat is limited to the size of the tank, so will run out at a certain point. You can turn your boiler on to heat up more water but this will take time. So if you want a boiler that will provide you with hot water whenever you want it, you’d probably be better off with a combi boiler.
Bigger than a combi boiler
Another disadvantage to system boilers is that they take up space. Although they take up less room than a conventional boiler, they’re much bigger than a combi boiler. You’ll also need some outside space where you can store your fuel. So if you want the smallest boiler you can get, an LPG system boiler may not be for you.
LPG is more expensive than some other fuels
You should also bear in mind that LPG isn’t the cheapest heating fuel around. Mains gas is much cheaper and you may find that heating oil is too. The best thing to do is compare energy prices in your area before you go ahead and commit to a new boiler.
So if you’re considering getting a new boiler, an LPG system boiler is worth considering. To find out more about other heating options, take a look at our articles on combi and conventional boilers.
