I've read oilpan4 build link inspirational. The 5kw only helps when the frozen motor is running(can add a 12v pump @aproxamitly 125usd) and a has a 220v plug aka only works at home(this would cost aproxamitly $200 to install a 220v plug out in drive way) or .000005% of other places . That was fine when I lived in Washington/Portland. Now in Montana, having a failed cold start in the woods can be fatal. You are the one who inspired me to dive into setting up non plug-in pre heater as many communitys in Montana are off-grid. The 5kw block heater would require very expensive solor /battery upgrades , I live in town now but plans are in the works for moving to the country. Plan ahead...
Ordered this :

D5wsc 24v manual ,pdf.

Eberspacher Hydronic D5WSC Water Heater 24v | eBay and a 12-24v dc-dc converter $500usd.
Aready had a battery isolator (was to set up a dual battery/ alternator disable system on a previous gaser) , I will be adding a 2nd battery to preserve the starting battery, and give self jump capabilitie.





Any suggestions on additional tags?

Pros
.10gal/hr diesel 3A 24VDC 72W =5KW Hydronic heat + residual ehxsost heat under hood. Most report operating temperature reached in 15min =.025ga fule 18Wh

Will report my actual

During summer the additional battery will allow a altnator disabling switch.

At home I can just plugin a 5A 12V 60w battery float charger at night to avoid 2nd battery.

Can run multiple heating elements ( trans cooler from wrecking yard add a 12 V 5W fan for cab heat parked engine off)

Nomore waiting for heat after a snowshoeing hike.

Cons:
Price 1800usd new with instalation kit got for $500 Ebay
If I can maintain my summer milage ROI should be short.

Extra battery $100+isolator $94 ( needed any way a single battery is almost not enough with 750W stock blook heater pluged in over night @ -30 took 30min idle and 18mi to reach thermostat opening temp).

Cannot be run inside a "tightly sealed grange "
For now not a problem as I have street parking.

Original idea was an instant hot water heater running propane and a 12V pump. Theas heaters are flow activated. So a check valve/isolation solenoid would be needed to prevent heater activation from the engine.

Dreem big chisel down to reality.
