Hot Water In Campers: Diy Guide To Warmth And Comfort

Getting hot water in your camper is a must for many people, especially if you want to take a hot shower or wash the dishes. There are several ways to get hot water in your campervan, from boiling water on a stove to using a solar shower or installing a water heating system.

One popular option is to use a tankless propane water heater, which heats water on demand and is easy to install. Another option is to use a water tank, which can be heated using gas, electricity, or diesel. Combi heaters are also available, which heat both water and air, saving space and energy.

For those who want an off-grid solution, a calorifier water tank uses waste heat from the engine to heat water, providing hot water without any additional energy sources. This method may not be suitable if you're staying in one place for a few days, as you'll need to run the engine to heat the water.

Other options include using a log burner or solar power to heat water, although these may not be as reliable or efficient as other methods. Ultimately, the best solution depends on your personal needs, budget, and how much hot water you require.

Boiling water on a stove

To boil water on a stove, you'll need a cooking pot or kettle and a source of heat, such as a campfire, camping stove, or built-in cooktop. If you're using a campfire, build a fire and let it burn down to coals. Place the pot or kettle on the coals and add small kindling around it. Keep feeding the fire with small sticks until the water boils. Remember to keep the handle away from the flames and use a thick glove or a stick to remove the pot when the water is ready.

If you're using a camping stove, simply place the pot or kettle on the stove and follow the instructions to start the stove. This method is faster and easier than boiling water over a campfire.

When boiling water, always use a stainless steel or cast iron pot or kettle. Avoid non-stick pots and those with plastic handles, as they can melt. Additionally, if you're boiling water for drinking, be sure to source the cleanest water available and strain it through a cloth or handkerchief before boiling to remove large particulates.

Boiling water is also an effective way to purify water for drinking. The high heat makes the water an unsustainable living condition for most bacteria, parasites, and viruses. To make water safe to drink, let it boil for at least one minute at low elevations or up to five minutes at high altitudes.

Solar showers

The Advanced Elements 5-Gallon Summer Shower is a popular choice and combines ease of use, durability, and capacity to provide a long enough shower. It has a plastic quick-release buckle on the handle, making it easier to hang than other models. It also comes with a shaving mirror. However, the showerhead provides a slow flow.

If you're looking for a more compact and affordable option, the Nemo Helio Pressure Shower is a good choice. It has a built-in foot pump for adding pressure, so you don't need to hang it up. It holds 3 gallons of water and rolls up to the size of a can of coffee for easy portability.

The Sea to Summit Pocket Shower is ideal for backpackers as it is lightweight and packable. It has a wide-opening roll-top that makes it easy to fill from a hose, faucet, or stream. However, it takes longer to heat up due to its smaller volume.

When using a solar shower, it's important to hang the bag high enough so that you get adequate water pressure. You should also be cautious when using hot water, as camp showers can get painfully hot.

Tankless propane water heaters

There are a variety of tankless propane water heaters on the market that are perfect for campers. The Camplux PRO, for example, has a heating power of 65000 BTU and a capacity of 2.64 GPM, ensuring you never have to wait long for hot water. The FOGATTI InstaShower 8 Plus is another great option, with a heating power of 55000 BTU and a flow rate of 2.9 GPM. For a more compact and affordable option, the Camplux 5L is a good choice, as it runs off a propane tank and works with a 12-volt pump. While the unit only heats water to around 115 degrees Fahrenheit, it is ideal for quick showers.

When choosing a tankless propane water heater for your camper, consider your hot water requirements, budget, and available space. Additionally, keep in mind that these heaters require proper ventilation and may not be suitable for use at high altitudes.

Water tanks (gas/electric)

Water tanks are a great way to get hot water in your campervan. They are similar to the boilers you would typically find in a house. They work by heating a body of water in a holding tank. They are available in gas or electric-only variants, as well as dual-fuel models that combine both gas and mains power.

Gas Water Tanks

If you are planning on installing gas during your van conversion, it might make sense to utilise this for hot water too. Gas water tanks feature an internal gas burner that heats your water to give you a plentiful supply of hot water. Some feature both electric and gas options, which can speed up the heating time.

Gas water tanks are reliable and safe when fitted correctly. They need to be properly vented and require an onboard gas supply. They are not suitable for use while driving and can take up to 45 minutes to heat up.

Electric Water Tanks

If you are having a hard time deciding between a tankless water heater and a more complicated hot water system, an electric water tank could be something to consider. Electric water tanks are affordable, compact, and work really well. They are also safe and reliable when fitted correctly.

The main downside of an electric water tank is its substantial power draw. If you aren't hooked up to shore power, it will quickly drain your batteries unless you have a really meaty power setup.

Combi heaters (diesel/gas)

Combi heaters are an excellent option for those seeking a dual-purpose heating solution for their campervans. These heaters function as both a blow heater and a water heater, similar to a boiler system in a house. They are usually more expensive than other heating options, but they can save space by serving two purposes in one unit.

Diesel Combi Heaters

Diesel combi heaters are a popular choice for campervan heating and hot water needs. They are known for their efficiency, reliability, and cost-effectiveness. Diesel is also more readily available at petrol stations than LPG, and it burns at a higher BTU, making it a safer option. However, one of the drawbacks of diesel heaters is that they can be louder than LPG heaters and may not function as well at high altitudes.

When choosing a diesel combi heater, consider the size of your campervan and the climate conditions you plan to use it in. For smaller vans, a 2kW heater is usually sufficient, while larger vans or colder climates may require a 5kW heater.

Some features to look for in a diesel combi heater include:

• Automatic altitude adjustment: This feature ensures efficient operation even at high altitudes.
• Safety features: Look for heaters with automatic shut-off in case of overheating or problems with the fuel supply.
• Thermostat or remote control: Allows you to adjust the temperature and control the heater remotely.
• Fuel efficiency: Consider the fuel consumption and runtime of the heater to ensure it meets your needs.
• Installation: Diesel heaters can be tricky to install, so consider seeking professional help if needed.

Gas Combi Heaters

Gas combi heaters, also known as LPG heaters, use LPG (liquefied petroleum gas) as their fuel source. They are similar to diesel combi heaters in that they provide both hot water and space heating. Gas combi heaters are generally quieter than diesel heaters and function better at high altitudes. However, LPG is typically more expensive than diesel, and the gas plumbing must be done perfectly to ensure safety.

When choosing a gas combi heater, consider the following:

• Size and power: Select a heater with sufficient power for the size of your campervan and your heating needs.
• Ventilation: Ensure that the heater has proper ventilation to prevent carbon monoxide buildup.
• Installation: Gas heaters should be installed by a professional to ensure safe and proper functioning.
• Warranty and reliability: Opt for a heater with a good warranty and a reputable brand for added peace of mind.
