SureCal 35 liter RV vertical calorifier

Please note - the outer shell is very soft, therefore you might see minor cosmetic defects, but they have no impact to the performance of the calorifier.

SureCal calorifiers are manufactured from the best materials available, ensuring durability and reliability. This calorifier stores your hot water, and heats it up using drop coil technology as well as an immersion heater. With the finned surface heat exchanger used in the boiler, heat recovery is unmatched.

Clean water from your onboard water system is warmed up using heat from your engine’s cooling system. The RV water heater also features a standard thermostatic mixer valve, which increases hot water capacity by up to 25 percent.

Benefits of the 35 Liter SureCal:

  • 100% copper calorifier is insulated with a polyurethane jacket

  • The immersion coil retains heat for up to 24 hours after being switched off. 

  • The kit includes complete instructions for quick and easy installation.

  • The calorifier includes an immersion hot water heater, barbed engine coil connections, stainless steel fixing brackets and a pressure release valve.

  • Standard on every unit is a thermostatic mixer valve, which increases availability of hot water.

  • Water stored in the boiler warms up to the same temperature as the immersion coil (85°C / 185°F).

Complete your domestic water circle

In order for your hot water system to function smoothly and securely, only a few essential parts are needed. A complete water circle consists of an expansion tank, an accumulator tank, a water pump, and a calorifier.

An expansion tank is used to protect closed water heating systems and domestic hot water systems from sudden pressure spikes. It can be fitted in any orientation, preferably as close to the calorifier as possible. A 2 liter or 5 liter expansion tank should be sufficient to meet most of your hot water needs in an RV, campervan, or mobile home.

The accumulator tank consists of a water chamber with an internal air bladder that is pre-pressurized. Water pressure 'spikes' are dampened by these devices on the pressured side of your water pump. Water tanks in accumulators conserve battery power, reduce pump cycling, and increase the durability of water pumps.

RVs require water pumps to provide running water, which is essential for living off-grid comfortably. With an onboard water pump, you can wash your hands, fill the sink, flush the toilet, and do many other tasks at home that you take for granted. Normally, a 30PSI water pump is sufficient to provide a comfortable stream of water for RV owners.
