Please Note: The outer shell of this unit is relatively soft, which may result in minor cosmetic imperfections. However, these do not affect the performance of the calorifier.
SureCal calorifiers are crafted from high-quality materials to ensure both efficiency and reliability. This model utilizes advanced drop coil technology in conjunction with an immersion heater to warm the stored water. The inclusion of a finned surface heat exchanger allows for superior heat recovery.
The calorifier efficiently uses heat from your engine's cooling system to warm the clean water in your onboard water system. It also features a standard thermostatic mixer valve, which can increase hot water capacity by up to 25%.
Benefits of the SureCal 10-Liter Calorifier:
Complete Your Domestic Water System:
For optimal operation of your hot water system, consider adding a few essential components to complete your water circle. These include:
Expansion Tank: Protects closed water heating and domestic hot water systems from pressure spikes. Install it as close to the calorifier as possible. For RV, campervan, or mobile home use, a 2-liter or 5-liter expansion tank is generally sufficient.
Calorifier Size | Recommended Expansion Tank Size |
---|---|
0-22 Litres | 2 Litres |
22-55 Litres | 5 Litres |
Accumulator Tank: Consists of a water chamber and a pre-pressurized air bladder, installed on the pressurized side of the water pump. It helps to dampen pressure spikes, conserve battery power, reduce pump cycling, and extend pump lifespan.
Water Pump: Essential for running water in RVs. A 30PSI water pump is typically adequate for a comfortable flow for everyday tasks.
SureCal, a UK manufacturer, produces high-quality calorifiers (boilers/water heaters) with BSP threads/connections.
