Winterize the Hydro Hot systems before freezing temperatures of winter set in. Use the
RV water pump to move the antifreeze through the system until the solution is detected
at the hot water faucet.
When it is time to take the RV out of winter storage, flush the domestic water system
with clear water. Give the hydronic heating system a tune up by replacing the fuel
nozzle and fuel filter, clean out the combustion chamber, and inspect the system for
any signs of wear and tear.
Service
Once per year, have the Hydro-Hot system tuned up by a qualified technician to assure
ongoing performance of the system when needed. When storing the RV during freez-
ing temperatures, winterize by draining the Hydro-Hot system of water. The Hydro-Hot
system is still available for use in interior heating during storage following winteriza-
tion.
hydronic heating system.
Routinely inspect the system’s overflow bottle to monitor antifreeze levels, and add
additional antifreeze as needed. Check fluid levels when the burner cycles off. The
level should be at full hot. Keep a fresh supply of cleaning rags handy to wipe up spills
as they occur.
Store RV antifreeze in the original container and away from heat. If it becomes neces-
sary to throw away left over or used RV antifreeze, securely cap the container, insure
that the receptacle is clearly marked, and carefully adhere to local laws regarding the
proper disposal of hazardous material.
Winterizing
You may normally keep the RV plugged into shore power during cold winter months
and presume that it is unnecessary to maintain antifreeze levels within the hydronic
heating system. Relying on continuous shore power supply to protect the Aqua Hot
system from freezing is risky when taking into account that the shore power supply
may be interrupted due to a black out, or because the shore power cord has inadver-
tently disconnected from the source.
In preparation for winter storage, drain potable water and all the low point drains in
the RV. The Hydro Hot system will require specific steps in winterizing. Evacuating the
hydronic heating system of water when preparing the RV for winter storage by blowing
out the lines with compressed air may not be effective in completely draining water out
of the long length of tubes inside of the system. Moisture left within the tubes could
collect and settle at the bottom loop. If temperatures during storage reach freezing,
that moisture may expand and crack the tubes.
