DESCRIPTION OF THE HEATING SYSTEM

The Alde Compact 3020 boiler (figure 1) is designed to provide both heat and hot water.
The heating system includes both an LP Gas burner and an electric heating element and you can use the system with
either LP Gas, electricity or both.
The heating system consists of the boiler unit as well as an expansion tank, which is installed at the highest point
the RV. Check with your RV owner's manual to determine where the expansion tank is installed. The heating system
works by circulating hot glycol fluid through pipes and heat convector's, similar to the heating system used in many
homes.
The heating system is fitted with a 12-volt electrical circulation pump that is used to circulate the heated fluid. The heat
convector's located near the floor of the RV allow air to be heated by the hot fluid in the system and then the air rises
and circulates to heat the space in your RV. The heating system is also fitted with a built-in hot water boiler that has a
volume of approx. 2.5 gallons (8.4 liters) of fresh water.
The LP Gas boiler in the heating system can produce around 3 gallons (12 liters) of 104 °F (40 °C) water every half-
hour. If the electric heating elements are used instead of gas for powering the heating system, the capacity is slightly
less. You may use the heating system to heat the RV without filling the hot water boiler.
