Buying A New Caravan Boiler

You might be unaware, but many new options have been introduced since you have bought your beloved caravan. You don’t need to replace your old boiler with a similar one. You should be open to change as it can be very beneficial for you in many cases.

Before you choose your new boiler, have a look at these different types of boilers you can buy to ensure you’re really getting the best option for your situation and circumstances:

Electric Boilers For Caravans

There was a time when you could buy gas boilers. With the evolution of technology, other options like electric boilers and hybrid boilers have also emerged. These options are more compact and offer more effective than their predecessors.

In the case of gas boilers, you have to wait at least half an hour for the water to get hot enough to take a bath. Electric boilers reduced this waiting time to half. If you install an electric boiler in a caravan, you will get hot water in just 15 minutes.

Moreover, getting a gas connection from the main for just a boiler is also a daunting task. It involves a lot of paperwork and also takes a considerable amount of time. If you are thinking about getting LPG, then prepare yourself for carrying extra weight. In addition, the space in your caravan will also be compromised due to LPG cylinders.

Last but not least, an electric boiler will save you money in the long run. Running a gas boiler will cost you money in several ways. Gas cylinders require periodic maintenance, and if you do the math, gas costs more than electricity. Here we are talking about LPG cylinder gas and not about the connection from the main.

Connection from the main could be more economical depending upon your area.

Gas Boilers For Caravans

The second type of boilers that you can buy is the gas boilers. You will witness these traditional boilers in most of the old caravans. They can run on both, LPG or from the main connection. If you have a touring caravan, then you will have to rely on the LPG cylinders only.

Moreover, you will have to stop repeatedly in order to refill LPG gas. Sometimes, you will even have to go out of your way to top up these tanks. Due to the presence of these cylinders, you will also compromise your security.

On top of that, gas boilers take more time to heat the water than electric boilers. They are sufficient if you are two people but not a suitable option for people more than that. The cost factor is also there.

In most cases, electric boilers are more economical than gas boilers.

Hybrid Boilers For Caravans

The most advanced types of boilers are hybrid boilers. As the name states, these boilers are a mix of gas and electricity. Although these boilers are relatively costly than both electric and gas boilers, they are worth it.

Hybrid boilers are more effective and more practical than all the other options available on the market. They use both gas and electricity to heat the water. This significantly reduces the overall time required for heating the water.

Besides that, if you are short on one source, you won’t have to miss a good warm shower. You will have to wait a little longer, but it is better than staying untidy.
