I bought a espar B2L gas heater for my van with a EasyStart Pro controller. Im running a promaster 2500 with Normal gas so I wanted to have a gas heater and not diesel, didnt want an extra auxiliary tank. I had a webasto gas heater in it for a long time, had issues mostly because it was not very tolerant of high altitiude, id have to clean it every 2 uses because of the soot it made. I camp mostly for skiing above 9000ft, which led me to the B2L as it was advertised for up operation to 18kft.
Anyways this heater has never functioned properly, constantly throws codes for voltage, intake issues, and overheating. I eventually sent it back to Heatso and they ran diagnostics on it, said it needed an software update, and allegedly successfully tested it and said it was good to go.
I just reeinstalled it and once again its throwing a overhheating code (P000115). Luckily im not seeing the other voltage codes but still…
Intake/Exhaust are clear. Heater is clean. Wiring is good and delivering 12v to the heater. I have a 500ah battery bank (x4 125ah 12v in parallel) and charged from 220W of Solar (Renogy). The heater is wired direct to the battery per their install instructions and not through a fuse box or solar controller. I NEVER had a problem starting, or running the webasto (just got dirty too fast). The webasto also had a much higher energy demand in comparison.
I imagine if the temperature sensor in the Espar was bad they would have discovered it at Heatso. I thought maybe its because I had it installed in a box style situation but Ive removed that to expose the heater and no changes. Ive had this heater for 2 years and have never had it run more than 30 minutes at a time before code. I reset the codes and can get another 15-30min. You can imagine this isnt very fun in 10 degrees overnight
I am desperate to get this thing working and there is little to no resources for this heater online. I also cannot afford another $1000+ heater. Any advice would be appreciated.
