Espar heaters are among the most popular in the market, and the easy availability of parts and repair shops means installation and maintenance are no hassle at all.

Key features of the Espar D2 Heater Kit

  • The Espar D2 is a 12V diesel powered heater that operates as a forced air heater.
  • It offers a 2.2kW / 7500BTU heat output and has 4 different heating levels – low, medium, high, and power (boost) – so it is easy to achieve the heat level you want.
  • The Espar D2 diesel heater also has an air ventilation mode for circulating cold air through the ducting system, perfect for cooling your cabin or living area on warm nights.
  • It uses an integrated internal temperature sensor for temperature monitoring. An additional external temperature sensor is available and recommended, as this can be placed in locations like your sleeping area and provides higher accuracy and comfort level.
  • The Espar D2 Heater Kit is simple to install and maintain, and comes with all the necessary parts for installation (see full contents of the kit below).
  • It is also compact, which means it can be installed under the passenger seat, in small compartments within your van or trailer, or externally (external mounting requires additional accessories – our customer support team can help you find these).
  • The Espar D2 Heater Kit can operate in altitudes of up to 2,200 meters / 7200 feet, and can be used at even higher altitudes with an additional High Altitude Kit.
  • The Espar D2 uses CAN, LIN and S+ system communication protocols which means it is compatible with early generation controllers. So you can use the controller from your previous models of heater with your new Espar D2.

User benefits of the Espar D2 Heater Kit

The Espar D2 diesel heater is the most reliable and powerful 2kW heater on the market. Diesel powered with a 2.2kW / 7500BTU heat output, it is easy to install and even easier to maintain. What’s more, it is compact, meaning it can be installed under the passenger seat, small compartments or externally (external mounting accessories are required). And beyond convenience, there’s the accuracy of temperature control that you associate with Espar diesel heaters. And for extra accuracy, you can purchase an external temperature unit for your Espar D2 heater that can override the internally mounted temperature sensor to provide you the highest level of temperature control. There are 4 heating levels – low, medium, high, power, and an air ventilation mode to help you cool down your vehicle or living space. The unit also comes with enhanced on screen diagnostics, making it easier for you to catch any issues as they appear.

What really sets the Espar D2 Heater kit apart from other economical heaters is its ability to be used at high altitudes. Espar’s unique altitude adjustment feature means that it can work at 2200 meters, around 700 meters higher than its competitors, and if you want to use your Espar D2 even higher than that, you can purchase the special High Altitude kit.  And if you are the kind of person who likes to have the ability to finetune your heater kit, you’ll find that the Espar D2 Heater is customisable. As it uses LIN, CAN and S+ technologies, it gives you greater freedom for custom control builds.
