The Roton D5E Upgrade Kit is a collection of parts commonly required when upgrading from an older model D5 Hydronic (such as D5WSC) to the latest S3 D5E Hydronic.
Note that there were multiple different models and configurations of D5W Hydronics. Some had INTERNAL coolant pumps, and some also had internal fuel pumps. The new D5E is installed with EXTERNAL coolant and fuel pumps.
Upgrading from an older D5W to a new D5E requires the following steps, using the parts provided in the kit:
- Swap heater (new mount is different than old mount)
- Swap old harnesses with new Canbus harnesses
- Swap old thermostat
- Install new external fuel pump (and new fuel pump bracket)
- Install new external coolant pump (and new coolant pump bracket)
- Run new fuel lines (tank to pump and pump to heater)
- Ensure any control/relay wiring used to interlock fan blowers is re-connected to the new heater
As a rule, existing coolant plumbing, expansion tank, fan blowers, and stainless exhaust systems can be re-used when upgrading a hydronic, although we of course recommend a complete inspection to ensure the older parts are still fully serviceable.
