Caravan Electric Solar Hot Water Systems and Air Heating with Diesel Boost

Electric Solar Hot Water Systems and Air Heating with Diesel Boost for Caravan.

Dieselheat has developed a range of systems to create eco-friendly solar hot water by utilising surplus capacity in your existing solar system and then boosting with a diesel furnace when the sun isn’t shining or you need to run optional air heating.

As DieselHeat say, “Choosing the right air heater for your van or RV is important. With an investment of well over $1000 you want to get it right and there are a few things you definitely need to consider. These include brand, heater size and installation considerations.”

The type of heater, for example; air heating only or air heater and water heater, fuel source, heater location, and the installer are important considerations.  

Typically, a caravan that is less than 21 feet will be fine with a 2kW heater, and longer caravans up to 24 feet are bested heated by a 2.2kW heater. Large RV’s, such as 5th wheelers and buses, Diesel Heat suggest using the 4kW heater. Generally, flat floor campers, pop top Jayco caravans, pop top campers and anything with lots of canvas gets a 2.2kW because canvas loses heat more quickly.

We knew we’d found the solution to our power shortages, caused from heating hot water while off grid, after learning that Dieselheat had developed a diesel caravan heater and hot water system that utilised our existing caravan lithium battery and solar power system.

Using surplus capacity in your existing solar system and then boosting with a diesel furnace when the SUN ISN’T SHINING to heat our hot water and air heating just made sense.

In our Leader Caravan we have chosen the 2v Eberspacher D5E HS3 5kW Hydronic Furnace  optioned with the SureCal Twin Coil Calorifier – 22L for our hot water and hydronic air heating.  This system will replace our existing Truma caravan hot water system and our separate Chinese made caravan diesel heater.

The Eberspacher D5E Furnace is much quieter in terms of the combustion fan and overall noise, plus the heater has a quiet fuel pump, so NO MORE TICKING sound. The high quality UK made hot water tank is designed specifically for caravans, RV’s and off grid solutions and features versatile heating options: 240V | 240V/12v (Solar) | OFF GRID | Engine | Diesel Furnace.  This hot water heating and air heating system is much quieter and a more fuel efficient option than using a generator or gas for heating.

We no longer carrying LPG gas or need to refill caravan gas bottles and can simply enjoy the benefits of hot water and air heating from this one compact setup when free camping off the grid. 

Another benefit of this diesel heating system is the optional 240V element (combined with a 12v solar element) to allow heating when on mains power. Perfect for when staying at a caravan park when a mains connection is available. 

Able to switch between diesel and 12 volt, depending on solar input and current state of battery charge, these caravan hot water systems and caravan air heating systems are well suited for the off grid caravan, camper, RV and marine.

Outech OffGrid Power Solutions supply and install diesel air heaters, electric solar hot water system with diesel boost, diesel hot water and air heaters, and an extensive product range offered by Diesel Heat. Other brands, including Autoterm Diesel Air Heater can also be supplied and installed.
