The Best Boilers For Caravans

Published: 12 May 2025 ・ Read time: 5 Mins

All UK caravan owners need to ensure that their caravan is equipped with a good quality, reliable boiler to ensure both a comfortable and indeed safe space.

When considering installing or maintaining a boiler in a caravan, most caravan owners will look to the professionals for guidance. With the expertise and experience to ensure that the right boilers are installed, correctly and safely, those in the trade are well placed to provide valuable advice on the best type of boiler for the customer’s specific needs.

Here at City Plumbing, the home of heating, we explore several of our best-selling boilers that are best suited to caravans.

The Importance of a Good Boiler For The Caravan

Having a good boiler in a caravan is crucial for several reasons. Firstly, a reliable boiler will provide users with hot water for showering, washing dishes, and other daily tasks. This is especially important for those caravans on the road that may not have instant access to other sources of hot water.

Additionally, a good boiler can help maintain a comfortable temperature inside the caravan, which is especially valuable during colder months.

Finally, a good reputable boiler that is the right size and type and is regularly serviced will promote a safe caravan for all users.

What Types of Caravan Boilers Are Best?

For caravans in the UK, Liquid Petroleum Gas (LPG) boilers are generally considered the best option due to the widespread availability of LPG bottles and their cost-effectiveness compared to electricity for heating. Here's a breakdown to help your customers choose the best boiler for their caravan:

LPG Combi Boilers: These are the most popular type for caravans as they provide both central heating and hot water without needing a separate hot water cylinder. They are compact and efficient.
LPG Water Heaters: These units only provide hot water and are a simpler and often more budget-friendly option if central heating isn’t required.
Electric Boilers: While less common due to higher running costs, electric boilers are an option if customers primarily stay on sites with electric hook-ups.
Combination Boilers (Gas & Electric): Some units offer the flexibility of using either gas or electricity, or both, for faster heating.

Key Considerations For Choosing The Right Caravan Boiler

Size and Space: Caravans have limited space, so a compact boiler is essential. Consider the dimensions of the unit and where it will be installed.
Heating and Hot Water Requirements: Determine if the customer needs just hot water or both heating and hot water. This will dictate whether they require a water heater or a combi boiler.
Fuel Type: LPG is the most common and often most economical for caravans in the UK. Ensure the boiler is compatible with LPG.
Efficiency: Look for boilers with high-efficiency ratings to help customers save on fuel costs.
Warranty: Check the length and terms of the boiler warranty for peace of mind.
Budget: Boiler prices vary depending on the type, brand, and features. Discuss the customer’s budget and help them compare different models within that range.
Installation and Maintenance: Consider the ease of installation and the availability of servicing and spare parts.

For safety, any LPG boiler or water heater should only be installed by a Gas Safe registered engineer. For best practice, stay updated on those specific regulations or safety standards for gas appliances in caravans in the UK.
