Heater and leisure battery

Fatrover · Dec 10, 2022

hello peeps, have decided to bite the bullet and get one of those wee diesel heaters, I’d like to wire it all in myself and am thinking of using a standalone leisure battery. Is this a good idea? I dont want to add much more load to the main battery as I’ve got a heated screen running off that as it is....
Thanks, from a freezing Argyll

How are you going to charge the leisure battery?

I cant see the heater being that much more load, after all how long does a heated screen need to run for? Plus once the heater is running its electrical demand drops right down.

Try and get the heater with this type control panel, you can change a bit incl the fuel pump speed to adjust for elevation/smoke issues etc, some of the others cannot be adjusted.

Lynall I was going to charge it up periodically from the hoose with a battery charger

Thanx Kevstar, i might go with a split charger get the garage to wire it in properly, one batts hardly enough..

You don't want to leave a lead acid battery in a state of partial discharge for too long or damage can occur. Split charging would be a much better option if possible

They take a bit of power to start up and do require a good battery, once started and burning well the power need drops right off.
Lots of threads on FB about fault codes, and every now and then it is a dodgy machine, but generally it is either inadequate power supply or an installation issue, some of the installs are crap beyond belief, exhaust and wiring being the main issues.

Have a look in the projects section.

Diesel heaters use power when off. Not much but enough to drain a battery within a week.

A friend of mine ran his posh electromibob over mine a few weeks ago and I thought the only bit that needed power when off was the controller as it waited for a signal from the remote key fob.
It even drew a bit of power however when I completely disconnected the control box. It seems the circuitry inside the heater also uses a bit of power when shut down.

Excellent info thanks v much, must look deeper into this, dont want any more flat battery dramas!

I have a marine two pin plug nailed to the side of my series. When I park up at night I have a lead from the shed with a charger permanently wired to it. It’s not connected to the main battery but keeps the second battery topped up as I don’t do enough mileage for the split charging to be reliable.
I may have to find a way to include the main starter battery anorl as that also struggles sometimes.
