35 liter SureCal Vertical Twin Coil 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.
All SureCal twin coil boilers are made from high-quality materials, which makes them dependable and efficient. The calorifier heats clean water with the excess heat from your engine. In addition, the stored water is heated using drop coil technology and an immersion heater.
The finned surface of the heater exchanger provides unmatched heat recovery. 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:
-
The copper calorifier is insulated with a polyurethane jacket insulation.
-
After being switched off, the immersion coil retains heat for up to 24 hours.
-
Complete instructions are included for quick and easy installation.
-
The calorifier features an immersion hot water heater, stainless steel fixing clamps, and barbed engine coil connections.
-
Thermostatic mixer valves are standard on every unit to ensure an ample supply of hot water.
-
In the boiler, water reaches the same temperature as the immersion coil (85°C / 185°F).
Essentials of your 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.
| Calorifier Size | Recommended Expansion Tank Size |
| 0-22 Liters | 2 Liters |
| 22-55 Liters | 5 Liters |
An accumulator tank consists of a water chamber and a pre-pressurized air bladder. It is installed on the pressurized side of the water pump and dampens pressure spikes in the water system. Water accumulator tanks 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, take a shower, 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.
